Eye movement desensitization and reprocessing (EMDR) is a psychotherapy for the treatment of posttraumatic stress disorder (PTSD). It is still unclear whether symptoms remission through EMDR therapy is associated with a beneficial effect on one of the PTSD symptoms, sleep disturbance. Our objective was therefore to study sleep parameters before and after symptom remission in soldiers with PTSD. The control group consisted of 20 healthy active duty military men who slept in a sleep lab with standard polysomnography (PSG) on two sessions separated by one month. The patient group consisted of 17 active duty military with PTSD who underwent EMDR therapy. PSG-recorded sleep was assessed 1 week before the EMDR therapy began and 1 week after PTSD remission. We found that the increased REMs density after remission was positively correlated with a greater decrease of symptoms. Also, the number of EMDR sessions required to reach remission was correlated with intra-sleep awakenings before treatment. These results confirm the improvement of some sleep parameters in PTSD after symptoms remission in a soldier's population and provide a possible predictor of treatment success. Further experiments will be required to establish whether this effect is specific to the EMDR therapy.
眼动脱敏再处理（EMDR）是一种治疗创伤后应激障碍（PTSD）的心理治疗方法。目前尚不清楚通过 EMDR 治疗缓解症状是否与 PTSD 的一种症状，即睡眠障碍的有益影响有关。因此，我们的目的是研究 PTSD 士兵在症状缓解前后的睡眠参数。对照组由 20 名健康现役军人组成，他们在睡眠实验室中进行了两次标准多导睡眠图（PSG）记录，两次记录之间间隔一个月。患者组由 17 名接受 EMDR 治疗的现役 PTSD 士兵组成。PSG 记录的睡眠在 EMDR 治疗开始前 1 周和 PTSD 缓解后 1 周进行评估。我们发现，缓解后 REM 密度的增加与症状的更大减轻呈正相关。此外，达到缓解所需的 EMDR 治疗次数与治疗前的睡眠内觉醒次数有关。这些结果证实了 PTSD 患者在症状缓解后一些睡眠参数的改善，并提供了治疗成功的可能预测指标。需要进一步的实验来确定这种效果是否特定于 EMDR 治疗。
