Neuromodulation to Improve Grasping Function After SCI

Recruiting now · Not applicable · Has a placebo group

Conditions studied: Spinal Cord Injury

In brief

The goal of this study is to restore the activities of late descending signals with a noninvasive stimulation approach in combination with hand motor training to improve hand function in persons with cervical SCI. The main question it aims to answer is if the inputs to late descending signals above the level of injury and the output of residual late descending signals below the level of injury could be increased. Specifically, in the first part of the study, 30 participants will complete 2 randomized sessions to compare the effect of intermittent theta burst stimulation combined with paired corticospinal motoneuronal stimulation. In the second part of the study, 24 participants will complete either combined stimulation protocol or sham stimulation protocol with exercise training.
