Clinical Trial Summary

Stimulation of the spinal cord may induce the growth and reorganization of neural pathways leading to the re-animation of paralyzed limbs. Growing evidence indicates that electrical spinal cord stimulation improves motor functions immediately via modulating the excitability of spinal circuitry in patients with spinal cord injury. Recently, a novel, non-invasive, well-tolerated and painless transcutaneous electrical stimulation strategy was demonstrated to be effective for improving lower limb motor function in healthy individuals and in patients with spinal cord injury. The investigators hypothesize that transcutaneous cervical electrical stimulation can enhance conscious motor control and functions of hand and arm via neuromodulation of spinal network. This study is a prospective efficacy trial of transcutaneous cervical electrical stimulation for improving upper limb function in patients with traumatic or degenerative cervical spinal cord injury. Transcutaneous electrical spinal stimulation device is not regulated by the United States Food and Drug Administration for treatment of spinal cord injury. The interventions include either transcutaneous cervical spinal electrical stimulation combined with physical therapy or physical therapy only. The order of the interventions will be randomized for each subject in a delayed cross-over design. Total duration of the study is 6 months, including 4 weeks baseline measurements, 8 weeks intervention and 12 weeks follow-up. Both immediate and lasting improvements in hand motor and sensory function via transcutaneous cervical spinal stimulation will be evaluated.

Outcome

Type Measure Description Time frame Safety issue
Primary Graded and Redefined Assessment of Strength, Sensibility and Prehension test (GRASSP test) GRASSP is a clinical impairment measurement tool that quantifies hand impairment caused by cervical spinal cord injury. The tool measures three domains of function, including strength (manual muscle strength testing), sensibility (Semmes Weinstein monofilament sensation test) and prehension (ability and performance to generate various grasp and pinch movements using water bottle, jar, key, pegs, coins and nuts). 6 months
Secondary International Standards for Neurological Classification of Spinal Cord Injury (ISNCSCI) Examination Standard neurologic examination that is routinely used to determine the levels and severity of spinal cord injury. Includes manual muscle strength testing and dermatomal light touch and pin prick sensory examination. 6 months
Secondary Grip and pinch strength Hand strength measurement by grip and pinch dynamometry 6 months
Secondary Numeric Pain Rating Scale Patient reported pain rating 6 months
Secondary Penn Spasm score Patient reported spasm rating 6 months
Secondary Spinal Cord Independence Measure Clinician-administered disability questionnaire for patients with spinal cord lesions 6 months
Secondary WHO-Quality of life - BREF Patient reported quality of life scale 6 months
