The influence of muscular tension upon visual vertical judgement in a standing posture was investigated in 16 hemiplegic persons and 12 normal elderly persons. The normal elderly group showed that their judgements of verticality were accurate and stable. In hemiplegic persons, judgements were displaced opposite to the side in which there was high tension in the body. Differences between groups in body tension and the side to which judgement was displaced were significant. The peculiar judgement errors made by hemiplegic persons are thus an overcorrection for tonicity. It was related to one's own body perception.
对16名偏瘫患者和12名正常老年人进行了研究，以探讨站立姿势下肌肉张力对视觉垂直判断的影响。正常老年组显示他们的垂直度判断准确且稳定。在偏瘫患者中，判断向身体张力高的一侧的相反方向偏移。两组在身体张力和判断偏移方向上的差异具有显著性。因此，偏瘫患者所产生的特殊判断误差是对张力的过度校正。这与自身身体感知有关。
