CamNtech (MotionWatch 8, MotionWatch Rugged, PRO-Diary)

Abstract

Each the MotionWatch and the PRO-Diary are FDA cleared (1/21/2014) wrist-worn actigraphy gadgets supposed to observe limb or physique actions throughout day by day dwelling and sleep. They supply uncooked accelerometer information to be used in scientific or analysis settings. The MotionWatch 8 contains an ambient mild sensor and occasion marker, that are absent within the MotionWatch Rugged. The PRO-Diary alerts customers to reply survey questions on the system’s OLED display, with 2 buttons and a contact delicate ‘slider’ for information assortment. The Actiheart is a chest-worn accelerometry system which attaches with commonplace ECG electrodes. Accompanying software program can be found for system administration and information evaluation as wanted.

Claimed Capabilities/Measurements

CamNtech presents a number of merchandise: MotionWatch 8, MotionWatch Rugged, PRO-Diary, Actiheart 5, (Nano for animanls), and a Cloud Knowledge Supervisor. MotionWatch 8 is a water-resistant, medical-grade actigraphy system that makes use of a replaceable (3 month) battery. MotionWatch Rugged has a sturdy metal casing that can be utilized in harsh environments (akin to outdoor or army makes use of). Knowledge could be exported or analyzed utilizing included software program. The wrist-worn PRO-Diary gives actigraphy and customers can reply survey questions for ecological momentary assessments (EMA), with as much as 4 weeks of battery life. The light-weight Actiheart 5 provides actigraphy to a single lead ECG waveform sensor for as much as 14 days of information assortment.

Mechanism

Movement, ambient mild publicity (MotionWatch 8), coronary heart fee (Actiheart 5)

Sensors

Tri-axial accelerometer, mild sensor (MotionWatch 8 solely), single lead ECG waveform (Actiheart 5 solely)

Technical Issues

Throughout visits, (MotionWatch) system information are uploaded by employees to a safe server and the system is re-set for the affected person to proceed their recording.

Comparability Check(s): EMFIT QS

Research Abstract: This research in contrast a contactless mattress sensor utilizing ballistocardiography (EMFIT QS) with wrist actigraphy (MotionWatch 8 or Actiwatch 2) to observe sleep–wake patterns for 14 nights in 13 adults with reasonable to profound mental disabilities dwelling in a care setting. When evaluating the EMFIT to the Actiwatch, sensitivity was 76% and specificity and accuracy have been 75%. When evaluating the EMFIT to the MotionWatch, sensitivity, specificity and accuracy have been 66%. The authors concluded that the contactless mattress sensor was not correct in comparison with actigraphy and care-giver diary on this affected person inhabitants.

Comparability Check(s): N/A

Research Abstract: This secondary evaluation described bodily exercise utilizing the MotionWatch 8 amongst older adults (N=204, age 65 or older) dwelling with dementia on medical models in throughout 10 acute care settings. On this research, the primary 24hrs of actigraphy information was used for bodily exercise evaluations. Foremost findings have been that disinhibition and agitation/aggression, severity of delirium, being on a psychotropic treatment, variety of strolling actions, and toileting have been positively related to bodily exercise measured by the MotionWatch 8 and negatively related to sedentary exercise. The authors concluded that older hospitalized adults with dementia interact in low ranges of bodily exercise and that disinhibition and agitation/aggression, severity of delirium, being on a psychotropic treatment, variety of strolling actions, and toileting have been positively related to bodily exercise when measured by the MotionWatch 8 (which means that sufferers transfer extra when experiencing these signs) and negatively related to sedentary exercise.

Comparability Check(s): Self-reported bodily perform

Research Abstract: This research evaluated the feasibility and validity of the MotionWatch8 (MW8) in N=321 sufferers 65 yr or older with dementia who have been inpatient throughout 3 hospitals. Exercise cutpoints (sedentary ≤178 counts per minute, mild ≥179–561 counts per minute, reasonable ≥562 counts per minute, and vigorous ≥1,020 counts per minute) and have been examined for relationship with bodily perform (measured utilizing the Barthel Index). The authors concluded that sporting the MotionWatch was possible on this setting and for this inhabitants as most members have been prepared to put on the watch and wore it for the research length (24 hours). The authors additionally concluded that the MotionWatch had preliminary validity on this setting and inhabitants as regression evaluation demonstrated that the MotionWatch measured exercise was related to bodily perform. Time in low exercise (β =.17, p =.004), and time in reasonable exercise (β =.14, p=.017). The research gives preliminary help for the feasibility and validity of the MW8 in hospitalized individuals with dementia.

Comparability Check(s): PSQI

Research Abstract: This research evaluated sleep high quality for N=78 adults 55 and older. The goal was to find out the PSQI’s predictive validity for goal sleep high quality (utilizing MotionWatch 8). Outcomes reveal a major distinction between perceived and goal sleep high quality, with subjective measures (PSQI) typically not correlating properly with actigraphy. The authors conclude that each subjective and goal strategies ought to be used collectively for a extra correct evaluation of sleep high quality in older adults.

Comparability Check(s): Behavioral Threat Issue Surveillance System

Research Abstract: This research assessed the validity of the Behavioral Threat Issue Surveillance System (BRFSS) sleep questions by establishing the sensitivity and specificity for detection of sleep/ wake disturbance. The PRO-Diary was used to gather actigraphy for 14 days and acquire survey daya associated to sleep parameters. N=300 community-dwelling adults have been enrolled. The authors discovered that solely two out of 5 BRFSS sleep questions have been dependable and legitimate for measuring whole sleep time and extreme daytime sleepiness. The research recommends refining the BRFSS sleep questions to enhance sensitivity and specificity for detecting sleep disturbances.
