Mechanography
Purposeassessment of muscle function

Mechanography (also referred to as jumping mechanography or Muscle Mechanography[1]) is a medical diagnostic measurement method for motion analysis and assessment of muscle function and muscle power by means of physical parameters. The method is based on measuring the variation of the ground reaction forces over the time for motion patterns close to typical every day movements (e.g. chair rise or jumps). From these ground reaction forces centre of gravity related physical parameters like relative maximum forces, velocity, power output, kinetic energy, potential energy, height of jump or whole body stiffness[2] are calculated. If the ground reaction forces are measured separately for left and right leg in addition body imbalances during the motions can be analysed. This enables for example to document the results of therapy.[3][4] The same methodology can also be used for gait analysis[5][6] or for analysis of stair climbing,[7] grip strength[8] and Posturography.[9] Due to the utilization of every-day movements reproducibility is high over a wide age range[10]
