Is there a cure for foot dragging?

Neuropathy: It depends on the cause. Foot dragging usually caused by injury to nerve going to your leg, either the peroneal nerve or injury to nerve coming from the 5th nerve in your lower back. Recovery depends on whether traumatic, or other cause for the injury.

Possibly: So this is foot drop and it would depend why you have it. If there is a nerve impingement going on in your back which is surgically released, it can be corrected. If it is status post a stroke, chances are damage has been done already and for the most part this is permenant. You should see a neurosurgeon or orthopedist who handles this kind of work.

Strengthen or assist: Dragging is from a lack of ankle dorsiflexion. This is for example present in a drop foot associated with a neurological disorder. Strenghteing the anterior tibial muscle (see internet) could help. If this continues, there are dorsiflex assisted braces but before that, simple ankle braces or high top shoes should help.

Possibly: Need to determine the cause of the drop foot. Injury to common peroneal nerve in the leg, stroke, lower back impingement (pinching) of the nerve leading to the lower leg. See a neurosurgeon or spine orthopedist accordingly.
