A clinical trial of an investigational, non-invasive medical device has shown that trans-spinal direct-current stimulation and peripheral nerve direct-current stimulation significantly reduced upper-limb spasticity in participants who had experienced a stroke.
The treatment involves passing a direct electrical current across the spinal cord with a skin-surface electrode, known as trans-spinal direct-current stimulation (tsDCS), and adding a peripheral direct-current stimulation (pDCS) in the paralyzed upper limb. There are additional benefits to patients when tsDCS is combined with pDCS, according to the study, which was led by researchers at the Feinstein Institutes for Medical Research in Manhasset, N.Y. and was published in Springer Nature’s Bioelectronic Medicine.
