title: Spatial disorientation in Parkinson's disease: no effect of levodopa substitution therapy.
abstract: In 22 patients with idiopathic Parkinson's disease, we tested spatial orientation with the rod orientation test, before and after levodopa substitution therapy was started. In both situations an impairment of spatial orientation could be demonstrated: levodopa did not improve this impairment.
