The usefulness of motor subtypes of delirium is unclear due to inconsistency in sub-typing methods and a lack of validation with objective measures of activity. The activity of 40 patients was measured with 24 h accelerometry monitoring. Patients with Diagnostic and Statistical Manual of Mental Disorders, fourth edition (DSM-IV) delirium (n=30) were allocated into hyperactive, hypoactive and mixed motor subtypes. Delirium subtypes differed in relation to overall amount of activity, including movement in both sagittal and transverse planes. Differences were greater in the daytime and during the early evening 'sundowning' period. Frequency of postural changes was the most discriminating measure examined. Clinical subtypes of delirium defined by observed motor behaviour on the ward differ in electronically measured activity levels.
由于亚类划分方法不一致以及缺乏与活动的客观测量相验证，因此意识障碍的运动亚型的实用性尚不清楚。40 名患者的活动通过 24 小时加速计监测进行测量。患有《精神障碍诊断与统计手册》第四版（DSM-IV）意识障碍的患者（n=30）被分为高活动型、低活动型和混合运动型。意识障碍亚型在总活动量方面存在差异，包括矢状面和横断面上的运动。白天和傍晚“日落”时段差异更大。姿势变化的频率是检查的最具鉴别力的措施。根据病房中观察到的运动行为定义的意识障碍临床亚型在电子测量的活动水平上存在差异。
