Development of an Exercise Application to Support Physical Function Improvement and Training for Remote Workers

We developed an exercise application to assist remote workers with physical dysfunction. 1) To determine physical dysfunction, it is necessary to objectively evaluate joint range of motion and muscle dysfunction. Twenty one employees had their standing, plank, one-leg stand, and overhead squat images captured. By using the skeletal coordinates obtained from the images, criteria for determining physical dysfunction were formulated in relation to subjective scores such as stiff shoulders and back pain. 2) On the basis of these results, we developed an exercise application in which physical dysfunction was judged in four different postures, and exercise for improvement was performed in accordance with the results, gradually increasing the intensity of exercise. Clinical Relevance— It shows the possibility of using objectively measured skeletal coordinates to assess physical stress.
