Traditionally, surgeons must do microsurgeries in a hunched posture because they need to look closely into the microscope. With Alcon TrueVision’s innovative heads-up, three-dimensional imaging technology, surgeons can now perform microsurgeries while sitting straight.

The goal of this project is to quantify the muscle fatigue level difference between the hunched and straight posture by capturing EMG signals from back and neck muscles.

Electromyography (EMG) is an electrodiagnostic medicine technique for evaluating and recording the electrical activity produced by skeletal muscles. Due to recruitment of motor units, the EMG signal amplitude shows an increase, whereas the frequency based mean or median frequency of the total power spectrum show a decrease over contraction time. We plan to record, analyze, and compare the EMG signals of the two postures: hunch and sitting straight for a long period of time.
