Near-infrared photobiomodulation therapy for rehabilitation of patients with long COVID

ABSTRACT

About 80% of the patients recovering from COVID-19 have inflammation symptoms, like brain fog, myopathy, myalgia, muscle weariness, headache, mental tiredness, asthenia, adynamia, dizziness, tinnitus, hearing loss, telogenic effluvium and mood disturbances. Here, we demonstrate how transcranial and systemic photobiomodulation using near-infrared LEDs emitting 850 nm wavelength light enhanced cognition and reduced pain. Participants were separated into transcranial photobiomodulation with near-infrared LEDs (850 nm, 10W, 10 minutes), photobiomodulation with a punctual cutaneous application (850nm, 10W, 10-40 minutes), and both treatments. All patients underwent 10-day treatments at least. © 2023 SPIE.
