A quantitative device for elbow joint function rehabilitation based on the concept of traditional Chinese fracture rehabilitation

Early rehabilitation exercises after elbow fracture treatment can affect the degree of joint function recovery. Due to the different levels of endurance and pain tolerance of patients, blind training not only makes patients to suffer pain, but also tends to cause postoperative complications. Therefore, this paper introduces a wearable assistive elbow rehabilitation training device that can quantify the patient's recovery level. The device uses pressure sensors to collect the pressure value of the patient's arm when squeezing the muscles, tri-axial gyroscopes and tri-axial accelerometers to perceive the angular velocity and acceleration of the patient's arm during the rehabilitation exercise. The collected data are processed by an internal processor and presented in a touch screen, which in turn provides a reference for the physician to develop a rehabilitation training program. In addition, the device also provides voice alerts when the patient's rehabilitation training reaches an unreasonable level or range of motion, helping the patient to carry out quantized rehabilitation training and promote normal fracture healing.
