Title: APPARATUS AND METHOD FOR ASSESSMENT OF A CHARACTERISTIC OF A BONE
Abstract:
A system to facilitate determination of a physical characteristic of a bone including in particular the bone mineral density (BMD) comprises a handheld tapper device having a solenoid or an electric vibration motor configured to provide a quantitative impact force as one or a series of strikes (using a solenoid) or in the form of continuous vibration (using an electric vibration motor) at a bone of a subject so as to induce vibrations in the bone. Vibration signal(s) are identified and the signal processed and analysed according to at least one analysis method including for example artificial neural networks, clustering, regression analysis, principal component analysis and discriminant analysis.
