Various kinds of command source can be used to control an above-elbow prosthesis. But none of them can be used to perform a specified task easily. The research is devoted to investigation of the potential effectiveness of applying the kinematic data of the shoulder joint to control an upper-limb prosthesis. Using these data as input signals, an appropriate(More)
In this paper, a general formula for nding the Maximum Allowable Dynamic Load (MADL) of geometrically nonlinear exible link manipulators is presented. The dynamic model for links in most mechanisms is often based on the small deeection theory but for applications like lightweight links, high-precision elements or high speed it is necessary to capture the(More)
INTRODUCTION Various neuroregenerative procedures have been recently employed along with neurorehabilitation programs to promote neurological function after Spinal Cord Injury (SCI), and recently most of them have focused on the acute stage of spinal cord injury. In this report, we present a case of acute SCI treated with neuroprotective treatments in(More)
Degenerative disc disease is one of the most common causes of low back pain instigating huge socioeconomic costs and posing an immense burden on healthcare systems worldwide. New therapeutic approaches to damaged intervertebral discs are therefore of great interest. Platelet-Rich Plasma (PRP) has been proposed for the repair and regeneration of degenerated(More)
The risk of low back pain resulted from cyclic loadings is greater than that resulted from prolonged static postures. Disk degeneration results in degradation of disk solid structures and decrease of water contents, which is caused by activation of matrix digestive enzymes. The mechanical responses resulted from internal solid-fluid interactions of(More)
BACKGROUND AND OBJECTIVE In magnetic fluid hyperthermia therapy, controlling temperature elevation and optimizing heat generation is an immense challenge in practice. The resultant heating configuration by magnetic fluid in the tumor is closely related to the dispersion of particles, frequency and intensity of magnetic field, and biological tissue(More)

SUMMARY The finite element method is used to analysis the spine's issue invasively. In this study, a new element is defined which consists a disc (Viscoelastic Euler Beam Element) and a vertebra (Rigid Link) as a unit element. The new element leads to reduce the run time of the models. Therefore, the models, made by the new element, can be easily analyzed(More)
A parametric 2D finite element model was developed for lower cervical spine (C3-C7) in sagital plane in this research. Being parametric, this model facilitates making changes in the geometrical sizes as well as omitting or modifying some parts of it in order to build a new model with special purposes. Application of geometrical parameters, the values of(More)
