Emg of back3/29/2023 ![]() ![]() L5/S1 vertebral joint forces from EMGopt were sensitive to the expected variability of recorded EMG, but the magnitude of these differences (±4%) did not impact between-task comparisons. Compared to SOpt, the EMGopt approach predicted larger joint loads ( p<.01) with muscle activations better matching individual participant EMG patterns. Results showed the vertebral joint forces from the model were qualitatively similar in pattern and magnitude to literature reports. Further, model-estimated muscle activations were compared to recorded EMG, and model sensitivity to day-to-day EMG variability was evaluated. For evaluation, predicted lumbar vertebral joint forces were compared to those from a generic static optimization approach (SOpt) and to previous studies. Kinematic, external kinetic, and EMG data were recorded from six participants as they performed walking and carrying tasks on a treadmill. ![]() In this study we developed the framework for incorporating an electromyography optimization (EMGopt) approach within OpenSim ( ) and evaluated lower back demands estimated from the model during gait. Participant-specific musculoskeletal models are needed to accurately estimate lower back internal kinetic demands and injury risk. ![]()
