The in vitro study, led by Patricia A. Trimmer, PhD, associate professor of neurological research at the UVA School of Medicine, showed that a single, brief treatment with a 810 nm low level, near-infrared laser increased for two-hours the velocity of mitochondrial movement in cells taken from patients with sporadic Parkinson’s disease, speeding it up to levels comparable to cells from a disease-free, age-matched control group.
