Overview
Brief Summary
This study aims to verify whether epidural electrical stimulation (EES) of the cervical spinal cord can activate muscles of the upper limbs in people with hemiplegia following a stroke.
Detailed Description
The purpose of this study is to verify whether epidural electrical stimulation (EES) of the cervical spinal cord can activate muscles of the arm and hand in people with hemiplegia following stroke. Participants will undergo a surgical procedure to implant a system that provides epidural electrical stimulation (EES) of the cervical spinal cord. After surgery, Participants will undergo a structured physical rehabilitation program and electrical stimulation. Researchers will quantify the motor potentials in the arm and hand muscles generated by EES of the cervical spinal cord, tune optimal stimulation parameters to induced arm and hand movement, and assess participant motor function of the upper limb with standard clinical tests and simple motor tasks.

Outcomes
Primary Outcomes
Change in motor functioning and sensation as measured by the Fugl-Meyer Assessment (FMA)
Time Frame: Time Frame: Baseline; at 1 - 4 - 7 - 13 - 19 - 25 months after the implantation
The Fugl-Meyer Assessment (FMA) is a stroke-specific, performance-based impairment index. It is main assesses motor functioning and sensation in patients with post-stroke hemiplegia. It is applied clinically and in research to determine disease severity, describe motor recovery, and plan and assess treatment. The upper extremity motor function score ranges from 0 to 66.
Change dexterity of the upper limb as measured by the Action Research Arm Test (ARAT)
Time Frame: Time Frame: Baseline; at 1 - 4 - 7 - 13 - 19 - 25 months after the implantation
Use the Action Research Arm Test (ARAT) assessment to quantify functional hand and arm dexterity. The score ranges from 0 to 57, with a higher value indicating better function.
Secondary Outcomes
- Change in spasticity as measured by the Modified Ashworth Scale (MAS)(Time Frame: Baseline; at 1 - 4 - 7 - 13 - 19 - 25 months after the implantation)
- Change in Quality of Life (QOL) as measured by the World Health Organization Quality of Life (WHOQOL-BREF)(Baseline; at 1 - 4 - 7 - 13 - 19 - 25 months after implantation)
