The method of reducing pain in a patient by combining a traditional pharmacological treatment with electro-acupuncture or percutaneous electrical nerve stimulation therapy. The pharmacological treatment consists of using analgesics such as morphine sulfate and hydromorphine provided to patients around the clock or as needed for pain. The patient controlled analgesia pump (PCA) is used by patients for self-administering of analgesia as needed. After patient stops using PCA pump narcotic and non-narcotic pain medications are administered mostly orally. Typically, there are two pairs of needle electrodes, two on each leg, connected to two separate outputs of the portable electrical stimulator. The constructions of the needle holder and the stimulator allow a patient to move freely and, if necessary, to carry the device during the entire day.

The present invention is directed to transcutaneous electrical nerve stimulation (TENS) devices which utilize novel stimulation waveforms and novel arrangements of TENS electrodes to improve the efficiency of power consumption while enhancing therapeutic effects.

The invention discloses a constant current type transcutaneous nerve electrical stimulation circuit comprising a microcontroller, a power supply circuit, an indication circuit, an output circuit and amotion detection circuit. The microcontroller is electrically connected with the power supply circuit, the indication circuit, the output circuit and the motion detection circuit; the output circuitis connected with a stimulation electrode; the stimulation electrode is provided with the motion detection circuit; and the output terminal of the motion detection circuit is connected with the microcontroller. The invention employs a percutaneous positioning method and belongs to a non-invasive positioning technology. After positioning to the nerve, acousto-optic indication can be made to avoid unnecessary trauma to the human tissue, so that objective evaluation of nerve positioning is realized. With the motion detection technology, the stimulation current output can be flexibly adjusted according to the motion conditions of corresponding muscle groups, so that accurate and controllable constant-current stimulation on tissue is realized.
