Photobiomodulation in Parkinson's disease: A randomized controlled trial

Published:February 20, 2019DOI:https://doi.org/10.1016/j.brs.2019.02.009
      Photobiomodulation, which uses non-thermal and non-ionizing light in the visible and infrared spectrum, has been proposed as a potential strategy for improving the symptoms of patients with Parkinson's disease (PD) [

      ], but this has not been tested in a randomized controlled trial (RCT). We thus sought to assess whether photobiomodulation can ameliorate the cardinal motor symptoms of PD using an RCT design.
