Effect of tSCS on Ankle Movement Training in Individuals With SCI

Effect of tSCS on Ankle Movement Training - Evidence From Spinal Circuitry Adaptation in Individuals With SCI

Important: This information is not medical advice. Talk to your doctor about whether a clinical trial is right for you.

About This Trial

This clinical trial explores the effectiveness of transcutaneous spinal cord stimulation (tSCS), a non-invasive technique, in facilitating spinal circuitry adaptation in individuals with spinal cord injury (SCI). While epidural spinal cord stimulation (eSCS) has shown functional benefits, its application is limited by the side effects associated with implanted electrodes. tSCS, which shares a similar mechanism but does not require surgery, has yet to be extensively studied in large human trials. The study aims to: Determine optimal tSCS parameters for non-invasive spinal stimulation. Investigate the priming effect of tSCS on spinal circuitry during machine-assisted ankle movement training. Examine the long-term clinical outcomes of combining tSCS with ankle movement training in individuals with incomplete SCI. The trial will include both healthy participants and individuals with complete and incomplete SCI, using the soleus post-activation depression (PAD) model to evaluate spinal circuitry adaptation. The results will provide insights into spinal re-adaptation and potentially introduce a novel, non-invasive approach for SCI rehabilitation.
