This study investigated whether obstacle crossing performance differs between the
first and subsequent attempts in people recovering from stroke.
Thirty two people
with stroke performed eight trials stepping over a 4 cm high obstacle.
Spatiotemporal measures of gait were captured by a Vicon 3D motion analysis
system. Data collected only from those subjects who completed three trials
leading with the affected limb or three trials leading with the unaffected limb
were analysed. These criteria resulted in data from only 22 subjects being used
in the analysis. Repeated measures MANOVA analyses showed no differences in the
spatiotemporal data between the first, second or third trials when leading with
either the affected (p=.317) or unaffected limb (p=.801). In general, intraclass
correlations showed there were moderate to strong correlations for the
spatiotemporal data across the trials (.612-.952), with the exception of trail
step time (.480). These results show there are no differences between the
spatiotemporal data collected in the first, second and third obstacle crossing
trials. This suggests data from a single trial can be considered representative
of performance in people with stroke.
