Noninvasive spinal cord stimulation to improve arm function

Transcutaneous Spinal Cord Stimulation to Facilitate Recovery of Upper Extremity Function in Individuals With Stroke or Spinal Cord Injury - A Pilot Study

Phase2; Phase3 Interventional University of Alberta · NCT06596369

What this trial studies

This study investigates the effects of transcutaneous electrical stimulation (tcES) on upper extremity function in individuals with spinal cord injuries and stroke. It aims to explore how different stimulation parameters, such as electrode placement and frequency, influence neural excitability and motor function. Participants will undergo a combination of tcES and activity-based therapy, with assessments to evaluate improvements in upper extremity function. The study employs a comprehensive set of neurophysiological techniques to link stimulation effects with functional outcomes.

Who should consider this trial

Good fit: Ideal candidates include individuals aged 18 to 75 with cervical spinal cord injuries or upper extremity motor dysfunction post-stroke.

Not a fit: Patients with acute spinal cord injuries or those with severe motor dysfunction who cannot participate in rehabilitation activities may not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could significantly enhance upper extremity function in patients with spinal cord injuries and stroke.

How similar studies have performed: Previous studies have shown promise with invasive spinal cord stimulation, but the noninvasive approach being tested here is relatively novel.
