Laser acupuncture does not improve menopausal symptoms

Area of Science:

• Integrative Medicine
• Gynecology
• Complementary and Alternative Medicine

Background:

• Acupuncture is a common treatment for menopausal and gynecological issues.
• Laser acupoint stimulation offers a noninvasive, reproducible, and convenient alternative.
• Previous studies on conventional acupuncture suggest potential benefits for menopausal symptoms.

Purpose of the Study:

• To evaluate the efficacy of laser acupoint stimulation in alleviating menopausal symptoms.
• To compare active laser acupoint stimulation with a placebo control in women experiencing menopause.

Main Methods:

• A double-blind, randomized, placebo-controlled trial involving 40 women with active menopausal symptoms.
• Participants received either active or placebo laser acupoint stimulation every two weeks for 12 weeks.
• Outcomes included diurnal/nocturnal hot flashes and a validated symptom score; a sham laser device simulated active treatment.

Main Results:

• No statistically significant differences were observed between the active laser and placebo groups.
• The number of diurnal and nocturnal hot flashes did not differ between groups.
• Non-flushing symptom scores also showed no significant improvement with active laser treatment.

Conclusions:

• Laser acupoint stimulation, using a standardized set of acupoints, demonstrated no superior efficacy over placebo.
• The treatment was not more effective than stimulation with an inert laser probe for altering menopausal symptoms.
• Further research may be needed to explore other parameters or patient populations.
