There has been an observed decrease in motor and functional ability and non-use of the impaired limb in chronic patients. This is due to the immediate drop in intensive daily therapy (5 days per week for 3 hours/day) that is usually provided during the inpatient (acute) phase upon discharge from the hospital.

In this study, the investigators plan to address the low dosage of therapy in the post-acute discharge phase for stroke survivors.

Current models of care in public healthcare institutions (PHI) cannot provide daily or frequent access to RAT without increasing burden and expenditure in direct healthcare resources. Shifting from the existing hospital-based model of care towards a home-centered model based deploying portable RAT, would ensure that patients can continue to receive intensive therapy after discharge and during the chronic phase of stroke.

More recently, RAT deploying table-top, portable, less complex, upper limb end effectors enable clinic-to-home transitions may offer decentralized therapy, minimally supervised by therapists as a potential means to bridge various gaps in access to RAT such as scheduling, physical or social barriers, distances and hospital lockdowns related to viral pandemics.

This study aims to explore the utilization, feasibility and acceptability using a multi-cluster deployment and adoption of a decentralised robot-aided telerehabilitation (RATR) clinical programme supported by AI-enabled platform, with remote monitoring by clinic therapists
