I don't know what an "ab Board" is, but in my opinion you should wear the type of compression garment your surgeon recommends.
Thanks for your question.I do not recommend my patients to have lipo form after tummy tuck.They are asked to wear binder or compression garment for 4-6 weeks.Since each plastic surgeon can differ in our surgical and post-surgery protocol, it would be best to check with your plastic surgeon.Best regards.
