Wrist actigraphy predicts outcome in patients with pulmonary hypertension.
BACKGROUND Pulmonary hypertension (PH) impairs quality of life, exercise performance and survival. Simple measures to monitor the disease are needed. OBJECTIVES We tested whether actigraphy by a wrist-worn device in the patient's home reflects disease severity in PH patients. METHODS Twenty-three outpatients with pulmonary arterial and chronic thromboembolic PH (15 females), functional clas...
متن کاملWhat wrist should you wear your actigraphy device on? Analysis of dominant vs. non-dominant wrist actigraphy for measuring sleep in healthy adults
OBJECTIVE Differences in sleep results due to the placement of actigraphy devices (non-dominant vs. dominant wrist) are yet to be determined. METHODS 65 nights of data from 13 adult participants was collected while participants wore two actigraphy devices, one on each wrist. Sleep indices including total sleep time (TST), total time in bed (TTB), sleep efficiency (SE%), sleep latency (SL), wa...
متن کاملA novel adaptive wrist actigraphy algorithm for sleep-wake assessment in sleep apnea patients.
STUDY OBJECTIVES Current actigraphic algorithms are relatively less accurate in detecting sleep and wake in sleep apnea patients than in people without sleep apnea. In the current study, we attempted to validate a novel automatic algorithm, which was developed for actigraphic studies in normal subjects and patients with obstructive sleep apnea by comparing it on an epoch-by-epoch basis to stand...
متن کاملAlternatives to polysomnography (PSG): a validation of wrist actigraphy and a partial-PSG system.
The objective of this study was to assess the validity of a sleep/wake activity monitor, an energy expenditure activity monitor, and a partial-polysomnography system at measuring sleep and wake under identical conditions. Secondary aims were to evaluate the sleep/wake thresholds for each activity monitor and to compare the three devices. To achieve these aims, two nights of sleep were recorded ...
متن کاملA validation of wrist actigraphy against polysomnography in patients with schizophrenia or bipolar disorder
PURPOSE Sleep disturbances are frequent in patients with schizophrenia or bipolar disorder. Actigraphy has been established as a generally reliable method to examine these disturbances across varying time spans, but the validity against polysomnography (PSG) is not well investigated for this population. We validated wrist-worn actigraphy against PSG in a population of chronic, medicated patient...
