A transcutaneous electrical nerve stimulation unit (TENS) is a battery-operated device used by some to relieve pain.
TENS units operate by supplying tiny electrical impulses to a person's skin through electrodes that have adhesive pads.
TENS units may help treat the following symptoms:
- period pain
- labor pain
- postoperative pain
- joint pain
- neck and back pain
They may also alleviate the pain that results from the following conditions:
- sports injuries
- multiple sclerosis
- painful diabetic neuropathy
- spinal cord injury
This has controls that allow people to take adequate pain relief. Through manipulating the following elements of electrical current, people will do this:
1.Level: A dial lets the user set the electrical stimulus intensity.
2.Frequency: The frequency corresponds to the number of pulses in electricity per second.
- High-frequency (HF) pulses range from 80 to 120 cycles per second, which can aid with acute pain relief.
- Low-frequency pulses (LF) range from 1 to 20 cycles per second and are ideal for chronic pain management.
3. Duration: The length is the number of microseconds for each pulse that the current reaches the skin for.
