Effect of functional electrical stimulation-based mirror therapy using gesture recognition biofeedback on upper...

Area of Science:

• Neurorehabilitation
• Biomedical Engineering
• Physical Therapy

Background:

• Mirror therapy (MT) is a recognized upper extremity rehabilitation technique for stroke survivors.
• Recent advancements combine MT with neuromuscular electrical stimulation or EMG-triggered biofeedback.
• Investigating novel MT approaches is crucial for enhancing motor recovery in stroke patients.

Purpose of the Study:

• To evaluate the efficacy of functional electrical stimulation (FES)-based MT incorporating a motion recognition biofeedback device.
• To assess the impact of this combined intervention on upper extremity motor recovery in chronic stroke patients.

Main Methods:

• Twenty-six chronic stroke patients were randomly assigned to either a control (conventional MT) or experimental (FES-based MT with motion recognition biofeedback) group.
• Both groups received a conventional rehabilitation program.
• Interventions were administered for 30 minutes/day, 5 days/week, for 4 weeks, with pre- and post-intervention assessments.

Main Results:

• Both groups showed significant improvements in Fugl-Meyer assessment (FMA), manual function test (MFT), K-MBI, and active-range of motion (ROM).
• The experimental group uniquely demonstrated significant improvements in overall upper extremity recovery, ulnar, and radial deviation.
• Statistically significant differences favoring the experimental group were observed in Brunstrom's recovery level, FMA, MFT, and active-ROM changes.

Conclusions:

• FES-based MT utilizing gesture recognition biofeedback is an effective method for enhancing upper extremity motor recovery and function in chronic stroke patients.
• Integrating gesture-recognition biofeedback with FES-based MT provides supplementary therapeutic advantages.
• This innovative approach holds promise for improving functional outcomes in stroke rehabilitation.
