1.	Alm, Per A (författare) Copper in developmental stuttering. 2005 Ingår i: Folia Phoniatrica et Logopaedica. - : S. Karger AG. - 1021-7762 .- 1421-9972. ; 57:4, s. 216-222 Tidskriftsartikel (refereegranskat)abstract It has previously been reported that men with developmental stuttering showed reduced concentration of copper in the blood, and a negative correlation between the copper level and the severity of stuttering. Disorders of copper metabolism may result in dysfunction of the basal ganglia system and dystonia, a motor disorder sharing some traits of stuttering. It has been shown that copper ions affect the dopamine and the GABA systems. With this background we investigated the plasma level of copper, the copper binding protein ceruloplasmin, and the estimated level of free copper in stuttering adults. Sixteen men with developmental stuttering were compared with 16 men without speech problems. The samples were assayed in one batch in a pseudorandom and counterbalanced order. No significant differences were found between stuttering men and the control group in any of the biological variables, and no negative correlation between copper and the general severity of stuttering was shown. On the contrary, an explorative analysis resulted in a positive correlation between high plasma copper and superfluous muscular activity during stuttering (r = 0.51, p = 0.04). This result indicates that there is no relation between developmental stuttering and low plasma copper in the main population of stuttering adults.
2.	Echternach, Matthias, et al. (författare) Professional Opera Tenors' Vocal Tract Configurations in Registers 2010 Ingår i: Folia Phoniatrica et Logopaedica. - : S. Karger AG. - 1021-7762 .- 1421-9972. ; 62:6, s. 278-287 Tidskriftsartikel (refereegranskat)abstract Objective: Tenor singers may reach their top pitch range either by shifting from modal to falsetto register or by using their so-called 'voix mixte'. Material and Methods: In this study, dynamic real-time MRI of 8 frames per second was used to analyze the vocal tract profile in 10 professional opera tenors, who sang an ascending scale from C4 (262 Hz) to A4 (440 Hz) on the vowel /a/. The scale included their register transition and the singers applied both register techniques in different takes. Results: Modal to falsetto register changes were associated with only minor vocal tract modifications, including elevation and tilting of the larynx and a lifted tongue dorsum. Transitions to voix mixte, by contrast, were associated with major vocal tract modifications. Under these conditions, the subjects widened their pharynges, their lip and jaw openings, and increased their jaw protrusion. These modifications were stronger in more 'heavy' tenors than in more 'light' tenors. The acoustic consequences of these articulatory changes are discussed.

(författare) Long-term follow-up of patients with spasmodic dysphonia and improved voice despite discontinuation of treatment 2017 Ingår i: Folia Phoniatrica et Logopaedica. - : S. Karger. - 1021-7762 .- 1421-9972. ; 68:3, s. 144-151 Tidskriftsartikel (refereegranskat)abstract Objective: To evaluate voice function in patients with adductor spasmodic dysphonia (AdSD) who discontinued botulinum toxin (BTX) treatment because they felt that their voice had improved sufficiently. Patients and Methods: Twenty-eight patients quit treatment in 2004, of whom 20 fulfilled the inclusion criteria for the study, with 3 subsequently excluded because of return of symptoms, leaving 17 patients (11 males, 6 females) included in this follow-up study. A questionnaire concerning current voice function and the Voice Handicap Index were completed. Audio-perceptual voice assessments were done by 3 listeners. The inter- and intrarater reliabilities were r > 0.80. Results: All patients had a subjectively good stable voice, but with differences in their audio-perceptual voice assessment scores. Based on the pre-/posttreatment auditory scores on the overall degree of AdSD, patients were divided into 2 subgroups showing more and less improvement, with 10 and 7 patients, respectively. The subgroup with more improvement had shorter duration from the onset of symptoms until the start of BTX treatment, and included 7 males compared to only 4 males in the subgroup with less improvement. Conclusion: It seems plausible that the symptoms of spasmodic dysphonia may decrease over time. Early intervention and male gender seem to be important factors for long-term reduction of the voice symptoms of AdSD.
4.	Gillberg, Christopher, 1950 (författare) Hyperactivity, inattention and motor control problems: prevalence, comorbidity and background factors 1998 Ingår i: Folia Phoniatrica et Logopedica. - : S. Karger AG. - 1021-7762 .- 1421-9972. ; 50:3, s. 107-117 Tidskriftsartikel (refereegranskat)abstract This paper provides a brief review of syndromes associated with activity dysregulation, inattention and motor control problems, usually referred to as attention-deficit/hyperactivity disorder, developmental coordination disorder and deficits in attention, motor control and perception. Several percent of school age children are affected by such problems. Disorders tend to overlap and show significant comorbidities. Familial and brain-damaging factors are involved in the pathogenesis and appear to impinge on specific attentional brain systems. Outcome is variable but restricted if appropriate diagnosis/intervention is not accomplished. Effective interventions are available. Given the high prevalence of these disorders and their relatively poor outcome, such interventions could constitute effective prevention in a general population health perspective.

