This study explored the efficacy of 1 actigraphy (ACT) brand, at different analytic settings, for use to administer the Multiple Sleep Latency Test (MSLT). Forty-one first-time postpartum mother and father participants were administered the MSLT with concurrent ACT. To identify ACT sleep onset latency (SOL), ACT signals were interpreted with iterations of different "wake threshold value" (WTV) and "immobile minutes for sleep onset" value (IMV) settings. The different iterations of ACT-SOL values were compared to MSLT-SOL values. The WTV settings did not affect ACT-SOL, but the ACT-SOL and MSLT-SOL significantly differed at each ACT-IMV setting. ACT consistently identified SOL too soon; however, future research, along with technological innovation, may identify a viable methodology to conduct an ambulatory MSLT.
这项研究探索了 1 种活动记录仪（ACT）品牌在不同分析设置下用于进行多次睡眠潜伏期试验（MSLT）的功效。41 名初次产后母亲和父亲参与者接受了 MSLT 和同时进行的 ACT。为了确定 ACT 的睡眠起始潜伏期（SOL），通过不同的“唤醒阈值值”（WTV）和“睡眠起始无活动分钟”值（IMV）设置迭代来解释 ACT 信号。将不同迭代的 ACT-SOL 值与 MSLT-SOL 值进行比较。WTV 设置不影响 ACT-SOL，但在每个 ACT-IMV 设置下，ACT-SOL 和 MSLT-SOL 差异显著。ACT 总是过早地确定 SOL；然而，随着技术创新，未来的研究可能会确定一种可行的方法来进行非卧床 MSLT。
