Methylphenidate for the Treatment of Gait Impairment in Parkinson's Disease

Summary

The purpose of this research study is to examine whether Methylphenidate (MPD) can result in improvement of gait (walking) in a population of Parkinson's Disease (PD) patients whose main disability is freezing of gait. MPD (Ritalin®) is a drug which can excite or stimulate certain systems of the body that control motor function. This drug is FDA approved for the treatment of attention hyperactivity disorder, a condition unrelated to PD. The researchers hypothesize that daily treatment with a tolerable daily oral dose of MPD will improve gait velocity, stride length, cadence, and decrease freezing of gait, 3 months from treatment initiation in patients with moderately advanced PD, whose gait impairment is an important source of disability despite optimized antiparkinsonian treatment.
