Kinematic modeling of head-neck movements

The main objective is to generate kinematic models for the head and neck mo vements, The motivation comes from our study of individuals with, quadriple gia and the need to design rehabilitation aiding devices such as robots and teletheses that can be controlled by head-neck movements, It is then neces sary to develop mathematical models for the head and neck movements, Two id entification methods have been applied to study the kinematics of head-neck movements of able-body as well as neck-injured subjects, In particular, sa gittal plane movements are well modeled by a planar two-revolute-joint link age. In fact, the motion in joint space seems to indicate that sagittal pla ne movements may be classified as a single DOF motion. Finally, a spatial t hree-revolute-joint system has peen employed to model three-dimensional hea d-neck movements.
