Device for lower extremity muscle force measurement in isokinetic movement conditions and procedure for the measurement carried out on the device
Abstrakt
Method of measurement of knee strength characteristics is carried out in a manner that measured person in upright position leans against dynamometers with bearing surfaces (3) and movable arm (2) and starts transition to the sitting position, thus acting on the movable arm (2), which through connected sensor (21) of angular position monitors speed of change in angular position of the movable arm (2) and acts on dynamometers with bearing surfaces (3), which measure strength generated by measured person for each lower extremity individually, whereas sensor (21) of angular position and dynamometers transmit collected data to control unit, which evaluates speed of change in angular position of movable arm (2) and visualization equipment (4) shows to measured person actual and requested speed of change in angular position of movable arm (2) in a manner that measured person adjusts speed of transition from upright to sitting position to requested speed.
