Most of the people over 65 years old, experience falling due to muscular-nerve system disorder. Control of posture for this group of people can be recovered by rehabilitation exercises. This study suggests an optimum kinematic motion pattern to recover stability and balance of the human body due to a suddenly base acceleration without separation of the foot from the ground, using statically and dynamically compensation algorithms. The work was done by mathematically simulation of a biomechanical multi-links model in the sagittal plane. The results showed that a continuous smooth motion in every joint can lead to recover the stability of the model

The kinematics and kinetics of human postural responses to anterior-posterior sudden forces was studied using a human multi-segments model in the sagittal plane. Forces and moments acted on the feet of the model were solved using Newton-Euler method. The stability criterion of the model is based on the center of pressure (COP) location, which is located in the area of contact with the ground between the toe and the heel positions. The postural responses of the model optimized using statically and dynamically compensation algorithms. Results of the analysis and dynamical simulation showed an improvement in response to external perturbation.
