Brain zaps and electric gloves: new hope for stroke survivors with severe hand paralysis?
NCT ID NCT03870672
First seen Jun 27, 2026 · Last updated Aug 27, 2026 · Updated 2 times
Summary
This study tests whether combining two non-invasive therapies can improve hand function in people who had a stroke at least six months ago and have severe arm weakness. The therapies are a brain stimulation technique called rTMS and a device that uses electrical stimulation to open the weak hand, controlled by a glove on the strong hand. Researchers will compare three treatment combinations to see which works best and for whom.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- repetitive transcranial magnetic stimulation (rTMS) and contralaterally controlled functional electrical stimulation (CCFES)
- What this could lead to
- If successful, this could lead to a new rehabilitation therapy that helps people with severe hand weakness after a stroke regain more use of their affected arm.
- What could go wrong
- This is an early-stage trial with only 72 participants, so results may not apply to everyone. The improvements may be small or not last long, and brain stimulation can cause discomfort or headache.

Inclusion Criteria: * age 18 to 90 years old at time of randomization * greater than 6 months since a first clinical cortical or subcortical, ischemic or hemorrhagic stroke * severe upper limb hemiparesis defined as less than 10° active wrist extension or less than 10° active thumb abduction/extension or less than 10° active extension in at least two additional digits (i.e., will not meet minimum CIMT criteria) * ability to follow 3-stage commands and can remember 2 items from a list of 3 items after 3 minutes * adequate active movement of shoulder and elbow to position the paretic hand on one's lap for performance of functional task practice and CCFES-assisted hand opening exercises * skin intact on hemiparetic arm * surface electrical stimulation of the paretic finger and thumb extensors produces functional hand opening without pain * able to hear and respond to cues from stimulator * completed occupational therapy at least 2 months prior to enrollment (no concomitant OT) * full volitional hand opening/closing of the non-paretic hand * ability to follow instructions for putting on and operating the CCFES stimulator or a caregiver available to provide assistance Exclusion Criteria: * metal implant in the head * history of seizures as an adult * history of alcohol or substance abuse less than 10yrs prior to enrollment * intake of anticonvulsants or anti-depressants contraindicated with TMS * cardiac pacemaker or other programmable implant
