What its use in physiotherapy and how?

Transcutaneous electrical nerve stimulation (TENS) is a physiotherapy technique that uses low-voltage electrical currents to provide relief from pain and muscle spasms. It is effective for acute, subacute, and chronic pain conditions. TENS works by stimulating the release of endorphins, the body's natural pain relievers. It also blocks pain signals from being sent to the brain. TENS units can be used for both professional and home use. There are many different types and brands of TENS units available. Some common TENS uses in physiotherapy include:

- Musculoskeletal pain, such as lower back pain, neck pain, shoulder pain, and knee pain

- Nerve pain, such as sciatica, carpal tunnel syndrome, and diabetic neuropathy

- Headache pain

- Postoperative pain

- Chronic pain conditions, such as arthritis and fibromyalgia

TENS is typically used in combination with other physiotherapy techniques, such as massage, exercise, and electrical stimulation. It is a safe and effective way to relieve pain and improve function.

Here are some specific examples of how TENS is used in physiotherapy:

- Back pain: TENS units can be used to relieve lower back pain and neck pain. The electrodes are placed over the painful area, and the unit is turned on. The current will help to relieve pain and muscle spasms.

- Shoulder pain: TENS units can also be used to relieve shoulder pain. The electrodes are placed on the shoulder, and the unit is turned on. The current will help to reduce pain and inflammation.

- Knee pain: TENS units can be used to relieve knee pain. The electrodes are placed on the knee, and the unit is turned on. The current will help to reduce pain and swelling.

- Nerve pain: TENS units can be used to relieve nerve pain. The electrodes are placed over the affected nerve, and the unit is turned on. The current will help to block pain signals from being sent to the brain.

- Headache pain: TENS units can be used to relieve tension headaches and migraines. The electrodes are placed on the temples, forehead, or back of the neck. The unit is turned on, and the current will help to relax the muscles and reduce pain.
