New brain stimulation technique aims to boost hand recovery in spinal cord injury patients
NCT ID NCT06440538
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This early-phase study at the Cleveland Clinic is testing whether combining a type of brain stimulation (paired neurostimulation) with hand training on one side can improve hand movement and dexterity on both sides in people with cervical spinal cord injury. Seventeen participants with injuries between C4 and C8 will undergo the treatment and be measured for changes in hand speed, finger control, and brain activity. The goal is to understand how the brain and spinal cord adapt, not to cure the injury.

Inclusion Criteria: * Neurological Level of Injury C4, C5, C6, C7, C8 * American Spinal Injury Association Impairment Scale (AIS) C-D * greater than or equal to 1 year time post injury * residual motor sparing of bilateral FDI muscles, defined as medical research council (MRC) grade 2 to 5 Exclusion Criteria: * contraindications to transcranial magnetic stimulation (TMS) and peripheral nerve stimulation (PNS) including pacemaker, metal in the skull, seizure history, pregnancy, etc. * history of alcohol and/or drug abuse * current usage of medications that can potentially lower the seizure threshold such as bupropion, amphetamines, etc. * history of other neurological conditions such as stroke, Parkinson's, and traumatic brain injury (TBI) * active pressure ulcers to avoid disruption of ongoing medical treatments * participation of on-going upper-limb therapies to minimize confounding effects * excessive tone/spasticity (Modified Ashworth Scale \[MAS\] \>3) and severe contractures or soft tissue shortening at elbow/wrist/fingers