Hammarberg, B (författare) Voice research and clinical needs 2000 Ingår i: Folia phoniatrica et logopaedica : official organ of the International Association of Logopedics and Phoniatrics (IALP). - : S. Karger AG. - 1021-7762. ; 52:1-3, s. 93-102 Tidskriftsartikel (refereegranskat)abstract The purpose of this paper is to provide a review of recent advances in voice research with special focus on clinical aspects and on the speaking voice. First an update on histological findings concerning the multilayer structure and the biomechanics of the vocal folds is given. Other topics are vocal fold closure patterns, the development of the voice from childhood to senescence, and theoretical aspects of vocal function from an acoustic-aerodynamic point of view. Special emphasis is put on voice parameters, which can be assumed to be relevant to underlying physiology, and how they can be captured by different techniques.
6.	Hartelius, Lena, 1957 (författare) Incidence of Developmental Speech Dysfluencies in Individuals with Parkinson's Disease 2014 Ingår i: Folia Phoniatrica Et Logopaedica. - : S. Karger AG. - 1021-7762 .- 1421-9972. ; 66:3, s. 132-137 Tidskriftsartikel (refereegranskat)abstract Objective: The aim of this study was to investigate the incidence of developmental speech dysfluencies in individuals with Parkinson's disease (PD). Background: The possible relationship between PD and dysfluencies such as stuttering has engaged researchers for many years. However, whether there is a higher-than-expected incidence of reported childhood stuttering in adults with a diagnosis of PD is unknown. Participants and Methods: A questionnaire including items regarding present and former speech difficulties was answered by 280 individuals with PD. Results: The total number of persons who reported that they had stuttered (often or sometimes) before the age of 10 years was 11, corresponding to 3.9%. The number of persons who reported unusually fast speech before the age of 10 years was 17, corresponding to 6.1%. The reported incidence of childhood stuttering in this group was consequently not higher than that in previously published reports on childhood stuttering (approx. 5%). The frequency of unusually fast speech was notable, but the lack of a control group made it difficult to conclude on the significance of that finding. Conclusion: Although no direct comparison between self-reported incidences of childhood dysfluencies and published incidence figures regarding childhood stuttering can be made, different possible relationships between speech dysfluency and basal ganglia dysfunction are discussed.

