EMS after lipo: Is it beneficial with all other aftercare? How long would I have to wait before starting EMS on lipo'd stomach?

Hi, I am getting liposuction done on my abdomen next month, I have not had a chance to ask for doctor and will but wanted to hear a couple of opinions of the use of EMS (electrical muscle stimulation) 1. Do you think it could be beneficial after liposuction of the abdomen along with all other after care? 2. How long would I have to wait before starting EMS treatment on liposuctioned stomach. Thank you
