[Effect of the position of the body in space on the dynamics of tendon reflexes in stroke patients during the rehabilitation period].
Chronometry of Achilles reflexes in 40 healthy subjects and 25 patients in the recovery period after cerebral stroke with regard to body posture showed that in normal subjects the vertical position was associated with a reduced time of the reflectory response whereas in the patients it was increased. It is assumed that a change in the speed of tendon reflexes in different postures is related to the readjustment of suprasegmental and afferent influences on the segmental apparatus of the spinal cord.
