- Objective: To examine the construct and rating scale of the Assessment of Capacity for Myoelectric Control, an assessment to evaluate ability in using a prosthetic hand.Design: Cross-sectional study. Subjects: Upper limb prosthesis users with different prosthetic levels/sides and prosthetic experience were included (n=96).Methods: Subjects' assessments with the Assessment of Capacity for Myoelectric Control were collected by 6 raters during their regular hospital visits. Rasch analysis was used, since it allowed an analysis of the data at the item and category levels. Dimension, item hierarchy and item fit statistics were used to examine the construct. Different Rasch parameters were used to examine rating scale structure and its use.Results: The consistency of item difficulties with clinical knowledge and the unidimensionality confirmed that the construct is valid. Two items functioned unexpectedly (misfit), but the misfit was idiosyncratic to the sample, not systematic to the items. The 4-point rating scale usefully differentiated the subjects on the basis of their abilities. The use of category 2 was somewhat redundant.Conclusion: The Assessment of Capacity for Myoelectric Control is a valid assessment that evaluates ability in using a prosthetic hand. Revision of the category 2 definition would improve the functioning of the rating scale.

- BACKGROUND:Foot pain decreases individuals' ability to perform daily activities. Insoles are often prescribed to reduce the pain which, in turn, may promote return to normal activities.OBJECTIVES:To evaluate the effects of insoles on foot pain and daily activities, and to investigate the relationship between individuals' satisfaction with insoles and actual use of them.STUDY DESIGN:A 4-week pre-post intervention follow-up.METHODS:Brief Pain Inventory, International Physical Activity Questionnaire and Lower Extremities Functional Status were used as outcome measures. Client Satisfaction with Device was used in the follow-up.RESULTS:A total of 67 participants answered the questionnaires (81% women). Overall, a reduction in Pain Severity (p = 0.002) and Pain Interference (p = 0.008) was shown. Secondary analyses revealed a significant effect only in women. No changes in daily activities (Walking, p = 0.867; Total Physical Activity, p = 0.842; Lower Extremities Functional Status, p = 0.939) could be seen. There was no relation between Client Satisfaction with Device measures and duration of insole use. A difference in sex was shown; women scored higher than men on Pain Severity.CONCLUSION:Insoles reduce pain and pain interference with daily activities for women with foot pain. Satisfaction with the insoles is not a predictor of actual insole use. The effect of insoles on activity performance needs further study.CLINICAL RELEVANCE:This study provides evidence for prescribing insoles to people with foot pain. Nonetheless, insoles are not enough to increase their physical activity level in the short term. Satisfaction with insoles and duration of use are not correlated and cannot be inferred from each other.

- Research concerning the significance of assistive technology to spouses of persons who uses technology is sparse and the impact of a powered wheelchair on spouses' activity and participation is not at all researched. Thus, the aim was to explore how spouses experience the significance of a powered wheelchair prescribed to and used by their next of kin. A descriptive design with a qualitative approach focusing on the experiences of the spouses was used. The sample comprised of 10 spouses of elderly people that have been prescribed a powered wheelchair. Semi-structured interviews were conducted with the ten spouses (nine women and one man). The participants were 65-86 years of age. The questions posed during the interview concerned: i) the significance of the powered scooter for personal everyday activities, participation and quality of life; ii) the significance of the scooter for shared activity and participation; and iii) the significance of the next of kin using a scooter, from the perspective of the spouse. Interviews were transcribed verbatim and analyzed using qualitative content analysis. The results showed that the spouses experienced that their everyday life and life situation had changed in a positive way as their next of kin received a powered wheelchair. They experienced a sense of freedom that had an impact on their own activities as well as on the activities they performed together with their next of kin. The spouses expressed that they now to a larger extent shared responsibility for different tasks in the home and also how the powered wheelchair had made it possible to spontaneously do things together again and to do things with more ease. In conclusion, the narratives of the spouses of the elderly powered wheelchair users were to a great extent positive. The powered wheelchair was of great value and brought freedom to everyday life.

