AR Training Platform at Home

Study Overview
=================
Brief Summary
-----------------
Video Communications, like ZOOM, have been widely used in the time of this epidemic. But how about to design an AR / VR communication system with coaching from clinician to facilitate training at home in this time of epidemic. Vulnerable individuals at home can interact with the training platform and his/her clinician can provide online training progamme with guidance.

Design Details

Primary Purpose: Treatment
Intervention Model: Single Group Assignment
Masking: None (Open Label)


Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Experimental: AR Training System<br>The subjects follow the daily rehabilitation training program designed by clinical and healthcare team. The system will monitor their movement and provide feedbacks to the users. The clinicians/healthcare workers can provide feedbacks and guidance to correct their movements and postures. | Device: An Online Augmented Reality (AR) Training Platform<br>* The hardware system is based on camera depth sensor and combined with 3D human tracking technology and intelligent technology, to monitor, correct and record the user's whole body movements in real-time, and the users can follow the training program.<br>|

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

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Fugl-Meyer Assessment | Fugl-Meyer Assessment for Upper-Extremity the maximum score is 66, divided into 33 items in the form of a 3-point scale (0-2), 0 is cannot perform and 2 performs fully. Fugl-Meyer Assessment for Lower-Extremity consists of 34-level cumulative scoring system to examine lower-limb functions of hemiplegic stroke patients quantitatively through a set of lower-limb movement tasks in reflex, flexor/extensor synergy, volitional movement, coordination and speed (Fugl-Meyer, et al., 1975). | 6-month after the first training | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| The 12-item Short Form Survey | It is a self-reported outcome measure assessing the impact of health on an individual's everyday life. It is often used as a quality-of-life measure. | 6-month after the first training | 
| Barthel Index | It assesses functional independence, generally in stroke patients. | 6-month after the first training | 
| Berg Balance Scale | Berg Balance Scale (BBS), consists of 56-level measures to examine balance ability and to predict falling risk with high reliability (ICC=0.98) (Steffen, Hacker & Mollinger, 2002). Stroke patients were assessed based on their performance on 14 simple mobility tasks, including transfer, standing, and reaching | 6-month after the first training | 
| Modified Ashworth Scale | Modified Ashworth Scale (MAS), consists of 4-level scale to examine joint spasticity based on muscle tone and resistance detected during passive stretching with good inter-rater reliability (ICC =0.85) (Bohannon & Smith, 1987). | 6-month after the first training | 
| Functional Ambulation Category Test | Functional Ambulatory Category (FAC) is a reliable measurement of independent walking ability on level-ground walking and stair ambulation, which is a good prediction of independent community walking post-stroke (Mehrholz, et al., 2007). FAC consists of 6-level scale: patients with FAC=4 requires supervision in level ground walking, FAC=5 requires supervision only when walking on non-level surface such as stairs. | 6-month after the first training |
