How does the SPORT EXT Rehabilitator work ?

• Dual elastic tension bands and SWING ASSIST, in conjunction with anterior and posterior air bladders, apply a correct kinematic stretch. There is a posterior-anterior glide of the proximal tibia over the distal femur as the knee joint extends.

• In a long sit or supine position, with the heel propped, it applies an extension moment to the knee join while preserving correct kinematics.

• In walking, it promotes active stretch with every step. As the leg comes from stance to the swing phase, the SWING ASSIST, in conjunction with the posterior and anterior air bladders, push the knee joint into more extension every step. This promotes quadriceps activation.

• Patients with weak quadriceps benefit by having the brace stabilize stance phase and promote knee extensions during the stance phase.

• Medial/lateral air bladders allow for improved control and eliminate brace migration. In conjunction with the anterior/posterior air bladders, the brace provides multi-planer stability.

The degree of knee extension is associated with postoperative clinical, functional and radio-graphic outcomes. Despite better understanding of the etiology of development of knee flexion contractures and their management, its prevalence can be as high as 42% to 58% in many common conditions.

Common conservative options to treat knee flexion contracture include :

• Physical therapy

• Home exercise programs

• Mechanical therapy ( splints, braces etc. )

Effectiveness of these traditional treatments is dependent on the intensity, duration and frequency. Physical therapy is often not frequent enough on of adequate duration to realize desired outcomes. Most home exercise programs are active for a short duration and not enough force is transmitted through the tight tissue. Mechanical therapy does not allow the patient to be ambulatory and does not promote active stretch.

The SPORT EXT Rehabilitator brace was developed to address all of these issues. The brace imparts adequate deforming force to the tight tissue when seated or when walking. It allows the patient to be mobile, promotes active stretch every step the patient takes and facilitates quadriceps activation. In addition, the brace also gives multi-planar stability and correct kinematic knee joint positioning through strategically placed air bladders.
