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
occurs.
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.
12 TECHNICAL
DATA
The TensMed S84 is a four channel stimulator for both muscle rehabilitation (NMES) and pain
relief (TENS) and features 107 preset programs and 15 custom programs.
Treatment with electrical stimulation requires the stimulation current to penetrate the resistance of
the skin and the electrode, about 1000 ohms. The TensMed’s can penetrate this resistance and
maintain a current of up to 99.5 mA. With a change in load from 100 to 1000 ohms, the stimulation
current changes less than 10% from the set value.
The stimulator operates on a rechargeable battery pack, rechargeable with the adapter.
