As the world’s only system that can display real-time changes in muscle strength throughout the body, Karen can use the data transmitted by various hardware and sensors to perform real-time analysis and calculations so that patients can see real-time changes in the muscle strength of each of their muscles, and can also clearly know which of their muscles are exerting force and which muscles are not exerting enough force through color changes, and ultimately achieve the desired goal through proprioceptive adjustments.
