RULES FOR USE
1. POSITION OF ELECTRODES
For optimum results, use the recommended electrode positions. A dierent electrode must be connected to each end of
the cable.
N.B. Please note that for large electrodes with dual connections, connection can be made by connecting the lead to one of
the connections only.
It is important to select appropriately sized electrodes (small or large) and to position them correctl on the muscle group that
you wish to stimulate in order to ensure eective treatment. It is therefore appropriate to always use the electrode size shown
in the illustration. If necessary, try to nd the best position possible by moving the electrode on the muscle, until you locate
the point that produces the best contraction, or where the greatest comfort is found.
For TENS type programmes, the general rule is to cover the painful area with electrodes.
N.B. Approximate positioning of electrodes makes the session less eective, but is not dangerous.
2. BODY POSITION DURING STIMULATION
This position varies according to the muscle group that you wish to stimulate and the programme that you are using.
For programmes inducing powerful muscular contractions (tetanic contractions), it is recommended to stimulate the muscle
isometrically. You should therefore hold the extremities of limbs being stimulated.
This position opposes maximum resistance to movement and avoids any shortening of the muscle during contraction, which
would risk causing cramps. For example, when stimulating the quadriceps, you should be in a sitting position with ankles
isolated to avoid extending the knees.
For the other types of programmes which do not induce powerful muscular contractions but only muscular twitches or
tingling, position yourself as shown on the illustration, maintaining a comfortable position.
