1951 Lancet 24 Feb. 430/2 Well-marked tremor was present in the tongue, jaw, and right arm and leg, with typical cog-wheel rigidity, a flexed posture, and a tendency to propulsion and retropulsion.

2008 Movement Disorders 23 2224 A neurological syndrome characterized by levodopa unresponsive bradykinesia, retropulsion with falls backwards, dysarthria, gait disturbance, dystonia, and emotional lability was identified in 13 male opiate addicts following the prolonged intravenous use of ephedrone.
