SwayTest

The traditional way of evaluating a person's balance is by estimating the displacement of the Center of Pressure (COP), which is acquired with a force platform. Force/pressure platforms use the ground reaction force of the subject to calculate COP displacement. This COP displacement is then used to evaluate Center of Mass (CoM) movements. This can be regarded as an indirect approach. Moreover, the necessary equipment for this is expensive and not portable. With the MoveTest body sway module COM accelerations and angular velocities can be measured directly and in any location.

Method

The DynaPort MT measures 3-dimensional accelerations and angular velocities. Based on these signals AP and ML velocities and displacements are determined. Finally, sway quality is expressed by jerk, frequency content, variability, and displacement parameters.

Research

DynaPort measurements have been used to: differentiate individuals at high risk for Parkinson’s disease from controls [1], differentiate between subjects with various levels of athletic skill [2], determining balance strategy [3].
