tSCS + UL Robotics Training in SCI Patients

This study is aimed to evaluate whether transcutaneous spinal cord stimulation (tSCS) can augment upper limb robotic training (ULRT) to improve functional mobility in participants with chronic spinal cord injuries. It also evaluates the impact of the tSCS+ULRT on health-related quality of life (HRQOL), compared to ULRT alone. This is a prospective single-arm crossover study in participants with incomplete chronic traumatic spinal cord injury. 6 to 8 subjects with C2-8 level injuries will be recruited. The intervention includes Phase 1 of training which consists of 16 sessions of ULRT + conventional occupational therapy in 8-10 weeks, and Phase 2 of training which consists of 16 sessions of ULRT training + tSCS + conventional occupational therapy in 8-10 weeks. Outcome measures including mobility function assessment and neuromuscular assessment will be collected at Baseline, Post-Phase 1, Post-Phase 2, and 4 weeks Follow-up. A satisfaction survey on the intervention \"ULRT training + tSCS + conventional physiotherapy\" will be performed at end of the study.
