The RSGE-PD-V2.0 is a specific measure for evaluation of gait impairment in PD.
To check the RSGE-PD-V2.0 metrics attributes.
In addition to demographic and historical data of PD, applied assessments were: Hoehn and Yahr staging (H&Y); impact in daily activities with Schwab and England scale (S&E); SCOPA Motor; mental status with Short portable mental status questionnaire (SPMSQ); quality of life with Parkinson's impact scale (PIMS), the Hamilton Depression Rating Scale-6 items (HDRS-6); and, the Clinical Impression of Severity Index-PD (CISI-PD).
151 PD patients were included (n = 102 (67.5%) were male). Most patients were in H&Y stage 3 (n = 78 (51.6%)). Mean of age and duration of disease was 68.4 and 7.6 years respectively. Mean values of L-Dopa doses was 652.6 mg/day. Mean values of SCOPA Motor were 29.1; SPMSQ: 1.8; HADS-6: 9.2; PIMS: 18.7;RSGE-PD-V2.0: 25.4; and, CISI-PD were 10.8. Full computable scores were 100%; Guttman's lambda, 0.954; and the item-total correlation, 0.408-0.830. Correlation coefficients (Spearman's rho) between RSGE-PD-V2.0 and H&Y, S&E, SCOPA Motor, PIMS and CISI-PD, were: 0.62; -0.75; 0.74; 0.46; and, 0.78 respectively. RSGE-PD-V2.0 scale significantly discriminated among PD severity levels (based on H&Y staging) Kruskal-Wallis (p < 0.000).
Metric attributes of the RSGE-PD-V2.0 in this sample of study resulted in has sufficient and suitable satisfactory. We, therefore, believe that RSGE-PD-V2.0 is easy and a useful and recommendable specific tool for measuring gait disease in PD patients. © 2010 Movement Disorder Society
