Utees with an average age of 61.9 years (SD = 15.7) who had lost their limb related to vascular (53.0%) or non-vascular (47.0%) etiology. Methods: Medical chart review, questionnaires (Frenchay Activities Index, Interpersonal Support Evaluation List, the Center for Epidemiology Studies – Depression scale, Prosthetic Evaluation Questionnaire mobility subscale, and the Activities-specific Balance Confidence Scale) and a QoL Visual Analogue Scale were assessed using multiple linear regression analysis. Results: The analysis revealed seven significant factors (depression, perceived prosthetic mobility, social support, comorbidity, prosthesis problems, age and social activity participation) as predictors of subjects' perceived QoL. Depression explained 30% of the variation, while the full model explained 42% of the variation. Conclusion: Several modifiable characteristics influence QoL after lower limb amputation including depression and participation in daily living. This finding suggests the importance of addressing individuals' affective status to regain or maintain QoL....

Purpose: There is limited information on the difficulties individuals experience in manoeuvring their power wheelchairs during daily activities. The aim of this study was to describe the nature and context of power wheelchair driving challenges from the perspective of the user. Methods: A qualitative design using semi-structured interviews with power wheelchair users. Qualitative content analysis was used to identify themes. Results: Twelve experienced power wheelchair users were interviewed. Findings revealed that power wheelchair driving difficulties were related to the accomplishment of activities of daily living, and the influence of environmental context. Four key themes emerged: (1) difficulties accessing and using public buildings-facilities, (2) outdoor mobility, (3) problems in performing specific wheelchair mobility tasks/manoeuvres and (4) barriers and circumstances that are temporary, unforeseen or specific to a particular context. Conclusion: This qualitative study furthers our understanding of the driving difficulties powered wheelchair (PW) users experience during daily activities. This knowledge will assist clinicians and researchers in two areas: in choosing assessment measures that are ecologically valid for power wheelchair users; and, in identifying and refining the content of training programs specific to the use of power wheelchairs.

Background. Confidence in one's ability to perform a given task can be a stronger predictor of performance than skill itself. There are currently no measures to assess confidence with manual wheelchair use. The objective of this study was to develop and assess the content validity of the Wheelchair Use Confidence Scale (WheelCon-M). Method. A two-phase mixed-methods design was used. Semi-structured interviews were conducted to generate items, followed by a Delphi survey for item selection. Persons who use a wheelchair, health care professionals, and researchers participated in both phases of the study. Results. An 84-item WheelCon-M was developed based on the qualitative data. After the Delphi survey, a final 62-item WheelCon-M was composed of the following six areas (number of items per area): Negotiating the Physical Environment (33 items), Activities Performed using a Manual Wheelchair (11 items), Knowledge and Problem Solving (6 items), Advocacy (4 items), Managing Social Situations (5 items) and Managing Emotions (3 items). Conclusion. This article reports the development and content validation of the WheelCon-M. As a scale to measure confidence with wheelchair use was not available prior to this work, clinicians now have a method of identifying individuals who have low confidence with wheelchair use.
