1. TENS (Transcutaneous Electrical Nerve Stimulation):

   • Used for pain relief.
   • Delivers low-voltage electrical current to nerve endings via surface electrodes.

2. EMS (Electrical Muscle Stimulation):

   • Stimulates muscle contractions to improve strength and prevent atrophy.
   • Commonly used after injuries or surgeries.

3. IFC (Interferential Current Therapy):

   • Uses two high-frequency currents to target deeper tissues.
   • Effective for pain relief and reducing inflammation.

4. Ultrasound Therapy:

   • Uses high-frequency sound waves to promote tissue healing and improve blood circulation.

5. Laser and Light Therapy:

   • Employs low-level laser or light to accelerate tissue repair and reduce inflammation.

6. Iontophoresis:

   • Delivers medication through the skin using electrical currents.
   • Often used for localized pain or inflammation.

7. Microcurrent Therapy:

   • Uses very low-intensity currents to stimulate cell repair and reduce pain.

Benefits of Electrotherapy

• Pain Management: Reduces acute and chronic pain without medication.
• Muscle Strengthening: Helps restore muscle function post-injury or surgery.
• Enhanced Healing: Promotes tissue repair and reduces swelling.
• Improved Circulation: Encourages blood flow to the affected area.
• Relaxation: Relieves muscle spasms and tension.

Common Uses in Physiotherapy

• Back and neck pain.
• Sports injuries.
• Post-surgical recovery.
• Neurological conditions (e.g., stroke, Bell’s palsy).
• Arthritis.
• Tendinitis and bursitis.

Precautions

• Not suitable for individuals with pacemakers, pregnancy (in certain areas), or open wounds.
• Should be administered by trained professionals to avoid adverse effects.
