In looking over comments to one of the many Trump posts today, a commenter posted a video that I assume is from Trump’s visit to a Fujifilm biotech plant in North Carolina this past Monday (it’s not just film and cameras anymore, Martha and Melvin...). The clip shows Trump dragging his right foot leading with the toe. This could be a condition called foot drop or drop foot. (If someone has that video, please post it—thanks.) If Trump does have foot drop, it could explain both his physical condition (his unannounced visit to Walter Reed last November), and, potentially, his deteriorating mental condition.
The Mayo Clinic has a nice write-up about foot drop (www.mayoclinic.org/...). The condition is typically exhibited in just one leg, but can be in both. As noted above, the toe of the affected leg/foot seems to stay on or near the floor but the heel may still rise. In the video, Trump’s toe even has a slight outward push away from his body, but the heel stays roughly (well, okay, very roughly) where in should in relation to the other leg as he walks.
Foot drop would also explain his problem going down the ramp at the West Point graduation ceremony. His left leg wanted to do the normal walking but his right leg had a mind of its own. (Please! No jokes about his appendages having minds of their own.)
There are numerous conditions that may cause foot drop. But, In short, it could be from a number of causes, such as stroke (which many suspect Trump suffered), another neurological issue or different medical problems, ranging from muscular dystrophy to multiple sclerosis and other ailments.
In the past, presidents have been loathe to reveal their more severe medical problems. Think Franklin D. Roosevelt with his polio, John F. Kennedy with his painful back and other conditions, Woodrow Wilson with a stroke causing partial paralysis, Eisenhower had lots of medical problems (appendix, heart, Crohn’s, et al.), and, of course, Ronald Reagan with Alzheimer’s. Still, when a condition can affect both physical and mental abilities, and the person’s ability to carry out his or her duties to the American people, the public should be informed. And that would apply to any president or candidate.
