The following video shows how my gait has been affected by an MS symptom called "foot drop." The phrase means just what it sounds like. Foot drop is when the front of the foot falls behind and tends to drag on the ground. Since I have relapsing remitting MS, this particular symptom comes and goes for me. But for others this can be a more permanent problem. Although there can be other causes for this particular symptom other than Multiple Sclerosis, it is always wise to get such a symptom checked out by your doctor.
And before you ask, this video was shot several months ago when it was a whole lot warmer!
