Understanding how stretch sensitive reflexes contribute to the coordination of whole arm posture and movement is best understood in the context of multijoint perturbations. However, it is difficult to assess the mechanisms contributing to reflex activity during such unconstrained tasks due to the uncertainties associated with estimating the relative importance of biomechanical and neural coupling...
Bone mass loss caused by microgravity is considered as one of the worst influences to human body during long-term spaceflight. As one of the countermeasures to retain bone mass, muscle electrical stimulation is just started in spaceflight application and needs further research. This work is aimed to investigate the effects of muscle electrical stimulation based on the tail-suspended rat experiment...
A four-segment biomechanical model and a control characterizing the action of the central nervous system (CNS) are used to investigate optimization of the postural stabilization process and the execution of voluntary movement. The point-to-point voluntary movement is optimized using different measures of performance (cost functions) in the time- and frequency domains. In particular kinematic measure...
A large mandibular discontinuity defect is most often due to severe trauma, infection or resection for neoplasm. Reconstruction plates have been popularly applied to bridge mandibular defects without bone grafting. The esthetics and continuity of the mandible with segmental defects could be rehabilitated successfully. However, the function is difficult to reconstructed using this type of plate. Furthermore,...
The anatomical human structure recognition is very important and necessary during the development of computer-aided diagnosis (CAD) system. In this paper, we propose an image processing scheme that can recognize the general structure of human torso by identifying the human torso region from CT images automatically and separating it into 7 parts: skin, subcutaneous fat, muscle, bone, diaphragm, thoracic...
