Electrical Stimulation for Motor Function Recovery in Spinal Cord Injury: A Randomized Controlled Trial

Electrical Stimulation for Motor Function Recovery in Spinal Cord Injury: A Randomized Controlled Trial

Introduction: Spinal cord injury (SCI) is a debilitating condition that can lead to partial or complete loss of motor function below the injury site. Electrical stimulation (ES) has shown promise in promoting motor function recovery in SCI patients, but the optimal parameters for ES remain unclear. This study aimed to investigate the impact of ES on motor function recovery in SCI patients and determine the most effective ES parameters.

Methods: This randomized controlled trial included 60 SCI patients randomly assigned to one of three groups: (1) ES group, (2) sham ES group, and (3) control group. The ES group received ES for 30 minutes daily, five days a week, over 12 weeks. The sham ES group received a placebo ES, while the control group received no intervention. Motor function was assessed using the International Standards for Neurological Classification of Spinal Cord Injury (ISNCSCI) before and after the intervention.

Results: The ES group demonstrated significant improvement in motor function compared to both the sham ES and control groups. Specifically, the ES group showed a notable increase in muscle strength, range of motion, and motor scores on the ISNCSCI. The optimal ES parameters were found to be a frequency of 30 Hz, a pulse width of 200 μs, and a duration of 30 minutes.

Conclusion: ES is an effective intervention for improving motor function recovery in SCI patients. The optimal parameters of ES, as identified in this study, are a frequency of 30 Hz, a pulse width of 200 μs, and a duration of 30 minutes. These findings hold significant implications for the development of effective rehabilitation programs for SCI patients.
