A condition in which the foot cannot be raised properly and hangs limp from the ankle. Neuritis affecting the nerves that supply muscles that move the foot is a common cause and may be due to diabetes mellitus, multiple sclerosis, or a neuropathy. Weakness in the foot muscles can also result from pressure on a nerve (due to a disc prolapse or a tumour) as it leaves the spinal cord. Treatment is of the underlying cause, but in many people the weakness persists. A lightweight plastic caliper splint can be used to keep the foot in place when walking.
