Here's what most people don't know.
When your back has been in pain for years, the surface
muscles clench up to protect the area.
If you send a signal into a clenched muscle, the signal weakens and the contraction never fully lands.
That's why clinics warm the tissue before stimulation.
Neuro Belt does the same thing. Heat therapy releases
what's been clenched. Then the NMES signal goes deep
and actually reaches the muscle.
It's the step every other home device skips.
