A common behavioral cause of foot drop is habitual crossing of the legs. These cases typically resolve with discontinuance of the habit.

Neurologic causes of foot drop include mononeuropathies of the deep peroneal, common peroneal, or sciatic nerve. Lumbosacral plexopathy, lumbar radiculopathy, motor neuron disease, or parasagittal cortical or subcortical cerebral lesions also can manifest as foot drop. These lesions can be differentiated by means of clinical and electrodiagnostic examinations.

Foot drop also may be seen as a combination of neurologic, muscular, and anatomic dysfunction. Charcot foot is one example.
