摘要

The purpose of this study was to investigate and compare dynamic standing stability on the NeuroCom(superscript ®) Balance Master(superscript ®) system in normal subjects and Parkinsonian (PD) patients. Thirteen PD patients, aged 43 to 77 years, and 13 age-matched normals participated in the study. Seven patients were classified as mild and six as moderate disability sub-group by Hoehn and Yahr staging and a modified Webster's rating scale. The dynamic stability was quantitatively assessed on the Balance Master(superscript ®) for all subjects. The assessments include (1) amplitude and time for each excursion during lateral and front-back rhythmic weight shift tests and (2) movement time, accuracy and body sway while tracking from central to eight peripheral targets during limits of stability test on a computer screen. The results of paired t tests showed that the movement time taken from central to front, right-front, left-back, and left-front target was significantly longer in PD group than normal group (p＜.05). The results of independent t tests showed that the movement time taken to back target for patients with moderate disability was significantly longer than mild disability (P＜.05). The results of one way ANOVAs revealed that the movement time taken from central to right target for patients with moderate disability was significantly longer than mild disability and normals (p＜.05) and to left-front target for patients with moderate disability was significantly longer than normals (p＜.05). There were no significant differences between groups or among subgroups and normals in other dynamic variables. The results indicate that the movemnt time may be a precise parameter to distinguish between PD patients and normal subjects assessed on Balance Master(superscript ®) system.
