The Efficacy of Gait Training Using a Body Weight Support Treadmill and Visual Biofeedback in Patients with Subacute Stroke: A Randomized Controlled Trial

Abstract EN

Background.

This study was designed to determine whether or not gait training based on the use of treadmill with visual biofeedback and body weight support (BWS) would produce better effects in patients with subacute stroke compared to BWS treadmill training with no visual biofeedback.

Materials and Methods.

30 patients with subacute stroke were randomly assigned to do body weight supported treadmill training with visual biofeedback (BB group) or BWS treadmill training without visual biofeedback.

Their gait was assessed with a 3D system (spatiotemporal gait parameters and symmetry index) and by means of 2-minute walk test (2 MWT), 10-metre walk test (10 MWT), and Timed Up & Go test.

Subjects in both groups participated in 15 treadmill training sessions (30 minutes each).

Results.

The participants from both groups achieved a statistically significant improvement in spatiotemporal gait parameters, walking speed, endurance, and mobility.

The average change in the BB group after the end of the programme did not differ significantly compared to the change in the control group.

The change in the symmetry index value of stance phase in the BB group was 0.03 (0.02) and in the control group was 0.02 (0.02).

The difference was not statistically significant ( p = 0.902 ).

The statistically significantly higher improvement in the BB group was found in the range of walking speed ( p = 0.003 ) and endurance ( p = 0.012 ), but the difference between groups was of low clinical significance.

Conclusions.

The findings do not confirm that BWS treadmill training with the function of visual biofeedback leads to significantly greater improvement in gait compared to BWS treadmill training with no visual biofeedback at an early stage after stroke.
