title = "Optimization of muscle parameters to predict ankle joint moments",
abstract = "In this study, an EMG-driven model was developed, and isometric and isokinetic contraction movements were evaluated to validate the developed model. One healthy male participated in this study. The dynamometer tasks were performed for maximum voluntary isometric contractions (MVIC) for ankle dorsiflexor and plantarflexor, isokinetic contraction at both 30°/s and 60°/s. EMGs were recorded from the tibialis anterior, gastrocnemius medialis, gastrocnemius lateralis and soleus muscles at the sampling rate of 1000 Hz. The MVIC trial was used to customize the EMG-driven model to the specific subject. Once the optimization was applied to adjust the muscle parameters, the predicted joint moment was highly similar to the measured value with the relatively small RMS error less than 40% (r = 0.955 (21%) and r = 0.819 (36%) and in 30°/s and 60°/s dynamic movements, respectively). We expect that our EMG-driven model would be employed in our future efforts to estimate muscle forces of the elderly.",
