The "Buckets": Early Observations on the Use of Red and Infrared Light Helmets in Parkinson's Disease Patients.

Parkinson's disease is a well-known neurological disorder with distinct motor signs and non-motor symptoms. We report on six patients with Parkinson's disease that used in-house built photobiomodulation (PBM) helmets. We used "buckets" lined with light-emitting diodes (LEDs) of wavelengths across the red to near-infrared range (i.e., 670, 810, and 850 nm;  = 5) or an homemade intranasal LED device (660 nm;  = 1). Progress was assessed by the patients themselves, their spouse, or their attendin...

Combined Effectiveness of β-Cyclodextrin Nanoparticles in Photodynamic Antimicrobial Chemotherapy on In Vitro Oral Biofilms.

This study aimed to investigate if β-cyclodextrin nanoparticles potentiate the photodynamic antimicrobial chemotherapy (PACT) effects in single and microcosm oral biofilms using methylene blue (MB) and a red laser. Studies of PACT have demonstrated promising effects; however, the association of nanoparticles with photosensitizers could enhance the antimicrobial result. Biofilms were grown on enamel blocks either with or in a microcosm model (salivary microorganisms) supplemented with sucrose. PACT using...

Feeling the Heat: Evolutionary and Microbial Basis for the Analgesic Mechanisms of Photobiomodulation Therapy.

The clinical therapeutic benefits of Photobiomodulation (PBM) therapy have been well established in many clinical scenarios. However, we are far from having developed a complete understanding of the underlying mechanisms of photon-biological tissue interactions. Concurrent to ongoing PBM studies, there are several parallel fields with evidences from cell and tissue physiology such as evolutionary biology, photobiology, and microbiology among others. This review is focused on extrapolating evidences from an...

Applications of Photobiomodulation Therapy to Musculoskeletal Disorders and Osteoarthritis with Particular Relevance to Canada.

Musculoskeletal disorders caused by osteoarthritis (MSDs/OA) are a growing problem in the modern industrialized society in Canada. Overall aging of the general population and a progressive lack of exercise contribute to this alarming increase. Moreover, a range of chronic conditions including cardiovascular and mental diseases show significantly higher comorbidity with MSDs/OA. Conventional medical treatment for MSDs/OA includes nonsteroidal anti-inflammatory drugs and opiate pain killers. These drugs have ...
