INTRODUCTION TO TENS What is Pain? Pain is the body’s warning system. Pain is important because it signals an unusual condition in the body and alerts us before additional damage or injury can occur. TENS was developed to help relieve some types of chronic and acute pain. How does TENS work? TENS is a method of treating pain that is non-invasive and does not use pharmaceuticals. The TENS device sends impulses through the skin that stimulate the nerve (or nerves) in the treatment area.
Contraindications - Patients with implanted electronic devices ( for example, a pacemaker ) or metallic implants should not undergo TENS treatment without first consulting a physician. - Any electrode placement that applies current to the carotid (neck) region. - Any electrode placement that causes current to flow transcerebrally (through the head). - The use of TENS whenever pain symptoms are undiagnosed, and the etiology is unknown.
PRECAUTIONS/ADVERSE REACTIONS Caution: Isolated cases of skin irritation may occur at the site of electrode placement during long term application. Caution: Effectiveness is highly dependent upon patient selection by a person qualified in the management of pain patients. Caution: Skin irritation and electrode burns are potential adverse reactions.
ABOUT THIS DEVICE Your TENS device is a battery operated device that includes two controllable output channels. This TENS device creates electrical impulses whose amplitude, duration, and modulation can be altered with the controls or switches. The TENS intensity controls are very easy to use, and the slide cover protects accidental changes in settings. UNIT CONTROLS Panel Cover A cover which conceals the controls for the Pulse Width, Pulse Rate, and Mode Selector.
Mode Functions Burst (B) releases individual bursts twice per second, pulse width is adjustable and the pulse rate is set at 100Hz per second. Continuous (C) stimulation is delivered continuously at the settings determined by intensity, rate, and width knobs. Modulation (M) pulse width decreases the pulse width down to 60% of the original width setting. This decreased pulse width is maintained for 1.5 seconds before returning to the original width setting, which is maintained for 3.5 seconds.
TIPS FOR SKIN CARE Good skin care is important for effective and comfortable use of your TENS device. - Always clean the electrode site with mild soap and water solution, rinse well and dry thoroughly prior to any electrode application. - Any excess hair should be clipped, not shaved, to ensure good electrode contact with the skin. - If a skin treatment is recommended by your physician, apply the skin treatment as recommended, let dry, and apply electrodes as directed.
3. Place electrodes on the skin Place the electrodes on the skin as recommended by your clinician. 4. Insert the Lead Wire Connector to the TENS device Plug the end of the lead wire into the lead connector port to be used, pushing plug in as far as it will go. 5. Select Treatment Settings Ensure the unit is set to the proper settings (Pulse Width, Pulse Rate, and Mode Selector), recommended by your physician. 6. Adjusting Channel Intensity Control Locate the intensity control knob at the top of the unit.
Changing the battery When the yellow indicator light on the front of the unit does not light up when the unit is turned on, the battery should be replaced. 1. Remove the panel cover by pressing on the top and sliding down until it is completely removed from the unit. This will reveal the battery compartment. 2. Remove the discharged battery from the device. 3. Place a new battery in the battery compartment. Note the proper polarity alignment indicated on the battery and the compartment.
TROUBLESHOOTING If the TENS device does not function properly: 1. Make sure the battery is properly installed or replace the battery. Be sure to observe proper polarity markings when replacing the battery. If the yellow light on the front of the unit does not stay lit when the unit is turned on, replace the battery and check again. 2. If the ON/OFF Indicator Light is flashing and no stimulation is felt, check to ensure lead wires are properly connected and the electrodes are in place.
