Assessment of a Physio-neuro Platform (SynPhNe) for Home-based Retraining of Hand Function in Stroke Survivors

The goal of this study is to explore if the SynPhNe system can be used easily at home for people who suffered a stroke. With this study, we are also investigating if the SynPhNe system used could improve your hand function in comparison to conventional therapy. SynPhNe is a non-invasive device. It consists of a piece worn around the forearm, a head component and it communicates wirelessly via Bluetooth with the computer to provide subject with feedback while performing motor tasks with their hand. The head cap records your brain activity and gives feedback to help relaxing while exercising. The SynPhNe system has not been approved by the U.S. Food and Drug Administration. Study participants will be randomized by chance (like a coin toss) to one of the two groups: lab-based upper extremity research therapy or the SynPhNe system for home-based exercises. * The lab-based upper-extremity research therapy in its content is similar to regular occupational therapy and will focus exercise movements of arm and hand. * The group testing the SynPhNe system at home will have the system lent at no cost. The study lasts for up to 12 weeks and involves up to 22 sessions in total: * Up to 3 sessions will be for testing arm movements (at baseline, after research therapy and at 1 month follow-up). * 18 research therapy sessions. 10 of them will be done at Spaulding Rehabilitation Hospital with a therapist and 8 of them by yourself, at home. Study participants will either be using the SynPhNe system or the therapy plan recommended by the therapist, depending on the randomization. Each of these visits will be an hour long. They will be scheduled 3 days per week for six weeks.
