- Objectives Obstructive sleep apnea (OSA) has an impact on an individual's quality of life and general health, and can also affect their oral health. The patient's experiences, together with intraoral signs and symptoms could indicate the presence of OSA. Knowledge that the patient has, or is at high risk for having OSA can help the dental healthcare provider maintain the oral health and general health for these patients. The purpose was to explore dentists and dental hygienists' experiences when encountering adult patients with potential, untreated and treated OSA. Methods A qualitative inductive approach was used. Experienced dentists and dental hygienists working within Swedish Public Dental Service were strategically selected. Semi-structured face-to-face interviews were performed followed by qualitative content analysis. Results Interviews from 13 participants, seven dental hygienist and six dentists, led to three areas describing varied experience: Importance of the patient encounter and identifying intraoral signs both of which describe experiences related to the importance of the initial unstructured conversation and focused clinical assessments, and strategies for nurturing care which point to interest about care, treatment, and collaborations with medical health care providers. Conclusions Dental professionals are not able to consistently recognize patients who have, or are at high risk for OSA. During the patient encounter, is it important to determine if a patient is at risk for, or has oral signs of OSA.

Gait and postural control after total knee arthroplasty
- 2014
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- The aim of the thesis was to investigate deficits and compensatory strategies after total knee arthroplasty (TKA) in different conditions during gait and quiet standing. Although TKA is considered the gold standard treatment for end-stage knee osteoarthritis, it is associated with a number of implications. Reduced physical function after osteoarthritis is partly, but apparently not fully, remedied by surgery. The two most common deficits are reduced knee muscle strength and limited range of knee joint motion (ROM), partly due to prosthesis mechanics. Reduced postural control has also been shown shortly after surgery. In spite of sufficient passive knee joint ROM for normal ambulation, gait patterns are characterized by reduced knee flexion. Several factors such as reduced knee muscle strength, reduced proprioception, habitual strategies or fear of movement may be suggested as explanations for difficulties in gait and posture. As an effect, compensatory strategies may result. In order to focus on the implications of TKA, participants had to be less than 65 years of age and healthy, TKA being the only factor different form controls. The same 23 individuals with unilateral TKA ~ 19 months post-operative and 23 controls participated in all studies. 3D whole body kinematics was used to assess gait and posture and electromyography was used to record muscle activity. Isokinetic measurements were used to determine dynamic knee muscle strength. Gait in the frontal and sagittal planes were assessed. The tasks included in the test protocol were negotiation up and down stairs, gait on hard and soft surface, quiet standing with sensory modulation (with and without vision and on soft surface), and single limb stance. Primary outcome variables addressed were: knee and hip joint kinematics in frontal and sagittal planes, upper body inclination, postural sway and relative knee muscle activity as an indicator of relative effort. Background factors used to explain group differences in the primary outcomes were derived from demographics, clinical examination, and questionnaires. Demographic factors were age, body mass index (BMI), and time since surgery. Clinical examinations were conducted for passive knee joint ROM, joint position sense, knee muscle strength, anterior knee joint laxity, and leg length. Questionnaires assessed fear of movement, pain, and knee related function and quality of life. The results showed that knee flexion was reduced during stair descent in both the prosthetic and the contralateral knee in the TKA group compared to controls. Although reduced passive knee joint flexion in the TKA group was sufficient for normal stair descent, it was the only factor identified that explained reduced knee flexion in stair descent. As knee muscle strength was significantly reduced in the TKA group, it is reasonable to suggest that as a contributing factor. Furthermore, the TKA group also displayed increased hip adduction during stair descent, which may indicate both a compensatory strategy as well as reduced hip muscle strength. In stair ascent, no significant group differences were found in relative knee muscle activity as expected due to knee muscle weakness. Nor were there any indications of compensatory forward inclination of the trunk to reduce knee joint moments. Instead, probably compensating for muscle weakness, the TKA group ascended stairs at a significantly slower speed. Surface modulation during level gait showed that reduced knee flexion in the prosthetic knee during the stance phase when walking on a hard surface was further decreased during gait on a soft surface. Knee and hip adduction at the stance phase were not affected by surface conditions. Nevertheless, the TKA group displayed increased knee adduction and hip adduction compared to controls, particularly in the prosthetic side. In addition, the TKA group displayed increased step width on the soft compared to hard surface. Single-limb stance for 20 seconds failed in 30 % of the TKA group and in 4 % of the control group. Those in the TKA group who were able to perform single-limb stance performed equally well as controls. During bilateral quiet standing, postural sway was similar in both groups, and inability to stand on one leg did not affect bilateral stance. Older age, higher BMI and reduced quadriceps strength determined the failure to maintain single-limb stance in the TKA group. In conclusion, this thesis indicates that reduced knee muscle strength is a common denominator as part of the explanatory factors for reduced performance and compensatory strategies in individuals with TKA. Reduced speed during stair ascent as well as reduced knee flexion during stair descent may be compensations for reduced lower extremity strength. Increased hip adduction may compensate for reduced knee flexion in stair descent, but may also represent hip muscle weakness or reduced motor control as increased hip adduction is found also in level gait. The failure to maintain single-limb stance in the TKA group is also partly explained by reduced knee muscle strength. Muscle weakness may be and indicator for reduced physical capacity in general.

