Abstract:

The main symptoms of dyssynergic defecation are difficult defecation and incomplete emptying， and may also be accompanied by anal swelling， pain， manual assisted defecation， urination and sexual dysfunction， etc. Patients often have poor effects on conventional treatment such as laxatives. Biofeedback therapy is an emerging therapy for dyssynergic defecation in recent years. The researches of dyssynergic defecation in recent years show that patients' symptoms can be effectively improved by monitoring pelvic floor muscle activity and providing real-time feedback. With the continuous progress of technology， the accuracy and portability of biofeedback therapeutic equipment has gradually improve， making it more convenient and effective in clinical application. However， the single biofeedback effect is slow， which easily affects the patient's treatment confidence. At the same time， the study has found that biofeedback therapy can be combined with other treatment methods to achieve better efficacy. This paper reviews the efficacy status of biofeedback combination therapy at home and abroad， and discusses the biological mechanism and their respective effects， in order to provide more effective treatment options for patients with dyssynergic defecation.
