An economical method of recording peak pressures under the feet while standing or walking is described for clinical application. Normal values at 10 defined locations are presented. Correlation matrices indicate functional links between regions of support which influence patterns of deviation from the norms.
PURPOSE A flywheel system of variable inertia is described for inferring the mechanical properties of human muscle during a single explosive movement. METHODS The system consists of a lightweight aluminum disk mounted on a shaft onto which a driving cog is mounted. The inertia of the system can be varied from 0.024 to 0.69 kg.m(2) by attaching… (More)
This paper summarises a number of studies of human strength in tasks of static whole body exertion. Measurements were made using a transducer bar which allowed the simultaneous recording of the vertical and horizontal components of any force applied to it by the subject. In each experimental condition, each subject exerted his or herself in all directions… (More)
