The effective management of pain is possible in many cases with the use of electrotherapy. In most instances, chronic pain is the result of an injury or accident. It may have also been caused by a chronic illness. It can occur in essentially any part of one's body, but some common areas in which pain is experienced are the knees, shoulders, and back. A TENS 7000 unit can be very advantageous to individuals faced with chronic pain.

A TENS unit is a device that makes use of tiny amounts of electric current. The acronym TENS stands for transcutaneous electrical nerve stimulator. The unit delivers the mild currents through electrodes that are attached to the person's skin. This kind of electrotherapy specifically targets only the region in which the patient's worst pain is felt.

Such machines are usually recommended by those employed at pain clinics. Healthcare practitioners such as physical therapists, as well as sports coaches, may also recommend their use. The person's level of pain is usually relieved immediately when the device is attached, and it can be used continuously or intermittently. Most people report substantial relief from their symptoms when such a device is used.

TENS devices send electrical impulses to the nerves beneath one's skin. Wherever the electrodes are placed are where the nerves will be stimulated the most. In most cases, the sensation of pain is abruptly decreased or stopped altogether during use.

The amount of pain relief experienced will vary substantially from one person to another, and it will depend on why the person is experiencing pain, how long he or she uses the machine, and therapy mode select. For many individuals, relief is experienced for a long time after the device is turned off, which many people find very advantageous. In rare cases, pain relief is only the experienced when the device is running.

Transcutaneous electric nerve stimulators can offer the benefits outlined above when used in a medical facility or in the user's own home. The patient can adjust the frequency to a level that suits him or her. High-frequency or low-frequency stimulation can be selected, depending on what one's doctor recommends, and his or her individual preferences. It is often necessary to try different settings prior to finding the most effective one.

High intensity stimulation is known as conventional. A person can usually tolerate it for lengthy amounts of time, but the relief from his or her pain will only last for a short time after the device is shut off. Low intensity stimulation is typically tolerable for only thirty minutes at a time, as it can be somewhat uncomfortable. However, it offers pain relief for lengthier periods of time.

The most common treatments for chronic pain are over-the-counter medications or prescription drugs. As well as being costly, however, such drugs are associated with negative side effects, such as tolerance, sleepiness, and dizziness. A TENS 7000 device by contrast, provides relief for back pain, osteoarthritis, joint inflammation, tendinitis, sciatica, and other kinds of chronic pain without the need for medication. Such therapy is also very affordable, making it an excellent choice for virtually anyone suffering from painful conditions.
