La eficacia de la acupuntura para el tratamiento de la fibromialgia: revisión sistemática y meta-análisis de ensayos aleatorios.

OBJECTIVE:

The study sought to ascertain the effectiveness of acupuncture as a treatment for fibromyalgia

MATERIALS AND METHODS:

The following electronic databases were searched: PubMed; The Cochrane Library (CENTRAL); EMBASE; CINAHL; and Pascal Biomed (last date of search: January 2008). We analyzed pain intensity and patient withdrawals prior to termination of the study. A meta-analysis was performed, and a weighted global effect obtained using the inverse of variance.

RESULTS:

This review covered a total of 6 studies (323 subjects). No statistically significant differences were observed in terms of pain intensity (VAS)= 0.02 (-0.24 a 0.28) or withdrawals: RR 0.91 (0.53 a 1.58).

CONCLUSION:

This systematic review found no evidence of benefit resulting from acupuncture versus placebo, as a treatment for fibromyalgia.
