Figure S1. Voluntary anorectal functions were obtained three times before and after enhanced instruction. The effects of repetition and instruction are shown on (a) squeeze pressure (b) squeeze duration (c) intra-rectal pressure (d) recto-anal pressure gradient. A stepwise (not a progressive) improvement in function is observed in each parameter following the intervention. Thus, it is the enhanced instruction and verbal feedback that produces the observed effect and not the repetition of these maneuvers.
