Spinal Stimulation With Gait Training to Improve Lower Limbs Motor Recovery in Spinal Cord Injury

Spinal cord injury (SCI) often results in partial or complete loss of movement. In the subacute phase (\< 6 months), the central nervous system shows increased potential for neuroplasticity, making it more responsive to rehabilitation and external stimulation. Standard care in rehabilitation centers relies on activity-based therapy (ABT), which uses intensive, task-specific training to promote recovery. Although ABT can improve mobility, its effects are often limited due to the nature of SCI and the indirect activation of neural circuits. Recent findings suggest that adding transcutaneous spinal cord stimulation (tSCS) to ABT in chronic SCI (\> 12 months) can enhance lower-limb motor recovery. This study will evaluate whether combining tSCS with gait training is safe and feasible in individuals with subacute SCI and whether it improves lower-limb motor outcomes compared with gait training alone. The investigators hypothesize that pairing gait training with tSCS early after injury will be safe and feasible and that tSCS delivered during gait training will augment leg muscle activation and lead to greater functional improvements. The study will also assess the feasibility, safety and tolerability of implementing this combined intervention in a intensive functional rehabilitation setting.
