"TENS" is the acronym for Transcutaneous Electrical Nerve Stimulation. A "TENS unit" is a small, portable, battery-operated unit that sends electrical impulses to certain parts of the body to block the pain signals.
The electrical currents produced are small, but prevents pain messages from being sent to the brain and may raise the level of endorphins (pain killers produced by the brain).
TENS units should only be used under supervision of a doctor or physical therapist. Electrodes are attached to the skin over or near the area where you are experiencing pain.
It is important that you know how to:
correctly place the electrodes (proper placement is important)
operate the tens unit
replace the batteries
vary the controls and settings (both the frequency and voltage)
set the proper duration and intensity of the stimulation (which depends on the location and type of pain)
TENS units are prescribed for both acute pain and chronic pain conditions such as:
- arthritis
- joint pain
- fibromyalgia
For some chronic pain patients, a TENS unit provides pain relief that can last several hours.
For others, a TENS unit may reduce the amount of pain meds needed. Some patients hook the unit onto a belt turning it on and off as needed.
The cost of a TENS unit can range from about $100 to several hundred dollars. TENS units can be purchased right here on AllTimeMedical.com. A prescription usually is necessary for insurance reimbursement of a TENS unit.
