Improving Computed Muscle Control through Optimization to Generate Dynamic Simulations of Overground Running
نویسندگان
چکیده
Numerical simulations are playing an increasingly important role in solving complex engineering problems, and have the potential to revolutionize medical decision making and treatment design. Musculoskeletal conditions cost the United States economy more than $849 billion per year (7.7% of the USA’s GDP) and place great demands on the healthcare system [1]. Simulations enable engineers and clinicians to ask “what if” questions that investigate musculoskeletal conditions and treatment outcomes. Specifically, forward dynamic simulations give insight into the complex interaction between neuromuscular control, musculoskeletal geometry, and observed multijoint movements.

Comparing the Effects of Fatigue Caused by the Treadmill and Overground Running on the Pattern of Plantar Pressure Distribution
Purpose: This study aimed to compare the effects of fatigue due to overground and treadmill running on the plantar pressure distribution pattern. Methods: Twelve novice athletes (Mean±SD age=26.0±2.5 y, Mean±SD weight: 52.0±3.0 kg, Mean±SD height: 159.0±5.0 cm), without sports injuries over the past year, were selected. Overground and treadmill running created fatigue in the samples. Peak pla...
متن کاملUsing computed muscle control to generate forward dynamic simulations of human walking from experimental data.
The objective of this study was to develop an efficient methodology for generating muscle-actuated simulations of human walking that closely reproduce experimental measures of kinematics and ground reaction forces. We first introduce a residual elimination algorithm (REA) to compute pelvis and low back kinematic trajectories that ensure consistency between whole-body dynamics and measured groun...
متن کاملMuscular Activity of Lower Extremity Muscles Running on Treadmill Compared with Different Overground Surfaces
The objective of this study is to compare the muscular activity of lower extremity muscles while running on treadmill and on overground surfaces. A total of 13 experienced heel-to-toe runners participated in the study. Electromyographic (EMG) data of four lower extremity muscles, including rectus femoris, tibialis anterior, biceps femoris, and gastrocnemius, were collected using the Noraxon EMG...
متن کاملModular Control of Treadmill vs Overground Running
Motorized treadmills have been widely used in locomotion studies, although a debate remains concerning the extrapolation of results obtained from treadmill experiments to overground locomotion. Slight differences between treadmill (TRD) and overground running (OVG) kinematics and muscle activity have previously been reported. However, little is known about differences in the modular control of ...
متن کاملGenerating dynamic simulations of movement using computed muscle control.
Computation of muscle excitation patterns that produce coordinated movements of muscle-actuated dynamic models is an important and challenging problem. Using dynamic optimization to compute excitation patterns comes at a large computational cost, which has limited the use of muscle-actuated simulations. This paper introduces a new algorithm, which we call computed muscle control, that uses stat...