7.	Hartelius, Lena, 1957, et al. (författare) Living with dysarthria: evaluation of a self-report questionnaire. 2008 Ingår i: Folia phoniatrica et logopaedica : official organ of the International Association of Logopedics and Phoniatrics (IALP). - : S. Karger AG. - 1421-9972. ; 60:1, s. 11-9 Tidskriftsartikel (refereegranskat)abstract The study describes an effort to evaluate the speech difficulties as perceived by individuals with dysarthria. A self-report questionnaire, Living with Neurologically Based Speech Difficulties (Living with Dysarthria), was answered by 55 individuals with varying types and degrees of dysarthria. Results show that both type and degree of subjectively perceived communicative difficulties varied. Degree of communicative difficulties was not related to age, gender, diagnosis, disease duration or employment status in this group. Generally, the overriding problems were related to restrictions in communicative participation, possibilities to actively take part in work and studies and to express one's personality were particularly affected. Communication was also affected by emotions and by the number and familiarity of people present in communicative encounters. The dominating speech difficulties were related to reduced speech rate and a need for repetition as a consequence of misunderstandings. A statistically nonsignificant difference was found between the higher mean of the group with moderate dysarthria compared to the groups with severe and mild dysarthria, indicating that severity of dysarthria does not necessarily predict extent of perceived communicative difficulties. It is concluded that systematic subjective reports should always be included in the assessment of individuals with acquired dysarthria.
8.	Hartelius, Lena, 1957, et al. (författare) Short-term effects of repetitive transcranial magnetic stimulation on speech and voice in individuals with Parkinson's disease. 2010 Ingår i: Folia phoniatrica et logopaedica : official organ of the International Association of Logopedics and Phoniatrics (IALP). - : S. Karger AG. - 1421-9972. ; 62:3, s. 104-9 Tidskriftsartikel (refereegranskat)abstract The main characteristics of dysarthria in Parkinson's disease (PD) are monotony of pitch and loudness, reduced stress, variable speech rate, imprecise consonants, and breathy and harsh voice. Earlier treatment studies have shown that dysarthria is less responsive to both pharmacological and surgical treatments than other gross motor symptoms. Recent findings have suggested that repetitive transcranial magnetic stimulation (rTMS) may have a beneficial effect on vocal function in PD. In the present study, 10 individuals with mild PD and no or minimal dysarthria were treated with rTMS as well as placebo stimulation in a blinded experiment. Stimulation was delivered using a frequency of 10 Hz and a stimulation intensity of 90% of the motor threshold. The site of stimulation was the cortical area corresponding to the hand, on the hemisphere contralateral to the patient's most affected side. The participants were audio-recorded before and after both rTMS and sham stimulation. Acoustic analysis was performed on 3 sustained /a:/ for each of the 4 conditions, and analyzed both for the whole group as well as for men and women separately. Results showed that there were no significant differences between any of the conditions regarding duration of sustained fricative or sustained vowel phonation, diadochokinetic rates or intelligibility. Above all, the results of acoustic analyses showed an effect of placebo; there was a significant reduction in fundamental frequency (F(0)) variation, pitch period perturbation, amplitude period perturbation, noise-to-harmonics ratio and coefficient of variation in F(0) between the recordings performed before compared to after sham stimulation.
9.	Hartelius, Lena, 1957, et al. (författare) Speech and swallowing symptoms associated with Parkinson's disease and multiple sclerosis: a survey. 1994 Ingår i: Folia phoniatrica et logopaedica : official organ of the International Association of Logopedics and Phoniatrics (IALP). - 1021-7762. ; 46:1, s. 9-17 Tidskriftsartikel (refereegranskat)abstract A survey of approximately 460 patients with Parkinson's disease (PD) or multiple sclerosis (MS) shows that speech and swallowing difficulties are very frequent within these groups. Seventy percent of the PD patients and 44% of the MS patients had experienced impairment of speech and voice after the onset of their disease. Forty-one percent of the PD patients and 33% of the MS patients indicated impairment of chewing and swallowing abilities. The speech disorder was regarded as one of their greatest problems by 29% of the PD patients and by 16% of the MS patients. Only a small number of patients, 3% of the PD and 2% of the MS group, had received any speech therapy.
10.	Havel, Miriam, et al. (författare) Contribution of Paranasal Sinuses to the Acoustic Properties of the Nasal Tract 2014 Ingår i: Folia Phoniatrica et Logopaedica. - : S. Karger AG. - 1021-7762 .- 1421-9972. ; 66:3, s. 109-114 Tidskriftsartikel (refereegranskat)abstract Background: The contribution of the nasal and paranasal cavities to the vocal tract resonator properties is unclear. Here we investigate these resonance phenomena of the sinonasal tract in isolation in a cadaver and compare the results with those gained in a simplified brass tube model. Methods: The resonance characteristics were measured as the response to sine sweep excitation from an earphone. In the brass model the earphone was placed at the closed end and in the cadaver in the epipharynx. The response was picked up by a microphone placed at the open end of the model and at the nostrils, respectively. A shunting cavity with varied volumes was connected to the model and the effects on the response curve were determined. In the cadaver, different conditions with blocked and unblocked middle meatus and sphenoidal ostium were tested. Additionally, infundibulotomy was performed allowing direct access to and selective occlusion of the maxillary ostium. Results: In both the brass model and the cadaver, a baseline condition with no cavities included produced response curves with clear resonance peaks separated by valleys. Marked dips occurred when shunting cavities were attached to the model. The frequencies of these dips decreased with increasing shunting volume. In the cadaver, a marked dip was observed after removing the unilateral occlusion of the middle meatus and the sphenoidal ostium. Another marked dip was detected at low frequency after removal of the occlusion of the maxillary ostium following infundibulotomy. Conclusion: Combining measurements on a simplified nasal model with measurements in a cadaveric sinonasal tract seems a promising method for shedding light on the acoustic properties of the nasal resonator.
11.	Johansson, Inga-Lena, 1967-, et al. (författare) Picture description in the assessment of connected speech intelligibility in Parkinson's disease : A pilot study 2022 Ingår i: Folia Phoniatrica et Logopaedica. - Basel, Switzerland : S. Karger. - 1021-7762 .- 1421-9972. ; 74:5, s. 320-334 Tidskriftsartikel (refereegranskat)abstract Introduction: Assessment of intelligibility in dysarthria tends to rely on oral reading of sentences or words. However, self-generated utterances are closer to a clients’ natural speech. This study investigated how transcription of utterances elicited by picture description can be used in the assessment of intelligibility in speakers with Parkinson’s disease.Methods: Speech samples from eleven speakers with Parkinson’s disease and six neurologically healthy persons were audio-recorded. Forty-two naive listeners completed transcriptions of self-generated sentences from a picture description task and orally read sentences from the Swedish Test of Intelligibility, as well as scaled ratings of narrative speech samples.Results: Intelligibility was higher in orally read than self-generated sentences and higher for content words than for the whole sentence in self-generated sentences for most of the speakers, although these within-group differences were not statistically significant at group level. Adding contextual leads for the listeners increased intelligibility in self-generated utterances significantly, but with individual variation. Although correlations between the intelligibility measures were at least moderate or strong, there was a considerable inter- and intra-speaker variability in intelligibility scores between tasks for the speakers with Parkinson’s disease, indicating individual variation of factors that impact intelligibility. Intelligibility scores from neurologically healthy speakers were generally high across tasks with no significant differences between the conditions.Conclusion: Within-speaker variability supports literature recommendations to use multiple methods and tasks when assessing intelligibility. The inclusion of transcription of self-generated utterances elicited by picture description to the intelligibility assessment has the potential to provide additional information to assessment methods based on oral reading of pre-scripted sentences and to inform the planning of interventions.
12.	Johansson, K., et al. (författare) Self-Reported Changes in Cognition, Communication and Swallowing in Multiple Sclerosis: Data from the Swedish Multiple Sclerosis Registry and from a National Survey 2021 Ingår i: Folia Phoniatrica Et Logopaedica. - : S. Karger AG. - 1021-7762 .- 1421-9972. ; 73:1, s. 50-62 Tidskriftsartikel (refereegranskat)abstract Purpose: The aim of this study was to investigate self-reported cognition, speech, communication and swallowing changes in a large sample of individuals with multiple sclerosis (MS) in Sweden. A second aim was to update information about speech and language pathology (SLP) services received by people with MS (pwMS). Method: Self-ratings of cognition, speech/communication and swallowing registered by pwMS between 2012 and 2018 were retrieved from the Swedish MS Registry. In addition, more detailed information about speech, communication, swallowing and provision of SLP services was collected using an online survey distributed via a national patient organization. Results: In total, entries from 5,289 pwMS were retrieved from the MS Registry. Nearly two thirds of the respondents reported that cognition was affected to some degree, whereas approximately one third perceived some difficulties with speech/communication. A smaller group reported swallowing problems. The majority of those who reported problems with speech/communication also reported problems with cognition. Among the 440 individuals who responded to the MS survey, word-finding difficulties were the most frequently self-reported problem related to communication, and the second most common problem was getting off topic. In all, close to four out of five respondents experienced at least one symptom related to speech and communication, such as speech-related fatigue or imprecise articulation. Swallowing difficulties were reported by one out of four respondents in the MS survey. As a result of their speech difficulties, up to one in three experienced changes in professional or social roles and participation. A limited number of respondents had received SLP services, the most common intervention being voice training. Conclusions: In MS, changes associated with cognition as well as speech/communication are frequent, cognitive-linguistic symptoms being the most common. Swallowing difficulties are also relatively prevalent. Access to SLP services seems to be insufficient compared to prevalence of perceived symptoms. Considering that the majority of pwMS are part of the working-age population, access to SLP services must be more highly prioritized and must address cognitive-linguistic problems as well as voice, speech and swallowing dysfunction.

