Electrotherapy

Electrotherapy is used to help manage pain, increase the rate of healing and improve the quality of the tissue repair. Electrotherapy uses an energy source to stimulate changes in the tissue. Here at advance Physiotherapy & sports injury clinic we use electrotherapy modalities such as therapeutic ultrasound. With certain conditions we may advise the use of a transcutaneous electrical nerve stimulation (TENS) unit whilst at home as this can reduce pain levels (TENS machines can be bought from local pharmacies).

Electrotherapy works best when accompanied by a rehabilitation programme working on gradually loading the tendons and joints. Rehabilitation must accompany any tendon or meniscus issues for treatment to be effective.

Tendons need to be stimulated through loading for their tensile strength to increase, which forms an essential part of the recovery process.

Joints need to be loaded and moved in order for the body to provide important nutrients to the area to enable normal healing.

Ultrasound and other electrotherapies are most commonly used in the recovery of an acute injury sustained to the muscles and tendons. Therapeutic ultrasound works through an ultrasound probe that makes contact with the skin through a coupling gel. Different frequencies and time lengths are chosen depending on the depth and size of the injured area.

TENS machines use a mild electrical impulse to provide pain relief to a sore area. The continued stimulation of the area helps to block pain signals through a mechanism called the pain gate. When the gate is open messages can reach the brain but when the gate is closed the signals do not reach the brain. TENS machines close the pain gate and help provide pain relief. TENS machines are most commonly used for people with musculoskeletal pain such as chronic low back pain,osteoporosis and arthritis.

Without movement, strengthening and rehabilitation of the injured area, electrotherapy is unlikely to have any benefit.
