Background: Symmetry of gait is an important component of rehabilitation in stroke patients. Insufficient weight-bearing causes gait asymmetry.
Objective: This study aimed to identify the immediate effects of sufficient weight-bearing on the forefoot during the stance phase using visual feedback.
Methods: Twenty-seven individuals with stroke enrolled in this study. All patients were evaluated for gait parameters with and without visual feedback. Visual feedback was provided through a smart application and a beam projector screen that showed a weight shift as a change in color. Spatiotemporal gait parameters were evaluated, resulting in values for a calculated symmetry index, in addition to heel % and toe % temporal values.
Results: Velocity and cadence were significantly decreased when visual feedback was provided (p< 0.05). Spatiotemporal parameters, except for bilateral step length, swing time of affected side, and single-limb support of less affected side, showed significant improvement (p< 0.05). The gait pattern of subjects was more symmetrical with visual feedback compared to non-visual feedback (p< 0.05). The toe-on time significantly improved on the affected side with visual feedback (p< 0.05).
Conclusion: This study suggests that visual feedback aids in the improvement of gait symmetry, forefoot weight-bearing on the affected side, and spatiotemporal parameters.
