Objectives:
To investigate (1) rates of powered wheelchair use and level of user-rated functional performance at one-month follow-up, and (2) whether psychological variables were prospectively predictive of outcome.
Design:
Prospective follow-up study.
Setting:
UK hospital-based regional rehabilitation and mobility centre.
Participants:
Volunteer adults with impaired mobility. Of 155 approached, 103 had baseline assessments. Of these, 81 (79%) provided outcome data. Mean age was 65.6 years (SD = 13.5); 55% were male.
Main Outcome Measures:
Rate of day-to-day powerchair use, and users' perceptions of how well the powerchair allowed them to perform functional tasks.
Results:
Among those with indoor-only chairs, 48% were 'less frequent' users; this rose to 72% among those with indoor/outdoor chairs. Excluding environmental reasons, rate of indoor use was predicted by baseline measures of verbal recall (P<0.001), figure copying (P=0.003) and global cognition (P=0.021). Among those with indoor/outdoor chairs, total rate of use was predicted by verbal recall (P= 0.001). Participants reported that the powerchair was effective in meeting their functional needs.
Conclusions:
Powered wheelchair use was predicted by cognitive measures. Rates of use were relatively low, despite users' reports that the powerchair facilitated their everyday functioning well.
