An M-Health Algorithmic Approach to Identify and Assess Physiotherapy Exercises in Real Time
This addresses the need for remote physiotherapy supervision in m-health applications, but it is incremental as it builds on existing pose-estimation and sequence-matching techniques.
The paper tackles the problem of real-time identification and assessment of physiotherapy exercises using mobile devices, achieving effective performance with a system that operates on the client side for scalability.
This work presents an efficient algorithmic framework for real-time identification, classification, and evaluation of human physiotherapy exercises using mobile devices. The proposed method interprets a kinetic movement as a sequence of static poses, which are estimated from camera input using a pose-estimation neural network. Extracted body keypoints are transformed into trigonometric angle-based features and classified with lightweight supervised models to generate frame-level pose predictions and accuracy scores. To recognize full exercise movements and detect deviations from prescribed patterns, we employ a dynamic-programming scheme based on a modified Levenshtein distance algorithm, enabling robust sequence matching and localization of inaccuracies. The system operates entirely on the client side, ensuring scalability and real-time performance. Experimental evaluation demonstrates the effectiveness of the methodology and highlights its applicability to remote physiotherapy supervision and m-health applications.
