ROM & Below the Knee Amputees

At Joint Active Systems our goal is to help patients regain their range of motion. Below the knee amputees commonly develop contractures after surgery. Many times the residual limb length is very short, making it difficult to capture with traditional cuffing methods. This also makes it hard to obtain enough torque to properly stretch the joint.

Regaining ROM is critical for amputees to walk properly in a prosthesis. Thankfully, with the help of our Orthotist & Prosthetist and our Design Engineer, JAS has the ability to customize devices to meet the needs of our patients. In this situation, the amputee had been supplied with a locking pin prosthetic liner. This type of liner is used inside the prosthesis to function as a cushioned interface and a means to attach the prosthesis to the patient’s residual limb. Our engineer designed the device modifications with components made at our facility in Effingham, Illinois.   

We were able to send the patient an attachment for their JAS knee device that secures directly to the pin at the base of the liner. The attachment allows for better leverage and higher torque to stretch the joint. At JAS, we are passionate about creating ROM solutions for all our patients. It was a pleasure to bring this idea to life.
