Transcutaneous Electrical Nerve Stimulation (TENS), a method of stimulating nerves using electrical current applied through the skin for therapeutic purposes, has been in use since the late 1970's, as have electronic units for self-administration of TENS therapy. With the recent increase in popularity of mobile devices capable of audio playback (smart phones, portable computing devices, MP3 players etc.), most TENS users already carry consumer electronic equipment capable of providing power and control to another device via its audio port. A TENS unit designed to: (a) be coupled with an audio playback capable device, (b) make use of its power and (c) rely on it for user interaction, provides a smaller, less expensive and more convenient portable treatment solution. This approach can be extended to other electrotherapy forms utilizing similar power budgets: Microcurrent Electrical Nerve Stimulation (MENS), Percutaneous Tibial Nerve Stimulation (PTNS), Electrical Muscle Stimulation / Neuromuscular Electrical Stimulation (EMS / NMES).

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 provides a novel device for portable percutaneous electrical nerve stimulation and electro-acupuncture. In the preferred embodiment, the device consists of a needle / electrode holder that has a linear electrode / needle guide channel and a power supply channel that intersects with the needle / electrode guide channel and serves for insertion of a pin electrode from an electrical generator (PENS unit). The pin electrode will provide an electrical contact with the needle and at the same time function as means for securing the needle in a desire position in the guide channel. The needle remains straight and the extended portion thereof is kept out of contact with the patient's skin.
