Treatment of Women With Primary Dysmenorrhea With Manual Therapy and Electrotherapy Techniques: A Systematic Review and Meta-Analysis.

OBJECTIVE

The objective of this study was to evaluate the efficacy of electrotherapy and manual therapy for the treatment of women with primary dysmenorrhea.

METHODS

Systematic searches were conducted in Scopus, Web of Science, PubMed, CINAHL, and MEDLINE. The articles must have been published in the last 10 years, had a sample exclusively of women with primary dysmenorrhea, had a randomized controlled trial design, and used interventions that included some form of manual therapy and/or electrotherapy techniques. Two reviewers independently screened articles for eligibility and extracted data. Difference in mean differences and their 95% CIs were calculated as the between-group difference in means divided by the pooled standard deviation. The I2 statistic was used to determine the degree of heterogeneity.

RESULTS

Twelve selected studies evaluated interventions, with 5 evaluating electrotherapy techniques and 7 evaluating manual therapy techniques. All studies analyzed identified improvements in pain intensity and meta-analysis confirmed their strong effect.

CONCLUSIONS

Manual therapy and electrotherapy are effective for the treatment of women with primary dysmenorrhea. Transcutaneous electrical nerve stimulation combined with thermotherapy and effleurage massage stands out for its effects on the intensity and duration of pain with the application of a few sessions and their long-term effects.

IMPACT

Manual therapy techniques and electrotherapy methods reduce the pain intensity of women with primary dysmenorrhea. Quality of life and degree of anxiety improved significantly with manual therapy interventions. Transcutaneous electrical nerve stimulation combined with thermotherapy and effleurage massage are the interventions with which positive effects were achieved with fewer sessions.
