Electric current is applied to the body via electrodes placed over the skin for therapeutic benefits. There is a wide range of different frequencies that can be used to provide a variety of different effects. Electrical current can be used to stimulate sensory nerves and block the pain sensation, stimulate motor nerves to generate muscle contractions, or to create a “pumping’ effect to reduce swelling and inflammation.
Some of the types of currents commonly used are TENS, IFT, Russian currents, Faradic and Galvanic currents and so on. Choosing the appropriate current type and frequency is an important factor in achieving the desired therapeutic effect based on the specific needs of the patient.
The following are the benefits of using electrical stimulation:
- Decrease pain, swelling and inflammation
- Decrease radiating pain caused due to impinged nerve or prolapsed intervertebral disc.
- Strengthen weak muscles.
- Stimulate muscle contractions after nerve injury.
