As requested in the letter by Marsden and Duvoisin, we report further clinical notes on our patient described in the Archives (36:246-248, 1979). Rigidity, tremor, and akinesia first appeared on the right side, and the severity of the disease had always been prevalent on the same side. In the untreated state, the patient showed a lean of the trunk directed ipsilaterally to initial and major parkinsonian symptomatology. Scoliosis was not found on roentgenologic examination of the spinal column.The asymmetrical posture with lean to the right side was more apparent when the patient was standing or sitting in a chair for a long period. In these conditions, the patient never showed a tendency to slump to the left, as expected by Marsden and Duvoisin.It is important to note that the abnormalities of motor behavior (twisting movements and falling to the right side) started in the patient after long treatment
