Stroke is the second most common cause of death and a leading cause of disability in the world.[1] Timely and adequate rehabilitation is critical in facilitating post-stroke recovery.[2] With an ageing population and the increasing prevalence of stroke, there is strong and rising demand for rehabilitation services globally.[3] However, organising and delivering rehabilitation are resource-demanding, and currently only approximately 25% of stroke survivors in low- and middle-income countries have access to such services.[4] Improving access to stroke rehabilitation services to facilitate timely and accessible rehabilitation in the community setting is important to reduce the burden on public healthcare facilities.

Although there has been an increasing use of telemedicine and telerehabilitation services, current solutions rely heavily on subjective reporting through video conferences or phone interviews. Other solutions attempt to use various sensor- and camera-based devices to capture a stroke victim’s exercise performance, but fall short in the real-life application of home-based tele-rehabilitation, given the relatively high cost per unit and spatial requirements.
