体动记录仪在非器质性失眠症诊断中的作用

Investigation of actigraphy in diagnosis for non-organic insomnia

目的评价体动记录仪(Actigraphy)在非器质性失眠症诊断中的作用。方法选择非器质性失眠症患者34例,对照组20例。采用体动记录仪评价睡眠效果,同时,采用匹茨睡眠质量指数量表评定受试者最近1个月睡眠质量。结果非器质性失眠症患者与对照组相比,实际觉醒时间、睡眠潜伏期、平均每次觉醒时间显著延长(P<0.01),睡眠效率、平均静息状态时长显著降低(P<0.01),同时平均活动分数和割裂指数显著升高(P<0.05)。PSQI评定结果发现,非器质性失眠症患者PSQI均>7,达到16.88±4.56;对照组PSQI均<7,为4.53±1.69,二者相比差异有统计学意义(P<0.01)。结论非器质性失眠症的诊断方法中,体动记录仪可以成为一种有效辅助方法。

Objective To evaluate the effects of actigraphy in diagnosis for non-organic insomnia. Methods Actigraphy was employed to evaluate the sleep effects for 34 cases of non-organic insomnia and 20 controlling cases, while Pittsburgh Sleep Quality In- dex （PSQI） was used to assess sleep qualities for these subjects during the latest.month. Results In contrast to the controlling group, the non-organic insomnia group demonstrated significant prolongation of actual Sleep time（AST）, sleep latency （AS）, mean wake bout time （MWBT） （ P〈0.01） and decrease of sleep efficiency （SE） and mean length immobility （MLI） （ P〈0.01 ）, whilst mean activity score（MAS）and fragmentation index（FI） were obviously improved（P〈0.05）. All PSQI for the non-organic insomnia group were more than 7,reaching 16.88±4.56;but for the controlling group,the PSQI were not up to 7,only with the scores of 4.53± 1.69,which showed significant difference（P〈0. 01）. Conclusion Actigraphy is an effective accessory way for the diagnosis of non-organic insomnia.
