Combined TMS-tSCS for Lower Limb Rehabilitation in Chronic Incomplete SCI
Sponsor: National University Hospital, Singapore
Summary
he goal of this clinical trial is to learn if combined brain and spinal cord stimulation using TMS-tSCS can improve leg strength and walking recovery in adults with chronic incomplete spinal cord injury. The main questions it aims to answer are: Does combined TMS-tSCS improve lower limb motor function more than tSCS alone? Is combined TMS-tSCS safe and does it improve walking speed, independence, muscle activity, spasticity, and nerve pathway function? Researchers will compare combined TMS-tSCS with tSCS alone with sham TMS to see if adding brain stimulation leads to better recovery than spinal stimulation alone. Participants will: Attend 32 treatment sessions over 16 weeks. Receive either combined TMS-tSCS or tSCS with sham TMS. Undergo assessments of leg strength, walking speed, daily function, muscle stiffness, muscle activity, and nerve pathway function before and after treatment.

Transcranial Magnetic Stimulation
Repetitive transcranial magnetic stimulation (rTMS) is a non-invasive brain stimulation technique that enhances cortical excitability and corticospinal drive. Intermittent theta burst stimulation (iTBS), a brief patterned form of rTMS, produces lasting facilitatory effects and is more time-efficient. Evidence indicates rTMS improves motor function, reduces spasticity, and enhances neuroplasticity in SCI.
Transcutaneous Spinal Cord Stimulation
Transcutaneous spinal cord stimulation (tSCS) is a non-invasive neuromodulation technique that delivers electrical stimulation over the spine to activate sensory afferents and enhance spinal motor circuit excitability. Early studies showed it can enable voluntary movement even in motor-complete spinal cord injury (SCI), with subsequent research demonstrating improvements in motor function, standing, and walking in incomplete SCI. Evidence suggests tSCS modulates both spinal and corticospinal pathways, supporting neuroplasticity. The Up-LIFT trial (2024) provided strong clinical evidence, showing that tSCS combined with rehabilitation significantly improved upper limb strength and function in chronic cervical SCI, with 72% of participants meeting effectiveness endpoints and no serious adverse events. Later studies confirmed its safety in home and community settings, though standardization and larger trials remain needed.
