OBJECTIVE: To investigate whether the provision of power mobility would have an effect on body weight in adults who were first-time qualifiers for power mobility. DESIGN: This was a retrospective observational study of consecutive subjects, who served as their own controls. The medical records of 468 subjects who were approved for power mobility during a 17-mo period were reviewed. Three weight groups (12 mos before, at, and 12 mos after the power mobility evaluation) were evaluated with repeated-measures analysis of variance (ANOVA). The weight changes on subjects in different age groups (45-54, 55-64, 65-74, and >74), in geriatric vs. nongeriatric groups, and in different body mass index (BMI) groups were analyzed. RESULTS: Eighty-nine subjects met the inclusion criteria. They were obese (49.4%), and most of them were geriatric (64%). Congestive heart failure (30.34%) and chronic obstructive pulmonary disease (22.47%) were the two main presenting diagnoses. The repeated-measures ANOVA showed no significant weight change in the three studied weight groups. Similar results were seen in the age and BMI subgroups. CONCLUSIONS: There was no statistically significant weight change in adults who were first-time qualifiers and who used power mobility for 1 yr.
