AR Training Platform at Home

Not Applicable

Recruiting

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.

Arm && Interventions

Group	Intervention	Description
AR Training System	An Online Augmented Reality (AR) Training Platform	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.

Primary Outcome Measures

Name	Time	Method
Fugl-Meyer Assessment	6-month after the first training	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).

Secondary Outcome Measures

Name	Time	Method
The 12-item Short Form Survey	6-month after the first training	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.
Modified Ashworth Scale	6-month after the first training	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).
Berg Balance Scale	6-month after the first training	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
Functional Ambulation Category Test	6-month after the first training	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.
Barthel Index	6-month after the first training	It assesses functional independence, generally in stroke patients.
