      Transcutaneous Electrical Nerve Stimulation (TENS)

      TENS is a non-invasive, drug free method of controlling pain, which uses tiny electrical impulses sent through the skin to nerves in order to modify your pain perception. In most people it is effective in reducing or eliminating the pain.

      Electronic Muscle Stimulation (EMS)

      EMS works by sending electronic pulses to the muscle(s). This is achieved by sending low frequency electric pulses through muscle tissue causing them to gently contract. In this way the muscles are passively exercised and blood flow is increased

      Galvanic Stimulators

      Galvanic Stimulators use direct current, which creates an electrical field over the treated area. The positive pad works like ice, causing reduced circulation to the area under the pad. The negative pad works like heat, causing increased circulation.


      IF sends small comfortable electrical impulses through your skin to work on deeper tissue stimulation. The sensation works to prevent pain signals from reaching the brain.


      Infrared Light Therapy help the body by delivering specific light waveforms that increase circulation. Increasing circulation helps promote healing, lessen swelling, and helps in reducing pain.


      Portable Ultrasounds give advanced pain relief using sonic stimulation of soft tissue cells. They generate pulsed, high frequency sound waves, which travel deep into the tissue, generating vasodilation. This helps increase blood flow to the treated area.


      Russian stimulation uses medium frequencies to provide stimulation to muscle groups. This is used to reduce muscle spasms as well as for muscle strengthening. This method was created to produce maximal muscle strengthening effects.

      Micro Current

      Microcurrent Therapy uses extremely small amounts of electrical current (millionths of an amp) to help relieve pain and heal soft tissues of the body. The electrical current used in Microcurrent Therapy is so small that it is rarely felt.
