摘要

PROBLEM TO BE SOLVED: To provide a posture change determination system, a method and a program for supporting a long-term bed rest to surely perform a posture exchange and managing the time when the posture exchange is performed. SOLUTION: A management device 100 of a body position change determination system 1 has a function of lying down from a signal receiving unit 151 for receiving a detection signal from a vibration sensor 230 included in the detection device 200 and a detection signal subjected to Fourier conversion. The body position exchange determination unit 152 that determines whether or not the person has performed the body position exchange and the body position exchange that stores the time of the detection signal that determines that the person has performed the body position exchange in the body position exchange time DB 141 It includes a time storage unit 153 and an alert output unit 154 that outputs an alert when a predetermined time has elapsed since the body position was changed.
