Adherence to aerobic exercise was good, with high attendance at sessions (93%), a strong compliance to exercise duration (95%) but lower compliance to the prescribed intensity (73%). After the program, more patients were able to walk independently in the training group ( n\u2009=\u200918) compared to control ( n\u2009=\u200913) ( P\u2009&lt;\u20090.05).
