The Prediction and Evaluation of Strength and Fatigue to Prevent Warfighter Musculoskeletal Injuries
Musculoskeletal disorders are common for people who work on strenuous and demanding tasks, such as nurses, construction workers, and soldiers. The injuries come from overexertion of the individual's related muscle groups that are required to be activated to complete a specific task in various environments. A current solution is the use of robotic-aid devices. These robotic devices are being investigated to treat musculoskeletal injuries and significantly increase a human's capacity in heavy working conditions. However, the design of the human-machine interaction force remains an obstacle to the implementation of effective assistance to people in practical working scenarios due to the environmental variety, task complexity, and human variation and uncertainty. Previous studies showed that the metabolic cost of exercise will be increased instead of reduced if improper forces are provided by the machine. Thus, accurate estimations of the required machine force application to the individual are critical to labor saving and muscle health.
