“…Beecroft et al (2008) report low correlations (TST 0.05-0.14; SE% 0.04-0.18; WASO )0.12 to 0.02) accuracy (51-61%) and sensitivity (43-44%) of ACTG and a relatively high specificity (75-95%) in ICU patients. Low correlations of ACTG with PSG were also found (SOL 0.17; TST 0.29; SE% 0.19) in sleepdisordered people with motor disability (Laakso et al, 2004). In wheelchair-bound demented elderly patients (Ancoli-Israel et al, 1997), however, higher correlations were found (TST 0.81-0.91; SE% 0.61-0.67; TWT 0.75-0.78), as well as in sleepdisordered patients (SOL 0.30-0.73; TST 0.70-0.82; WASO 0.48; SE% 0.43-0.91) (Laakso et al, 2004;Lichstein et al, 2006).…”

“…The results of the included studies show that the accuracy of ACTG compared with reference standard PSG, depends on (i) the population, (ii) the specific sleep variable of interest, (iii) algorithm and threshold used and (iv) make of actigraphic device. Included studies regarding healthy subjects (De Souza et al, 2003;Jean-Louis et al, 2001a,b;Laakso et al, 2004;Paquet et al, 2007;Pollak et al, 2001) report an overall agreement rate of 72.1-96.5% between ACTG and PSG, a sensitivity range of 86.5-98.7% and a specificity range of 27.7-67.1%. Most of these studies describe PearsonÕs correlation coefficients for at least one of the sleep variables: SOL (0.64-0.82), TST (0.43-0.97), WASO (0.36-0.39) and SE% (0.39-0.91).…”

SUMMAR Y Sleep disturbance influences human health. To examine sleep patterns, it is advisable to utilize valid subjective and objective measures. Laboratory-based polysomnography (PSG) is deemed the gold standard to measure sleep objectively, but is impractical for long-term and home utilization (e.g. resource-demanding, difficult to use). Hence, alternative devices have been developed. This study aimed to review the literature systematically, providing an overview of available objective sleep measures in nonlaboratory settings as an alternative to PSG. To identify relevant articles, a specific search strategy was run in EMBASE, PubMed, CINAHL, PsycInfo and Compendex (Engineering Village 2). In addition, reference lists of retrieved articles were screened and experts within this research field were contacted. Two researchers, using specified in ⁄ exclusion criteria, screened identified citations independently in three stages: on title, abstract and full text. Data from included articles were extracted and inserted into summarizing tables outlining the results. Of the 2217 electronically identified citations, 35 studies met the inclusion criteria. Additional searches revealed eight papers. Psychometric characteristics of nine different objective measures of sleep pattern alternatives to PSG [(bed) actigraphy, observation, bed sensors, eyelid movement-and non-invasive arm sensors, a sleep switch and a remote device] were evaluated. Actigraphy is used widely and has been validated in several populations. Alternative devices to measure sleep patterns are becoming available, but most remain at prototype stage and are validated insufficiently. Future research should concentrate on the development and further validation of non-invasive, inexpensive and user-friendly sleep measures for non-laboratory settings.

“…However, the agreement between these 2 methods weakened in patients with TBI, with sleep diary data of patients with TBI underestimating wake after sleep onset (WASO) and overestimating sleep onset latency (SOL). In patients with motor impairment, actigraphy tends to overestimate total sleep time [59]. Finally, studies to date have employed small sample sizes, primarily assessing mTBI, with limited data in moderate-to-severe TBI.…”

Sleep, Sleep Disorders, and Mild Traumatic Brain Injury. What We Know and What We Need to Know: Findings from a National Working Group

Disturbed sleep is one of the most common complaints following traumatic brain injury (TBI) and worsens morbidity and long-term sequelae. Further, sleep and TBI share neurophysiologic underpinnings with direct relevance to recovery from TBI. As such, disturbed sleep and clinical sleep disorders represent modifiable treatment targets to improve outcomes in TBI. This paper presents key findings from a national working group on sleep and TBI, with a specific focus on the testing and development of sleep-related therapeutic interventions for mild TBI (mTBI). First, mTBI and sleep physiology are briefly reviewed. Next, essential empirical and clinical questions and knowledge gaps are addressed. Finally, actionable recommendations are offered to guide active and efficient collaboration between academic, industry, and governmental stakeholders.
