Postural asymmetries following unilateral subthalomotomy for advanced Parkinson's disease


  • A videotape accompanies this article.


Two cases of postural asymmetries following unilateral stereotaxic subthalamotomy were observed with head and body tilting to the side contralateral to the STN lesion, which corrected itself completely or partially with levodopa treatment. After subsequent contralateral STN surgery, the postural asymmetry disappeared in both patients. Possible mechanism is discussed. © 2002 Movement Disorder Society.
