目的帕金森病（Parkinson's disease，PD）是一种以视觉空间和身体图式障碍为特征的疾病。患有PD的人经常表现出测量不足运动和图形测量不足（即，较小的图纸尺寸）。本研究的目的是通过评估骨盆和时钟绘制尺寸（即，高度和宽度），并通过调查骨盆绘图尺寸和参与者特征之间的关联。方法20例特发性PD患者（Hoehn &Yahr分期I-III），男16例，女4例，平均年龄65.75 ± 10.13岁。绘制骨盆和时钟绘制测试用于评估绘制尺寸，然后将其与PD严重程度、阶段和持续时间、认知水平、症状发作侧和骨盆图式评分相关。还使用了二元和多元线性回归分析。结果测量骨盆和时钟绘图尺寸显示出良好的（.844-.999）评分员间信度。骨盆绘图尺寸在大小上没有显著差异（P > 0.05），而时钟绘图高度显著（p <0.01）大于宽度，两者都表明图形测量困难（即，扭曲的图形尺寸）。骨盆牵引宽度与PD严重程度和分期呈负相关，与骨盆图式评分呈正相关，并预测所有三个参数。结论测量骨盆绘图尺寸，特别是骨盆绘图宽度，有可能作为PD评估的辅助诊断措施，并用于检测骨盆图式缺陷或误解。该测试可由物理治疗师在临床上用于评估PD患者的疾病严重程度，阶段和骨盆图式。从这项研究中获得的知识有助于更好地理解PD患者的图形度量表示和相关缺陷。未来的研究应该探讨骨盆绘图尺寸和骨盆心理成像估计之间的关系，以及它们在PD患者运动规划，控制和执行中的作用。
Objectives Parkinson's disease (PD) is characterized by visuospatial and body schema deficits. People with PD often exhibit hypometric movements and graphic hypometria (i.e., small drawing dimensions). The goal of the current study was to explore graphic-metric representation in people with PD by assessing pelvic and clock drawing dimensions (i.e., height and width) and by investigating associations between pelvic drawing dimensions and participant characteristics. Methods Twenty people (16 males, 4 females; M age: 65.75 +/- 10.13 years) with idiopathic PD (Hoehn &Yahr Stages I-III) volunteered to participate in this study. Draw Your Pelvis and Clock Drawing tests were used for assessing drawing dimensions, which were then correlated with PD severity, stage and duration, cognitive level, side of symptoms onset, and pelvic schema score. Bivariate and multiple linear regression analyses were also used. Results Excellent (.844-.999) interrater reliability was shown for measuring pelvic and clock drawing dimensions. Pelvic drawing dimensions did not significantly (P > .05) differ in magnitude, whereas clock drawing height was significantly (p < .01) greater than width, both suggesting graphic dysmetria (i.e., distorted graphic dimensions). Pelvic drawing width was negatively associated with PD severity and stage, was positively associated with pelvic schema score, and predicted all three parameters. Conclusion Measuring pelvic drawing dimensions, and specifically pelvic drawing width, holds potential as an adjunct diagnostic measure in PD assessments and for detecting pelvic schema deficits or misperceptions. This test can be used by physical therapists in the clinic for assessing disease severity, stage, and pelvic schema in people with PD. The knowledge gained from this study contributes to a greater understanding of graphic-metric representation and associated deficits in people with PD. Future studies should explore the relationship between pelvic drawing dimensions and pelvic mentally imaged estimates, and their role in motor planning, control, and execution in people with PD.
