To examine concordance of accelerometer-based actigraphy (ACG) with polysomnography (PSG) in the determination of sleep states in inpatients with traumatic brain injury (TBI), and examine the impact of injury severity and comorbid conditions (spasticity, apnea) on concordance.
This was a convenience sample of 50 participants with primarily severe TBI.
This was a retrospective chart review of concurrent administration of PSG with ACG in nonconsecutive rehabilitation admissions with TBI.
Total sleep time and sleep efficiency were measured by PSG and ACG.
Moderate to strong correlations between ACG and PSG were observed for total sleep time (r = 0.78, P < .01) and sleep efficiency (r = 0.66, P < .01). PSG and ACG estimates of total sleep time (316 minutes vs 325 minutes, respectively) and sleep efficiency (78% vs 77%, respectively) were statistically indistinguishable.
Actigraphy is a valid proxy for monitoring of sleep in this population across injury severity and common comorbidity groups. However, further research with larger sample sizes to examine concordance in patients with TBI with disorder of consciousness and spasticity is recommended.
研究基于加速度计的活动记录仪（ACG）与多导睡眠图（PSG）在判定创伤性脑损伤（TBI）住院患者睡眠状态方面的一致性，并研究损伤严重程度和合并症（痉挛、呼吸暂停）对一致性的影响。
这是一个由50名主要为重度TBI患者组成的便利样本。
这是一项对TBI非连续康复入院患者同时进行PSG和ACG检查的回顾性病历审查。
通过PSG和ACG测量总睡眠时间和睡眠效率。
观察到ACG与PSG在总睡眠时间（r = 0.78，P <.01）和睡眠效率（r = 0.66，P <.01）方面存在中度至高度相关性。PSG和ACG对总睡眠时间（分别为316分钟和325分钟）和睡眠效率（分别为78%和77%）的估计在统计学上无显著差异。
活动记录仪是监测该人群不同损伤严重程度和常见合并症组睡眠情况的有效替代方法。然而，建议进行更大样本量的进一步研究，以检查意识障碍和痉挛的TBI患者的一致性。
