I was terrible at doing Kegels after surgery. I remembered to do them maybe 4-5 times a week. I was dry at 9-10 weeks.
I walked, certainly, but just walked around, not like miles a day.
I think all these things certainly will help, but the normal progression is dry at night, the dry in the morning, then the afternoon. Then, the last to disappear is the leaking in the evenings.
My nurse acknowledged that the Kegels might help, but there is no proof. She also thought it was good to give the patient something to work on to give them a sense of control and purpose and a sense of having some role in the recovery - whether it does or not, it will help mentally, emotionally, and physically to walk.
Oh, - suppose I should mention that I do much more than walking. I go to my gym several days a week and do cardio and weight machines - high reps, moderate weights. EVer since back surgeries, I've had to keep good muscle tone.
