The external currents with different frequencies are considered to cause different effects in tissues. Thus we assume that tissue reactions on different frequencies in different states of the body will also differ from each other.
Measuring the sensory, motor and pain thresholds by stimulating the tissue with the interference current may offer a diagnostic tool in physiotherapy and rehabilitation
Wound tissue is (+) & skin around is (-); this difference is the “skin battery” or “current of injury” and must exist for proper healing; if it fails or is disrupted, then slow/no healing can occur. E -stim can help restore the “skin battery”.
Further supported by evidence that many chronic wounds lost (+) polarity; e-stim w/ the anode (+) over the wound enhanced healing. (using DC)
If healing plateaued, switching polarity = good outcome
