Drop foot has a variety of causes and different ways to approach those casues. The common symtom seems to be not lifting toes as you walk even though your brain thinks they are being lifted. Pain with drop foot seems to vary from really bad to little or none. Keeping your balance while standing is part of it. In my case, I attribute my lack of much pain is taking collagen on a daily basis. With drop foot support is needed to keep the toes up. I have braces inside each shoe to keep the toes up. I wear shoes with a soft sole and support in the sole and use a cane inside to help when I stumble and walking sticks on uneven ground outside. An ankle sleeve with an attachment to the middle or front of the shoe probably would work and be much cheaper.
I am trying to get my toe and akle muscles to react better to my brain again. I have tried acupuncture, shock wave (softwave) treatments, redlight/infrared (Rebuilder sleeves and LZR Ultrabright) treatments. Currently going through Sanexas treatments and PT treatments using a Tens/NMES with exercises.
1.5 years of treating dropfoot (I will be 74 later this year) has improved my drop foot to where I can use my right foot to controll both the brake and gas when I drive - used left foot to brake early on. My walking speed (with walking sticks) has speeded up to where I can keep up with people walking at normal walking speeds. It is not getting worse and the improvements are very slow in coming.
