Telerehabilitation Platform for Post-Arthroplasty Recovery: A Dynamic Time Warping Approach

Abstract:

This study presents key features to develop an efficient tele-rehabilitation platform to support the recovery process in patients after hip replacement surgery. The tool is designed on the concepts of therapeutic education and serious games, in order to enhance the self-rehabilitation. Also, the system is built on a modular architecture to ensure its scalability and adaptation to other physical therapeutic programs. The assessment module integrated in the platform and implemented in dynamic time warping allows for a fair discrimination of the quality of the exercises performed by the users, especially when the motion acquisition is not affected by occlusion. An important contribution of this work is to propose a method that can assess both the range of motion and the compensation movements that may be involved in each exercise.
