Graph Convolutional Networks for Assessment of Physical Rehabilitation Exercises

Verified

Swakshar Deb, Md. Fokhrul Islam, Shafin Rahman, Sejuti Rahman

Journal: IEEE Transactions on Neural Systems and Rehabilitation EngineeringYear: 2022Citations: 73

Health professionals often prescribe patients to perform specific exercises for rehabilitation of several diseases (e.g., stroke, Parkinson, backpain). When patients perform those exercises in the absence of an expert (e.g., physicians/therapists), they cannot assess the correctness of the performan...
