Study Details
Study Description
Brief Summary
The goal of this study is to:
-
Assess the usability of the SynPhNe device in a home environment.
-
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.

Detailed 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.

Arms and Interventions
| Arm | Intervention/Treatment |
|---|---|
| Experimental: SynPhNe therapy Subjects will be asked to participate in a program of 18 upper-extremity rehabilitation sessions of 60 minutes with SynPhNe platform, over 6 weeks. The sessions will emphasize on the wrist and fingers movements, including functional activities. During week the two first weeks, 6 sessions will be done under therapist supervision at the Motion Analysis Laboratory at Spaulding Rehabilitation Hospital. Over the next 4 to 5 weeks, 10 sessions following exercises prompted by the SynPhNe system will be done unsupervised at home (or under limited supervision at the hospital), 2 sessions will be done at Spaulding Rehabilitation Hospital to review exercises with the SynPhNe system. |
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.

| Active Comparator: Conventional therapy Subjects will be asked to participate in a program of 18 upper-extremity rehabilitation sessions of 60 minutes under therapist supervision over two weeks at the Motion Analysis Laboratory at Spaulding Rehabilitation Hospital. The sessions will emphasize on the wrist and fingers movements, including functional activities. During week the two first weeks, 6 sessions will be done under therapist supervision at the Motion Analysis Laboratory at Spaulding Rehabilitation Hospital. The remaining 10 sessions will be done unsupervised at home, over approximately 4 weeks, and following the therapist home treatment plan. Over that time, 2 visits to Spaulding Rehabilitation will be made to review home treatment plan. Over the course of the study, participants will wear GeneActiv sensors to gather information about upper-extremity usage. |
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 Measures
Primary Outcome Measures
- Fugl-Meyer Upper Extremity [Changes from baseline Fugl-Meyer scores at 7 weeks and at one month follow-up]
FM-UE is a measure of upper-extremity motor impairment including coordination and speed.
- Box and Block test [Changes from baseline scores at 7 week and at one month follow-up]
Gross motor manual dexterity assessment
- Wolf Motor Function Test (Upper Extremity) [Changes from baseline scores at Baseline, at 7 weeks and at one month follow-up]
of 17 items that are upper extremity motor tasks and that can assess movement components required for daily tasks.
Secondary Outcome Measures
- Jamar dynamometer [Changes from baseline scores at Baseline, at 7 weeks and at one month follow-up]
Hand grip strength
- Visual Analogue Scale for Pain [Changes from baseline scores at Baseline, at 7 weeks and at one month follow-up]
Assessment of pain intensity from 0 (no pain) to 10 (worse pain experienced)
- Modified Ashworth Scale [Changes from baseline scores at Baseline, at 7 weeks and at one month follow-up]
Measure of spasticity of Upper Extremity, score range from 0 (no spasticity) to 4 (Passive movement no possible)
- Systolic and Diastolic Blood Pressure [Changes from baseline scores at Baseline, at 7 weeks and at one month follow-up]