Konferensbidrag (refereegranskat)abstract
- Since 1978, the Limb Deficiency and Arm Prosthetic Centre (LDAPC) at Örebro University Hospital in Sweden offers a 5-day training camp for paediatric myoelectric prosthesis users1. The aim of the camp is to support the establishment of a regular prosthesis wearing pattern, increase capacity for control of the device, and establish prosthesis use in everyday tasks. Every year in August paediatric myoelectric hand users and their parents are invited to attend this intensive training. The camp consists of around 8 hours of scheduled training each day, both in everyday tasks and outdoor play activities. A structured programme with training of fine motor skills in the mornings and gross motor skills later in the days is prepared by the occupational therapists. The aim was to evaluate the effectiveness of this training procedure on children’s ability to operate the myoelectric hand.During 8-13 August, 2010, 11 children (aged 6-9, 6 boys) with unilateral below-elbow deficiency participated in the camp. The Assessment of Capacity for Myoelectric Control (ACMC)2 was used to evaluate the effectiveness of intensive training on ability to operate the hand. Every child performed an ACMC activity on the first and the last day of the camp (packing suitcase). Their performances were videotaped and scored by an ACMC rater that did not take part in training of the participants at the camp. An ability score for each child was calibrated by Winsteps program. The average ability scores changed from 2.45 logits to 5.04 logits. Most of the children (n=8) had a big change in the ACMC items that measure timing in grasping and releasing objects. The Conclusion is that the training camp is effective in improving the children’s ability to operate a myoelectric hand. The long-term effects on wearing time, skill and bimanual performance from intensive training camps need further studies.

Konferensbidrag (refereegranskat)abstract
- Introduction: The Assessment of Capacity for Myoelectric Control (ACMC) is an observation-based tool that evaluates ability to control a myoelectric prosthetic hand [1]. Validity evidence led to ACMC version 2.0, but test - retest reliability and minimal detectable change (MDC) of ACMC have never been evaluated. For instruments that have an evaluative purpose, such as ACMC, the MDC is a useful clinical value to suggest whether a change is due to measurement error or true change. Investigation of rater agreements in this version was also needed because it has new definitions in certain rating categories and items.Methods: Upper limb prosthesis users (n=25, 13/12 male/female, 15/10 congenital/acquired; mean age 27.5, range 7-72, years) performed one standardized activity twice, 2–5 weeks apart. Activity performances were video-recorded and assessed by two ACMC raters. The item raw scores were converted to Rasch interval ability measures. Ordinal data were analyzed by weighted κ; interval data were analyzed by intraclass correlation coefficient (ICC) and Bland–Altman limit of agreement (LOA) method.Results: For test–retest reliability, ICC2,1 was 0.94. Average weighted κ was 0.76 and percentage agreement (PA) was 85%. In individual items, weighted κ agreements were fair to excellent (0.52・1.00) and PAs were ≥6・100%. MDC95 was ≤.55 logits (1 rater) and 0.69 logits (2 raters). All MDC95 values were ≤5% of the total ability logit range. In the Bland-Altman plot the upper and lower LOA were 0.86 and -0.88 respectively. All except one participant were within the 95% LOA. For inter-rater reliability, weighted κ agreements were fair to excellent in both sessions (0.44–1.00), and ICC2,1 was 0.95 (test) and 0.92 (retest). Intra-rater agreement (rater 1) was excellent (ICC3,1 0.98). The weighted κ values of the test session were all >0.80 and the PAs for each item were ≥6%.Conclusion: The results of the present study demonstrate different aspects of the reliability of ACMC 2.0. Based on these results, we can recommend ACMC as a tool to follow the progress of users in controlling their myoelectric prostheses. The MDC is clinically useful for ACMC raters as a guideline when following the client’s changes over time.

Tidskriftsartikel (refereegranskat)abstract
- Objectives: To investigate the cross-cultural validity of the Orthotics and Prosthetics Users’ Survey (OPUS), to evaluate differential item functioning (DIF) related to country, sex, age, amputation level, and amputated side (unilateral, bilateral), and to determine known-group validity of the OPUS.Design: Survey.Setting: Outpatient clinics.Participants: The sample (NZ321) consisted of Swedish (nZ195) and U.S. (nZ126) adults using lower-limb prostheses.Interventions: Not applicable.Main Outcome Measures: Four OPUS modules were used: lower extremity functional status, client satisfaction with device (CSD), client satisfaction with services (CSS), and health-related quality of life. Rasch analysis was used to calculate measures for persons and items.Results: The cross-cultural validity was satisfactory. Many items demonstrated DIF related to country and demographic characteristics, but the impact on mean person measures was negligible. The rating scales of CSD and CSS needed adjustments, and the unidimensionality of CSD and CSS was weak. The differences between the mean measures of known patient groups were statistically significant for 2 out of 6 comparisons.Conclusions: This study supports the validity of OPUS measure comparisons between Sweden and the United States and between subgroups with different demographic characteristics. Some of the country-related DIF may reflect the different health care financing systems. The findings demonstrate that the OPUS can discriminate between certain patient groups. The results also challenge some of our preconceptions about persons with bilateral amputation, indicating that we might know these persons less well than we think.

