To date, there are now over 6000 Positive Clinical Studies and Research Papers that support Photobiomodulation Therapy (PBMT) / Cold Laser Therapy (CLT) / Low-Level Laser Therapy (LLLT) as an effective modality for a wide range of conditions. Over 200,000 health care providers are using cold lasers devices in their practice and over 800,000 have purchased a laser for private use. High quality therapeutic cold laser devices are effective for pain relief, the reduction of inflammation, increasing microcirculation, and promoting the body's natural healing process.
*While many of the following clinical studies have shown positive results, no medical claims are being made other than for those issues such as pain and inflammation, for a specific lasers that have been cleared for such by the FDA.
