BACKGROUND: @entity1209 in pregnancy (NVP) and @entity7494 gravidarum (HG) have a significant impact on quality of life. Medication to relieve symptoms of NVP and HG are available but pregnant @entity1 and their caregivers have been concerned about the teratogenic effect, side effects and poor efficacy. The aim of this review was to investigate if there is any clinical evidence for the efficacy of acustimulation in the treatment of NVP or HG. METHODS: A systematic review of randomized controlled trials (RCTs), including both English and Chinese databases was conducted to assess the efficacy of various techniques of acustimulation for NVP and HG. The methodological quality of the studies was assessed using the Cochrane's risks of bias tool. Revised STRICTA (2010) criteria were used to appraise acustimulation procedures. Pooled relative risks (RRp) and @entity5494 ( @entity5494 ) with 95  % confidence intervals (CI) were calculated from the data provided by the investigators of the original trials. RESULTS: Twenty-nine trials including 3519 @entity1 met the inclusion criteria. Twenty trials could be included in statistical pooling. The overall effect of different acustimulation techniques shows a significant reduction for the combined outcome for NVP or HG in pregnancy as a dichotomous variable ( @entity19107 .73, 95  % CI 1.43 to 2.08). Studies with continuous outcome measures for @entity390 , @entity391 and the combined outcome did not show any evidence for relieving symptoms of NVP and HG ( @entity5494 -0.12, 95  % CI -0.35 to 0.12). CONCLUSIONS: Although there is some evidence for an effect of acustimulation on @entity390 and @entity391 or @entity7494 in pregnancy, results are not conclusive. Future clinical trials with a rigorous design and large sample sizes should be conducted to evaluate the efficacy and safety of these interventions for NVP and HG.
