Item Description

This is a rarely used, Nikken Solitens Electro-Therapeutic compact handheld device for home use. It comes with the original box, user manual and body therapy charts. It requires 2 small round 3 volt lithium batteries (included), which are used but still working. This tens unit has been tested and does work as designed. Use of this class 2 medical device requires a prescription in the U.S. International buyers (non-U.S.) do not require a prescription. U.S. buyers will need to provide proof of prescription at purchase before you send payment. Chiropractors are also using the Solitens on their patience. This device is used to alleviate chronic pain by painless, electro-therapy positive and negative stimulation and can be used at home by yourself after carefully reading the user manual. This easy-to-use tens unit is no longer available from Nikken and highly sought after because it does not require the use of gel or pads. Original retail value is $140. Item will ship to anywhere in the U.S. for $5 or worldwide for $12. U.S. Insurance is recommended for an additional $3.

Please ask any and all questions before you purchase, so you know exactly what you are buying, as  all sales are final and there are no returns. Payments required within 4 days of purchase. I accept Paypal, U.S. money orders & cashiers checks and International money orders from a U.S. bank. No cash or personal checks are accepted.

The following information describes the history and application of this device.

Effective Therapy Device for the Relief of Aches and Pains All Over the Body

In their fight against clinical pain, healthcare professionals around the world have realized that Transcutaneous Electrical Nerve Stimulation (TENS) therapy is an effective and important component of many treatment programs. The therapeutic use of TENS for relief of pain consists of the placement of an electrical conductor on the skin overlaying the nerves of the pain area, then applying electrical impulses through the conductor, similar in intensity to the body's own natural bio-electric currents.
NIKKEN is proud to introduce a highly sophisticated TENS unit called SOLITENS. Designed and structured like a flattened pen, this TENS unit comes equipped with individual set controls. The frequency of the beeper increases to confirm that proper contact has been made with the patient's skin in the affected pain area and that a return path is complete. Electrical impulses are then delivered to the nerve site to achieve pain relief.
SOLITENS is a portable, lightweight, compact, hand-held, long-term pulse duration TENS unit that requires no gels or pads. Although SOLITENS is easy to use, proper instructions from a physician or qualified health care professional should always be obtained prior to use. SOLITENS is a classified by the FDA as a class two medical device for pain control and requires a prescription in the United States.


The use of electricity for the treatment of ailments is not new. In 46 A.D.. Scribonius Largus reported the application of an electric fish in treating chronic headaches. As methods of artificially produced electrical currents were developed, various electrical devices became accepted in medicine. Their use became common in the 19th and early 20th centuries.
With the work of Melzack and Wall* and the publication of their gate theory of pain in 1965, a new era of research was begun into the application of electrical stimulus for relief.  TENS gained widespread use after the invention of the first wearable device. It was developed  in 1971 by Dr. Norman Shealy, a neurosurgeon, and David Maurer, a biomedical engineer.
Although the device was designed as a screening tool for selected patients as candidates for the implementation of dorsal cord stimulators, the use of TENS proved to be successful in  its effect on chronic pain to warrant its use as a primary treatment modality.

Principles of Operation
The ability of a TENS unit to relieve pain has been explained in many different ways. Two of the most cited mechanisms involve nerve transmission. One holds that TENS may block the transmission of impulses of the afferent nerves. The other focuses on the possible stimulation of endorphin (an endogenous opiate) production, which is a substance that is naturally produced in the human body whose function is to dull and de-sensitize nerves.
Solitens Function
A SOLITENS unit will accurately locate all trigger points throughout the body by an  audible tone indicator. Then SOLITENS will deliver an electric stimulus conducted by direct point contact to the pain site. The electric shock lasts 0.066 seconds with an alternation of 15 hz at 75 volts maximum, and contains both positive and negative pulses. The SOLITENS stim- ulator is a bi-polar device in which the first major pulse of energy is positive and bi-polar and 175 microseconds long, followed by a second major negative pulse of the same length,  followed by a delay.
Directions for Usage
Each SOLITENS device is equipped with a wrist band grounder (current connection) which must be worn at all times during treatment. Adjust the intensity and timing controls as pre- scribed to the required level and time length. Turn the unit on by pushing the switch to the ON mode; a light pitch should sound. While holding the device in a pen-like manner, and main- taining an even pressure on the electrode (tip of SOLITENS), pass it around the pain area; a higher pitch sound will begin and end as you pass the pain area, then return to the original  sound. The audible tone indicator notifies you when you are above the trigger point. Press the treatment button with your index finger for at least 15 seconds, then move to the next pain area. 

1. TENS units are designed to provide sensory and not motor stimulation. Motor  stimulation will cause muscle contractions that may aggravate pains.
2. TENS units are intended for the symptomatic relief of a large number of painful  syndromes until a cause can be found, the relief of chronic intractable pain syndromes, or cases where analgesic drugs would be contraindicated.
3. Results should not be expected within one or two applications. Your body will respond  at its own rate and results cannot be rushed.
