2.2 Innovation in Biomedical Technology
Over the last 20 years we witnessed an extraordinary evolution and development
of biomedical systems. Thanks to the technological availability of new solutions
for sensing, computing and processing physiological data, the diagnostic capabil-
ity has reached a very fine resolution both in images and in chemical/biological
as well as biomechanical parameters. An example of these last systems are the
motion capture techniques applied to human movement analysis. Gait analysis
(Fig. 2.7 ) is the best known application.
It is an analysis of each component of the phases of ambulation and it is an
essential part of the diagnosis of various neurologic disorders and the assessment
