Electrical Stimulators is interferential, premoditated, high volt waveforms, and lightweight for use. It has clear LCD display. Waterproof membrane overlays for easy selection of waveform and parameter control. It has ability to store start-up parameters. It combines all the advanced technology of the Intelect Legend Stim with the Intelect Legend Ultrasound. It provides one of the cleanest views of muscle adaptation to increased use. This model is used to study skeletal muscle adaptation since it induces a repeatable, quantifiable amount of exercise. It is used for suprafusion systems and stand-alone use. It is fully programmable, and offer a choice of either mono or biphasic current output. Each channel is individually regulated and adjustable. Front screen displays bar graph for output of all channels at once, or digital scope of any single channel. It consists of a pocket-sized main unit, a foot switch and two adhesive surface electrodes connected with wires. The electrical stimulation might cause a slight tingling sensation.