Tidskriftsartikel (refereegranskat)abstract
- Purpose: To evaluate the validity of a modified version of the Orthotics and Prosthetics Users' Survey (OPUS) with persons using different prosthetic and orthotic (P&O) devices.Method: Two-hundred-and-eighty-two adults using prosthesis, orthosis, shoe insoles or orthopaedic shoes completed OPUS. OPUS comprises five modules - Lower and Upper Extremity Functional Status, respectively (LEFS and UEFS), Client Satisfaction with Device and Services, respectively (CSD and CSS), and, Health-Related Quality of Life (HRQoL). Eight new items were added to LEFS and six to UEFS. Rasch analysis was used for data analyses.Results: Rating scales functioned satisfactory after some modifications. All modules demonstrated a ceiling effect. Unidimensionality was satisfactory after deleting some items and dividing HRQoL into two subscales, although somewhat weak on CSD and CSS. Item reliability was excellent for all modules and person reliability good for all but CSD and CSS. Some items demonstrated differential item functioning related to sex and age, but the impact on person measures was small.Conclusions: This study supports the validity of a modified version of OPUS for persons using different P&O devices, but also reveals limitations to be addressed in future studies. OPUS could be useful in clinical rehabilitation and research to evaluate P&O outcomes.

Tidskriftsartikel (refereegranskat)abstract
- The Assessment of Capacity for Myoelectric Control (ACMC) is an observation-based clinical tool that evaluates ability to control a myoelectric prosthetic hand during bimanual activities. Two validity aspects were investigated: potential bias interaction between prosthesis users and activities performed during assessment, and potential bias interaction between activities and different user characteristics (sex or prosthetic side). Six activities were standardized for the ACMC. Upper-limb myoelectric prosthesis users (47 congenital, 11 acquired; 31 male, 27 female, average age 19.9 yr) performed three standardized activities, each on one occasion. Bias-interaction analysis in the many-facet Rasch model identified inconsistent patterns in the interactions of individual users and activity facets and between activities and user characteristics. The standardized activities had no significant influence on measures of user ability. The activities functioned similarly across both sexes (p-value greater than or equal to 0.12) and across both prosthetic sides in persons with upper-limb reduction deficiency (p-value greater than or equal to 0.50) and persons with acquired amputation (p-value greater than or equal to 0.13). The results provide evidence for the validity of the ACMC across the standardized activities and support use of the ACMC in prosthesis users of both sexes and prosthetic sides. The newly standardized activities are recommended for future ACMC use.

Konferensbidrag (refereegranskat)abstract
- Introduction: The Assessment of Capacity for Myoelectric Control (ACMC) is an observational based instrument that evaluates the ability to operate a myoelectric prosthetic hand. It is performed during the execution of bimanual tasks chosen by the clients. Although the ACMC does not assess task performance, it is unknown whether the clients’ ability measures are influenced by factors such as task complexity. The study aim was therefore to develop standardized tasks and to examine whether (i) the clients’ ability measures are influenced by the tasks (ii) the tasks function the same across different client characteristics based on age, sex, prosthetic side and experience.Method: Six tasks were chosen from ACMC raters’ suggestions and standardized for the ACMC. Myoelectric prosthesis users (n=58, mean age=20, 31 males) were recruited from the Örebro University Hospital, Sweden. Each user performed 3 tasks. All task performances were videotaped and rated on the 22 ACMC items according to a 4-point capability scale.Many-facets Rasch analysis was used to (i) examine whether the three ability measures of each user were significantly different from each other, and (ii) to reveal if a particular client characteristics was scored differently in a particular task.Result: No significant difference in the ability measures was found in the majority of the sample – only three sporadic users were significantly different in one or two of their tasks. This implies that the client’s ability measures are not influenced by the tasks. No significant difference was found related to prosthetic side and experience. Minor difference was found in sexes and two age groups (age 7 to 15, over 15) but the differences were too small to be clinically relevant.Conclusions: This study provides further validity evidence of the ACMC. Research with more challenging tasks is needed to confirm the findings.

