1. Is the human stretch reflex cortical rather than spinal?;Marsden, C.D.; Merton, P.A.; Morton, H.B.;Lancet,1973
2. Myotatic reflexes and the on-off effect in patients with Parkinson's disease;Dufresne, JR, Soechting; JF, Tolosa; E.S.;J Neurol Neurosurg Psychiatry; 44: ease,20 also may contribute to increased muscle stiffness. At present we have not obtained enough detailed data to enable us to separate out these individual contributions. However, the average group results suggest that, when evaluated using servocontrolled positional displacements, stretch reflex size may be a useful objective physiological measure of Parkinsonian rigidity,1981
