When joints in the body experience trauma through injury or surgery, the central nervous system will often initiate an involuntary response in the muscles to protect the joints from further injury and promote healing. This response is called muscle guarding.

The JAS Dynamic Knee and Elbow devices are now bidirectional, allowing ROM therapy in two directions of joint motion with one device.

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. JAS has the ability to customize devices to meet the needs of these patients.

This is a question we often get from our patients when they’re deciding which device might be right for them. Our resident Orthotist & Prosthetist at JAS, Bryan King, answers it here.

This study followed 25 patients with knee stiffness following TKA. All patients had manipulation under anesthesia and a standard course of physical therapy and saw continued stiffness and unsatisfactory improvement afterwards.

JAS is highly committed to quality and patient satisfaction. In fact, we host a weekly quality assurance meeting including our Design Engineer, Licensed Orthotist/Prosthetist, Quality Assurance Director, Technical Support team, and several others to review products and services, evaluate technical support call trends, and discuss further research and development opportunities.