13.	Karlsson, Fredrik, Docent, 1975-, et al. (författare) How Well Does Diadochokinetic Task Performance Predict Articulatory Imprecision? : Differentiating Individuals with Parkinson's Disease from Control Subjects 2019 Ingår i: Folia Phoniatrica et Logopaedica. - : S. Karger. - 1021-7762 .- 1421-9972. ; 71:5-6, s. 251-260 Tidskriftsartikel (refereegranskat)abstract OBJECTIVE: To investigate whether syllables produced in an oral diadochokinetic (DDK) task may be quantified so that persons with Parkinson's disease (PD) perceived to have reduced articulatory precision when reading may be correctly identified using that quantification.PATIENTS AND METHODS: Syllable sequences from 38 speakers with PD and 38 gender- and age-matched control speakers (normal controls [NC]) were quantified acoustically and evaluated in terms of (1) the speakers' ability to accurately predict speaker group membership (PD or NC) and (2) their ability to predict reduced/non-reduced articulatory precision.RESULTS: A balanced accuracy of 80-93% in predicting speaker group membership was achieved. The best measures were related to the proportion of a syllable made up of a vowel, amplitude slope and syllable-to-syllable variation in duration and amplitude. The best material was that based on /ka/. Reduced articulatory precision was accurately predicted from DDK measures in 89% of the samples. Release-transient prominence and voicing during the onset of plosives were particularly strong predictors.CONCLUSIONS: DDK sequences can predict articulatory imprecision as observed in another speech task. The linking of performance across speech tasks probably requires measures of stability in syllable durations and amplitudes, as well as measures of subsyllabic acoustic features.

Karger AG. - 1021-7762 .- 1421-9972. ; 65:6, s. 294-302 Tidskriftsartikel (refereegranskat)abstract Objective: This investigation analyzes flow glottogram and electroglottogram (EGG) parameters as well as the relationship between formant frequencies and partials in two male Kunqu Opera roles, Colorful face (CF) and Old man (OM).Participants and Methods: Four male professional Kunqu Opera singers volunteered as participants, 2 singers for each role. Using inverse filtering of the audio signal flow glottogram parameters and formant frequencies were measured in each note of scales. Two EGG parameters, contact quotient (CoQ) and speed quotient, were measured.Results: Formant tuning was observed only in 1 of the OM singers and appeared in a pitch range lower than the passaggio range of Western male opera singers. Both the CF and the OM role singers showed high CoQ values and low values of the normalized amplitude quotient in singing. For 3 of the 4 singers CoQ and the level difference between the first and second partials showed a positive and a negative correlation with fundamental frequency (F0), respectively.Conclusions: Formant tuning may be applied by a singer of the OM role, and both CF and OM role singers may use a rather pressed type of phonation, CF singers more than OM singers in the lower part of the pitch range. Most singers increased glottal adduction with rising F0.

