The human skeletal structure is modeled as a five-segment, four-degree-of-freedom mechanical system standing on sinusoidally driven tilting platform in the sagittal plane. The problem is formulated based on predictive dynamics method that leads to an optimization problem. The joint torque square is included in the performance measure and the dynamic stability is achieved by satisfying the vertical forces criterion. The constrained nonlinear optimization problem is solved using an algorithm based on the sequential quadratic programming (SQP) approach. The results which are joint trajectories and torques are characterized in terms of two main types of movement strategies observed in humans, namely, the ankle and hip strategies. Moreover, the effect of arms on the stability of the model is studied. The results obtained with the formulation are validated with the experimental data. Simulation results demonstrate the effectiveness of the proposed formulation in prediction of natural motion of human in response to tilting of the base plate.<\/jats:p>","DOI":"10.1142\/s0219843612500119","type":"journal-article","created":{"date-parts":[[2012,8,8]],"date-time":"2012-08-08T08:45:51Z","timestamp":1344415551000},"page":"1250011","source":"Crossref","is-referenced-by-count":0,"title":["OPTIMIZATION-BASED DYNAMIC PREDICTION OF HUMAN POSTURAL RESPONSE UNDER TILTING OF BASE OF SUPPORT"],"prefix":"10.1142","volume":"09","author":[{"given":"DAVOOD","family":"NADERI","sequence":"first","affiliation":[{"name":"Faculty of Engineering, Department of Mechanical Engineering, Bu Ali-Sina University, Hamedan, Iran"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"MOHSEN","family":"SADEGHI-MEHR","sequence":"additional","affiliation":[{"name":"Faculty of Engineering, Department of Mechanical Engineering, Bu Ali-Sina University, Hamedan, Iran"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"BEHNAM MIRIPOUR","family":"FARD","sequence":"additional","affiliation":[{"name":"Faculty of Engineering, Department of Mechanical Engineering, Bu Ali-Sina University, Hamedan, Iran"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"219","published-online":{"date-parts":[[2012,8,8]]},"reference":[{"key":"rf1","doi-asserted-by":"publisher","DOI":"10.1007\/s00158-009-0423-z"},{"key":"rf2","first-page":"1","volume":"62","author":"Potkonjak V.","journal-title":"Journal of Intelligent & Robotic Systems"},{"key":"rf3","first-page":"1","volume":"62","author":"Vukobratovic M.","journal-title":"Journal of Intelligent & Robotic Systems"},{"key":"rf4","doi-asserted-by":"publisher","DOI":"10.1007\/s00221-003-1481-x"},{"key":"rf5","doi-asserted-by":"publisher","DOI":"10.1109\/86.662618"},{"key":"rf6","doi-asserted-by":"crossref","first-page":"1369","DOI":"10.1152\/jn.1986.55.6.1369","volume":"55","author":"Horak F.
