Muscle Coordination Retraining to Reduce Knee Loading

Experimental data and simulation results from ten healthy individuals walking on an instrumented treadmill. Participants were provided with real-time biofeedback instructing them to walk with greater soleus muscle activation and less gastrocnemius activation, with the goal of reducing knee contact force. A custom static optimization code that incorporated EMG into the muscle redundancy solution was used to estimate the effect of the altered coordination pattern on knee contact force.The manuscript using these data and simulations can be found here:Uhlrich, S.D., Jackson, R.W., Seth, A.

本数据集包含了十位健康个体在仪器化跑步机上行走时的实验数据和仿真结果。受试者在实时生物反馈的指导下，被要求增强比目鱼肌的激活程度，并减少腓肠肌的激活，旨在降低膝关节接触力。本研究采用了一种将肌电图（EMG）纳入肌肉冗余解决方案中的定制静态优化代码，以评估改变协调模式对膝关节接触力的影响。基于这些数据和仿真结果所撰写的论文可在以下链接查阅：Uhlrich, S.D., Jackson, R.W., Seth, A.
