Experiences with using a pushrim-activated power-assisted wheelchair for community-based occupations: a qualitative exploration.

BACKGROUND: Occupational therapists strive to engage individuals in occupation and enhance community access through wheelchair prescription. Previous research with pushrim-activated, power-assisted wheelchairs identifies a reduction in the physical demands of manual wheelchair propulsion but limited evidence exists regarding user evaluation in context. PURPOSE: This study explored the experience of using a power-assisted wheelchair in the community. METHODS: Eight individuals who used both a power and manual device participated in focus groups after trialing a power-assist wheelchair for three weeks. Data were analyzed using a qualitative description approach. FINDINGS: Three themes emerged from our analysis: relative advantages and disadvantages; environmental factors that affect accessibility; and evaluation of mobility device. IMPLICATIONS: Participants perceived the power-assist as improving performance and accessibility compared with the manual wheelchair, increasing the potential scope of occupations and environments, but not replacing their power mobility device. Sufficient time for adjustment of both user and device was important.

Effectiveness of an ergonomic keyboard for typists with work related upper extremity disorders: a follow-up study.

OBJECTIVE: To investigate whether long-term use of an ergonomic keyboard was effective in reducing symptom severity and improving functional status for individuals who experience symptoms of work related upper extremity disorders (WRUED). PARTICIPANTS: Twenty-nine symptomatic workers employed by a single company. METHODS: Participants were assessed after using an ergonomic keyboard for an average of 34 months. Symptom severity, clinical signs, functional status, and typing speed were measured and compared with baseline and six-month study data. RESULTS: Repeated-measure analysis identified that participants maintained the improvement realized at the six-month study mark for symptom severity and functional status, and maintained their typing speed and accuracy. CONCLUSIONS: The results of the study suggest that continuous ergonomic keyboard use was effective in maintaining improvements obtained after six months of use. The potential for ergonomic keyboard use in preventing injury in keyboard operators warrants further investigation.

Burn therapists' opinion on the application and essential characteristics of a burn scar outcome measure.

Comprehensive burn rehabilitation requires the use of an appropriate burn scar outcome measure (BSOM). The literature reports many BSOMs; however, an objective, practical, inexpensive, valid, reliable, and responsive instrument eludes us. A problem in the development of such a measure is disagreement in which scar properties to include. The objective of this study was to determine the burn scar variables that therapists believe should be included in a BSOM. An Internet survey was administered to burn occupational and physical therapists. The response rate was 38.6% (105 surveys). Of the respondents, 38.1% use a BSOM; of those, 75% use the Vancouver Scar Scale. Reasons why respondents do not use a BSOM (61.9%) are because they are not familiar with available measures, have not found one that is clinically practical, or need more training. The majority (95%) believes that using a BSOM is important, and the following BSOM characteristics were reported as important: reliable, valid, quick, easy, and noninvasive. Respondents indicated that the following properties should be included in a BSOM: pliability (96.2%), vascularity (92.4%), height (87.6%), appearance (75.2%), skin breakdown (74.3%), itch (73.3%), surface texture (70.5%), pigmentation (68.6%), and pain (67.6%). This study suggests that using a BSOM is important despite its inconsistent use, and BSOM education may be valuable. The top three agreed-upon properties for inclusion are already incorporated into the most commonly used BSOM-the Vancouver Scar Scale-suggesting that modifications may be reasonable.

Participation in community-based activities of daily living: comparison of a pushrim-activated, power-assisted wheelchair and a power wheelchair.

PURPOSE: The purpose of this study was to evaluate pushrim-activated, power-assisted wheelchair (PPW) performance among dual-users in their natural environment to determine whether the PPW would serve as a satisfactory alternative to a power wheelchair for community-based activities. METHODS: A concurrent mixed methods research design using a cross-over trial was used. The outcome measures used were number of hours reported using the different wheelchairs, Quebec User Evaluation of Satisfaction with assistive Technology (QUEST), Functioning Everyday with a Wheelchair (FEW), Psychosocial Impact of Assistive Devices Scale (PIADS) and Canadian Occupational Performance Measure (COPM). RESULTS: The number of hours spent participating in self-identified activities was not significantly different. Only the Self-Esteem subscale of the PIADS identified a statistically significant difference between the PPW and power wheelchair conditions (p = 0.016). A clinically important difference for Performance and Satisfaction was suggested by the COPM, in favour of the power wheelchair. CONCLUSIONS: Additional knowledge was gained about the benefits of PPW technology. Participants were able to continue participating independently in their self-identified community activities using the PPW, and identified comparable ratings of satisfaction and performance with the PPW and the power wheelchair. For some individuals requiring power mobility, the PPW may provide an alternative to the power wheelchair.

The effect of alternate style keyboards on severity of symptoms and functional status of individuals with work related upper extremity disorders.

UNLABELLED: There is evidence that performing job tasks involving repetition, vibration, sustained posture or forceful movement may contribute to symptoms of work related upper extremity disorders. Typing is one such activity; symptoms that develop as a result of this activity can affect performance of work, self-care and leisure occupations. Studies investigating the impact of ergonomic keyboards on symptom reduction are limited, and little research exists regarding the reduction of key activation force as an intervention. METHODS: This randomized, prospective study used a sample of 68 symptomatic workers employed by a single company. One group received a commercially available ergonomic keyboard, a second group used a modified version of the same keyboard designed to reduce activation force, vibration and key travel. We measured symptoms and clinical signs, functional status, and device satisfaction in both groups over a six-month study period. CONCLUSIONS: Between-groups analyses indicated that the groups performed similarly on the outcomes of interest. Repeated-measure analysis identified a reduction of symptoms, an improvement in functional status, preference for and increased satisfaction with the intervention keyboards, and maintenance of typing speed and accuracy for both groups.

Musculoskeletal injuries among ultrasound sonographers in rural Manitoba: a study of workplace ergonomics.

The purpose of this study was to compare the epidemiology of musculoskeletal injuries and workplace ergonomics among rural-based sonographers compared to urban-based sonographers. The authors also tested the use of a biomechanical software program to assess load on the spine and upper extremity joints. A mail-in survey was sent to all practicing sonographers in rural Manitoba, and on-site video-taped ergonomic and biomechanical evaluations were completed for four sites. Rural-based sonographers appear to have greater work stress related to waiting lists, use of outdated and non-adjustable equipment, and high client load. They also do not advocate for better working conditions because they are few in number and geographically distant from one another. Use of the biomechanical software proved minimally useful. Information related to industry standards and greater collaboration is needed to promote workplace health for sonographers.
