Active Smart Wearable Orthosis for Enhanched Rehabilitation THErapy

Study Overview
=================
Brief Summary
-----------------
The purpose of this study is to investigate the usability of a new upper limb robot assisted therapy device in stroke patients.

Detailed Description
-----------------
The number of physically weak individuals is increasing, resulting in a higher burden on health care and health care workers. The use of robot assisted therapy (RAT) might partly solve this problem. Rehabilitation progress highly depends on training intensity and training duration, favouring the use of RAT. In this pilot study, the usability of a new upper arm RAT device for upper arm rehabilitation in stroke patients is investigated. Myo-electrical signals will serve as input for the device, assisting the user in flexion and extension of the elbow, which is combined with a stabilizing shoulder brace and a bionic glove.

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Investigate user experience by a self-composed questionnaire. | Investigate user experience by a self-composed questionnaire with theorems where upon users have to score. Possible scores range from 1 (totally disagree) to 4 (totally agree). | Up to 30 minutes at the last session | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Measure the rate of perceived exertion by the Borg scale. | Measure the rate of perceived exertion by the Borg scale. The Borg scale is a way of measuring physical activity intensity level. Possible scores range from 0 (no fatigue at all) to 10 (worst imaginable fatigue). | Up to 5 minutes at the last session | 
| Investigate whether wearing the device improves functionality by the Action Research Arm Test (ARAT). | The Action Research Arm Test (ARAT) is an evaluative measure to assess specific changes in limb function among individuals who sustained cortical damage resulting in hemiplegia. | Up to 5 weeks (at week 1, week 2 and week 5) |
