The NEUBIE is a unique NMES device for several reasons. It uses pulsed direct current (DC) as opposed to alternating current (AC); it has unique effects on the body’s tissues to promote healing; and it has unique effects on the nervous system that, when combined with the NeuFit System, allows practitioners to provide a meaningful dose of neuromuscular re-education.
Using DC is important, because it has numerous, positive biological effects. DC fields have been shown to accelerate the body’s own physiological processes of healing, repair, and regeneration,(31-36) and to have unique effects on the nervous/neuromuscular system.(36-39) Although this has been known for a long time, most devices out there are alternating current (AC). These devices are cheaper and easier to engineer, and most people don’t know the difference. Unfortunately, they won’t have anywhere near the same effect at the cellular level.
The Neubie’s DC technology enables practitioners to use an “input-based” approach to rehab and training: sending inputs into tissue that can influence the body’s outputs and responses to stimuli. The unidirectional flow of DC fields is able to achieve more input stimulation to sensory afferent signaling compared to the bidirectional flow of AC, which can cause a co-contraction that suggests both input and output stimulation to the nervous system.
Further, DC allows for more specific contractile movement at higher amplitudes, making it more useful and efficient for training and rehabilitation. DC has a longer phase duration than AC, requiring less intensity (amplitude) to evoke an action potential. Additionally, activation of denervated muscles requires a longer pulse length, achievable with DC(40) but not with AC.
In the past, the power of DC devices has been limited, as DC fields can cause charge build up that leads to skin irritation. But the Neubie beats the build up by including an additional waveform that dissipates heat and charge buildup, allowing for higher intensity stimulation without irritation!
