Effectiveness of GV20-based wearable low-level laser acupoint therapy for pain on head.

The effectiveness of GV20-based Wearable Low-level Laser Acupoint Therapy for pain on right temporal head was investigated. The study was designed as a triple-blinded, randomized controlled clinical trial. The deep pressure pain targeted by 300g monofilament and Visual Analog Scale (VAS, 0-10) scores on right temporal head were assessed were randomly assigned to wearable LLLAT (650 nm, 5 mW, 30 min, about 9 joule each acupoint) on Baihui (GV20) with four Sishencong (EX-HN1) or sham group (n=24 vs 24). The mean VAS pain scores in wearable LLLAT group after GV20 with EX-HN1 acupoint treatment were significantly decreased comparing with sham group. This trial suggested that wearable Low-level Laser Acupoint Therapy 650 nm 5 mW for 30 min each acupoint simultaneously could effectively reduce deep pressure pain on temporal head.
