A case of hemianaesthesia caused by right hemisphere stroke was found to have good sensitivity and cutaneous localisation when she touched her impaired hand with her good contralateral hand or with a probe held by that hand. The capacity did not depend solely upon movement or positioning of her right arm, and she could also discriminate whether her own left fingers, as opposed to someone else's inter-digitated fingers, were being touched, but only when she did the touching. Thus, the threshold of the impaired hand appeared to be markedly affected by active involvement of the contralateral limb in delivering the stimulus.
一名因右半球中风导致偏身感觉缺失的患者，当她用对侧的好手触摸患手或用该手持握的探针触摸患手时，发现其具有良好的感觉灵敏度和皮肤定位能力。这种能力并非仅仅取决于右臂的运动或位置，她还能够辨别是自己的左手手指被触摸，而不是别人交叉的手指，但前提是由她自己进行触摸。因此，患手的阈值似乎明显受到对侧肢体在传递刺激时的积极参与的影响。
