Lower Back Injury Prevention: EMG behavior of the erector spinae muscle during fatigue
Level of Education of Students Involved
Dr. Bethany Luke
Lower back pain is a condition that affects a large subset of people in the workforce, and specialists are constantly investigating better ways to diagnose and treat lower back pain. In efforts to combat lower back pain and subsequent lower back injuries, we will assess if EMG signals possess muscle fatigue indicators that can provide early recognition of potential muscle overexertion in the erector spinae. In our study, electromyographic (EMG) signals will be captured via Delsys EMGworks surface electrodes and the signals will be processed with iWorx Teaching Assistant (TA) to detect changes in the erector spinae. Each subject will perform the deadlift exercise until the subject verbalizes feelings of muscle fatigue. The EMG signals from the subject’s erector spinae will be monitored before and throughout activity. The EMG signals will be band-pass filtered, then the frequencies demonstrated throughout the deadlift activity will be compared across all subjects to determine if a muscle fatigue indicator is demonstrated in the EMG signals.
