Objectives: Available literature highlights the effectiveness of Acupuncture or Acupressure on the Spleen 6 acupoint ( or SP-6) for pain management in primary dysmenorrhea (PD). The objective of the current systematic review and meta-analysis is to provide an updated assessment of available randomized and non-randomized controlled trials and to compare the effectiveness of acupressure and acupuncture stimulation of among patients with PD.
Methods: We conducted a comprehensive literature search on various electronic databases including Embase, PubMed, and the Cochrane Library from January 1990 to March 2023 to identify the comparative studies (randomized and non-randomized controlled trials) that assessed the effects of acupressure or acupuncture on the acupoint in patients with PD.
