To examine intermanual differences in performing a clinical, visuoconstructional task. While many examiners have their hemiparetic patients complete visuospatial tasks with their nondominant hand, normative data have only been available based on dominant hand performance. This study sought to determine normal differences in intermanual visuoconstructional performance.
A group of individuals with no history of neurologic disorder completed a visuoconstruction task with their dominant and nondominant hands. Intermanual differences were compared.
General metropolitan community.
Forty-four individuals with no history of psychiatric, neurologic, visual, or motor impairment. Mean age was 29 years. Mean education level was 16 years.
Free-drawn clock drawings.
The intermanual difference was not significant (t(43) = 1.95, p = .06). Ninety-three percent scored within normal limits with their nondominant hand.
Use of the nondominant hand for clock drawing appears to be a reasonable alternative for those who are unable to use their dominant hand.
研究在执行一项临床视觉构建任务时双手之间的差异。虽然许多检查者让偏瘫患者用非优势手完成视觉空间任务，但规范数据仅基于优势手的表现。本研究旨在确定双手视觉构建表现的正常差异。
一组无神经系统疾病史的个体用优势手和非优势手完成一项视觉构建任务。比较双手之间的差异。
大都市普通社区。
44名无精神、神经、视觉或运动障碍史的个体。平均年龄29岁。平均教育水平为16年。
自由绘制时钟图。
双手差异不显著（t(43)=1.95，p = 0.06）。93%的人用非优势手得分在正常范围内。
对于无法使用优势手的人来说，用非优势手绘制时钟图似乎是一个合理的选择。
