Background. Freezing of Gait (FOG) is a disabling parkinsonian symptom. The Freezing of Gait Questionnaire (FOG-Q) reliably detects FOG in patients with Parkinson's disease (PD). Objectives. The aim of this study was to develop a German translated version of the FOG-Q and to assess its validity. Methods. The translation was accomplished using forward-backward-translation. The construct validity...

BACKGROUND Parkinson's disease (PD) patients are affected by hypokinetic dysarthria, characterized by hypophonia and dysprosody, which worsens with disease progression. Levodopa's (l-dopa) effect on quality of speech is inconclusive; no data are currently available for late-stage PD (LSPD). OBJECTIVE To assess the modifications of speech and voice in LSPD following an acute l-dopa challenge. ...

We evaluated motor function in 41 consecutive PD patients undergoing unilateral MRI/microelectrode-guided posteroventral pallidotomy to determine whether the motor effects of levodopa therapy change after surgery. Total Unified Parkinson's Disease Rating Scale motor "off" and motor "on" subscores all improved and the rapidity of action, magnitude, and duration of motor response to levodopa ther...

In recent years, a few of randomized controlled trials (RCTs) about amantadine for treating dyskinesia in Parkinson's disease (PD) were completed. Here, we conducted a systematic literature review about the clinical research to provide the updated evidence for treating dyskinesia. Electronic search of Medline, PubMed, Cochrane Library, and other databases up to May 2016 for relevant studies was...

OBJECTIVES To test a hypothesis that patients with Parkinson's disease may not notice discrepancies between their perceived and actual stability limits and cannot keep their centre of gravity within the stability region. SETTINGS Outpatients with neurological disorders in rehabilitation service. SUBJECTS Twenty-one patients with Parkinson's disease (11 men, 10 women; mean duration 5.9 +/- 3...

BACKGROUND AND PURPOSE The possibility of using MR imaging as a sensitive marker of the structural changes in Parkinson's disease has been a long-sought goal. We describe a new method for imaging and quantifying the morphologic changes of the substantia nigra in Parkinson's disease and compare radiologic findings with clinical evaluation. METHODS Using a combination of two MR imaging inversio...

We performed an analysis of prospectively-acquired cross sectional data on 106 Parkinson disease (PD) patients who underwent comprehensive neuropsychological testing and the Unified Parkinson Disease Rating Scale (UPDRS) motor scale. A significant correlation between the UPDRS motor and neuropsychological tests in all cognitive domains except for general intelligence and visuo-spatial function ...
