Improving Upper Extremity Strength, Function, and Trunk Stability Using Wide-Pulse Functional Electrical Stimulation...

Area of Science:

• Neuroscience
• Rehabilitation Medicine
• Biomedical Engineering

Background:

• Spinal cord injury (SCI) often results in significant upper extremity (UE) dysfunction and impaired sitting balance.
• Traditional rehabilitation programs may not fully restore UE function or dynamic balance in individuals with tetraplegia.

Purpose of the Study:

• To evaluate the effectiveness of an intensive outpatient (OP) therapy program focused on UE training augmented with wide pulse/high frequency functional electrical stimulation (WPHF-FES).
• To assess improvements in UE function, strength, and dynamic sitting balance in individuals with SCI.

Main Methods:

• A prospective case series involving 50 individuals with tetraplegia undergoing OP therapy.
• Participants engaged in 60-minute UE functional task-specific practice combined with WPHF-FES, 5 times/week for an average of 72 sessions.
• Outcomes measured included the Capabilities of Upper Extremity Test (CUE-T), UE motor score (UEMS), and modified functional reach (MFR).

Main Results:

• Significant improvements were observed in the total CUE-T score (14.1 points, p < .0001).
• Participants also showed significant gains in UEMS (4.6 points, p < .0001) and MFR (13.6 cm, p < .0001).
• These improvements indicate enhanced UE strength, function, and dynamic sitting balance.

Conclusions:

• Intensive UE training combined with WPHF-FES leads to significant functional and balance improvements in individuals with tetraplegia.
• This approach shows promise for improving outcomes in OP SCI rehabilitation.
• Further comparative effectiveness studies are recommended to guide optimal treatment strategies.
