Abstract

This paper proposes and compares two methods for the automatic detection of force adaptation disturbances from recorded kinematic and kinetic signals of periodic hand movements. Line-oriented spectrum and cross-correlation analysis are examined as methods for the evaluation of periodic acceleration and grip force hand movement signals, thereby opening novel ways for the automatic assessment of force adaptation quality. The results obtained for three representative probands with the two methods are presented in some detail, and an overview of the results obtained with 24 probands is given
