The<unk>  is a reflex that occurs when one attempts to move a limb against resistance that is suddenly removed. When the resistance is removed, the limb will usually move a short distance in the original direction, at which point the antagonist muscles will contract, causing the muscle to yank back in the opposite direction. The<unk>  will be present in limbs unaffected by disease or illness, and strongly exaggerated in limbs exhibiting signs of spasticity. A complete absence of the<unk>  (that is, a failure of the antagonist muscles to contract) may indicate the presence of cerebellar disease. Therefore, an awareness of the<unk>  can assist in the diagnoses of both types of disorders. The<unk>  was first described by Gordon Morgan<unk>  and Thomas Grainger Stewart in a paper published in 1904, though it was not named until a 1917 paper published by<unk> .
