What is Electrotherapy?

Electrotherapy is a drug-free, non-invasive treatment method that uses electrical energy to treat different medical conditions and heal wounds. This alternative medicinal practice has been in use since the 1800s; initially, it was limited to certain diseases, but now many illnesses are being treated using electrotherapy. Electrotherapy involves a range of treatments using electricity to decrease pain, improve blood flow, strengthen muscles, repair tissues, and promote bone growth, leading to overall improvements in physical functioning.

We carry electrodes, ultrasound therapy devices, TENS and EMS units, combination units, conductive garments, electrotherapy skincare items, and other accessories. Recognized brands are featured here, including Unipatch, Kendall, BioKnit, BioStim, etc., and get amazing deals on all these products.

How does Electrotherapy work?

  • Electrotherapy has proven to be a safe, effective, non-operative treatment method without any side effects.
  • An electrical signal is sent to the brain from the damaged nerve whenever you feel pain.
  • In the electrotherapy treatment method, electrical impulses are sent to interrupt or block the transmission of neural pain signals into the brain.
  • It effectively distracts the message from the nerve to the brain, thereby reducing the pain you feel.
  • Small electrical devices are used to send electrical signals across the skin.
  • Electrodes are placed on the skin in the area of the pain.
  • It allows a low-intensity electric charge to be transmitted across the area that stimulates the body to produce natural pain relievers that help block the pain signals.
  • Electrotherapy also uses electric current to speed up tissue healing where tissue damage has occurred.

Benefits of Electrotherapy in Physical Therapy

Physical therapists use various tools to restore range of motion, manage pain and treat musculoskeletal conditions. They may use electrotherapy to treat various musculoskeletal illnesses by using controlled and targeted electrical stimulation. Electrotherapy may offer the following benefits:

  • Relaxation of muscle spasms
  • Prevents muscle atrophy
  • Facilitates wound healing
  • Improves local blood circulation and flow
  • Re-education of muscles using targeted stimulation
  • Preserve and improve range of motion
  • Management and reduction of pain
  • Prevention of deep vein thrombosis post-surgery

Types of Electrotherapy Devices

Electrotherapy uses a variety of devices that transmit electrical impulses across the body via electrodes placed over the patient’s skin for purposes related to injury treatment and rehabilitation. All the electrotherapy devices are more or less similar; however, they vary in frequencies, waveforms, and effects. Popular electrical stimulation modalities include ultrasound therapy, TENS (Transcutaneous electrical nerve stimulation), NMES (Neuromuscular electrical stimulation), interferential therapy, and microcurrent therapy.

Transcutaneous Electrical Nerve Stimulation (TENS)

TENS therapies are the most widely used electrotherapy modality, as patients can use the small TENS units at home and wherever else they may go. TENS therapy effectively treats pain from injuries, surgeries, and disease conditions such as arthritis. It is a small, battery-operated device that delivers a low-voltage electrical current through the skin via electrodes attached to the skin. The electrical current helps stimulate the nerves in the affected area and transmits signals to the brain that distort the pain signals.

Neuromuscular electrical stimulation (NMES)

Neuromuscular electrical stimulation (NMES) involves using a device that sends low-frequency electrical impulses via electrodes. The electrical impulses stimulate the nerves in desired muscles, causing them to contract, enhancing muscle strength and endurance, motor learning, and muscle re-education. This treatment also helps reduce pain and swelling in the muscles. Athletes and people who suffered an injury or had to stay inactive for a prolonged period can benefit from NMES therapy. The therapy helps bring back mobility and promotes healthy blood flow.

Ultrasound Therapy

Ultrasound devices use high-frequency sound waves to promote circulation to the affected area. Many ultrasound devices combine ultrasound therapy with electrical stimulation to achieve more efficient and maximized healing benefits.

Contraindications for Electrotherapy

Electrotherapy should not be used for people with following conditions, including

  • Pregnancy
  • Cognitive impairment
  • Patients with medical implants or stimulators like cardiac pacemaker
  • Deep vein thrombosis
  • Certain cardiovascular diseases
