We measured motor activity with a self-contained monitoring device worn on the wrists of affectively ill patients and volunteer normal control subjects. Decreases in the daytime motor activity level were observed in depressed patients, compared with their improved (euthymic) or manic mood states. Moreover, affectively ill patients, even during euthymic periods, showed lower daytime motor activity levels than the control group housed in the same ward. These data provide objective evidence for decreases in motor activity that occur concomitantly with the depressive phase of illness in patients with affective disorder, and fluctuate in patients in euthymic or manic phases.
我们使用一种佩戴在情感障碍患者和正常志愿者手腕上的独立监测设备来测量运动活动。与病情改善（心境正常）或躁狂状态相比，抑郁症患者白天的运动活动水平有所下降。此外，情感障碍患者即使在心境正常期间，其白天的运动活动水平也低于同一病房的对照组。这些数据为情感障碍患者在疾病抑郁期伴随出现的运动活动减少提供了客观证据，并且在心境正常或躁狂期患者中会有所波动。
