Abstract
The ActiGraph LEAP Multisensor Watch provides (PPG, microphone, gyroscope, barometer) sensors and knowledge outputs to the performance of its earlier model, Actigraph’s Centrepoint Perception Watch. LEAP is a prescription, wearable, activity-recording watch that gives high-resolution steady measures of bodily exercise, sleep, mobility, and important indicators together with coronary heart price and variability (HRV), oxygen saturation (SpO2), respiratory price, a-fib/cardiac rhythm, and pores and skin temperature. Motion dysfunction scores additionally can be found. Per 6/23/23 FDA clearance, it’s supposed to watch exercise related to motion throughout sleep and these knowledge can be utilized to research circadian rhythms and assess exercise in any occasion the place quantifiable evaluation of bodily movement is fascinating. There aren’t any publications for LEAP and its added knowledge outputs and performance (as of 9/6/24), however there are publications for prior Actigraph watch variations which seem to make use of the identical accelerometer knowledge assortment and processing for motion and sleep (see Centrepoint evaluate). In comparison with its predicate gadget (ActiGraph CentrePoint Perception Watch), its define dimensions differ for aesthetic functions, and biocompatibility testing has been submitted for its materials. Its sensor profile consists of extra sensors corresponding to multi-wavelength photoplethysmography (PPG), gyroscope, barometer, and microphone. At the moment, very younger kids or populations with very small wrists could also be a problem by way of usability.
Claimed Capabilities/Measurements
Along with Actigraph’s Centrepoint knowledge outputs, Actigraph’s LEAP has further (PPG, microphone, gyroscope, barometer) sensors that present further knowledge outputs and performance. This prescription multisensor gadget measures sleep (complete sleep time, sleep effectivity, wake after sleep onset, sleep onset latency, sleep fragmentation index, REM, non-REM sleep). Extra capabilities embody measuring bodily exercise (complete motion, average to vigorous bodily exercise, non-sedentary time step rely, vitality expenditure), gait and steadiness (gait pace/cadence, distance, spatiotemporal gait options, fall danger, posture detection), and important indicators (coronary heart price, coronary heart price variability, oxygen saturation, pores and skin temperature, A-Fib/cardiac rhythm, respiratory price). Very important indicators are generated from the CentrePoint platform. Automated distant knowledge uploads are through cell app or house knowledge hub.
Mechanism
Motion, coronary heart price, pores and skin temperature
Sensors
Triaxial MEMS accelerometer, Multi-Wavelength Photoplethysmography (PPG), gyroscope, pores and skin temperature sensor, barometer, microphone
Technical Issues
Occasion markers may be created by urgent and holding the button on the aspect of the gadget for 3 seconds. The information from the Bluetooth 5 and USB- enabled LEAP may be transferred through CentrePoint Join App or the CentrePoint Hub. ActiLife7.0 software program was lately up to date to assist uncooked accelerometer knowledge from the gadget with further sensor knowledge accessible by 2025. Moreover the wrist, LEAP’s put on places are deliberate to incorporate the higher arm, hip, lumbar, and ankle in 2024 (unspecified date). For VS measurements, sensor knowledge reportedly will probably be accessible in This fall 2024 or later.
