Foot Drop refers to the inability to dorsiflex (lift) the toes or foot. Foot drop, also known as drop-foot, can be a temporary or permanent condition. The condition can be dependent upon the extent of paralysis or muscle weakness that is present. Occurring in either one foot or both feet, foot drop can have many causes such as common fibular nerve damage, sciatic nerve damage, paralysis of muscles in the anterior portion of the lower legs, abnormal anatomy, muscle or spinal cord trauma…
