Drop foot is a very common MS symptom so it gets a lot of attention as far as treatment options. Like any other symptom, it should go away in time with or without the use of steroids. If it persists however, there are a few things you can do to make walking easier. Most commonly used is an AFO (Ankle Foot Orthosis) which is a flexible plastic brace that fits under your foot and straps around your lower shin to keep your toes pointed upwards enough to allow you to walk. Most AFO’s are discreet enough that they fit comfortably inside your shoe and remain hidden under your pants.
You’re just going for a simple walk around the neighborhood, something you have done every day for as long as you can remember. All of a sudden you trip. You look around to see what caused you to stumble to find nothing but clean sidewalk. You keep on walking; it happens again! After a few days this keeps happening more and more frequently; you trip over your own foot. Soon you realize that your foot is constantly dragging. You take a step forward but your toes don’t lift up off the ground and instead slide across the floor. This is called drop foot (or foot drop).=&0=& There is a muscle on top of the foot called the Extensor Digitorum Brevis muscle which is in charge of lifting the toes upwards (this motion is known as dorsiflex). When you take a step this muscle should activate lifting the toes up and away from the ground but when you’re experiencing drop foot it fails to do this leaving the toes limp. Since they are not being pulled up and away from the ground they drag into it which can cause you to trip. Why is this muscle not activating properly? Well, Multiple Sclerosis attacks the Myelin sheath around your nerves which affects their conductivity. Somewhere along the path that the electrical signal must flow from your brain to your foot to activate that muscle is a lesion preventing the signal from reaching the Digitorum Brevis muscle in charge of lifting your toes. This results in what is called foot drop. =&1=&Read more
