Prospective Evaluation of Forceplate Measured Levodopa-Induced Dyskinesia
Prospective Evaluation of Forceplate Measured Levodopa-Induced Dyskinesia
Nearly all Parkinson's disease (PD) patients eventually develop abnormal and unwanted
 movements (dyskinesias; LID) caused by the gold standard treatment, Levodopa. The severity of
 these movements can range from subtle to extremely debilitating and may or may not interfere
 with normal activities such as putting on a coat or brushing ones teeth. The purpose of this
 study is to demonstrate the validity and reliability of objectively measuring dyskinesia with
 a forceplate.
The main outcome measure of this study are measurements taken every half hour during an
 inpatient study visit. These measurements include standing on a forceplate for 1 minute while
 performing a mental task such as reciting the alphabet backwards. During this forceplate
 stance, a rater will visually score your movements. All participants must be eligible for
 another Parkinson's disease study at Oregon Health and Science University.
