The JAS SPS Knee offers Range of Motion (ROM) therapy from 160° flexion to 21° hyperextension in a new, light-weight design. A patented motion tower, combined with infinitely adjustable ROM, assures precise end-range stretch throughout the entire treatment session. Maximal Total End Range Time (TERT) is achieved for optimal therapeutic benefit.

The JAS SPS Knee has been designed with a new, lower leg stabilizer. The new pivot point above the calf allows the cuff to remain flush with the tibia as the knee angle changes through the trange of mtion, helping to eliminate point loading. Contoured cuffing system optimizes fit, comfort and product performance.
