A method and apparatus for testing the plausibility of electric impedance measurement values. The measurement values are determined during the measurement of the bioimpedance of a person. Real parts and imaginary parts of the impedance measurement values are determined for a plurality of different frequencies and are localized in a complex representation plane. The representation plane is defined by a coordinate axis for the imaginary part and a coordinate axis for the real part. The localization of the measurement values in the complex representation plane is compared to a desired profile, and the measurement values are adjudged to be not plausible if a predefinable deviation from the desired profile is exceeded.

In accordance with an example embodiment, a body-weight sensing scale includes cardio-based physiological sensing circuitry to detect heart characteristics of a user, and provide outputs indicative of the detected heart characteristics. A processor circuit is arranged with the cardio-based physiological sensing circuitry to process data to provide a noise-reduced cardiogram signal which characterizes functionality/health of the user's heart.

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.