Validity evidence led to ACMC version 2.0, but the test-retest reliability and minimal detectable change (MDC) of the ACMC have never been evaluated. Investigation of rater agreements in this version was also needed because it has new definitions in certain rating categories and items. Upper-limb prosthesis users (n = 25, 15 congenital, 10 acquired; mean age 27.5 yr) performed one standardized activity twice, 2 to 5 wk apart. Activity performances were video-recorded and assessed by two ACMC raters. Data were analyzed by weighted kappa, intraclass correlation coefficient (ICC), and Bland-Altman method. For test-retest reliability, weighted kappa agreements were fair to excellent (0.52 to 1.00), ICC2,1 was 0.94, and one user was located outside the limits of agreement in the Bland-Altman plot. MDC95 was less than or equal to 0.55 logits (1 rater) and 0.69 logits (2 raters). For interrater reliability, weighted kappa agreements were fair to excellent in both sessions (0.44 to 1.00), and ICC2,1 was 0.95 (test) and 0.92 (retest). Intrarater agreement (rater 1) was also excellent (ICC3,1 0.98). Evidence regarding the reliability of the ACMC is satisfactory and MDC95 can be used to indicate change.

Upper limb prosthetic outcome measures : Review and content comparison based on International Classification of Functioning, Disability and Health
- 2010
-
Ingår i: Prosthetics and Orthotics International. - : Ovid Technologies (Wolters Kluwer Health). - 0309-3646 .- 1746-1553. ; 34:2, s. 109-128
-
Forskningsöversikt (refereegranskat)abstract
- The International Classification of Functioning, Disability and Health (ICF) has been recommended as a framework for evaluation of aspects of health. The aim of this study was to compare the contents of outcome measures for upper limb prosthesis users by using the ICF. Measurement focus and psychometric properties of these measures were also investigated. Outcome measures that used upper limb prosthesis users as subjects in their development and psychometric evaluations were selected. The psychometric studies (n - 14) were reviewed and scored and the items in the measures were linked to the ICF. One measure for all ages (ACMC), five paediatric measures (CAPP-FSI, CAPP-PSI, PUFI, UBET and UNB) and two adult measures (OPUS and TAPES) were selected. The concepts extracted (n - 393) were linked to 54 categories in the ICF. The ACMC, CAPP-FSI, UBET, UNB and PUFI measure categories mostly under the ICF component 'Activity and participation'. The TAPES and OPUS also measure ICF categories that describe the emotional and social status of a person. The main conclusion is that the use of a mixture of outcome measures would give a better picture on the aspects of our clients. Measures that focus on the social interaction in paediatric users are required.

Effekten av en eldriven rullstol (scooter) för äldre personer
- 2015
-
Konferensbidrag (refereegranskat)abstract
- Bakgrund: Att kunna förflytta sig är ofta en förutsättning för att kunna delta i olika aktiviteter, en eldriven rullstol kan bidra till detta.Syfte: Syftet var att undersöka effekten av en eldriven rullstol på äldre personers aktivitet, delaktighet och livskvalitet.Metod: Personer > 65 år som för första gången remitterats till Centrum för hjälpmedel; ÖLL, för utprovning av eldriven rullstol för utomhusbruk inkluderades konsekutivt. Mätning gjordes före förskrivning och efter 4 månaders användning av eldriven rullstol med olika instrument för aktivitet, delaktighet (Individually Prioritized Problem Assessment, IPPA och WHO-Disability Assessment Schedule, WHODAS 2.0) och hälsorelaterad livskvalitet (SF-36). Analyser genomfördes med t-test. Cohens d användes för beräkning av effektstorlek. För att klassificera deltagarnas självskattade aktivitetsproblem (IPPA) användes Klassifikation av funktionstillstånd, funktionshinder och hälsa (ICF).Resultat/preliminärt resultat: Fyrtiofem personer (m=78 år, 36 män, 9 kvinnor inkluderades, samtliga fick en trehjulig eldriven rullstol med manuell styrning förskriven (scooter). För hela gruppen visade resultatet en statistisk signifikant förbättring med stor effekt av scootern på personernas aktivitetsproblem (IPPA; n=164). Majoriteten av problem var inom områdena Hemliv (i huvudsak olika inköp) och Samhällsgemenskap, socialt och medborgerligt liv (rekreation och fritidsaktiviteter): För hela gruppen framkom små signifikanta förbättringar inom WHODAS 2.0 domän Delaktighet och inom SF-36 index Fysisk hälsa och delskala Fysiska roller. Vid subgruppsanalyser framkom medelstora signifikanta förbättringar för kvinnor inom domänen Delaktighet (WHODAS 2.0) och för män små förbättringar inom delskalorna Fysiska roller och Social funktion (SF-36).Slutsats: En eldriven scooter har ett stort positivt värde för äldre personers egna prioriterade aktiviteter och en liten effekt på hälsorelaterad livskvalitet.

