"The aim of this study was to assess the correlation between substantia nigra (SN) echogenic features and area and the clinical symptoms in patients with Parkinson disease (PD). Methods. Clinical examinations and transcranial sonographic evaluations of the SN were performed in 115 consecutive patients with PD. The presence of tremors, rigidity, bradykinesia, gait disorders, speech disorders, and hypomimia was evaluated according to the motor portion of the Unified Parkinson Disease Rating Scale. The Mann-Whitney U test, the Kruskal-Wallis test, analysis of variance, and multivariate analysis were applied when assessing statistical significance. Results. An enlarged and hyperechoic SN existed in 84.0% of patients with bilateral rigidity... etc."@en . . "17110" . "6"^^ .