- Background: Obstructive sleep apnoea syndrome (OSAS) is independently associated with an increased risk for hypertension and cardiovascular disease. Continuous positive airway pressure (CPAP) can reduce mortality and morbidity, but low compliance rates are seen. Aim: To explore and describe the experiences of CPAP-treatment in a young male patient with severe OSAS during a 6-month period from the couples perspective. Methods and the case: A single case study with a phenomenographic approach was employed. Diagnostic procedures of OSAS and initiation of treatment with Auto-CPAP, humidifier and a nasal mask were performed during 4 visits. Conceptions were collected at 4 different occasions during the 6-month period (before, and 2 weeks, 3 months, and 6 months after treatment initiation) by means of interviews with a 33-year old male patient and his female partner. Findings: Totally 17 different structural aspects were found to fluctuate during the 6-month period in relation to; influence of stressors, social reactions and adaptation to increase compliance. Conclusion: An increased knowledge about the influence of stressors, the social reactions, and the adaptation can help healthcare personnel to identify and better understand concerns of other patients and spouses during different time phases of the initial 6-month period of CPAP-treatment.

- Rationale, aims and objectives Continuous positive airway pressure (CPAP) treatment of obstructive sleep apnea (OSA) has a low long-term adherence. Educational interventions are few and sparsely described regarding content, pedagogical approach and participants' perceptions. The aim was to describe adherence to CPAP treatment, knowledge about OSA/CPAP, as well as OSA patients' perceptions of participating in a group-based programme using problem-based learning (PBL) for CPAP initiation.Educational programme The PBL programme incorporated elements from theories and models concerning motivation and habits. Tutorial groups consisting of four to eight patients met at six sessions during 6 months.Methods A sequential explanatory mixed method design was used on 25 strategically selected patients. Quantitative data regarding, clinical variables, OSA severity, CPAP use, and knowledge were collected at baseline, after 2 weeks and 6 months. Qualitative data regarding patients' perceptions of participation were collected after 6 months by semi-structured interviews using a phenomenographic approach.Results 72% of the patients were adherent to CPAP treatment after 2 weeks and 6 months. All patients improved their baseline knowledge about OSA and CPAP after 2 weeks and sustained it after 6 months. Anxiety and fear, as well as difficulties and needs were motivational factors for participation. Patients described the difficulties of behavioural change, an awareness that improvements do not occur immediately, a realization of the importance of both technical and emotional support and the need for a healthier lifestyle.Conclusion and practice implications A group-based programme using PBL seems to facilitate adaptive and developmental learning and result in acceptable CPAP adherence levels.

- Continuous positive airway pressure (CPAP) is the treatment of choice for obstructive sleep apnoea syndrome (OSAS), but side effects are common and long-term adherence low. The Type D (distressed) personality is defined as a combination of negative affectivity and social inhibition. The association of Type D personality with adherence has not been studied in CPAP-treated patients with OSAS. This study aimed to describe the prevalence of Type D personality in OSAS patients with CPAP treatment longer than 6 months and the association with self-reported side effects and adherence. A cross-sectional descriptive design was used. A total of 247 OSAS patients with a mean use of CPAP treatment for 55 months (6-182 months) were included. Data collection was achieved by two questionnaires; the Type D scale 14 (DS14) (Type D personality), SECI (side effects of CPAP), as well as from medical records (clinical variables and objective adherence to CPAP treatment). Type D personality occurred in 30% of the patients with OSAS and significantly (P < 0.05-0.001) increased the perceived frequency and severity of a broad range of side effects. The objective adherence was significantly lower (P < 0.001) for OSAS patients with Type D compared to OSAS patients without Type D, both with regard to a mean use of 4 h per night and 85% of the self-rated sleep time per night. The additional effect of a Type D personality on perceived side effects and adherence to CPAP treatment found in this study could be used by healthcare personnel when evaluating patients waiting for treatment.
