Clinical Trial Summary

The goal of this study is to:

1. Assess the usability of the SynPhNe device in a home environment.

2. Evaluate the efficacy of the SynPhNe home use device to improve motor hand function in chronic stroke subjects when used with a few sessions of standard care, as compared to standard care alone.

Description:

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 when it is used with a few sessions of research 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.

We are combining the use of the device with a research oriented rehabilitation program in a supervised environment. The SynPhNe system has not been approved by the U.S. Food and Drug Administration.

Subjects will be randomized by chance (like a coin toss) to one of the two groups: lab-based upper extremity research therapy alone or lab-based upper extremity research therapy in addition to 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 last 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. Subjects will either be using the SynPhNe system or use 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.

Intervention

Device:
• SynPhNe platform
SynPhNe is a non-invasive device. It consists of a piece worn around the forearm, a head component and it communicates wirelessly with the computer to provide feedback while performing motor tasks with the hemiparetic hand. The head cap records brain activity and gives feedback to help relaxing while exercising. The arm and the head component communicate wirelessly with the computer via Bluetooth. The head component reads brain signals while the arm gear senses your muscle signals when performing the exercises. The computer software adopts the appropriate difficulty level, speed and duration of the exercise depending on brain and muscle status to minimize fatigue.

Other:
• Conventional therapy
Exercise program established with a therapist (8 sessions under therapist direct supervision and 10 sessions at home). Low functioning subjects will be given more proximal joint-muscle exercises and activities while higher functioning subjects will have a greater component of distal tasks and activities. The therapist will review the exercises therapy plan with the subject and re-adjust it.

Outcome

Type	Measure	Description	Time frame	Safety issue
Other	Goniometry - Active Range of Motion	Upper-extremity range of motion	Changes from baseline scores at Baseline, at 7 weeks and at one month follow-up
Other	Manual Muscle Testing (Kendall)	Muscle strength assessed by a therapist following Kendall guidelines. Scores range from 0 (no contraction) to 5 (maximum strength)	Changes from baseline scores at Baseline, at 7 weeks and at one month follow-up
Other	WHO-ICF problem solving form	Identification of participant's problems at the function, activity and environmental factors levels, following the World Health Organization International Classification of Functioning Codes. Decrease in number of problems identified at baseline indicates better outcomes.	Changes from baseline scores at Baseline, at 7 weeks and at one month follow-up
Other	Device satisfaction feedback questionnaire (only for intervention group)	Questionnaire to gather satisfaction feedback about usage of the device. Questions are scored from 1 to 5, total score up to 25. Higher score indicate higher satisfaction with the device.	Scores at 7 weeks
Other	Number of sessions completed (only for intervention group)	Log of completed sessions by the software. Higher number indicates better adherence to the intervention.	Scores at 7 weeks
Other	Number of issues encountered with the device and/or software (only for intervention group)	Number of occurrences of device and/or software malfunction.	Scores at 7 weeks
