Repetitive Nerve Stimulation to Improve Recovery After Stroke (RESTORES)
October 27, 2022 updated by: Hospital Israelita Albert Einstein
Comparison Between Mechanisms Underlying Effects of Repetitive Peripheral Nerve Stimulation on Upper Limb Motor Performance in the Subacute and Chronic Phases After Stroke
Upper limb paresis is the most common type of post-stroke neurological impairment and a major cause of functional disability.
Repetitive peripheral electrical stimulation (RPES) is a novel strategy to improve upper limb motor performance in the post-stroke chronic phase but its effects in the subacute phase are still poorly understood.
The objectives of this study are to compare the effects of RPES on motor performance of the upper limb in the subacute and chronic phases of stroke, and to identify the mechanisms underlying this intervention.

Arms and Interventions
Participant Group / Arm |
Intervention / Treatment |
---|---|
Active Comparator: Active, subacute stroke
Repetitive peripheral electrical stimulation (RPES) + Motor Training.
Active RPES will be administered for 2 hours.
After active session of RPES, the patient will receive motor training.
|
Active repetitive peripheral nerve stimulation will be applied to the median nerve of the affected forearm with surface electrodes.
The stimulator will be set to deliver bursts of 10 Hz stimulation at 50% duty cycle (500 ms on and off).
For active stimulation, intensities will be set at the highest intensity able to induce sensory paraesthesias without overt muscle contraction or pain, and adjusted if required.
|
Sham Comparator: Sham, subacute stroke
Sham Comparator: Sham + Motor Training.
Sham will be administered for 2 hours.
After sham, the patient will receive motor training
|
Sham repetitive peripheral nerve stimulation will be applied to the median nerve of the affected forearm with surface electrodes.
The stimulator will be set to deliver bursts of 10 Hz stimulation at 50% duty cycle (500 ms on and off).
For sham stimulation, intensities will be set at 10mv - 15mv lower than de lowest intensity able to induce sensory paraesthesias, and adjusted if required.
|
Active Comparator: Active, chronic stroke
Repetitive peripheral electrical stimulation (RPES) + Motor Training.
Active RPES will be administered for 2 hours.
After active session of RPES, the patient will receive motor training.
