HOW DO I FIND THE OPTIMAL POSITION OF THE ELECTRODES FOR NMES?
Use carbon rubber electrodes and gel. Slide the electrodes slowly over the muscle while stimulating at 2
Hz. The optimal position for the electrodes is where the strongest motor response occur.
FOR HOW LONG CAN I STIMULATE?
TENS (80 Hz): Can be used without an upper limit, but at least 30 min at each occasion.
TENS (2 Hz): Can cause sore muscles but normally 20–45 min three times a day is recommended.
NMES: Depending on the muscle's status and where the patient is in the rehabilitation process,
treatment can last from 5 to 60 minutes and be repeated from three times a week to twice a day.
Remember that the patient may develop sore muscles after NMES treatment.
