Recent studies provide further support for the hypothesis that spatial representations of limb position, target locations, and potential motor actions are expressed in the neuronal activity in parietal cortex. In contrast, precentral cortical activity more strongly expresses processes involved in the selection and execution of motor actions. As a general conceptual framework, these processes ma...
Speaker Name: David M. Panicek, MD Department of Radiology Memorial Sloan-Kettering Cancer Center, New York, NY [email protected] Highlights • MRI enables accurate diagnosis of certain primary and secondary bone tumors based on their tissue composition, morphology, and/or associated marrow edema pattern. • MRI provides essential details about the local extent of bone tumors, which allows accur...
background and aim: motor vehicle accidents are common cause of mortality, morbidity and disability. human factors are principle cause for frequency of motor vehicle accident. in most studies, 52-40% lower limb injuries are trauma from a motorcycle accident. these accidents cause high financial cost and harm for society. materials and methods: in this study, patients with lower limb injuries re...
objective: to evaluate the predictive value of some biochemical markers in the outcome of extremity vascular trauma. methods: this study comprised 30 patients with traumatic arterial injury and acute limb ischemia referred to namazi hospital affiliated with shiraz university of medical ssciences, over a period of 8 months, from sep 2009 to jul 2010. venous blood samples were drawn from distal i...
The authors report a series of 43 patients suffering from lower limb pain, almost constantly associated with chronic or acute backpain, treated by microsurgical nerve root decompression and by implantation of a soft intervertebral prothesis (DIAM). Satisfying results were obtained in 97% of cases, inducing the authors to consider the device a reliable tool for curing low-back pain and sciatica....
Evolutionary thinking in medicine draws both on the phylogenetic history of Homo sapiens and on the dynamics of natural selection and genetic drift to give insight into antibiotic resistance, vaccine production, variation in drug response and reproductive biology. In the future, evolutionary developmental genetics promises to contribute to limb and nerve regeneration, and evolutionary functiona...
Aim and background : Annually about 200-500 million amputations occurring around world because of disease, trauma and congenital defects which approximately 85% are in limbs. For those with amputation the phantom limb pain is a serious problem and causes the therapeutic challenges for who need therapy. Present study was conducted to identify 18 month follow up efficacy Eye Movement Desensitiza...
Background: Traumatic amputation of upper limb above the level of the elbow, are rare injuries that a surgeon may be faced with a handful of cases during his career. Even with advanced techniques in microvascular surgery, the survival of the transplanted limb that cut off completely from the arm is relatively weak. Case Presentation: Four injured people (patient) in Imam Khomeini Hospital duri...
It is more than a decade since scientists are making use of sympathetic skin response (SSR) as a clinical and research method to evaluate sympathetic nervous system. A major portion of the efferent pathway of this response is composed of non-myelinated nerves. Thus, the latency of the response may be significantly different in normal individuals with different height and limb lengths. This stud...
Surface electromyographic (sEMG) signal has the potential to identify the human activities and intention. This potential is further exploited to control the artificial limbs using the sEMG signal from residual limbs of amputees. The paper deals with the development of multichannel cost efficient sEMG signal interface for research application, along with evaluation of proposed class dependent st...