Karger AG. - 1421-9972. ; 63:3, s. 161-167 Tidskriftsartikel (refereegranskat)abstract <i>Objective:</i> A new method, air pulse pliability measurement, is presented, with which the pliability and elasticity of the vocal folds was measured in vitro and in vivo using air pulses. The size of the mucosal movements induced by air pulse stimulation was measured with a laser-based technique. <i>Subjects and Methods:</i> The air pulses fed via a 2-mm tubing, introduced through the working channel of a flexible endoscope. Both in vitro and in vivo tests were performed. Nine normal, vocally healthy subjects were examined by air pulse stimulations of the vocal folds, of the skin (cheek and dorsum of the hand) and of the inside of the lips. <i>Results:</i> The in vitro tests showed a coefficient of variation of 5% within a range of 1–5 mm from the probe to the surface. The elasticity data showed no differences between vocal folds, lips or cheek. The hand data showed a significantly higher stiffness as compared to the other 3 measuring points (p < 0.001). The coefficient of variation was about 35% for all measuring points, but in ideal conditions on skin it was 9%. <i>Conclusion:</i> The results show that the technique allows automatic, quantitative, noninvasive vocal fold pliability measurements on awake subjects.

Acoustical analyses were made of voice aspects and temporal speech aspects. Self-assessments of voice were made with the Voice Handicap Index (VHI). <i>Results:</i> Perceptual assessment of TE speech showed significant correlations between overall degree of deviation and low speaking rate, deviant articulation, monotonous intonation, roughness and low pitch. The overall degree of deviation correlated significantly with acoustical measurements of speaking rate, articulation rate, and phrase length. Significant correlations were also found between assessed pitch and measured fundamental frequency, between assessed speaking rate and measured number of words per minute, and between assessed phrase length and measured number of syllables per breath. Self-assessments of VHI were significantly correlated with voice intensity and temporal speech aspects such as total reading time, phrase length, and percent pause time. No significant correlations were found between perceptual assessment and VHI degree. <i>Conclusion:</i> The listeners’ ratings of overall degree of deviation in TE speech showed relations to both voice quality and temporal aspects in speech. The TE speakers’ voice handicap degree were mainly related to changes in temporal aspects of speech.

Evaluation of voice handicap was done with the VHI. HRQL was evaluated with questionnaires from the European Organization for Research and Treatment of Cancer, EORTC QLQ-C30 and EORTC QLQ-H&N35. <i>Results:</i> VHI for the whole group demonstrated a moderate voice handicap, with a mean score of 48/120. The functional scales of EORTC QLQ-C30 resulted in scores on the same level as the normal population with the exception of a lower global quality of life scale (Global QOL). EORTC QLQ-H&N35 revealed problems with smell and taste, speech, coughing, xerostomia, and sexuality. VHI correlated significantly with the Global QOL, the functional scales, dyspnea, pain, nausea and financial difficulties (EORTC QLQ-C30). Significant correlations were also found between VHI and speech problems, social contact, pain from the head and neck area, sense problems, sexuality and social eating (EORTC QLQ-H&N35). <i>Conclusion:</i> The EORTC questionnaires in combination with the VHI questionnaire seem to capture most of the problems following laryngectomy, including voice problems.

Karger AG. - 1421-9972. ; 69:3, s. 125-130 Tidskriftsartikel (refereegranskat)abstract <b><i>Objective:</i></b> Vocal fold scarring (VFS) and sulcus vocalis (SV) often result in severe and chronic voice disorders. This study compares subjective voice complaints as rated with the Voice Handicap Index and etiological factors for patients with VFS and SV. <b><i>Patients and Methods:</i></b> Data were collected from the medical records at the Department of Otorhinolaryngology, Karolinska University Hospital, for 27 VFS patients and 27 SV patients. Descriptive background factors were compared between the groups and data were compared from the Swedish Voice Handicap Index (Sw-VHI) questionnaires. <b><i>Results:</i></b> Previous laryngeal surgery/trauma was significantly more common for the patients with VFS. The SV group had significantly more persistent dysphonia since childhood. It was significantly more common to have a non-Germanic language origin among the SV patients. VFS and SV rated high for the total median Sw-VHI scores. The VFS group’s total Sw-VHI and the three domain scores were significantly higher compared to the SV group. The physical domain showed a significantly higher score when compared to the functional and emotional domains in the SV cohort and when compared to the emotional domain in the VFS cohort. <b><i>Conclusion:</i></b> There are significant differences between the VFS group and SV group regarding etiological factors as well as the Sw-VHI. The degree and profile of VHI should be considered when selecting patients and evaluating the result of new treatments for this group of patients.

Neurologic diseases were the most commonly diagnosed conditions in the patients tested (48.3%). Informed consent was obtained from all subjects. <b><i>Results:</i></b> Our study showed minor side effects (discomfort, occasional gagging and vomiting) and a few complications [three cases of anterior epistaxis (0.1%), one case of posterior epistaxis (0.04%), three cases of vasovagal syncope (0.1%) and two cases of laryngospasm (0.07%)]. These cases of laryngospasm occurred in patients with amyotrophic lateral sclerosis (ALS) and spontaneously resolved after some difficulty. <b><i>Conclusions:</i></b> Our study confirms the published data regarding the safety of FEES and the incidence of complications with this procedure, but also highlights that in neurologic patients with neurodegenerative diseases such as ALS, laryngospasm is more likely to occur as a severe complication. The overall risk of FEES is minimal, but it is recommended that clinicians be well trained in recognising the signs and symptoms of adverse reactions and be ready to take appropriate action if these occur.

