Before applying electrode pads, be sure to wash the skin with warm soapy water to remove any dirt, oil or creams that may be present on the skin. The presence of oils and debris can degrade electrode pads and cause problems with adhesion.
Electrode placement for EMS (Electrical Muscle Stimulation) is very important for obtaining the best results. Muscle activation works best when the motor nerve is located and stimulated.
Usually the Bipolar Technique is used, in which two electrodes are placed over the bulk of the muscle - with one electrode (usually the black pin) placed over the muscle’s motor point (also used in Asymmetrical Biphasic Pulse Stimulation).
The motor point is the area on the skin that is located closest to the muscle’s motor nerves entry point. Here, it is easiest to trigger a contraction by electrical stimulation.
Localising the motor point provides the cleanest and most comfortable contractions. These points can be located by using a diagram or muscle map.
Move the electrode across the skin and locate the point over the muscle that gives the cleanest contraction. Large muscle groups may require stimulation with two channels i.e. using four electrodes simultaneously.
WARNING: Do NOT place electrodes across the chest or the front of the neck.
Electrode Pad Care
The pads which are supplied with TensCare devices are self-adhesive and can be used several times. Skin must be allowed to breathe - therefore the pads should be removed periodically. When not in use, the pads should be placed on the pad holder or returned to the clear plastic shield.
The condition of the pads does affect the conductivity and performance of the device. When the pads initially lose their adhesive quality, it is possible to reactivate their adhesiveness by applying a fine spray of water. Once the pads have finally lost their adhesive quality, replacement electrodes should be purchased.
