Individuals with chronic cervical spinal cord injury (SCI) and tetraplegia commonly experience persistent impairment in upper limb function, leading to reduced independence and quality of life. Transcutaneous spinal cord stimulation (tSCS) is a non-invasive neuromodulation technique that has demonstrated potential to improve upper limb strength and function when combined with rehabilitation. However, access to tSCS is limited in Singapore due to cost, regulatory barriers, and the need for frequent outpatient therapy.
This study evaluates the safety, efficacy, and feasibility of a home-based digital rehabilitation program incorporating tSCS delivered using a commercially available neuromuscular electrical stimulation (NMES) device. Using a prospective, open-label single-case experimental design with multiple baselines across participants, individuals with chronic, non-progressive cervical SCI will receive daily home-based tSCS combined with an mobile application-guided upper limb exercise program. Upper limb function, quality of life, feasibility, and safety outcomes will be assessed longitudinally over a 22-week study period.