- Purpose: The aim was to explore the effect of using a powered mobility device (PMD) on older peoples’ activity, participation and quality of life (QoL).Method: A pre- and post-intervention design with outcome measures for activity, participation (Individually Prioritized Problem Assessment, IPPA; World Health Organization Disability Assessment Schedule, WHODAS 2.0) and QoL (SF-36) were used. T-test was used to analyse the data. The magnitude of the effects was measured by Cohen’s criteria for effect sizes (d).Results: The sample consisted of 45 individuals (36 men) aged 66–88 years referred for prescription of a PMD. All were prescribed a powered scooter (PS). A statistically significant improvement with a large effect on IPPA in the ICF domains of Self-care (d¼2.47), Domestic life (d¼2.40), Interpersonal interactions and relationships (d¼2.08), and Community, social, and civic life (d¼2.36) was found. Medium-sized improvement on the WHODAS 2.0 domain of Participation and small improvements in the SF-36 domains of Physical Health and Role-Physical were also found.Conclusion: A PS has significant effects on the areas of activity, participation and QoL in elderly people. These findings have implications for prescriptions of a PS to this population.

Konferensbidrag (refereegranskat)abstract
- Objectives: (1) To compare the prevalence of self-reported musculoskeletal complaints (MSC) in individuals with major upper limb defects (ULD) in the Netherlands with a control group, (2) to explore the influence of MSC on health status and work and (3) to assess predictors of MSC, disability and work productivity in ULD.Methods: A national survey among individuals with ULD and controls was performed, using the databases of rehabilitaA national survey among individuals with ULD and controls was performed, using the databases of rehabilitation centers and orthopedic workshops in the Netherlands. A questionnaire was designed based on known risk factors for MSC, and it included validated (subscales of) existing questionnaires, such as SF36 and the Pain Disability Index (PDI). Inclusion criteria were ≥ 18 years and major ULD at or proximal to the carpal level. Controls were recruited by convenience and matched on age and sex.Results: Of the 263 individuals with ULD that completed the questionnaire, 42% had a congenital transversal defect and 58% had an amputation. The mean age was 50.7±16.7 years and 60% was male. A prosthesis was used by 79%. In total 108 controls were included (mean age 50.6±15.7; 65% male). Year prevalence of MSC (lasting for at least four consecutive weeks) was 65% in individuals with ULD, compared to 34% in controls. The most common location of MSC was the dominant or non-affected limb (46% in patients and 17% in controls), followed by upper back/neck (43% in patients and 19% in controls). Presence of MSC was associated with lower scores on scales of general health perception, mental health, work productivity and higher scores on disability. Prosthesis use did not differ between individuals with and without MSC. Predictors for presence of MSC were deficiency of the right limb, higher upper extremity work demands and being divorced or widowed. More pain, lower mental health and higher age were associated with a more severe disability. Predictors for lower work productivity were presence of MSC and more pain.Discussion: Presence of MSC is a common problem in individuals with ULD. Mostly affected were the non-affected limb and upper back/neck. More research on employment of the affected and non-affected limb, and its relation with MSC, is therefore warranted. Interestingly, presence of MSC was not related to prosthesis use. Associations with disability and work productivity add extra relevance to the study results, because of its relevance for individuals and society.Conclusion: Prevention and treatment of MSC deserves an important role in rehabilitation medicine of individuals with ULD.

- Objective: to analyze work participation, work productivity and contributing factors, as well as physical work demands, in individuals with an upper limb defect (ULD).Design: cross-sectional study: postal survey (response rate: 53%).Setting: patients of twelve rehabilitation centers and orthopedic workshops in the Netherlands.Participants: 207 individuals with unilateral transversal upper limb reduction deficiency (ULRD) or amputation (ULA), at or proximal to the carpal level, between the ages of 18 and 65 years, and a convenience sample of 90 controls (matched on age and gender).Interventions: not applicable.Main outcome measures: employment status, self-reported work productivity and self-reported upper extremity work demands.Results: 74% of individuals with ULRD and 57% of the individuals with ULA were employed. Males, using a prosthesis, with medium or higher level of education and good general health were most often employed. Work productivity was similar to the control group. Higher work productivity was related to predominantly mentally demanding type of work and less MSC related pain. Upper extremity work demands were higher in individuals with ULD with predominantly mentally demanding work, compared to controls with this type of work. Conclusions: the outcome of work participation of individuals with ULRD is comparable to the general population in the Netherlands. Individuals with ULA had lower rates of employment. Work productivity was not associated to one-handedness.

