NCT ID NCT03892746

What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now
This trial is taking on new participants right now.
Not yet recruiting
Registered, but not yet taking participants.

Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.

Summary

This study tested a new approach to help people with cervical spinal cord injury improve arm and hand function. Participants received non-invasive brain stimulation combined with upper limb training over several weeks. The goal was to see if this combination could strengthen muscles and improve daily living skills. The study involved 47 adults with incomplete spinal cord injury at least one year after injury.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion Criteria: * Patients with incomplete (having sparing to muscles in the upper extremities below the level of injury) C1-C8 SCI * at least 1 year post injury * weakness of the triceps or biceps muscle in the weaker upper limb, defined as a clinically detectable difference in power compared to the power of the spared antagonist(biceps and triceps respectively) muscle, i.e., at least one muscle grade lower on the MRC scale. Exclusion Criteria: * contraindications to tDCS and TMS including: pacemaker, metal in the skull, seizure history, pregnancy. * pressure ulcers * traumatic brain injury (TBI), diagnosed based upon acute injury Rancho scale \<5 or positive MRI/CT findings at the time of injury will also be excluded to prevent confounding of TMS metrics. * excessive tone/spasticity and severe contractures or soft tissue shortening at the elbow/wrist * participating in ongoing upper-limb therapies
