Influence of the Sampling Rate on the Measurements of the Upper Limb Movements

Article Preview

Abstract:

The main objective of the study consists in determination of the most appropriate sampling rate of the measurements in instrumented kinematic analysis of the upper limb movements. The measuring system involved in the study is Zebris CMS-HS Measuring System, whose configuration was defined by ultrasound markers attached to specific body sites. The sampling rate interval was set from 10 to 25 Hz, according to the system’s range of frequencies. The kinematic parameters which have been analyzed are shoulder and elbow flexion-extension and shoulder abduction-adduction. A comparative kinematical analysis of the angle variations of flexion-extension and abduction-adduction in shoulder joint and flexion-extension in elbow joint was performed for both left and right upper limbs at each sampling rate.
