Knee motion sensor


Knee Osteoarthritis occurs due to wear and tear, and deterioration of the soft cartilage that acts as a cushion inside the knee joint. This leads to bones in the knee rubbing against each other, causing inflammation and knee pain. Symptoms include slow movement and poor posture, impacting the patient’s daily life. Treatment options include Total Knee Arthroplasty (TKA) surgery and non-surgical approaches. However, non-surgical treatments often yield suboptimal results due to patients’ lack of understanding of the necessity and proper adherence to non-surgical treatments. Researchers have developed a knee motion detection device to monitor and improve the effectiveness of knee physical therapy. Users can operate and evaluate the effectiveness of knee physical therapy themselves and record data for physicians to develop and plan future physical therapy sessions.
