Summary

The goal of the study is to confirm the idea of AI-powered Technological Surrogate Physiotherapist (TSP), by demonstrating its effectiveness and value as a new technology-based contribution to OA healthcare. Participants will be randomized to one of two groups: (1) the conventional PT group receiving the exercise program delivered through in-person sessions; or (2) the AI-guided group following the program through the TSP after an initial PT session. All individuals will take part in the study for 12 weeks, and data will be collected at baseline and 12 weeks after randomization.

DEVICE

The AI-powered Technological Surrogate Physiotherapist

The AI-powered Technological Surrogate Physiotherapist will have three key features: 1. Evidence-based exercise videos instructed by physical therapists 2. Real-time movement feedback and performance score 3. Exercise records.

BEHAVIORAL

Face-to-face physiotherapist-supervised exercise program

Physiotherapists will give usual face-to-face therapy. The assessment of participants' exercise movements will only be achieved in the traditional manner during face-to-face exercise sessions - by physiotherapists' visual inspection of and professional judgement on postural alignment and effectiveness, with verbal instructions for posture correction. The features of real-time movement feedback and tracking of exercise progress will not be provided.
