Chapter 4 106 DRE by the pelvic floor physical therapist versus BET (n=37) Results are almost similar with the DRE by the surgeon. S-EMG versus TPUS (n=32) Twelve patients (37%) showed the same results concerning classifying the puborectalis muscle movement in these tests (Table 9). Table 9.

One patient evacuated the gel completely during TPUS but showed an increase in electric activity with the s-EMG. This patient did not show paradoxical movement on the other tests. Table 10.

TPUS was often classified as ‘indifferent’ in 25 (78%) patients.
