- Partial or total inability to dorsiflex the foot, as a consequence of which the toes drag on the ground during walking unless a steppage gait is used; most often ultimately due to weakness of the dorsiflexor muscles of the foot (especially the tibialis anterior), but has many causes, including disorders of the central nervous system, motor unit, tendons, and bones.
* * *foot·drop (footґdrop) dropping of the foot from a peroneal or tibial nerve lesion that causes paralysis of the anterior muscles of the leg; see also steppage gait. Called also dangle foot and drop foot.
