The postural stability of four adult populations was examined through force platform methods. The four groups were classified as: (1) developmentally disabled (severely and profoundly mentally retarded) with tardive dyskinesia; (2) developmentally disabled but with no history of neuroleptic medication; (3) tardive dyskinetic but of normal intelligence; and (4) a normal and healthy control group. Postural conditions included standing still with arms at side, standing still with one arm or both arms parallel to the ground, and standing still while swinging both arms in the sagittal plane. The findings showed that both tardive dyskinetic and/or developmentally disabled groups exhibited greater sway and variability in centre of pressure motion in contrast to the control group. The developmentally disabled with tardive dyskinesia group also exhibited a strong tendency to produce a different form to the postural sway strategy in that they produced rhythmical centre of pressure motions during stance that were, to some degree, task dependent. The findings show that the combined effects of developmental disability and tardive dyskinesia produce qualitatively and quantitatively different features in postural stability patterns. The data suggest that postural stability measures may be a useful index to assess tardive dyskinesia.
通过测力平台方法对四组成年人群的姿势稳定性进行了检查。这四组被分类为：（1）患有迟发性运动障碍的发育障碍者（重度和极重度智力迟钝）；（2）发育障碍但无抗精神病药物治疗史者；（3）迟发性运动障碍但智力正常者；以及（4）正常健康对照组。姿势条件包括双臂垂于身体两侧静止站立、单臂或双臂平行于地面静止站立，以及在矢状面内摆动双臂时静止站立。研究结果表明，与对照组相比，迟发性运动障碍组和/或发育障碍组在压力中心运动方面表现出更大的摇摆和变异性。患有迟发性运动障碍的发育障碍组在姿势摇摆策略上也表现出一种强烈的倾向，即产生不同的形式，因为他们在站立期间产生了有节奏的压力中心运动，在某种程度上与任务相关。研究结果表明，发育障碍和迟发性运动障碍的综合影响在姿势稳定性模式上产生了质和量上不同的特征。数据表明，姿势稳定性测量可能是评估迟发性运动障碍的一个有用指标。
