Laser Therapy Science and Clinical Studies

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 individuals have purchased a cold laser for private use. With the growing awareness of prescription drugs many people are turning to high quality therapeutic cold laser devices for effective for pain relief, inflammation reduction, microcirculation increase, and overall healing acceleration.

*While many of the following clinical studies have shown positive results, no medical claims are being made other than for those issued for pain and inflammation on a specific lasers that have been cleared for such by the FDA. 

Controlled Double Blind Studies with Photobiomodulation Therapy (PBMT) / Cold Laser Therapy (CLT) / Low Level Laser Therapy (LLLT)

Following is a list of cold laser controlled, randomized, double-blind studies,* which have shown that Cold Laser Therapy is an effective treatment modality for a wide range of treatment indications such as:

• Achilles tendonitis
• Ankle sprains
• Arthritis
• Carpal tunnel syndrome
• Chronic back pain
• Chronic neck pain
• Epicondylitis
• Herpes simplex
• Lymphedema
• Myofascial pain syndrome
• Oral mucositis
• Shoulder pain
• Sports injuries
• Stroke
• Temporomandibular dysfunction
• Tinnitus
