Clinical Applications

Written By Valerie Krossin

Class IV therapy laser is appropriate across a wide spectrum of conditions. The following are supported by published clinical evidence:

Musculoskeletal Pain

RCTs report 30–50% VAS pain reduction; improved disability scores .

  • Chronic and acute low back pain

  • Cervical pain / neck pain

  • Knee osteoarthritis and joint pain

  • Shoulder pain and rotator cuff injuries

  • Hip and sacroiliac pain

  • Plantar fasciitis

  • Tendinopathies (Achilles, patellar, lateral epicondyle)

  • Fibromyalgia

  • Rheumatoid arthritis and inflammatory arthritis

  • Post-surgical rehabilitation and recovery

  • Sports injuries (muscle strains, ligament sprains, contusions)

  • Temporomandibular joint (TMJ) disorders

Neuropathic Conditions

  • Peripheral neuropathy (including diabetic neuropathy)

  • Spinal cord injury support

  • Traumatic brain injury (adjunct)

  • Post-stroke rehabilitation support

  • Neurodegenerative conditions such as Parkinson’s, Alzheimers support

  • Depression, Anxiety, ADHD support

Wound and Post-Surgical Recovery

  • Accelerates wound closure and reduces infection risk in diabetic ulcers and post-surgical incisions.

  • A pilot study of 100 cardiac surgery patients found Class IV laser therapy (5–7 J/cm²) .significantly reduced postoperative pain scores compared to standard multimodal analgesia.

  • Post-surgical healing time reduced by up to 50% for incision sites in some clinical series.

Sports Medicine and Athletic Recovery

  • Pre-exercise application reduces muscle damage markers; post-exercise application accelerates recovery.

  • Appropriate for sprains, strains, contusions, bursitis, and overuse injuries.

Dermatologic and Other Applications

  • Shingles (herpes zoster) pain; eczema; psoriasis; acne.

  • Temporomandibular disorder (TMD): high-certainty evidence for pain reduction, improved function, and quality of life .

  • Chronic and diabetic wound ulcers

  • Decubitus (pressure) ulcers

  • Scar tissue remodeling

  • Burn wound healing

  • Acute radiation dermatitis

  • Lymphedema management

  • Post-chemotherapy recovery support

As a nurse and educator with over 16 years of experience in the field of photobiomodulation (PBM), I have witnessed firsthand the transformative impact of this innovative therapy on pain, healing and sports recovery and performance enhancement. As the Educational Director and Senior Account Manager for industry leaders ASPEN Laser and TheraLight, I have been instrumental in forming strategic alliances with health professionals, businesses, individuals and professional and collegiate teams.

PBM harnesses the power of specific wavelengths of light, particularly in the red and near-infrared spectrum, to stimulate cellular processes such as ATP production, enhance mitochondrial function, reduce inflammation, promote tissue repair, and modulate biological responses like gene expression and ion channel activity. These benefits make near-infrared light a versatile tool in PBM, with applications ranging from athlete recovery and performance improvement and pain management to potential treatments for complex neurological conditions.

My unique perspective, combining over two decades of nursing experience with expertise in cutting-edge PBM technology, has allowed me to bridge the gap between clinical practice and sports medicine. This is evident in my recent work, including an abstract accepted by the American Society for Laser Medicine and Surgery (ASLMS) for E-Poster Presentation on Transcranial PBM for treating neurodegenerative diseases.

As the field of PBM continues to evolve, I remain committed to advancing its science and application in sports medicine. We are opening new frontiers in athletic performance and recovery, providing athletes with safe, effective, and non-invasive methods to optimize their potential.
