The placement of needles in specific acupuncture points can relieve the pain through different mechanisms. First, the acupuncture can reduce muscle spasms hen applied in trigger-points. The lack of spasms increases the comfort considerably.

The acupuncture can also induce the liberation of a variety neurotransmitters that can affect the processing of the painful pulse. That effect can be intensified being used specific types of electric stimulation. The appropriate placement of the needles and the electric stimulation of low frequency (2 to 6 Hz) they induce the central liberation of endorfinas that can induce the analgesia by the inhibition of the transmission of pulses noxious of his origin for the brain and of the increase of the descending inhibition of turn to the periphery. That stimulation type usually produces analgesia in 10 to 20 minutes and it is considered cumulative, meaning that the subsequent treatments produce analgesia well and better.
The electric stimulation of high frequency (100 to 200 Hz) it induces the adrenaline and noradrenaline liberation, also promoting cumulative analgesia.
