How the NeuroTrac® MyoPlus 4 Pro-MYO440PWorks

The NeuroTrac® MyoPlus 4 Pro is a dual-channel EMG, ETS, and four-channel neuromuscular stimulation device designed for assessment and rehabilitation. Channels 1 and 2 measure EMG activity or deliver stimulation, while Channels 3 and 4 provide stimulation only. In EMG mode, the device measures muscle activity in microvolts and provides visual and audio biofeedback to guide voluntary contractions and relaxation. Users can follow work and rest prompts, track performance, and review detailed statistics. The touchscreen interface allows easy program selection, parameter adjustment, and access to preset or customized protocols.

The device also delivers NMES, TENS, and ETS. In ETS, voluntary contraction above a set EMG threshold triggers stimulation to support muscle effort. Programs can include multiple phases such as continuous, synchronized, alternating, or modulated stimulation. Adjustable parameters include frequency, pulse width, intensity (mA), ramp times, and work/rest cycles.
