Relevance – It is not fully understood whether nonmotor features are affected in all patients with PD and at what age.

Subjective visual vertical perception and sense of smell in Parkinson disease. J Rehabil Res Dev. 2012;49(6):961–70. http://dx.doi.org/10.1682/JRRD.2011.05.0090 7 Slideshow Project DOI:10.1682/JRRD.2011.05.0090JSP Methods Open cross-sectional observational study. – 47 participants with PD. – 47 age- and sex-matched nondisabled controls. All participants completed: – Computerized rod and frame (CRAF) test. To examine perception of SVV. – 12-item University of Pennsylvania Smell Identification Test. To examine olfactory perception.

Subjective visual vertical perception and sense of smell in Parkinson disease.

Untilted frame in CRAF: – PD participants and controls significantly differed. Tilted frame in CRAF: – PD participants and controls did not significantly differ. No. correctly identified odors and individual’s SVV error: – No significant correlation. Mini-Mental State Examination score and time to complete CRAF in PD participants: – Significant negative correlation.
