Electrotherapy uses small, controlled electrical currents to relieve pain, stimulate weak muscles or reduce swelling. Common forms include TENS, which is used for pain relief, and electrical muscle stimulation, which helps activate muscles weakened by injury, surgery or nerve problems. It is generally used as part of a programme that includes exercise and hands-on treatment.

Patients seeking a physiotherapy hospital in Mumbai with electrotherapy are checked for safety first. The therapist asks about pacemakers, pregnancy, skin conditions, numbness, epilepsy and implants. Pads are placed on clean, healthy skin, and the current is increased slowly until the patient feels a comfortable tingling or buzzing. Patients must not feel pain or burning. A session often lasts fifteen to twenty minutes, and the therapist stays close and checks the skin.

Electrotherapy is most useful when it helps a person do something they could not do before. For example, easing pain enough to begin exercise, waking up a weak muscle so that it can work with other muscles, or reducing swelling in the first days after an injury. It is rarely a stand-alone treatment, and the plan is reviewed regularly. If there is no benefit after a few sessions, the therapist changes the approach.

How the Procedure Can Help

It can ease pain for a time, help activate weak muscles, support early movement and make exercise easier to start. Many patients find that it helps them sleep or move more comfortably, although the relief may be short-lived without exercise.

Risks and Considerations

Skin irritation or, rarely, burns can occur. Electrotherapy is avoided in people with pacemakers or other implanted electrical devices, over broken or infected skin, over the front of the neck, near the eyes and over the abdomen or lower back in pregnancy. It is also avoided in areas where sensation is reduced, as the patient may not feel the current. Patients should tell the therapist about any unusual sensation, heat or discomfort during treatment.
