A 46-year-old patient with a lesion limited to the left retrorolandic area without involvement of the prerolandic motor strip was examined. Anaesthesia to tactile, warm, cold, and painful stimuli was complete for the right hand and wrist. Position sense was abolished for the right wrist and finger joints. Performance of the right hand in motor tasks was severely impaired. Simple visual and auditory reaction times were lengthened. Sustaining a constant level of force was impossible. In the absence of visual feedback, only simple, monoarticular movements could be correctly executed; more complex movements requiring coordination between several joints, such as prehension, were poorly, or not, performed. The role of somatosensory cortex in conveying kinaesthetic input to the motor areas and the importance of vision in substituting for kinaesthetic loss, are discussed.
对一名46岁患者进行了检查，其病灶局限于左侧罗兰后区，未累及运动前区运动带。右手和手腕对触觉、温觉、冷觉和痛觉刺激的感觉缺失。右手腕和手指关节的位置觉丧失。右手执行运动任务的能力严重受损。简单视觉和听觉反应时间延长。无法维持恒定的力量水平。在没有视觉反馈的情况下，只能正确执行简单的单关节运动；更复杂的需要多个关节协调的运动，如抓握动作，执行得很差或根本无法执行。本文讨论了体感皮层在向运动区传递动觉输入中的作用以及视觉在替代动觉丧失中的重要性。
