摘要：
Apparatus for use in performing impedance measurements on a subject comprising - respective pairs of excitation and detection electrodes for placement on upper and lower extremities of the subject； and - a processing system that is configured to: a) result in voltage excitation signals being applied to the subject, by means of excitation electrodes； b) detecting, by means of detection electrodes, current signals through the subject that are caused by the voltage excitation signals； c) determining an indication of a second signal through the subject, said indication of said second signal being a voltage from the center of the body at the center of the torso of the subject that is obtained from voltages that are detected by means of electrodes detection； d) use the indication of the second signal to determine if there is an unacceptable imbalance； and, e) if there is an unacceptable imbalance: i) determine modified voltage excitation signals according to the imbalance determined by: determining higher and lower impedances for the subject using the detected current signals, the voltage excitation signals and the tension of the center of the body； and, determining modified voltage excitation signals using said upper and lower impedances and an ideal current signal indication； and, ii) result in the modified voltage excitation signals being applied to the subject to thereby allow at least one impedance measurement to be made.Aparato para su uso en la realización de mediciones de impedancia en un sujeto que comprende - unos pares respectivos de electrodos de excitación y de detección para su colocación sobre extremidades superiores e inferiores del sujeto； y - un sistema de procesamiento que está configurado para: a) dar lugar a que unas señales de excitación de tensión se apliquen al sujeto, por medio de unos electrodos de excitación； b) detectar por medio de unos electrodos de detección, unas señales de corriente a través del sujeto que son causadas por las señales de e
