Statistical Analysis
Statistical analysis was performed using SPSS, version 12.0
(SPSS, Chicago, IL). Student’s t test and the chi-square test
were used to compare both groups preoperatively, before exercise,
and after exercise for functional physical fitness and continence
status. The measurements were compared using a paired
t test for continuous parameters and the McNemar test for
categorical parameters to determine a change from preoperative to before exercise and from before exercise to after exercise in
quality of life and depression. All tests were 2-sided, with P
.05 considered statistically significant.
