Electro-Therapy Overview

There are several electro-therapy modalities available to meet the various needs of your patients. Not all devices produce the same results, nor do all individuals respond the same way to all electro-therapies. Below you can find descriptions of the various devices and modalities in laymen's terms. Understanding the differences and what each can accomplish will help you best counsel your clients to help them navigate their way to the best possible solution for them.

TENS Therapy


T.E.N.S. (Transcutaneous Electrical Nerve Stimulation) is a non-invasive, drug-free method of controlling pain. The T.E.N.S. frequency sends comfortable electrical impulses through the skin to divert the attention of the nerves away from pain and occupy the nerve pathways with a more comfortable sensation, which decreases your perception of pain.


  • Symptomatic relief and management of chronic (long-term) intractable pain
  • Adjunctive treatment for post-surgical and post-traumatic acute pain
  • Chronic & acute pains
  • Back & cervical muscular and disc syndromes
  • RSD
  • Arthritis
  • Shoulder syndromes
  • Neuropathies

EMS/NMES Therapy


EMS (Electrical Muscle Stimulation) uses electric impulses to elicit muscle contraction. The electrical impulses omitted from an EMS device mimic signals normally coming from the central nervous system. They cause the repetitive contraction and relaxation of the muscle. Studies have shown EMS to be beneficial for the prevention of muscle edema and atrophy by increasing blood circulation. Positive results have also been shown for the adaptation (training) of skeletal muscle fibers.


  • Relaxation of muscle spasms
  • Prevention or retardation of disuse atrophy (wasting of muscle due to lack of use)
  • Increasing local blood circulation
  • Muscle re-education, such as after surgery or trauma
  • Maintaining or increasing range of motion or joint mobility
  • Preventing venous thrombosis (blood clots due to inactivity) post-surgically
  • Post-orthopedic surgery
  • Joint replacement (i.e. hip, knee, shoulder)
  • Muscle strengthening programs
  • Shoulder subluxation
  • Reduction of muscle spasms

 

Interferential Therapy


The original concept of interferential therapy was developed over 57 years ago by Austrian physician, Dr. Hans Nemec. He found that by crossing two slightly different medium frequency alternating currents within the tissue; a third frequency current of greater intensity is created in the deeper tissue, effectively delivering deep therapeutic benefits for pain control and speeding up the healing process while maximizing patient comfort. Electrode placement should be in an "X" pattern, as the point of intersection provides the third stronger frequency.

  • Symptomatic relief and management of chronic and post-traumatic acute pain
  • Management of post-surgical pain
  • Pre- and post-orthopedic surgery
  • Joint injury syndrome
  • Cumulative trauma disorders
  • Inflammatory conditions
  • Pain control of various origins

 

Galvanic Therapy


Named after Italian physiologist Luigi Galvani (1737 - 1798), Bell Telephone Laboratories developed the first high voltage Galvanic Stimulator in 1945. Unlike low voltage alternating current (AC) that is found in TENS, EMS/NMES and IF, Galvanic Stimulation is a source of high voltage direct current (DC). Unique in its application, a large dispersive pad is placed in a neutral area on the body to ground the current while the smaller "active" pads are placed over treatment area.

  • Treating acute injuries associated with major tissue trauma with bleeding or swelling.
  • Quickly increasing blood circulation and reducing edema.
  • Accelerating wound healing time.
  • Effective pain relief by overriding the pain signals sent by the body
  • Stimulating muscles and nerves
  • Altering or changing blood flow direction
  • To address soft-tissue inflammation.
  • Relaxation of muscle spasms
  • Prevention of atrophy
  • Muscle re-education
  • Maintaining or increasing range of motion or joint mobility
  • Diabetic neuropathy
  • Preventing of blood clots
  • Sprains and strains
  • Degenerative point disease
