Abstract
McGinley JL, Morris ME, Greenwood KM, Goldie PA, Olney SJ. 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. Design Criterion-related validity study of gait observations. Setting Rehabilitation hospital in Australia. Participants Eleven participants with stroke and 8 treating physical therapists. Interventions Not applicable. Main Outcome Measures 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.
