I’ve been a chronic pain patient since 1995 and became permanently disabled due to further chronic pain caused by cervical and thoracic laminectomies in 1999. The chronic pain, with accompanying migraines, was 24/7 and muscular-skeletal. Synthetic opiates and chiropractic care… [Read More]
Cold laser therapy, so called because it is unlike older types of lasers that use very hot, high-energy beams of light, also is known as low-level laser treatment (LLLT). Dr. Stengler uses LLLT in his clinic to relieve many types of musculoskeletal pain, including arthritis and strained or inflamed muscles, joints, tendons and ligaments. Because LLLT reduces inflammation naturally it helps patients achieve pain relief more rapidly and without the risk of conventional therapies such as steroid injections or prescription painkillers. I also use it to treat conditions such as sinusitis…lymphedema (swelling due to a buildup of lymph fluid in an arm or a leg, which is particularly common after a mastectomy)… and tinnitus (a condition characterized by ringing in the ears). LLLT also has been shown to speed up wound healing and improve the symptoms of carpal tunnel syndrome.
One of the things that I really like about LLLT is that it is a nontoxic treatment with virtually no side effects. LLLT of one type or another has been in use for about 30 years, but the technology has become more effective and has increased in popularity in recent years. In LLLT, laser light passes harmlessly into the body’s tissues without heating them. LLLT devices deliver energy units called photons to damaged cells. This stimulates and increases the cells’ metabolic activity and, in essence, brings them back to health. LLLT uses different wavelengths to penetrate to varying depths—from just below the skin’s surface to four to five inches deep. Depending on the area being treated, the therapy may employ one or more wavelengths during a treatment session. The laser in my clinic, like many others now in use, enables me to vary the frequency of wavelengths.Once these photons reach their target depth, they produce a variety of effects that help reduce pain and accelerate healing by…
Numerous studies have demonstrated LLLT’s effectiveness. One 2009 study published in The Lancet was an analysis of 16 randomized controlled studies of LLLT for neck pain. The researchers concluded that patients were about 70% more likely to experience reduced pain following LLLT, compared with those given a placebo treatment. Similarly, a 2008 study published in American Journal of Sports Medicine found that recreational athletes with chronic Achilles tendinopathy who received LLLT combined with therapeutic exercises had faster recovery times. The laser group recovered after four weeks of treatment, compared with 12 weeks for the control group, which received no laser therapy.
When I use LLLT, I usually pass the laser over the affected area for five to 10 minutes per treatment. I often administer one to two treatments per week until symptoms resolve. Many people notice at least some improvement in pain, soreness and stiffness after just one treatment, and 90% of my patients notice a significant reduction in pain within two to three treatments. Benefits can last from weeks to months depending on the individual and the problem being treated. If desired, LLLT also can be used in conjunction with other therapies, such as physical therapy, anti-inflammatory medications and acupuncture. Laser treatments for conditions such as sinusitis and tinnitus work similarly.
For patients with acute or chronic pain, LLLT is a great choice. Take Susan, for example. This 65-year-old patient had severe bursitis in her hip. She was in so much pain that she had to walk with a cane. Another doctor had recommended a cortisone injection to relieve the pain, but she wanted to see what other treatments were available. There was no question in my mind that LLLT would help her. After just one treatment, her symptoms improved dramatically. After three treatments, she felt so much better and had such increased mobility that she no longer needed the cane. People with cancerous tumors should not have this treatment because it may aggravate their condition. Lasers have not been tested on pregnant women.
