OBJECTIVE: To explore the extent and nature of change in cognitive-motor interference (CMI) among rehabilitating stroke patients who showed dual-task gait decrement at initial assessment. DESIGN: Experimental, within-subjects, repeated measures design. SETTING: Rehabilitation centre for adults with acquired, nonprogressive brain injury. SUBJECTS: Ten patients with unilateral stroke, available for reassessment 1-9 months following their participation in a study of CMI after brain injury. MEASURES: Median stride duration; mean word generation. METHODS: Two x one-minute walking trials, two x one-minute word generation trials, two x one-minute trials of simultaneous walking and word generation; 10-metre walking time; Barthel ADL Scale score. RESULTS: Seven out of ten patients showed reduction over time in dual-task gait decrement. Three out of ten showed reduction in cognitive decrement. Only one showed concomitant reduction in gait and word generation decrement. CONCLUSION: Extent of CMI during relearning to walk after a stroke reduced over time in the majority of patients. Effects were more evident in improved stride duration than improved cognitive performance. Measures of multiple task performance should be included in assessment for functional recovery.
