A multimodal training with visual biofeedback in subacute stroke survivors: a randomized controlled trial

Area of Science:

• Neurorehabilitation
• Biomedical Engineering
• Physical Therapy

Background:

• Early patient involvement is crucial for gait restoration and motor recovery post-stroke.
• Multimodal biofeedback training combines cycling, functional electrical stimulation (FES), and balance exercises.

Purpose of the Study:

• To assess the impact of multimodal biofeedback training on walking ability and motor recovery in subacute stroke survivors.
• To compare the efficacy of this training against usual care.

Main Methods:

• A randomized controlled trial involving 68 subacute stroke survivors.
• Experimental group received biofeedback FES-cycling and balance training plus usual care.
• Control group received only usual care. Outcomes measured included gait speed, spatiotemporal parameters, and functional assessments.

Main Results:

• Both groups improved, but the experimental group showed a significantly higher percentage achieving meaningful gait speed improvement (73% vs 38%).
• Patients with moderate to severe baseline gait impairment experienced the most benefit (91% vs 36% improvement).
• No statistically significant group or interaction effects were found for all measured outcomes.

Conclusions:

• Multimodal biofeedback training demonstrated a positive trend in locomotion recovery, especially for severely impaired patients.
• While not statistically superior to usual care, it offers a potentially effective, low-supervision early rehabilitation option.
• Task-specific, repetitive, and intensive training may be optimized for group sessions, potentially reducing staff ratios.
