RESUMO
OBJECTIVE: To test the hypothesis that able-bodied people simulating hemiplegia (using the hemiplegic-propulsion pattern [1 arm and 1 leg]) have as much difficulty performing wheelchair skills as people with hemiplegia. DESIGN: Single-blind, controlled comparison of 2 groups. SETTING: Kinesiologic laboratory in a rehabilitation center. PARTICIPANTS: Twenty wheelchair users with hemiplegia (HP group) (median age, 68y; 80% men) and 20 able-bodied participants (AB group) (median age, 67y; 75% men). INTERVENTIONS: The participants in the AB group simulated hemiplegia and received a brief period of wheelchair skills training. Participants in both groups were asked to attempt the 50 skills of the Wheelchair Skills Test, version 2.4 (WST 2.4). MAIN OUTCOME MEASURES: Total and subtotal percentage scores on the WST 2.4 and success rates for the 50 individual skills. RESULTS: The mean percentage WST scores for the AB group were significantly greater than those for the HP group for the total WST scores ( P <.001), the indoor skill level ( P <.001), and the community skill level ( P <.001), but the advanced skill level scores were 0% for both groups. On the individual skills, the AB group had success rates at least 25% higher than the HP group for 13 (26%) of the skills. Both groups were generally successful (>/=75% success rate) on 21 skills (42%). Both groups experienced difficulties (