Different 9- and 12-item subsets were selected from the 30 VHI items using (1) the first factor of an unrotated factor analysis (narrow range subsets) and (2) the first three factors after promax rotation (broad range subsets). Country-specific subsets were selected to test deviations from the international subsets. For all subsets, reliability was investigated using Cronbach’s alphas and correlations with the total VHI. Validity was investigated using regression on voice disorder groups. All analyses were performed for the total and for all country-specific subject samples. <i>Results:</i> Reliability was high for all item subsets. It was lower for the international compared to the country-specific subsets and for the broad range compared to the narrow range subsets. Validity was best for the broad range subsets. Validity was better for the international than for the country-specific subsets. For all statistics the 12-item subsets were not essentially better than the 9-item subsets. <i>Conclusion:</i> The international broad range 9-item subset forms a scale which approximates well the total VHI.
22.	Pirila, Sirpa, et al. (författare) Relationship between Activity Noise, Voice Parameters, and Voice Symptoms among Female Teachers 2017 Ingår i: Folia Phoniatrica et Logopaedica. - : S. Karger AG. - 1021-7762 .- 1421-9972. ; 69:3, s. 94-102 Tidskriftsartikel (refereegranskat)abstract Objective: Our interest was in how teachers’ voices behave during the delivery of lessons in core subjects (e.g., mathematics, science, etc.). We sought to evaluate the relationship between voice sound pressure level (SPL), vocal fundamental frequency (F0), voice symptoms, activity noise, and differences therein during the first and the last lessons in core subjects of the day. Patients and Methods: The participants were 24 female elementary school teachers. Voice symptoms were evaluated by questionnaire. The data were recorded on 2 portable voice accumulators (VoxLog) from the first and last lessons of the day. The versions of accumulators differed by frequency weighting; therefore, the analysis and the results of noise and voice SPL were treated separately: unweighted (group 1) and A-weighted (group 2). Results: Difference in voice SPL followed difference in activity noise. F0 increased between the first and last lessons. Correlations were found between differences in the noise and the voice symptoms of tiredness and dryness. Irritating mucus was associated with high F0 during the first lesson. Conclusion: An apparent increase in voice loading due to the activity noise was observed during lessons in core subjects. Collaboration between specialists in voice and acoustics and teachers and pupils is needed to reduce this voice loading.

Karger AG. - 1021-7762 .- 1421-9972. ; 57:2, s. 90-95 Tidskriftsartikel (refereegranskat)abstract In a prospective study we tested the hypothesis that a cry from an infant can be used as part of an instrument to measure pain. Ten healthy newly born infants were subjected to painful stimuli on four occasions during their first year of life. The sound of the crying was analysed with regard to duration. With the help of a sound spectrogram, the fundamental frequencies of the first five crying sounds were analysed. The number of crying sounds decreased with age. There was a considerable difference between the 10 children, and also between the different pricking occasions for the respective children. We conclude that if crying is to be used as part of an instrument for measuring pain, the child's age has to be taken into account.

(författare) Acoustic analysis of speech tasks performed by three individuals with spinocerebellar ataxia. 2004 Ingår i: Folia phoniatrica et logopaedica : official organ of the International Association of Logopedics and Phoniatrics (IALP). - : S. Karger AG. - 1021-7762 .- 1421-9972. ; 56:6, s. 367-80 Tidskriftsartikel (refereegranskat)abstract A number of speech tasks produced by three female subjects with different types of genetically diagnosed spinocerebellar ataxia and with mild dysarthria were investigated using acoustic instrumentation. All subjects showed a number of signs of decreased speech rate, increased pause duration, increased and more variable durations of alternating motion rate, sequential motion rate syllables and inter-stress intervals in addition to vocal instability. These signs were consistent with the perceptual judgment of ataxic dysarthria. Furthermore, the severity of impairment found using these speech analysis methods seemed to correspond to the general severity of the disease and the duration of the illness in these few subjects. The tasks studied appeared to be relevant and suitable for acoustic analyses as they did reveal deviations in the speech of the subjects compared with controls.

Karger AG. - 1021-7762 .- 1421-9972. ; 69:3, s. 131-141 Tidskriftsartikel (refereegranskat)abstract Background: Changes in communicative functions are common in Parkinson's disease (PD), but there are only limited data provided by individuals with PD on how these changes are perceived, what their consequences are, and what type of intervention is provided. Aim: To present self-reported information about speech and communication, the impact on communicative participation, and the amount and type of speech-language pathology services received by people with PD. Methods: Respondents with PD recruited via the Swedish Parkinson's Disease Society filled out a questionnaire accessed via a Web link or provided in a paper version. Results: Of 188 respondents, 92.5% reported at least one symptom related to communication; the most common symptoms were weak voice, word-finding difficulties, imprecise articulation, and getting off topic in conversation. The speech and communication problems resulted in restricted communicative participation for between a quarter and a third of the respondents, and their speech caused embarrassment sometimes or more often to more than half. Forty-five percent of the respondents had received speech-language pathology services. Conclusions: Most respondents reported both speech and language symptoms, and many experienced restricted communicative participation. Access to speech-language pathology services is still inadequate. Services should also address cognitive/linguistic aspects to meet the needs of people with PD. (C) 2018 S. Karger AG, Basel

