Accuracy of clinical observations of push-off during gait after stroke.
OBJECTIVE
To determine the accuracy (criterion-related validity) of real-time clinical observations of push-off in gait after stroke.


METHODS
Criterion-related validity study of gait observations.


METHODS
Rehabilitation hospital in Australia.


METHODS
Eleven participants with stroke and 8 treating physical therapists.


METHODS
Not applicable.


METHODS
Pearson product-moment correlation between physical therapists' observations of push-off during gait and criterion measures of peak ankle power generation from a 3-dimensional motion analysis system.


RESULTS
A high correlation was obtained between the observational ratings and the measurements of peak ankle power generation (Pearson r =.98). The standard error of estimation of ankle power generation was .32W/kg.


CONCLUSIONS
Physical therapists can make accurate real-time clinical observations of push-off during gait following stroke.
