Package Includes:

Note: With proper care, electrodes can be reused for multiple applications. We recommend purchasing Pre-TENS electrode spray, additional electrodes and rechargeable batteries with your tens unit.

  • stimulator
  • lead wires (new FDA compliant)
  • 4 self-stick reusable electrodes
  • 9-volt battery
  • soft carrying case
  • instruction booklet


  • Cardiac Pacemakers - Do not use the TENS unit with demand type Cardiac Pacemakers.
  • Throat (Carltid Sinus) - Do not use over the nerves, muscles or arteries of the throat or the larynx (voice box) - strong muscle contractions could close the airway.
  • Eyes - Do not use on the eyelids.
  • Head - Do not place electrodes so electrical flow is from one side of the head to the other.
  • EKG Monitors & Alarms - Monitors and alarms for EKG units may not operate properly when the unit is in use.
  • Myocardial Disease or Arrythmias - The TENS unit should be used by patients with these conditions only under the direction and supervision of the prescribing physician.
  • Pregnancy - The safety of the TENS unit during pregnancy or delivery has not been established.
  • Undiagnosed Pain - Do not use the unit to treat undiagnosed pain syndromes.
  • Machinery Operation - Do not adjust the control setting of the unit while operating vehicles, heavy equipment, machinery or tools.
  • Children - Keep out of reach of children.

Product Reviews


For use with the ProMed 660 Portable Ultrasound Unit.

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.
