Abstract: Objective To evaluate the effectiveness of biofeedback for anxiety patients by carrying out a Meta-analysis.Methods We searched CNKI,VIP,CBM(1989 to 2013) to identify relevant randomized-control trials applying biofeedback for anxiety patients.We used Review Management (RevMan) 5.0 software (provided by the Cochrane collaboration) to conduct Meta-analysis.Results We included 11 studies.Meta-analysis for the biofeedback group vs.the control group showed that biofeedback was significantly superior to control (SMD=-3.00,95％CI:-4.40～-1.61); Meta-analysis for the biofeedback plus drug group vs.drug group showed that biofeedback plus drug was significantly superior to drug (SMD=-1.33,95％CI:-1.82～-0.85).Conclusions We found evidence that biofeedback (applying alone or combined with drugs) is effective in improving anxiety symptom.But all the studies had methodological limitations,our conclusion needs further studies with strict design,high quality and consistent assessment tools to be expounded and proven.
