PD Screening Instruments & Scales

Parkinson’s Disease Rating Scales

Several rating scales have been developed to measure the impact of PD on a patient and family. These scales are used in research to determine eligibility to participate in a research trial or to assess severity and disease progression. Scales may also be used in clinical practice to identify and monitor problems or gauge clinical function and degree of progression.

MDVU (Movement Disorder Virtual University) brought to you by WE MOVE, offers online PDF rating scales and scoring sheets as well as CME courses.
