Brief Summary: The primary objective of this study is to determine whether intramuscular injections of botulinum toxin type A (Botox®) in selected cervical muscles at antidystonic dosages can reduce levodopa-induced peak-dose dyskinesias (LID) in the cervical region in adult patients with idiopathic Parkinson's disease. It is hypothesized that the intramuscular injection of antidystonic doses of botulinum toxin into cervical muscles will decrease the duration and severity of LID in the cervical region in patients with Parkinson's disease (PD).
Detailed Description: The study will follow a cross-over design to maximize statistical power and decrease biases inherent to small samples as patients will become their own controls. After a baseline assessment, patients will be randomized to receive either botulinum toxin or an equal amount and distribution of normal saline (placebo). Patients will undergo reassessment of function at one and four weeks after the initial and second session of injections. The second procedure will occur, using the opposite treatment arm (Botox® or saline placebo), three months after the first injection session. Doses of levodopa, dopaminergic agonists, and antidyskinetic drugs if applicable, will be kept constant throughout the study. All study assessments will be carried out at the time treatment is expected to cause the greatest severity of LID.
