Botulinum toxin type A injection combined with biofeedback in the treatment of spastic pelvic floor syndrome

Figure 1 Biofeedback treatment diagram. The light blue line indicates the simulated contractile anal muscle strength; the red line indicates the actual anal muscle strength of the patient. The dark blue line indicates the abdominal muscle electromyography of the evaluator; the yellow line indicates the abdominal muscle strength threshold.

Figure 2 Comparison of the incidence of the prevalence of constipation-related symptoms before and after operation. A: Manual defecation before and after operation; B: Defecation blockage before and after operation; C: Straining blockage before and after operation.

Figure 3 Anorectal pressure distribution map of patient during simulated defecation. The red arrow indicates areas that simulate contradictory contractions during defecation where the anal sphincter cannot relax.
