To provide a motor function evaluation device and a motor function evaluation method capable of evaluating a motor function of a subject comprehensively and easily. A motor function evaluation deviceof the present invention includes a measurement base, a load measurement unitthat measures load change over time of the subject applied to the measurement base, and an arithmetic unitthat determines a balance ability indicator of the subject determined by the load change over time measured by the load measurement unit. The arithmetic unitdetermines the balance ability indicator from a time interval from when the subject stands up and the load applied to the load measurement unitis maximized until when the load variation is stabilized.

A balance ability measurement apparatus acquires load information on weight of a user as measured during a period of a stand-up movement which is a period of time from when the user starts the stand-up movement to when the user stabilizes standing posture. Based on the load information, the balance ability measurement apparatus calculates load change information on change in the weight of the user. Further, based on the load information, the balance ability measurement apparatus calculates left-right displacement information on displacement of the user in left-right direction. Based on the load change information and the left-right displacement information, the balance ability measurement apparatus calculates a balance ability evaluation value on balance ability of the user.

A digital scale is provided that switches a measuring interval according to the amount of variation of sampled data, and computes a weight. Embodiments include a scale with pre-stored scale intervals set at multiple levels, and allowable ranges of fluctuation that correspond to the scale intervals. The scale acquires digital data of a load continuously, and computes a predetermined number, or a fluctuation range in a predetermined time, of the acquired digital data. The scale then determines the degree of variation of the digital data by comparing the computed fluctuation range with the allowable range of fluctuation stored for each scale interval, and switches the scale interval based on the determined degree of variation, thereby allowing the scale to measure and compute the weight of the load even if the fluctuation is large.

An abdomen width determiner determines an abdomen width value of a human subject. A memory stores a correlation between abdomen width values and waist circumferences of human beings. A waist circumference calculator calculates a waist circumference of the human subject on the basis of the abdomen width value determined by the abdomen width determiner and the correlation stored in the memory. The correlation stored in the memory may be expressed by the following regression formula: Y=aX+b where 'Y' is a waist circumference of a human being, 'X' is an abdomen width value of a human being, and &#x201c;a&#x201d; and &#x201c;b&#x201d; are constants.

In this way, the addresses of defective memory in 16 word lines worth of a memory region are stored in the second memory array, therefore addresses of a wider range of defective memory can be stored. For this reason, it becomes possible to repair defects occurring at random efficiently.