Translation and linguistic validation of self-administered Swedish version of WHODAS 2.0
- 2015
-
Konferensbidrag (refereegranskat)abstract
- Background: Use of Patient-Reported Outcomes (PROs) is increasingly requested in clinical practice and research. The World Health Organization Disability Assessment Schedule 2.0 (WHODAS 2.0) is a generic instrument for self-report capturing functioning in the life-domains of understanding and communicating, getting around, self-care, getting along with people, life activities and participation in society. It is based on the same conceptual foundation as the International Classification of Functioning Disability and Health (ICF). Several language versions of WHODAS 2.0 are available and a Swedish version is in progress.Aim: To translate the self-administered 36-item version of WHODAS 2.0 into Swedish and examine the understanding and interpretation of the instruments´ content and response processes.Methods: Translation process was made following WHO guidelines and the WHODAS 2.0 translation package (version 1.0) including: forward-translation, expert panel discussion, back-translation, pre-test of preliminary version, final version, and pilot-testing of the final version.Pre-test was conducted through structured interviews in purposeful samples of Swedish-speaking adults including two patients with bi-polar disorder and a sample from the general population. Pilot-testing of the final version will be performed by structured interviews in a purposeful sample of outpatients.Results: Forward-translation, expert panel discussion, and back-translation resulted in a preliminary Swedish version of WHODAS 2.0. Pre-test revealed some issues related to items in the Participation in society domain, and in the overall lay-out. This resulted in minor changes in selection of words in the final version and suggestions for future revision of the instrument.Pilot-testing of the final version in outpatients are under progress and the result will be ready to present before Conference date in November 2015.Conclusion: The preliminary Swedish self-administered version of WHODAS 2.0 is easy to understand and respond to. Further studies are needed to provide evidence for validity of the final Swedish WHODAS 2.0.

- Introduction: Today there is an increasing awareness of the need for validated instruments in upper limb prosthetics outcome assessments. One of the instruments suggested is the Southampton Hand Assessment Procedure (SHAP). In order for the clinicians to know how to interpret the results from the assessments, norms for different age groups are needed. Previously, normative data for SHAP has been reported for an English sample and work is underway from Slovenia. However, norms are only available for people up to 75 years of age, and no normative data is available for Sweden. Hence, the aim was to collect data also from people age 75 and older, and from Sweden.Methods: Participants and procedure — 58 persons (md age 52.5, range 20-92 years) participated in the study. Participants were recruited among students at Örebro University, staff at Örebro University Hospital, and people attending a community-based centre for senior citizens. Inclusion criteria were self-determined normal hand-function and no hand-impairment at time of testing. Data was collected according to the standardized procedure in the manual, and by one single "assessor" an OT-student. Instrumentation — The SHAPconsists of 26 tasks: 6 abstract objects in both lightweight and heavyweight form, and 14 simulated ADL-tasks. All tasks are representing one out of six grip-patterns. The subject is instructed to start and stop the timer before and after performing the task. An overall score, the Index of Functionality (IOF), is calculated based on the resulting times.Results: Mean IOF was 96.7. One-way ANOVA with index of functionality as dependent variable showed a statistical significant difference in dominant hand function between age groups.

- A need for a systematic measurement of function for upper limb prosthetics has been identified. Using the World Health Organization-International Classification of Functioning, Disability and Health (WHO-ICF) model, it was clear that no single test was able to cover the entire cycle of prosthetic use from research to application in the field, but it was believed that a unified approach throughout the profession would allow better communication between the contributors to this process. Through a series of meetings, such an approach has been formulated and a special interest group formed that aims to analyze the current literature on the subject, and identify which tools already in existence have the psychometric properties that allow for valid comparison of data between centers and countries. After this analysis, recommendations for a toolkit of different validated tools will be made, along with identifying any gaps within the kit that need additional attention.

