Polysomnography (PSG) is a standard procedure for investigating sleep functions including behavior. This technique is described. The diagnostic value of PSG is shown by statistical data from the literature and our own patient sample which includes 442 insomniacs. In one out of five patients, insomnia is related to a known somatic factor, i.e. periodic movements in sleep or sleep apnea, which can only be reliably identified by PSG. A more differentiated analysis shows that PSG yields important diagnostic information in 50 to 75% of insomniacs. Three cases are reported, showing that even patients without clinical indications for sleep disturbance can have deficient sleep functions. If they can be specifically addressed, this may be the turning point of the treatment. Therefore, a wide application of PSG is favored.
多导睡眠图（PSG）是一种用于研究包括行为在内的睡眠功能的标准程序。本文描述了该技术。文献中的统计数据以及我们自己包含442名失眠症患者的样本显示了PSG的诊断价值。五分之一的患者中，失眠与已知的躯体因素有关，即睡眠中的周期性运动或睡眠呼吸暂停，而这只能通过PSG可靠地识别。更细致的分析表明，PSG在50%至75%的失眠症患者中产生重要的诊断信息。报告了三例病例，表明即使没有睡眠障碍临床指征的患者也可能存在睡眠功能缺陷。如果能够针对性地解决这些问题，这可能是治疗的转折点。因此，倾向于广泛应用PSG。
