Sensors Based Wearable Device for Hemophilia Patients in Programmed Sports Therapy

Abstract

Hemophilia is a genetic disorder where internal bleeding occurs at the joints like knee, ankle, elbow, shoulder, hip etc. This internal bleeding is due to a defect in clotting factors. Tibio-femoral joint is more prone to the disorder. Total knee replacement is a safe and proven surgical procedure for hemophiliacs. After the surgery, the ‘World Federation of Hemophilia’ suggests a programmed sports therapy. The exercises are done once after the bleeding have stopped. If any bleed occurs during therapy, the exercise must be stopped as it induces infection. As a result, deformity and stiffness occur in muscles. Due to stiffness, the patient’s position is so that he applies more force on the toes. An improved wearable device is proposed which will measure the range of bending in knee joint, measure the force applied at the toes against the ground and measure the position of the joint while the person does the sports therapy exercises. The proposed work will inform the change in positions and related measurements to physician’s mobile phone via IoT. With this proposed wearable device, the physician could monitor the patient’s status from any place with the help of the internet. The usage of the proposed device in the knee joint will eradicate 97.6% of issues faced by the Hemophilia patients as they are unaware of the bleeding condition because of their wrong positions.
