Leonardo mechanography

Leonardo mechanography enables objective automatic motion analysis and performance analysis. It allows early diagnosis of movement disorders, objective and reproducible assessment of muscular performance and flexibility as well as the documentation of changes.

Analysis concept

The main objective of Leonardo mechanography is to provide efficient quantification of functional human motion based on physical parameters. Leonardo mechanography analyses functional everyday movement patterns because results are highly reproducible across a large age group from children to the elderly. Leonardo mechanography offers essential advantages for clinical use, allowing the simple quantification of peak force, peak power and left-right differences of movement patterns. It requires no additional complex measurement devices, no time consuming subject preparation and is easy to use and results are produced within minutes.

Measurement method

Human movement can be quantified objectively based on the physical parameters.Essential for quantification of the power output of the human body are: force, velocity and time. Leonardo mechanography measures dynamic ground reaction forces and calculates the centre of mass related physical parameters including acceleration, velocity, energy, power, jumping height and stiffness or flexibility. In addition, asymmetries of the motion pattern can be analysed directly during a physiological movement since the ground reaction force platform is split into halves. The acquired spatial resolution of the measured forces allows stabilometric analysis, for example, during various types of balance tests.

Measurement results
