Electrotherapy

Modulation of the Somatosensory System for Pain Relief and Rehabilitation Therapy

Electrotherapy involves the application of specific frequencies and intensities of electric current to treat diseases or injuries. Common electrotherapeutic modalities used in physiotherapy include: Transcutaneous Electrical Nerve Stimulation (TENS), Neuromuscular Electrical Stimulation (NMES) and Interferential Therapy.

TENS

TENS applies electric current through electrodes to specific body areas, stimulating nerves and muscles. This can help relieve pain, reduce muscle spasms, enhance muscle contraction, and promote blood circulation.

The effects of TENS are generally immediate, like taking pain medication prescribed by a doctor. The pain relief wears off, so TENS should be used in conjunction with other treatments.

TENS is suitable for:

  • Simple joint pain
  • Muscle soreness and tension
  • Acute and chronic pain relief
  • Home use for pain management

NMES

NMES combines electrotherapy and exercise therapy, using electrical currents to stimulate muscle contractions and improve muscle strength and function.

NMES is suitable for:

  • Neuromuscular injury
  • Stroke
  • Muscle atrophy
  • Supplementary muscle strengthening
  • Post-operative rehabilitation

Interferential Therapy

Interferential therapy is a specialized electrotherapy technique that uses specific frequencies and intensities of interferential currents to treat pain and relax muscles. The intersecting effects of the currents produce a stimulatory effect on nerves and muscles.

Interferential therapy can be used to relieve pain, reduce inflammation, improve blood circulation, and increase tissue metabolism.

Interferential therapy is suitable for:

  • Chronic deep-seated pain
  • Muscle soreness and tension
  • Poor blood circulation in joints and muscles

Precautions for Electrotherapy and Interferential Therapy

Electrotherapy is generally not recommended or requires special attention in the following cases:

  • History of epilepsy
  • Patients with metal implants, like pacemakers or prosthetic devices
  • Pregnancy
  • Coagulation disorders or vascular occlusion
  • Tumors near the treatment site
  • Skin allergies or infections at the treatment site

 

Electrotherapy and interferential therapy are typically part of a comprehensive physical therapy plan and should be used in combination with other treatment modalities to achieve optimal rehabilitation outcomes.
