摘要

The second concern was regarding pelvic floor muscle training side effects. The systematic review cited by Mr Ariie included 21 trials involving 1281 women (665 pelvic floor muscle training, 616 controls).? From these trials, only one reported adverse events with pelvic floor muscle training.’ This specific trial included 66 participants, among whom only four mentioned side effects related to treatment: ‘one mentioned pain and three an uncomfortable feeling during the exercises’. It is unclear whether the pain and discomfort was caused by the pelvic floor muscle training itself; it could be related, for example, to the women’s posture during the exercise. Considering this information from the available trials related to this topic, we believe that it is unlikely that there are significant side effects of pelvic floor muscle training. However, we agree that side effects should be investigated, reported and better discussed in future studies.
