Abstract
A method of analyzing a composition of a human body having a plurality of body segments is disclosed. The method can include applying a current signal to a body. The method can further include simultaneously measuring a plurality of voltage signals from a plurality of measuring positions of the body during a predetermined period, and processing at least two of the plurality of voltage signals to determine a composition parameter of a body segment so as to assess or analyze composition of the body.
Claims23
A method of assessing composition of a body comprising a trunk and four extremities attached thereto, the four extremities comprising first, second, third and fourth extremities, the method comprising:
- applying a first current signal between the first and second extremities;
- applying a second current signal between the third and fourth extremities;
- simultaneously measuring at least one voltage signal at a distal end portion of each of the four extremities;
- obtaining a first voltage drop signal between the distal end portion of one of the four extremities and the distal end portion of another of the four extremities;
- computing a first value indicative of impedance between the two distal end portions using the first voltage drop signal and the first current signal;
- obtaining a second voltage drop signal between the distal end portion of one of the four extremities and the distal end portion of another of the four extremities, wherein at least one of the two distal end portions used for obtaining the second voltage drop signal is not either of the two extremities used for obtaining the first voltage drop signal;
- and
- computing a second value indicative of impedance between the two distal end portions using the second voltage drop signal and the second current signal.
A method of analyzing composition of a body, the method comprising:
- establishing contact of current electrodes with four extremities, each extremity contacting at least one of the current electrodes;
- establishing contact of voltage measuring electrodes with the four extremities, each extremity contacting at least one of the voltage measuring electrodes;
- applying a first current signal between first and second extremities through a body via the current electrodes contacting the first and second extremities;
- simultaneously with applying of the first current signal, applying a second current signal between third and fourth extremities through the body via the current electrodes contacting the third and fourth extremities;
- simultaneously measuring voltage signals from the voltage measuring electrodes contacting the four extremities;
- and
- processing a first set of voltage signals among the measured voltage signals to determine a composition parameter of a first portion of the body based on the first set of voltage signals and the first current signal, and further processing a second set of voltage signals among the measured voltage signals to determine a composition parameter of a second portion of the body based on the second set of voltage signals and the second current signals, wherein the composition of the body is assessed using at least the determined composition parameters.
