Method for Evaluating Motor Synchronization and Short-term Motor Memory Based on Forearm Synchronization Process to Sinusoidal Motion Visual Stimulus

Abstract

Neurological problems can manifest in body movements. Pronation and supination of the forearms are used to evaluate the performance of diadochokinesis. Diagnosis in the clinic is subjective and nonquantitative. Introducing a sinusoidal visual stimulus, a novel measuring and evaluating method for human motor control function in a motor synchronization process has been proposed. The Non-Smoothness Measure (NSM) and movement speed measure (P3r) are confirmed in this study as promising evaluation parameters based on experiments on age groups.
