Actigraphy and Accelerometry
Actigraphy testing consists of a small portable device (actigraph) that senses physical motion and stores the resulting information. Actigraphy testing has been predominantly used in research studies to evaluate rest-activity cycles in patients with sleep disorders, to determine circadian rhythm activity cycles, and to determine the effect of a treatment on sleep. The actigraph is most commonly...
متن کاملEvaluation of an open source method for calculating physical activity in dogs from harness and collar based sensors
BACKGROUND The ability to make objective measurements of physical activity in dogs has both clinical and research applications. Accelerometers offer a non-intrusive and convenient solution. Of the commercialy available sensors, measurements are commonly given in manufacturer bespoke units and calculated with closed source approaches. Furthermore, the validation studies that exist for such devic...
متن کاملLess structured movement patterns predict severity of positive syndrome, excitement, and disorganization.
Disorganized behavior is a key symptom of schizophrenia. The objective assessment of disorganized behavior is particularly challenging. Actigraphy has enabled the objective assessment of motor behavior in various settings. Reduced motor activity was associated with negative syndrome scores, but simple motor activity analyses were not informative on other symptom dimensions. The analysis of move...
متن کاملPractice parameters for the use of actigraphy in the assessment of sleep and sleep disorders: an update for 2007.
BACKGROUND Actigraphy is increasingly used in sleep research and the clinical care of patients with sleep and circadian rhythm abnormalities. The following practice parameters update the previous practice parameters published in 2003 for the use of actigraphy in the study of sleep and circadian rhythms. METHODS Based upon a systematic grading of evidence, members of the Standards of Practice ...
متن کاملUse of Actigraphy in Neurological Patient Populations
An actigraph is a portable device that measures movement, usually of the non-dominant wrist, to estimate rest-activity patterns and sleepwake cycles. The use of actigraphy has grown over the past decade. Actigraphy has gained favor in the sleep community for the evaluation of insomnia and circadian rhythm disorders, and the device has become an important research tool. As sleep disorders are co...
