Near-Infrared Light for Anti-Primary Dysmenorrhea
Bypassing the Heat Risk and Efficacy Limitations of Pulsed 630 nm LED Photobiomodulation Therapy for Anti-Primary Dysmenorrhea: A Prospective Randomized Cross-Over Trial
Study Overview
Description: A prospective randomized cross-over trial to assess the efficacy and safety of pulsed 630 nm LED light for primary dysmenorrhea.
Source: MDPI
Summary
Focus: 40 women with primary dysmenorrhea
Intervention: Pulsed 630 nm LED light (50 Hz, 40% duty cycle, 25mW/cm2 peak, 10mW/cm2 average, 12 J/cm², 20 min daily for 7 days) applied to acupuncture points. Control was a placebo treatment.
Methods: Measurement of pain (VAS) and quality of life
Conclusion
Pulsed 630 nm PBM at 50 Hz is effective and safe for reducing menstrual pain and improving quality of life in women with primary dysmenorrhea