- Rapid improvements in materials, design, and treatment in upper limb prosthetics makes assessment an important area. After meetings at international conferences and workshops, a special interest group of professionals concerned with the provision of upper limb prostheses was formed to create a systematic approach to measurement of function for upper limb prostheses. They used the World Health Organization's International Classification of Functioning, Disability and Health (ICF) model to identify a series of tests that could cover the cycle of prosthetic use from research to application in the field. It is suggested that a unified approach throughout the profession would allow better communication between the respective groups. The group analyzed literature on the subject and identified which existing tools have the psychometric properties that allow for valid comparison of data between practitioners. The group proposes that a toolkit of different validated measures has been identified, along with gaps within the kit that need additional attention.

Cross-cultural validity and differential item functioning of theOrthotics and Prosthetics Users’ Survey with Swedish and Americanusers of lower limb prosthesis
-
Annan publikation (övrigt vetenskapligt/konstnärligt)abstract
- Objective: To investigate the cross-cultural validity of the Orthotics and Prosthetics Users’ Survey (OPUS), to investigate differential item functioning (DIF) in the OPUS related to sex, age, amputation level and amputated sides (unilateral or bilateral), and to determine the known-group validity of the OPUS.Design: Cross-sectional study design.Setting: 2 outpatient clinics in Sweden and 7 outpatient clinics in the United States.Participants: A total of 195 Swedish and 126 American adults using lower limb prosthesis.Interventions: Not applicable.Main Outcome Measure: 4 modules from the OPUS were used in this study, including the Lower extremity functional status (LEFS), Client satisfaction with device (CSD), Client satisfaction with services (CSS), and Health-related quality of life (HRQoL) modules. Items were scored on 4- or 5-level Likert scales, and a Rasch measure was calculated for each person and module.Results: The cross-cultural validity was satisfactory. Many items demonstrated DIF related to country and demographic characteristics, but the impact on mean person measures was negligible. The rating scales of the CSD and CSS needed adjustments, and the unidimensionality of the CSD and CSS was weak. The differences between the mean measures of known patient groups were statistically significant for age in the LEFS and for the level of amputation in the CSD.Conclusions: This study supports the validity of comparing OPUS measures between Sweden and USA and between patient groups with different demographic characteristics. The OPUS can, to some extent, discriminate between patient groups known to be different. The unidimensionality of the CSD and CSS modules is weaker than the other modules and these need further development and evaluation.

Tidskriftsartikel (refereegranskat)abstract
- Background: The Orthotics and Prosthetics Users' Survey consists of five modules to assess outcomes of orthotic and prosthetic interventions: lower extremity functional status, upper extremity functional status, client satisfaction with device, client satisfaction with services and health-related quality of life.Objectives: To investigate the test-retest reliability and calculate the smallest detectable difference for all modules of the Swedish Orthotics and Prosthetics Users' Survey.Study design: Test-retest reliability study design.Methods: A total of 69 patients at a Department of Prosthetics and Orthotics completed Orthotics and Prosthetics Users' Survey on two occasions separated by a 2-week interval, giving 18 answers on lower extremity functional status, 41 on upper extremity functional status, 53 on client satisfaction with device, 12 on client satisfaction with services and 67 answers on health-related quality of life. Raw scores were converted into Orthotics and Prosthetics Users' Survey units on a 0-100 scale. Intra-class correlation coefficients, Bland-Altman plots, common person linking plots and t-tests of person mean measures were used to investigate the reliability. The 95% confidence level smallest detectable differences were calculated.Results: The intra-class correlation coefficients ranged from 0.77 to 0.96 for the modules, and no systematic differences were detected between the response occasions. The smallest detectable differences ranged from 7.4 to 16.6 units.Conclusions: The test-retest reliability was satisfactory for all Orthotics and Prosthetics Users' Survey modules. The smallest detectable difference was large on all modules except the health-related quality of life module.Clinical relevance: The Orthotics and Prosthetics Users' Survey modules are reliable and, thus, can be recommended for repeated measurements of patients over time. Relatively large changes are needed to achieve statistical significance when assessing individual patients.

