Although rehabilitation and emerging neuromodulation approaches can support meaningful gains, many individuals experience persistent limitations in reaching and grasping. Current noninvasive stimulation strategies typically target the brain OR the spinal cord alone, despite strong reciprocal interactions between these structures. Cervical transcutaneous spinal cord stimulation (tSCS) can enhance upper limb function. Cerebellar stimulation, given its key role in sensorimotor integration and modulation of corticospinal excitability, represents a promising but underexplored therapeutic target. Theta burst stimulation (TBS), a rapid form of repetitive transcranial magnetic stimulation (TMS), induces lasting changes in cortical excitability and may promote associative plasticity when paired with spinal cord stimulation. This double-blind, randomized, sham-controlled pilot trial (n=24) will evaluate the feasibility, preliminary efficacy, and mechanisms of combined cerebellar TBS + cervical tSCS in people with chronic cervical SCI (AIS B, C or D). Participants will either receive cerebellar TBS + cervical tSCS, tSCS only, or sham stimulation while engaging in functional task practice such as pinching and grasping 3x\u002Fweek for 8 weeks. Feasibility outcomes include adherence, retention, and safety. Efficacy will be assessed using the GRASSP strength sub-score and KINARM-based measures of sensorimotor control. Mechanistic outcomes will assess changes in cortical and spinal cord functional connectivity using resting state fMRI, corticospinal excitability using motor evoked potentials, and spinal excitability using the H reflex. Findings will establish whether combined cerebellar TBS and cervical tSCS is feasible, safe, and capable of enhancing upper limb recovery.",[87],"Spinal Cord Injuries and Disorders (SCI\u002FD)",[89,90,91,92,93,94,95,96],"Spinal cord injury","Transcutaneous Spinal Cord Stimulation","Cerebellar Theta Burst Stimulation","Arm and Hand Function","Upper Limb Motor Control","Transcranial Magnetic Stimulation","Neuroimaging","Neurophysiology","NOT_YET_RECRUITING","2026-02-13",{"date":100,"type":101},"2026-02-20","ACTUAL",{"date":103,"type":81},"2026-03-01",{"date":105,"type":81},"2031-02-28",{"name":5,"class":6},1]
