Mechanography

from Wikipedia, the free encyclopedia

The mechanography (in the literature often called 'jumping Mechanography' 'denotes') is a diagnostic measuring method of the medicine, which, on the basis of the time profile of the floor reaction forces in typical everyday movements such as jumps or getting up from a chair, center of gravity related physical parameters such as speed, power Jump height and total body stiffness determined. If the floor reaction forces are recorded separately for the left and right leg, then side differences in the temporal course of the physical parameters can also be determined, which make it possible, for example, to quantify the course of therapy. The same analysis method can also be used in the context of gait analysis or when climbing stairs.

Classic areas of application for mechanography are geriatrics and pediatrics.In contrast to many other measurement methods (pure time measurement in the widespread Chair Rising Test, Standup and Go test, etc.), for example, the body weight-related peak performance when jumping with both legs at maximum height is a measurement value that is much more reproducible , which also shows no significant training effect even with frequent use.

On the basis of this test, Runge et al. a. and Schönau u. a. Reference values ​​for assigning individual performance levels depending on gender and age to a so-called optimally aging reference collective. Tsubaki was able to show that using identical selection criteria for a typical Japanese population resulted in identical performance data to the Western European reference group of Runge. It can therefore be assumed that no country-specific reference data need to be collected for mechanography. Runge u. a. also showed a connection between the individual performance recorded by means of mechanography and the neuromuscular risk of falls.

Due to the objective and easily reproducible quantification of everyday movement sequences in physical quantities, mechanography is particularly suitable for determining the current performance of a person and for documenting training or therapy successes. For this reason, Mechanography is also used as one of the standard measurement methods in current and future bed-rest studies by the European Space Agency ( ESA ).

Mechanography is also used to quantify the relationships between muscles and bones. According to the Mechanostat theorem, muscle function influences bone formation. This muscle-bone relationship can be quantified in vivo by combining measurement methods for determining muscle function, such as mechanography and computed tomographic measurement methods, such as quantitative computed tomography, to determine bone density , bone geometry and bone strength.