Bokkapitel (övrigt vetenskapligt/konstnärligt)abstract
- Assessment tools are vital in measuring the outcomes of any practice or procedure. In the development and use of a prosthetic limb, this can be divided into three areas; the basic functions of the design, activities the limb is used for, and the amount the user actually employs the hand in everyday life. Each area is distinct and different and it needs different tools designed specifically for each area in order to reliably measure these outcomes. The development of these tools must include means to make sure the tool measures what the tester thinks it measures and makes sure that such measurements are consistent across time and between testers. Once a consistent set of tools is developed it allows clinicians to discuss and compare devices, training methods and solutions. It also allows investigation of different designs.Currently, the emphasis is on the basic practical measurements of function, activity and participation. This uses simple methods based on observation, timing or questionnaires to measure the use of simple prostheses. With newer designs of multifunction hands and microprocessor controllers being introduced, there are more varied control methods for the different hands. This requires more sophisticated methods to measure the impact of the new designs. These new methods include the measurement of the motions of the body and upper limbs with optical methods, and looking at measuring the cognitive load that controlling such hands impose on the user. To allow simple comparisons between users, the tasks and methods have to be constrained. This creates more artificial activities which may themselves be too artificial to tell the observer what they need to know, so the choice of activity is a balance between realistic tasks and reliable results.

- AIM: The purpose of this study was to describe experiences of everyday activities and social support in daily life in children with disabilities.METHOD: Interviews were conducted with 33 children (14 girls and 19 boys, aged 7-13 years) with physical, intellectual, or neuro-psychiatric disability. Interviews were analysed using qualitative content analysis.RESULTS: In many ways, the children described themselves as being like any other child or adolescent. Their narratives showed that they had developed strategies to cope with the consequences of their disability, both socially and in the performance of daily activities. The children received social support in everyday activities, mainly from their family and close friends. Meeting other children with the same disability supported opportunities for identification. However, their experiences of everyday activities were in many cases associated with sadness, especially when they could not participate in activities with their peers.CONCLUSIONS: According to the children's statements, it is important for people close to these children, both habilitation staff and others, to take responsibility for improving emotional, informative, and instrumental support in order to enable the children to perform and participate in everyday activities.

Tidskriftsartikel (refereegranskat)abstract
- Objective: To describe upper body structures associated with upper limb reduction deficiency and the development of these structures over time, to examine the presence of physical complaints in this population, and to compare body structures and complaints between groups based on prosthesis use.Design: Prospective cohort study with a follow-up period of 24 years, with matched able-bodied controls.Subjects: Twenty-eight patients with unilateral below-elbow reduction deficiency fitted with myoelectric prostheses, aged 8-18 years at inclusion.Method: Measurements of upper arm, trunk and spine were performed and study-specific questionnaires were answered at baseline and follow-up; the Brief Pain Inventory and the Quick Disability of Arm, Shoulder, and Hand questionnaires were answered at follow-up.Results: Both at baseline and follow-up, within-subjects differences in structures of the arm and trunk were shown in patients but not in controls. Spinal deviations, although small, were greater in patients compared to controls. Self-reported disability was higher in patients compared to controls. Differences in back pain and effect of prostheses use could not be shown.Conclusions: Patients with unilateral below-elbow reduction deficiency have consistent differences in upper body structures. Deviations of the spine, probably of functional origin, do not progress to clinically relevant scoliosis.

Konferensbidrag (refereegranskat)abstract
- Introduction: In children with upper limb reduction deficiency (ULRD) scoliosis has been reported but the development of these spinal deviations over time is unclear. Furthermore, little is known about the development of other upper body structures and potential physical complaints in this population. Also, the influence of prosthesis use on the development of body structures or complaints is unknown.Aim: To describe upper body structures of persons with unilateral ULRD and the development of these structures over time, to examine the presence of physical complaints in this population, and to study the effect of prosthetic use on body structures and physical complaints.Method: A prospective cohort study with a follow-up period of 24 years was conducted. Twenty-eight persons (age 8-18 years at inclusion) with ULRD and 62 matched controls underwent measurements of upper-arm, trunk and spine and answered study-specific questionnaires at baseline and follow-up. In addition, at follow-up the Brief Pain Inventory and the Quick Disability of Arm, Shoulder and Hand questionnaires were answered.Results: Within-subject differences in structures of the arm and trunk were shown in patients but not in controls both at baseline and follow-up. Spinal deviations were greater in patients compared to controls. No structural scoliosis was found. Self-reported disability was higher in patients compared to controls. Differences in back pain and effects of prosthesis use could not be detected.Discussion: The structural within-person difference between body-halves may explain the findings of spinal deviations. The rates of physical complaints were remarkably low, compared to other studies. This might be due to differences between persons with ULRD and acquired upper limb amputations, level of deficiency, prosthetic use or age.Conclusions: Persons with ULRD have consistent differences in upper body structures over time. Deviations of the spine, probably of functional origin, do not proceed to clinically relevant scoliosis.
