... using only 15 s of collected data. In conclusion, this study illustrates that an RL approach can be an alternative technique to conventional inverse dynamic analysis in human biomechanics study and EMG-driven human-machine interfacing applications. The proposed RL method uncovers meaningful...

The data presented here complements previous publications, which, all together, allow researchers to build a biomechanical model of the upper limb including a reverse shoulder prosthesis. multibody system dynamics musculoskeletal model inverse dynamics shoulder joint reverse shoulder...

... was to converge on a set of muscle parameters and coefficients which minimized the difference between the model-computed knee extensor moments and the moments computed from inverse dynamics. The medial thrust and normal walking trials were tuned at the same time and although we did attempt to weight the objective...

...Raziel Riemer, Ph.D.; Elizabeth T. Hsiao-Wecksler, Ph.D. Two main sources of error in inverse dynamics based calculations of net joint torques are inaccuracies in segmental motions and estimates of anthropometric body segment parameters (BSPs). Methods for estimating BSP (i.e., segmental moment...

...Joseph E. Langenderfer, Ph.D; Peter J. Laz; Anthony J. Petrella; Paul J. Rullkoetter Inverse dynamics is a standard approach for estimating joint loadings in the lower extremity from kinematic and ground reaction data for use in clinical and research gait studies. Variability in estimating body...

... FES technology. These findings suggest that FES-assisted arm-free standing of paraplegics is theoretically feasible, even when limited by the fact that muscles actuating specific DOFs are often denervated or difficult to access. functional electrical stimulation inverse dynamics paraplegia...

...Behzad Dariush; Hooshang Hemami; Mohamad Parnianpour Joint moment estimation using the traditional inverse dynamics analysis presents two challenging problems, which limit its reliability. First, the quality of the computed moments depends directly on unreliable estimates of the segment...
