The ActiGraph CentrePoint Insight Watch is a compact, battery-operated wearable activity recording device with physical characteristics similar to those of a small wristwatch. The watch is intended to acquire and store data from an onboard accelerometer while being worn during normal activities and/or during sleep. The data record is timestamped and stored in non-volatile memory for later retrieval. Downloaded data can be post-processed based on the timestamp and magnitude of acceleration along each axis. The housing is constructed of a combination of opaque and clear copolyesters formulated specifically for medical devices (i.e., tested and determined biocompatible), and the core data collection sensor is a 3-axis microelectromechanical system (MEMS) accelerometer. A charging dock connected to a USB power source is used to charge the device battery and communicate with a PC or peripheral.
A battery-powered device designed to continuously measure and record a patient's kinetic activity during routine ambulation, including monitoring the motion of individual joints/limbs, typically to assess joint mobility, gait performance, and fall-risk or frailty (e.g., during post-surgery rehabilitation). It consists of a motion sensor(s) worn on the torso or a limb (e.g., thigh, calf, wrist, ankle) while performing normal daily activities, and a computing device/software to which body movement signals are transmitted for recording/analysis; it may also be attached to or integrated in an external limb prosthesis for activity monitoring.
