Strengths and limitations
Strengths of the study were the randomized and assessor-blinded design, concealed allocation, a supervised individually tailored program for each participant aiming at treating the symptoms and high adherence to the exercise sessions. Following the participants for one year should also be considered a strength, as long term results are lacking in published studies.12
Limitations were the higher drop-out rate in the TG and the low number of women reporting prolapse symptoms in both groups which may have caused a type II error due to small sample size. Five women who were randomized to the TG and contributed to the main outcomes did not participate in the intervention, which also might have influenced the results. The adherence to PFMT after cessation of the intervention is also a limitation of the study.
