COVID-19 Pneumonia Patient significantly Improves with Laser: Case report

Prior to treatment, the patient was bedridden with a severe cough and inability to ambulate. Upon completion of treatment, the patient's cough resolved, and he was able to ambulate with physical therapy. On the following day, he was discharged to an acute rehabilitation facility on minimum supportive oxygen. Just one day later, the patient was able to complete two trials of stair climbing with physical therapy and was in the process of weaning to room air. On follow-up, his clinical recovery in total was three weeks, whereas the median time is typically six to eight weeks.

"Adjunct Photobiomodulation Therapy effectively treated respiratory symptoms in a severe case of COVID-19 pneumonia. We consider this therapeutic option to be a feasible supportive treatment modality," said Dr. Sigman. "There is continued medical need for more safe and effective COVID-19 treatment options. We are hopeful that this report and subsequent study will encourage others to consider additional clinical trials with the use of adjunct PBMT for COVID-19 pneumonia."

In PBMT, light is applied over damaged tissues, and light energy is absorbed by cells starting a cascade of molecular reactions that improve cell function and enhance the body's healing process. PBMT has demonstrated anti-inflammatory effects and is emerging as an alternative modality in pain management, lymphedema treatment, wound healing and musculoskeletal injuries. The utilization of supportive PBMT for COVID-19 is based on the theory that the laser light reaches the lung tissue to relieve inflammation and promote healing. Additionally, PBMT is non-invasive, cost-effective, and has no known adverse effects.

The MLS laser uses a mobile scanner with 2 synchronized laser diodes, one in pulse mode (adjustable to 1–2000 Hz), emitting at 905 nm, and another in pulsed mode emitting at 808 nm. The two laser wavelengths work simultaneously and are synchronized. The laser is placed 20 cm above the patient across the lung fields while in the prone position. The laser is painless, and patients typically are unaware that the laser treatment is occurring. This laser is routinely used for deeper tissues like hips and pelvic joints that are surrounded by thick muscles. The therapeutic dose used to reach the deep targets of the pelvis is 4.5 J/cm2. Based on calculations by Dr. Soheila Mokmeli, co-author of the study, 7.2 J/cm2 was used over the skin, delivering a therapeutic dose just over 0.01 J/cm2 of laser energy to the lung. This dosage is able to penetrate the chest wall and reach the lung tissue creating an anti-inflammatory effect that in theory blocks the effects of the cytokine storm seen in COVID-19 pneumonia.