Karger AG. - 1021-7762 .- 1421-9972. ; 73:2, s. 101-108 Tidskriftsartikel (refereegranskat)abstract Background: Communication is affected in most people with amyotrophic lateral sclerosis (ALS); up to 80–95% will reach a point where they are no longer able to meet their communicative needs with natural speech. The deterioration of speech and communicative abilities presumably has an impact on communicative participation. However, little is known about how these factors relate to each other in this population of patients. Objective: This study aimed to investigate the association between communicative participation, functional deficits, and severity of dysarthria in individuals with ALS. Method: Thirty people with ALS were rated for (1) communicative participation, using the Communicative Participation Item Bank (CPIB, Swedish); and (2) disability related to the disease, using the Revised ALS Functional Rating Scale (Swedish). An expert listening panel assessed intelligibility and severity of dysarthria based on recorded text readings and sentences from the Swedish Test of Intelligibility. Results: CPIB scores were significantly lower for participants with moderate/severe dysarthria than for those with no/mild dysarthria and correlated with bulbar function and intelligibility. Conclusion: The study found that the CPIB provides a means to rate and discuss communicative participation with persons with ALS, which could assist in the planning of further efforts/services.

(författare) Cultural and Linguistic Practice with Children with Developmental Language Disorder : Findings from an International Practitioner Survey 2021 Ingår i: Folia Phoniatrica et Logopaedica. - Switzerland : S. Karger. - 1021-7762 .- 1421-9972. ; 73, s. 465-477 Tidskriftsartikel (refereegranskat)abstract Background: The cultural and language diversity across many European countries presents a range of challenges and opportunities for speech and language therapists and other practitioners working with children with developmental language disorders (DLD) and their families. Objective: The aim of this study was to explore practitioners' perceptions of cultural and linguistic differences in response to children with DLD across different countries. Methods: A survey was developed by practitioners and researchers working with children with DLD across Europe and beyond as part of the work of Cost Action IS1406. Data from 1,358 practitioners from 8 European countries - Ireland, UK, Bulgaria, Poland, Croatia, Spain, Norway and Sweden - and 2 neighbour countries - Turkey and Lebanon - were included in the present analyses, which address two groups of questions. The first focuses on practitioners' perceptions of the way that parents think about cultural differences and their relationship to language development in their children. The second concerns the extent to which practitioners consider themselves to have the skills to work with children from other cultures and using different languages. Results/Conclusions: Most countries present a similar profile with intermediate results about their perception of cultural issues, but Lebanon and Turkey are the group with the most positive responses. In terms of bilingual issues most practitioners indicated that they only worked in their country's primary language. The only country where this was not the case was Lebanon. Professionals from Spain and Lebanon form a subgroup in terms of their confidence to work with different cultural/language groups. The paper highlights both the universal importance of cultural and linguistic competence in managing young children's needs and indicates that in most cases professionals do not think they have the necessary expertise to work with cultural and linguistic diversity.

(författare) Towards an Integrated Curriculum in a Speech and Language Pathology Education Programme: Development and Constituents' Initial Responses 2020 Ingår i: Folia phoniatrica et logopaedica : official organ of the International Association of Logopedics and Phoniatrics (IALP). - : S. Karger AG. - 1421-9972. ; 72:1, s. 52-63 Tidskriftsartikel (refereegranskat)abstract <b><i>Background:</i></b> A traditional curricular structure may challenge integration between foundational and clinical sciences in speech and language pathology (SLP) education. This project aimed to increase curriculum integration at a Swedish SLP education programme. <b><i>Methods:</i></b> Learning outcomes in the existent curriculum were copied from their original courses and re-structured with reference to vertical tracks, in order to address them within and across years of study. A content analysis of interviews with teachers and students was conducted for the evaluation of curricular change. <b><i>Results:</i></b> Among the changes were earlier introduction to clinical science and revisiting of foundational sciences later in the education. Theme concepts were defined to scaffold horizontal integration, whereas revisited use of documented material was formalized to ensure vertical integration. In evaluation interviews, multiple examples were provided of how the new curriculum was perceived as being more integrated, with horizontal themes and vertical tracks providing structure. Concerns raised highlight the importance of appointing clear responsibilities. <b><i>Conclusions:</i></b> The concepts “gaps” and “overlaps” may guide remediation of areas where increased curricular integration is warranted. Serial child observations running through the curriculum may provide a platform for both horizontal and vertical integration. For maintenance of curricular integration, clear responsibilities are needed, stretching across course and semester boundaries.
30.	Szabo, Annika, 1972-, et al. (författare) Speaking fundamental frequency and phonation time during work and leisure time in vocally healthy preschool teachers measured with a voice accumulator 2013 Ingår i: Folia Phoniatrica et Logopaedica. - : S. Karger. - 1021-7762 .- 1421-9972. ; 65:2, s. 84-90 Tidskriftsartikel (refereegranskat)abstract OBJECTIVE: More knowledge is needed about preschool teachers' voice use to identify voice behaviours related to work demands that increase the risk for vocal dysfunction. The purpose of this study was to: (1) determine if speaking fundamental frequency (F0) and phonation time differ between work and leisure time and (2) describe variation in F0 and phonation time across the workday in preschool teachers with healthy voices.METHODS: A portable voice accumulator was used to collect data on F0 and phonation time. Twelve vocally healthy female preschool teachers participated in recordings during both work and leisure time for 2 successive days. Their mean age was 35 years (range 21-53 years).RESULTS: Mean F0 was high during the working day (266 Hz) and decreased significantly after work (p < 0.0001). F0 was high also during leisure time (246 Hz) as compared to reference F0 values for Swedish females based on laboratory recordings. Phonation time at work varied widely among the participants, with an average of 12.0%, and decreased significantly to 5.5% during leisure time (p < 0.0001). Most participants had few opportunities for voice rest during work.CONCLUSION: Swedish preschool teachers use high levels of F0 and phonation time during work compared to leisure time indicating high vocal load caused by work. To clarify the role of daily voice use in the causation of vocal dysfunction in this profession, recordings over several days are needed. In addition to F0 and phonation time, recordings of voice sound pressure level and background noise level seem important.
31.	Söderpalm, Ewa, 1953 (författare) Education of speech-language pathologists around the world: The Scandinavian experience 2006 Ingår i: FOLIA PHONIATRICA ET LOGOPAEDICA. - : S. Karger AG. - 1021-7762 .- 1421-9972. ; 58:1, s. 59-63 Tidskriftsartikel (refereegranskat)abstract The object of this paper is to give an overview of the education and training programmes in logopedics offered in the Scandinavian/Nordic countries and to provide some information about the development of the programmes in Scandinavia since their foundation in the 1920s. In order to collect information about the various programmes, a questionnaire comprising 12 questions was sent to representatives for education programmes and national societies affiliated to the IALP. In the past all the countries used to provide possibilities for teachers to continue their education with courses in logopedics to become ‘special teachers’. These programmes no longer exist except in Norway. Degree programmes at bachelor’s and/or master’s level are now offered in all the Nordic countries. It can be concluded that the education and training in logopedics have developed into university degree programmes, with few exceptions, in the Nordic countries.

