Method and apparatus for measuring physical parameters, such as mass, and spring and damping constants, of a bone region of a human subject. The bone region is excited by a vibratory probe in a frequency range between about 70-1,600 Hertz and the, mechanical response of the tissue to the vibratory excitation is measured and converted to frequency-dependent force/displacement data. By correlating the force/displacement values determined from the force/displacement data with the behavior of a linear mechanical system having coupled bone and skin mass, the physical parameters which are contained in the equation of motion can be calculated.
