Isokinetic resistance mode

 The Isokinetic Resistance mode for testing and rehabilitation is totally accommodating throughout the entire range of motion. Biodex’s unique impact-free acceleration and deceleration eliminates joint trauma, allowing patients to exercise and be tested at more functional speeds. Resistance continuously matches effort, accommodating to variations in patient force output due to weakness, pain or fatigue at specific points in the individual’s range of motion.

Research along with over 30 years of clinical application has demonstrated that isokinetic resistance is a safe, objective means to quantify physical impairments with a high correlation to function. Isokinetic testing is the standard for muscle and joint assessment.

Applied torque response ensures that the patient’s limb velocity increases or decreases in proportion to the torque applied during acceleration and deceleration, enabling neuromuscular control measurements.

Choose concentric and eccentric contractions to perform isolated polymetric exercises.

Concentric torque up to 500 ft-lb (680 Nm) and eccentric torque up to 400 ft-lb (542 Nm) accommodates the demands of high performance athletes and sports medicine researchers.

Reactive eccentric mode

 The Reactive Eccentric mode for submaximal neuromuscular re-education in the early phases of rehabilitation. The System 4 responds only to the patient’s force output. To initiate movement, the patient must produce and maintain a pre-determined minimum amount of force. This loads the muscles surrounding the joint, producing a pre- load, thus stabilizing and protecting the joint. Eccentric torque up to 400 ft-lb (542 Nm). Accommodates the demands of today’s athletes and sports medicine researchers.

Passive motion mode

The Passive Motion mode is a multi-function modality. Unique control properties allow for early intervention in all patients throughout all phases of rehabilitation.

Torque limits can be set as low as .5 ft-lb (.7 Nm). If a torque limit is exceeded during an eccentric contraction, the System stops. Once the patient’s torque output drops below the prescribed limit, movement is allowed. This unique capability allows patients to work safely at definitively prescribed sub-maximal force levels while combining isometric, concentric and eccentric contractions for:

  • decreasing joint effusion

  • increasing range of motion

  • developing strength

Passive speeds can be set as low as .25 degree per second and as fast as 300 degrees per second. The very slow speeds allow for overcoming the natural stretch reflex. Biodex software includes specific protocols for active and passive joint repositioning. Higher speeds in passive mode are ideal for active assistive exercise.

Isometric mode

 The Isometric mode is commonly used pre and post operatively or when pain associated with motion is a factor. Isometric contractions are effective at developing strength and decreasing joint effusion while avoiding painful points in the range of motion.

Biodex software automates the rehab process with automated multiple angle isometric protocols. Work the agonist, antagonist or both muscles at specified joint angles.

Isotonic mode

     The Isotonic mode allows velocity to vary while providing inertia-free constant force and concentric or eccentric muscular contractions.

    Higher performance:

    • Isotonic force to as low as .5 ft-lb (.7 Nm) = 6 inch pound; and as high as 400 ft-lb (542 Nm). 

    • Allows for functional task simulation when using work simulation tools, e.g. turning a doorknob.

    • Because the force is selected, the Isotonic mode also provides protective pre-loading of the joint prior to movement.

    Ideal for work simulation. Constant force muscle loading is considered functional, as natural activities normally involve moving a constant weight object at varying velocities.

    Pediatric medicine

     Used to treat children worldwide, Isokinetic muscle testing helps clinicians by providing objective data for neuromuscular control and strength. Pediatric attachments and age-based normative data are available. View normative data for quadriceps and hamstrings in children ages 6-13 years.

    Sports and Orthopedic Medicine 

     Whether your orthopedic and sports medicine practice is allowed only limited visits or you have the luxury of managing a complete recovery, Biodex is the tool that adapts to every environment. Evidence-based clinical protocols combine science with practical application to ensure that you provide the best outcomes.

    Hamstring injury, anterior cruciate ligament (ACL) injury, osteoarthritis of the knee, lateral ankle sprains, patella-femoral dysfunction. Other abilities include pre-season screening, injury prevention, and improving athletic performance.

    Older adult

     Biodex Fall Risk Screening & Condtioning Program has been employed by leading clinics for more than ten years. It is the only fall program that incorporates a complete array of objective tests. Isokinetic testing will identify weakness; exercise will improve ankle and leg strength.


    Neurorehabilitation

     For the management of persons with movement disorders, neurologic pathologies, or general deconditioning; an Integrated Protocol Using Instrument. The system helps patients build strength, endurance and coordination. Spasticity management includes objective quantification at specific contraction. Use Passive mode for repetitive exercises. Eccentric mode is useful for controlled strengthening. Upper extremity attachments for hemiparetic patients.
