Joint Active Systems (JAS) is the innovator and market leader for adjunctive range of motion therapy. JAS provides a complete array of Range of Motion Therapy treatment options – Static Progressive Stretch, Dynamic Splinting, and Custom Turnbuckle Orthoses – to meet the unique needs of each individual patient. Since its inception in 1992, JAS has helped to successfully restore joint ROM for over 350,000 patients worldwide. With unequaled design technology JAS moves beyond convention to assure the best results for patients challenged with range of motion loss.

The Best Choice For ROM Therapy – JAS Has You Covered

Static Progressive Stretch (SPS) and Dynamic Splinting are fundamental and proven treatment approaches for permanently stretching shortened joint tissues, to restore ROM and function for patients following injury, surgery, or disease.  SPS and Dynamic Splinting are the precise stretching techniques used by therapists when providing hands–on ROM therapy in the clinic. It makes best sense to send patients home with the same stretch protocol used by professionally trained therapists. By offering the full spectrum of ROM therapy options with our complete lines of JAS SPS, JAS EZ Turnbuckle, international market JAS GL, JAS Dynamic, and Advance Dynamic splints, JAS is your single source provider for fast and effective joint motion recovery.

THE Single Source Provider for Fast and Effective Joint Motion Recovery

JAS, the pioneers and innovators of static progressive stretch technology, now offer a complete spectrum of SPS, Dynamic and Orthotics that provide ROM recovery solutions used by clinically trained therapists. Drawing from our extensive and complete lines of JAS SPS, JAS EZ Turnbuckle, international market JAS GL, JAS Dynamic and Advance Dynamic splints, JAS is THE single source provider for fast and effective joint motion recovery.

Discover the World of JAS

JAS SPS is the original SPS care option from the ROM Specialists. With our signature Motion Tower™ offset fulcrum geometry that Unloads the Joint™ patients can be assured of an effective, pain-free, self-directed stretch that helps meet their ROM goals. Our JAS EZ Turnbuckle provides the quality of JAS SPS in a single-patient solution through advanced turnbuckle design. Our patented Motion Arc™ technology brings the JAS offset fulcrum design to individual patients from physicians who direct their therapy with the best ROM goals in mind. JAS GL, featuring ruggedized construction, was designed and built for the demands of multiple patient usage in international healthcare markets. JAS Dynamic was introduced to provide the marketplace with full-range, dynamic Range of Motion therapy in an effective, offset-fulcrum design; coupling all the advantages of dynamic therapy to our JAS SPS line. Finally, Advance Dynamic splints are a low-profile, lightweight design to make dynamic ROM therapy easy and accessible for the single patient marketplace.

Unequaled Patient Compliance

No matter what the protocol or device, for any home therapy program to be effective, patients must be compliant! All JAS devices are designed to be easy to apply, comfortable to wear, and simple to use, to maximize patient compliance. JAS device technology enables total patient control of their ROM therapy; when patients can control the intensity of stretch, muscle guarding and pain are virtually eliminated.  A variety of time efficient JAS treatment protocols have been proven effective in peer-reviewed literature, and show unequaled patient compliance. Patient compliance directly equates to better results and successful rehab outcomes.

Different By Design™

Move beyond convention.

ROM systems from JAS comfortably stretch your patients beyond what’s possible with the competition. The key to success is in product design. With patented Motion Tower and Motion Arm technology, JAS, JAS EZ, international market JAS GL, and JAS Dynamic are the ONLY product lines that “unload the joint” – reducing painful joint surface loading during use. JAS geometry applies soft tissue distraction and stretch loads 90° to the extremity through the entire range of motion. JAS systems deliver pain free, patient-directed ROM therapy through a greater arc of motion than any other brand of stretch device. Move beyond the competition and see the proven outcomes achievable with JAS SPS, JAS EZ, international market JAS GL, JAS Dynamic and Advance Dynamic.

Joint Force – Biomechanics

The Right Features

The most effective treatment method for restoring joint mobility is manual therapy, including soft tissue distraction, applied by the skilled therapist. JAS’s unique geometry mimics the stretch techniques and soft tissue distraction forces that therapists apply, for optimal results. First, JAS device geometry displaces the stretching force away from the joint surface, which minimizes joint compression and maximizes mechanical stretch forces to the tissues. The stretching force is also applied ninety degrees to the extremity while it correctly follows the anatomical arc of motion of the joint. Second, the JAS design includes “Single Plane Positioning,” which virtually eliminates joint malalignment during treatment. This design assures the patients’ joint is aligned in a single plane with the JAS Motion Tower™ or JAS Motion Arc™ throughout the entire arc of motion.

In contrast, competitive products are designed with the device fulcrum aligned directly across the joint axis to stretch the extremity, compressing the joint and articular cartilage. These compressive loads coupled with malalignment increase risk for the patient to experience discomfort and pain. Discomfort and pain result in poor patient compliance!

30+ peer-reviewed studies definitively show that JAS SPS therapy providing Low Load Stretching Forces are effective at restoring ROM in a wide variety of conditions, including knee arthrofibrosis. These studies absolutely disprove claims that effective therapy for stiff and fibrotic joints can only be achieved with high torque, short duration stretch devices. JAS products provide safe and effective ROM restoration for all levels of joint stiffness.
