Spinal Cord Injuries And Disorders

This study plans to use systems that have been developed by Medtronic to investigate the use of cervical spinal cord stimulation to treat adults with upper limb hemiparesis resulting from a stroke. The spinal cord stimulation (SCS) will be combined with physical training to improve arm and hand motor control. The study is divided into three phases. In the first phase, after baseline assessments, participants will undergo a Physical Training Protocol (PTP) for 6 weeks including 3 sessions of 90 mins/session per week. After receiving the Medtronic implantable system, in Phase 2, they will then repeat the same PTP program in combination with spinal cord stimulation during the entirety of each of the rehabilitation sessions. Finally, in Phase 3, participants will go home, will not be able to use the stimulation at home but will participate in monthly assessments in the laboratory in which the functionality of the Medtronic system and their motor performances will be assessed for up to 6 months.
