There seems to be no limit to the health problems that respond to chiropractic care. How many people suffering, on drugs, facing a life of limitation could be helped by chiropractic care? 

Probably most of them.

Foot drop

A 24-year-old male weight lifter presented with insidious onset of foot drop upon waking from bed. There were no preceding signs or symptoms prior to the foot drop. The pain was intolerable and pressure could not be applied while standing. He went to the hospital emergency department the morning the initial symptoms appeared. All medical testing and imaging were negative.

He then followed up with the chiropractic clinic and following an exam and adjustments his symptoms began to diminish. After four visits the patient had complete resolution of all signs and symptoms. (1)
