Novel limited knee flexion angle device

Knee injuries have become more common in Thailand, either caused from the sport or from the accident. The treatment is mostly a surgery. Hence, after the surgery, the patient must be closely monitored to prevent complications and repetitive injury. It also requires physical therapy to restore the knee function to resume a normal use. For this reason, the idea of creating a device that can restrict the patient's knee bend by internal mechanisms to prevent repetitive injury was brought out by measuring the flexion of the patient's knee using 3-axis Accelerometer/Gyro Module (IMU). The information is then displayed through a computer program created so that the doctor or physiotherapist can adjust the therapy to suit a particular patient individually. This will result the patient to return to normal life as quickly as possible. The device is designed by computer aided design (CAD) software and is simulated. The device has an electronic circuit that communicates with the computer wirelessly (Bluetooth) to send data to the display on the generated program. The bending angle can be displayed immediately and recorded for a diagnosis and recovery of the patient.
