I did not get much help from Mayo, the neurologist that gave me the path to improvement is at Barrow Brain and Spine. The EMG will give you a baseline against which you can measure improvement in the future. It is an unpleasant test to go through but it becomes your baseline. PT needs to focus on strengthening both legs so your strength aims to even out. I totally relate to your comment of gripping the rail for dear life and the difficulty in clearing the curb. It is tough!
