Conditioning Neural Circuits to Improve Upper Extremity Function
In Brief
A clinical study evaluating transcranial direct current stimulation, peripheral nerve somatosensory stimulation, and 1 other intervention for Spinal Cord Injury and Tetraplegia. Completed, enrolled 80 participants across 1 site.
Detailed Summary
Non-invasive brain stimulation has gained increasing popularity and research support over the past several years. Recent research indicates that it might have benefits for improving hand function in people with spinal cord injury. The purpose of this study is to evaluate the effects of a type of non-invasive brain stimulation, known as tDCS, on hand function.
Study Details
Timeline
Interventions
High-definition transcranial direct current stimulation is applied over the hand area of the primary motor cortex (M1). Parameters= 2mA for 20 minutes. Functional task practice will be completed concurrently with tDCS and for approximate 40 minutes after the stimulation stops.
Electrical stimulation will be applied to the median nerve of the primary hand being trained at parameters that elicit a sensory but not motor response (called "peripheral nerve somatosensory stimulation"). Stimulation parameters are 100Hz with a 250uS pulse width. Stimulation intensity will vary between 1-10mA per participant. Stimulation will be applied for 1 hour and functional task practice will be completed concurrent with the stimulation.
During sham transcranial direct current stimulation (tDCS), a sham tDCS device will be used along with functional task practice. The sham tDCS unit will be used for the first 20 minutes of FTP, followed by an additional 40 minutes of FTP.
