OBJECTIVES: To test the hypotheses that self-reported manual wheelchair skills
capacity and performance are highly correlated and that capacity significantly
exceeds performance. DESIGN: Cross-sectional. SETTING: Rehabilitation center.
PARTICIPANTS: Manual wheelchair users (N=26) with a variety of diagnoses and an
average of 10.8 years of wheelchair experience. INTERVENTIONS: None. MAIN OUTCOME
MEASURE: We administered the questionnaire version of the Wheelchair Skills Test
version 4.1 (WST-Q), recording the participants' capacity and performance scores
on each of 32 skills. RESULTS: The mean total WST-Q capacity and performance
scores +/- SD were 72.5%+/-19.2% and 58.1%+/-21.2%. The Spearman rho correlation
coefficient between total WST-Q capacity and performance scores was .853
(P=.000). The mean difference +/- SD in total WST-Q scores (capacity minus
performance) was 14.4%+/-9.5% with a median of 10.9% (P=.000 on a Wilcoxon
signed-rank test). There were 9 (28%) of the 32 skills for which the
participants' mean capacity success rates were >/=20% higher than the mean
performance success rates. Of the reasons for not performing individual skills,
66% of the instances were because the participant lacked the capacity. A variety
of other reasons were given by participants for not performing skills of which
they were capable (eg, the situation was not encountered, it could be avoided, or
assistance was usually available). CONCLUSIONS: Manual wheelchair skills capacity
and performance are highly correlated but capacity exceeds performance, more so
for some skills than others. Although further study is needed, these findings
have implications for the assessment and training of wheelchair skills.
