Dynamic modeling and simulation of free swinging shank for hemiplegics

The lower extremities of a humanoid model having the parameters of stroke patient is designed to promote an understanding of its paralysis behaviour. The assemblies of the model are designed using SolidWork, a three dimensional computer-aided design (CAD) software and converted into SimMechanics models for further simulations. The humanoid-lower extremities model is designed based on anthropometric data of a healthy human and modified accordingly to changes of body composition and weight of stroke patients. Difference of 0.56 kg between paretic and non-paretic leg might gives significant results in control simulations. The developed model can offer prediction and much insight into the nature of movement generation and behaviour of the real stroke system.
