The The ERGYS 3 Rehabilitation System is Therapeutic Alliances' fourth generation CFES (computerized functional electrical stimulation) ergometer, following the groundbreaking technological innovations of the REGYS and the ERGYS 1 & 2 ergometers. This family of FES leg-cycle ergometers provides the means for the neurologically impaired individual to stay as healthy as possible using a combination of FES-induced muscle contractions and well-proven therapeutic rehabilitation techniques.

The ERGYS Rehabilitation System uses computerized functional electrical stimulation (CFES) to allow persons with little or no voluntary leg movement (e.g., SCI) to actively pedal a stationary leg-cycle ergometer. Computer generated, low-level electrical pulses transmitted through surface electrodes cause coordinated contractions of the large muscles of the legs. Sensors located in the ERGYS provide continuous feedback to a computer which controls the sequence of muscle contractions as well as the resistance to pedaling. The result is smooth and natural pedaling, with the rider’s leg muscles supplying the power. The benefits to this therapy include the prevention of muscle disuse atrophy, relaxation of muscle spasms, improved circulation, and increased range of motion. Clinical studies have also documented improvements to the cardiovascular system as well as other systemic benefits.

The ERGYS Physician Electronic Prescription Station (PEPS) allows the physician and clinician to safely control and monitor patient sessions on the ERGYS Rehabilitation System. Limits to the therapy can be programed on the Data Token to ensure that parameters such as workload and stimulus levels cannot be set to inappropriate levels. Session information is stored back to the Data Token for review at the PEPS.


The REGYS Clinic Rehabilitation System was introduced in 1984. It was the first commercially available leg-cycle ergometer to use functional electrical stimulation (FES) as a means to improve the health of persons with spinal cord injuries. The REGYS, which is the predecessor of the ERGYS and ERGYS 2 Rehabilitation Systems, is still actively used in rehab and research centers around the world.  Therapeutic Alliances continues to support this product in full with service and accessories.


The NeuroEDUCATOR Electromyography (EMG) Biofeedback System is designed for neuromuscular therapy aimed at returning or improving voluntary muscle control. Through visual and audio feedback, the patient learns how to reproduce, maintain, and control EMG responses for maximum improvement in muscle function. The NeuroEDUCATOR is used by physicians, physical therapists, occupational therapists, psychologists, and psychiatrists to treat stroke, head trauma, spinal cord injury, cerebral palsy, and other neuromuscular disorders.

Four channels of powerful, portable electrical stimulation to retain muscle mass and improve overall health. A great complement to the ERGYS.
