Intended Use

The NeuX NXPRO Neuromuscular Electrical Stimulation Device is intended for the stimulation of healthy muscles in order to improve or facilitate muscle performance. The NeuX NXPRO is not intended to be used in conjunction with therapy or treatment of medical diseases or medical conditions of any kind. The NeuX NXPRO is not designed for use on injured or ailing muscles and its use on such muscles is contraindicated. The NeuX NXPRO's electrical impulses allow triggering action potential on motor neurons of motor nerves (excitations). These excitations of motor neurons are transmitted to the muscle fibers via the motor endplate where they generate mechanical muscle fiber responses that correspond to muscle work. Depending on the parameters of the electrical impulses (pulse frequency, duration of contraction, duration of rest, & total session duration), different types of muscle work can be imposed on the stimulated muscles. The various types of muscle work that the NeuX NXPRPO can impose on the stimulated muscles are able to improve or facilitate muscle performance. The NeuX NXPRO is considered a technique of muscle training.

Device Story

NXPRO is a neuromuscular electrical stimulation (NMES) device; delivers electrical impulses via electrodes to motor nerves to trigger action potentials; generates mechanical muscle fiber responses corresponding to muscle work. Device parameters (pulse frequency, contraction/rest duration, session duration) allow varied muscle training techniques. Operated by user/clinician; used for muscle performance improvement. Output consists of continuous medium-amplitude sensory waveform with periodic high-amplitude rectangular stimulation pulses. Transformer isolation ensures no DC output.

## Principles of Operation

The principle of electrostimulation is to stimulate nerve fibers by means of electrical impulses transmitted by electrodes. Neuromuscular Electrical Stimulation (NMES) is applied to the muscles and specifically targets the motor nerve with electrical pulses that can activate the junction between the nerves and muscles being treated and produce a contraction of the muscle fibers. A stimulation-induced contraction can give an effective workout for the muscle. The electrical pulses generated by the NXPRO stimulator are high quality pulses - offering safety, 510(k) Summary (NeuX – NXPRO Device)
