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.
