Laser phototherapy parameters
Coherence infra-red laser treatment (650 nm) was administered to individuals in the experimental group only using a laser wristwatch (LASPOT, Wuhan, China). The laser watch stimulated specific wrist acupuncture points while simultaneously releasing two nasal laser beams using two nasal probes (radiated both ulnar and radial arteries, the middle wrist acupoints)The Laser Watch's operational parameters were monochromatic 650 nm wavelength, energy (8.64 J), spot size (0.03 cm
