Low Level Laser
Low Level Laser or Cold Laser is a new modality in the United States. Approved by the FDA in 2002, it has been in use in Europe and Canada since the 1960's. Lasers are used for pain management, edema and wound healing. Lasers cause no pain or muscle contraction to the patient. THere is no heating effect due to the introduction of light. It does no damage to tissue and is safe in most applications, therefore ensuring good patient compliance.
Laser is an acronym for Light Amplification by Stimulated Emission of Radiation. The Laser instrument produces a very thin beam of light in which energy is concentrated. Therapeutic lasers include both visible and invisible light. The radiant power output can extend from 1 mWatt to 500 mWatts. This is quite low compared to surgical lasers, which range between 3,000 and 10,000 mWatts.
Low Level Lasers promote healing by increasing ATP levels(the energy source needed for cell function) and activating enzymatic pathways, the growth factor response, protein synthesis and improving cell proliferation. This modality also causes endorphin release, therefore decreasing pain. It also strengthens the immune system by increasing levels of white blood cell activity. Low Level Lasers also decrease inflammation.
Low Level Laser can penetrate up to 25cm which is greater than most modalities currently in use. Depth of penetration is affected by tissue hydration, skin complexion and other properties of the tissue. This modality should not be used over a site that is cancerous, infected, or that has a tattoo on it. Contraindications also include it's use over a pregnant womb.
Eberle's Physical Therapy, Inc. was the first practice in Northwestern Pennsylvania to obtain and use a Low Level Laser to treat patients. We have had remarkable success in treating low back pain, tendonitis, contusions, sprains, carpal tunnel syndrome, nerve injuries, edema and chronic wounds.
