Passive standing as an adjunct rehabilitation intervention after stroke: a randomized controlled trial

BACKGROUND: Early physical rehabilitation enhances functional recovery in stroke survivors. Supported standing is a common adjunctive therapeutic practice in subjects with several central nervous diseases who are unable to stand actively. Data on the effect of supported positioning on standing frames in individuals with recent stroke are scarce and contradictory. OBJECTIVES: To verify if the addition of supported standing practice (SSP), delivered by means of a standing frame in two durations, to conventional physical therapy (CPT), may improve motor function, autonomy, and mobility in individuals with disability due to recent stroke. METHODS: After baseline assessment, 75 participants with severe disability due to stroke, all receiving CPT, were randomly assigned to adjunctive 20 or 40 min of SSP, or CPT only (control). Motor function, autonomy, and mobility were assessed before and after training, and three months later. RESULTS: All participants assessed received the planned dose of intervention. No adverse events of SSP were detected. Most outcome measures improved from baseline through the end of treatment and in the follow-up in all groups; the extent of change was comparable across the three randomization groups. CONCLUSIONS: In this randomized trial, SSP was unable to provide any sizeable adjunctive benefit, above and beyond CPT, in subjects with recent stroke.