Karger AG. - 1421-9972. ; 60:4, s. 173-178 Tidskriftsartikel (refereegranskat)abstract <i>Objective:</i> We aimed to assess the equivalence of translations of the Voice Handicap Index (VHI). <i>Patients and Methods:</i> Confirmatory factor analysis was used to assess equivalence of the US version and several translations including (1) Dutch, (2) Flemish Dutch (Belgium), (3) UK English, (4) French, (5) German, (6) Italian, (7) Portuguese and (8) Swedish. VHI questionnaires were gathered from 1,281 subjects. Patients were classified into 11 voice lesion categories. Patients with incomplete response (4%) and patients within voice lesion categories with small numbers were excluded from further analyses, leaving a cohort of 1,052 patients from 8 countries. <i>Results:</i> The internal consistency of the VHI proved to be good. Confirmatory factor analysis across countries revealed that a 3-factor fixed measurement model best fitted the data; the 3 subscales appeared to highly intercorrelated, especially in the US data. The underlying structure of the VHI was also equivalent regarding various voice lesions, but distinct groups were recognized with respect to the height of the VHI scores, indicating that various voice lesions lead to a diversity of voice problems in daily life. <i>Conclusion:</i> The US VHI and the translations appeared to be equivalent, which means that the results from studies from the various included countries can be compared.

(författare) Analysis of the Fundamental Frequency of the Human Voice and Its Frequency Distribution before and after a Voice Training Program 1982 Ingår i: Folia Phoniatrica. - : S. Karger AG. - 0015-5705. ; 34:3, s. 143-149 Tidskriftsartikel (refereegranskat)abstract Three groups of test Ss, 1 with professional voices, 1 with normal, healthy voices, & 1 with more or less pronounced phonastenic voices (N unspecified) took part in an intensive 5-day voice training program. Tape-recordings were made before & after the training period. These tape-recordings were then analyzed with respect to the f spectrum of the voice & the fundamental f & its variation. Single parameter measures are introduced to describe the different changes. Results show that it is possible to replace the subjective evaluations now used with objective measures of the effect of a voice training program

Karger AG. - 1021-7762 .- 1421-9972. ; 61:5, s. 269-274 Tidskriftsartikel (refereegranskat)abstract OBJECTIVE: Motor speech disorders are believed to be uncommon in early Alzheimer's disease (AD). However, data from maximum performance tests of motor speech function in AD and related disorders are virtually nonexistent. The aim of this study was to make such data available. MATERIALS AND METHODS: Sequential speech motion rate was analyzed in 236 memory clinic patients with different levels of cognitive functioning. RESULTS: Sequential speech motion rate was moderately but significantly decreased in mild dementia in AD. About 10% of AD and mild cognitive impairment cases had markedly decreased rates. Rates were strongly reduced in progressive nonfluent aphasia, whereas semantic dementia did not differ from subjective cognitive impairment. Frontotemporal dementia had lower rates than AD. CONCLUSIONS: A proportion of patients with cognitive decline has markedly reduced articulatory agility. The cause of this reduction in some patients with mild cognitive impairment and mild AD is unknown. Semantic dementia is not associated with impaired articulatory agility.
