About

The objective of this study is to evaluate the effectiveness of Deep Brain Stimulation as an adjunctive treatment for reducing some of the symptoms of advanced, levodopa-responsive Parkinson's disease that are not adequately controlled with medication.

It is the first study in Parkinson patients outside the US with a Deep Brain Stimulation system using constant current instead of constant voltage and using a lead with an active electrode tip.

Full description

This study is designed as a prospective, observational, non-randomized, multi-centered study for 12 months in duration from implantation with the subjects being used as their own control. The primary outcome assessment will occur at three months: however, subjects will be followed for one year.

A comparison of measures within the same person from pre-treatment to post-treatment will be performed. Also, pre-treatment and post-treatment group means and standard deviations will be determined.
