Effects of unstable footwear on joint reactions and muscle forces: an inverse dynamics study
نویسندگان
چکیده
Background Unstable shoe designs should support the muscle activity and promise the treatment of leg, back and foot problems. According to manufacturers, they should activate additional muscles and reduce joint reaction forces. Goal of this study is to investigate the effect of an unstable shoe design to gait patterns of healthy volunteers and by the means of inverse dynamic multi-body simulation.

Estimation of muscle forces and joint moments using a forward-inverse dynamics model.
PURPOSE This paper presents a forward dynamic neuromusculoskeletal model that can be used to estimate and predict joint moments and muscle forces. It uses EMG signals as inputs to the model, and joint moments predicted are verified through inverse dynamics. The aim of the model is to estimate or predict muscle forces about a joint, which can be used to estimate the corresponding joint compressi...

متن کاملAssessment of External and Internal Loads in the Triple Jump via Inverse Dynamics Simulation
THE TRIPLE JUMP IS A DEMANDING ATHLETICS EVENT THAT, AFTER AN APPROACH RUN, CONSISTS OF THREE CONSECUTIVE PHASES: the hop, the bound, and the jump. During the involved three take-off actions a jumper is exposed to increased risk of injury due to the high impact forces from the ground and powerful muscle/tendon efforts, which are further reflected in the internal loads of the lower limb joints. ...
متن کاملUsing a Cocontraction Ratio to Predict Antagonistic Behavior during Elbow Motion
Inverse dynamics methods for muscle forces prediction are globally unable to predict antagonistic activity during a joint motion. This is due to a lack of physiological information describing how forces are shared between flexors and extensors. The aim of this study is the definition and the use of a new EMG-based cocontraction ratio in an inverse dynamics muscle forces prediction approach appl...
متن کاملStability Assessment of the Flexible System using Redundancy
In this study, dynamic behavior of a mooring line in a floating system is analyzed by probability approaches. In dynamics, most researches have shown the system model and environments by mathematical expression. We called this process as the forward dynamics. However, there is a limit to define the exact environments because of uncertainty. To consider uncertainty, we introduce the redundancy i...
