Abstract
A leg movement acquisition unitcontinuously acquires leg movements of a sleeping subject. An apnea detection unitdetects whether or not the subject is in a state of apnea. A movement analysis unitdetermines whether or not the detected leg movement satisfies previously determined conditions. These previously determined conditions include at least the following conditions (a) to (d): (a) The duration of leg movement is within a previously determined range; (b) intensity of leg movement is a previously determined value or greater; (c) leg movements satisfying conditions (a) and (b) continue for a previously determined number of times within a previously determined duration; and (d) the leg movement is not movement from immediately before to immediately after an apnea state that has been detected by the apnea detection unit. A coefficient calculation unitcalculates a coefficient based on the number of times of leg movement that satisfied the previously determined conditions. An output unitoutputs the coefficient or a determination result based on the coefficient.
