<P>PROBLEM TO BE SOLVED: To provide an apparatus for detecting periodic body motion. <P>SOLUTION: The apparatus 10 is provided which analyzes load fluctuation data 12 acquired from a plurality of pressure sensors 7 arranged under a subject 9 to detect changes of load distribution of the subject 9. The analysis apparatus 10 includes a first unit 31 that acquires first values corresponding to the change amounts of the absolute values of an alternative components of the respective load fluctuation data 12 of the plurality of pressure sensors 7 and acquires a body motion amount (first data) 13 that includes components obtained by regularly summing up the first values of the plurality of pressure sensors 7 at first time interval, and a second unit 32 that determines presence or absence of periodic body motion or periodic limb movement of the subject 9 on the basis of the body motion amounts 13. <P>COPYRIGHT: (C)2011,JPO&INPIT |
