 2. How tens work?

 TENS works by passing harmless electrical signals into the body from its pads. This relieves pain in two ways:

   Firstly, "high frequency" continuous, mild, electrical activity may block the pain signal travelling to the brain.      Brain cells perceive pain.
  Secondly, TENS stimulates the body release its own natural pain-control mechanism. "Low frequency" or short bursts of mild, electrical activity may cause the body to release its own pain easers, called beta endorphins.

       Pads can be used for 30-40 times at home, it depends on different situations. In hospital, they can only be used for not more than 10 times.
  (3)What should we do if there is discomfort when putting the pads in the shoulder?
       It all depends on the personal body. Therefore, the user should begin to use it from the lowest strength and speed to increase step by step to reach a better status.
  (4) What should we do if there is no function during using?
       A. Someone may feel stressed for the first using. If this feeling lasts exceeding one minute, please move the pads a little. Sometimes, indirect stimulation will affect sensitive position of the body.
      B. Check the battery if there is any need to change the battery or charge the battery.
      C. Check the pads carefully. If the pads become soiled or dirty, the adhesive power may decrease. In this case, moisten the surface of the pads with water and wipe away the dirty portion (do not wash them with water directly, oil and soap). This will allow a temporary restoration of the adhesive power. However, too much water will result in loss of the adhesive power.
