The Moro reflex: insights into the pathophysiology of generalized tonic-clonic seizures and infantile spasms Volume 24, numéro 5, October 2022

Adult with primary generalized (clonic)-tonic-clonic seizure. At the onset of the seizure, the arms are suddenly elevated and abducted with flexion at the elbows and palms facing forward. The abduction and elevation of the arms are reminiscent of the proximal movements seen in the first component of the MR (and in epileptic spasms). However, unlike the MR (in which arm flexion at the elbows can occur after arm extension), at the onset of generalized tonic-clonic seizures, the elbows are semi-flexed. The flexion of the legs is a further feature that is not typical of the MR. The seizure is shown twice, first at normal speed and then in slow motion.
