Neuromodulation for Spinal Cord Injury

This trial explores a new method to help people with spinal cord injuries improve hand function. Researchers are testing a noninvasive brain stimulation technique called Intermittent Theta Burst Stimulation, combined with hand exercises, to determine if it can enhance nerve signals and improve hand movement. Participants will receive either real or sham (placebo) treatments to compare their effects. Individuals who have had a cervical spinal cord injury for at least a year and can still activate certain hand muscles might be suitable candidates. As an unphased trial, this study provides a unique opportunity to contribute to groundbreaking research that could enhance rehabilitation options for spinal cord injuries.

The trial excludes people taking drugs that affect the central nervous system and lower the seizure threshold, like antipsychotic drugs. If you're on such medications, you might need to stop them to participate.

Research has shown that Intermittent Theta Burst Stimulation (iTBS) is generally safe for people with spinal cord injuries. Studies have found that iTBS can improve movement and reduce muscle tightness (spasticity) without causing major side effects. Specifically, patients who received real iTBS reported better movement in their lower limbs and less muscle tightness compared to those who received a placebo treatment.

Similarly, Paired Corticospinal Motoneuronal Stimulation (PCMS) has been tested for safety in people with long-term spinal cord injuries. Research suggests that PCMS can safely enhance voluntary movement by strengthening the connections between the brain and spinal cord. These studies reported no major negative side effects.

Researchers are excited about the neuromodulation techniques being tested for spinal cord injury because they represent a shift from traditional rehabilitation approaches like physical therapy and medication. Intermittent Theta Burst Stimulation (iTBS) and Paired Corticospinal Motoneuronal Stimulation (PCMS) aim to enhance neural plasticity, potentially leading to better recovery of movement and function. Unlike conventional treatments, these techniques target the nervous system directly to promote the repair and strengthening of neural connections. By potentially accelerating the recovery process and improving outcomes, these methods could offer a significant advantage over existing options.

Research has shown that intermittent theta burst stimulation (iTBS) can aid people with spinal cord injuries by enhancing movement and reducing muscle tightness. Studies have found that iTBS can ease arm use and lessen muscle stiffness after an injury. In this trial, participants may receive both iTBS and paired corticospinal motoneuronal stimulation (PCMS). PCMS has improved abilities like walking and gripping, with benefits lasting several months. It enhances signals between the brain and muscles, aiding better movement control. Together, these treatments offer hope for improving hand function in people with spinal cord injuries.¹²⁶⁷⁸
