A system for analysing surgical motion under a surgical visual aid

A system for evaluating the hand motion under surgical visual aids is discussed. The system consists of a set of visually guided motor tasks, a method of tracking the hand motion and a set of techniques for analyzing the movement data. Visually guided motor tasks abstract the surgical motion to enable performance by non-surgeons. The movement data is analyzed to identify the motion elements such as motion induced by measurement system noise, motion due to physiological tremor, motion due to myoclonic jerk, drift and voluntary dexterous motion. Empirical mode decomposition is used as the method to analyze the motion data along with its frequency plot to verify that the decomposed signals indeed correspond to the respective processes. Early results of the complex multicomponent data is reported with the extraction of the voluntary movement and the involuntary movement data.
