Characterization of fatigue induced hand tremor in laparoscopic surgical scenario is important in order to compensate its effect in robot assisted surgery (RAS). While the conventional analysis of muscle fatigue is highly varying in nature, there exists a constant search for fatigue induced hand tremor assessment and compensating device for surgeons to improve the quality of surgery. Moreover, detection of fatigue in dynamic activity itself is challenging. We have tried to address this issue by using a nonparametric method called empirical mode decomposition (EMD) of signals. Instead of analyzing the raw signals, spectral analysis of selective mode seems to be better for detecting the muscle fatigue in laparoscopic hand manipulation [1].

Hand tremor is the high frequency uncontrolled vibration of hand. One of the major causes for nonpathological hand tremors is the muscle fatigue. Effect of surgeons' hand tremor in laparoscopic surgery is crucial as it affects the...
