It is a form of treatment, which makes use of electrical impulses for treating damaged tissues, repairing muscles, and strengthening muscles by sensitizing them. There is historic evidence of the use of electrical stimulation for pain relief. The last two centuries have seen many electrostatic devices being used for pain control.
The therapy uses electrical signals to intervene the pain transmission signals into the brain. This in effect, creates disturbances in the message send from the nerve to the brain. The therapy is very useful when traditional medicines aren’t effective.
It can also involve the use of this electric current to hasten the healing of tissues where the damage has occurred and is taking too much time to heal.
Forms of Electrotherapy
Ultrasound, TENS, Laser Therapy and stimulation, and Inferential Therapy are its few forms. While sound waves are used for healing in ultrasound, TENS use electric signals to relieve you from pain. Laser therapy, as the name suggests, makes use of laser light to repair the damaged tissues. It ensures that therapy is accurate and precise.
TENS (Transcutaneous Electrical Nerve Stimulation)
It is commonly used as a non-invasive way of relieving the painful conditions such as:
- Lower Abdomen Pain
- Labor Pain
- Phantom Pain etc.
Working of TENS (TENS Electrotherapy)
Simply put, it is a small device which is capable of delivering electrical signals across the skin and into the affected area. Wires connect this device to sticky pad electrodes, which are placed on the skin in the affected area of pain. When the low-intensity electric signals pass through the affected area, they give relief from pain.
It is an enhanced form of TENS and makes use of two high-frequency currents which are usually out of phase. Their flow interferes and generates a beat frequency which stimulates the affected region.
Therapy is usually executed by physiotherapists, the various clinical applications where it has been found to be effective are:
- Pain Relief
- Stimulation of Muscles
- Local Blood Flow Increase etc.
Shorter treatment time, not exceeding 10 minutes, is usually sufficient to achieve the effect in acute conditions. The therapy is used as a complement to other physiotherapy techniques. These days you can find wired and wireless TENS unit supplies. Besides, the accessories are available as well to get the desired treatment for the affected location. You can find electrodes in various shapes and different clothing material meant for various pain areas.
