在最近的AASM实践中，当多导睡眠图不可用时，参数活动计法被引用来测量阻塞性睡眠呼吸暂停患者的总睡眠时间。因此，在28名已知睡眠呼吸障碍的受试者中，活动记录仪与多导睡眠图数据进行了比较。以金标多导睡眠图为标准，比较总睡眠时间(TST)、睡眠周期时间(SPT)、睡眠效率(SE)、持续睡眠效率(SSE)、入睡潜伏期(SL)和睡眠/觉醒模式。从活动图到多导睡眠图逐个时期比较睡眠/觉醒的结果，敏感度为90.2%，特异度为95.2%，总准确度为85.9%。上证综指(0.65，p<；0.001)和上证综指(0.65，p<；0.001)与上证综指(0.71，p<；0.001)的相关性中等，而科技股(0.89，p<；0.001)、特殊目的股(0.91，p<；0.001)和上证综指(0.89，p<；0.001)的相关性较高。结论：在无其他睡眠障碍的睡眠呼吸暂停患者中，肌动描记与PSG记录不一致，但对睡眠/觉醒模式和预测TST、SPT、SSE、SE和SL也有很好的效果。难以检测到正确的睡眠开始，导致SSE和SL的可预测性较差。因此，引入了15个时代的标准，导致睡眠潜伏期的高度相关性为0.89，但必须在更大的人群中进行测试。
In recent AASM practice, parameter actimetry is cited to measure total sleep time in obstructive sleep apnoea patients, when polysomnography is not available. An actigraph was therefore compared to polysomnographic data in 28 subjects with known sleep disordered breathing. Total sleep time (TST), sleep period time (SPT), sleep efficiency (SE), sustained sleep efficiency (SSE), sleep onset latency (SL) and sleep/wake pattern were compared to gold standard polysomnography. The results of an epoch-by-epoch comparison of sleep/wake from actigraphy to sleep stages from polysomnography gave a sensitivity of 90.2%, a specificity of 95.2% and an overall accuracy of 85.9%. Correlations were moderately strong for SE (0.71, p < 0.001) and SSE (0.65, p < 0.001) and high for TST (0.89, p < 0.001), SPT (0.91, p < 0.001) and SL (0.89, p < 0.001). It was concluded that actigraphy is not identical with PSG recording but gives good results in sleep/wake patterns and predicting TST, SPT, SSE, SE and SL also in sleep apnoea patients not suffering from other sleep disorders. The difficult detection of correct sleep onset causes SSE and SL to be less predictable. Therefore a 15-epoch criterion was introduced and resulted in high correlation of 0.89 for sleep latency, but has to be tested on a bigger population.
