AN ACTIGRAPHY BASED HEALTH EVALUATION METHOD FOR PATIENTS AND A DEVICE THEREFOR

摘要

A device and method for determining whether the symptoms of depression are improved by using three-dimensional acceleration measured in an exercise amount measuring instrument (100). Specifically, the device calculates a signal vector magnitude (SVM), calculates A5, which is the sum for five seconds by using the same, calculates the number of vibrations of the A5 by using the same, and determines the improvement degree of depression, which is proportional to a change in the number of vibrations of the A5.
