Evaluating the ability of movement preprogramming in elderly and in Parkinsonian subjects is known to be important for clinical diagnosis and for rehabilitation purposes. Employing cyclical two-target reaching tasks (Fitt’s tasks) a new cinematic analysis of forearm movements is performed [1]. We extract a new Index of Preprogramming (IP) which relates to the standardization of cinematic patterns. Another index (R2) quantifies nonlinearities [2] that on-line control introduces in the patterns due to corrective strokes.

Abstract

Evaluating the ability of movement preprogramming in elderly and in Parkinsonian subjects is known to be important for clinical diagnosis and for rehabilitation purposes. Employing cyclical two-target reaching tasks (Fitt’s tasks) a new cinematic analysis of forearm movements is performed [1]. We extract a new Index of Preprogramming (IP) which relates to the standardization of cinematic patterns. Another index (R2) quantifies nonlinearities [2] that on-line control introduces in the patterns due to corrective strokes. Present indexes can be employed together with known preprogramming indexes based on counts of corrective strokes [3] and they allow for a more accurate evaluation of the motor control strategies used by the subject.
