INTRODUCTION Biomechanical studies of spine range of motion (RoM) and electromyography (EMG) typically focus on the lumbar region. The thoracic spine remains a topic less investigated in the literature, especially in terms of complex/relative motion coupled with EMG patterns. Research on complex motion patterns of the thoracic spine is directed towards kinematic measures only [1, 2] and usually...
among the low–dimensional allotropes of carbon, nanotubes and graphene have attracted very much attention from nano–science and nanotechnology specialists. they have been proposed as building blocks in nanometer device engineering. however, these structures are not defect–free. in this thesis, we focused on defective carbon nanotubes and graphene, and studied the effect of couple of very common...
background hamstring muscles play an important role in functional activities and relaxation and most people around the world suffer from the shortened muscles. different methods of repairing were suggested and there were disagreements with regard to determination of one technique with high efficiency. objectives this study aimed to introduce more effective method, either a static stretch or hol...
in this research we have studied the effect of some transition-metals (cu, ag and au) substitutions on two-electron reduction potential of flavins by application of dft method. all geometries have been optimized at blyp level of theory and “6-31+g** + lanl2dz” mixed basis set. the frequency job at the same method and basis sets has been performed to obtain gibbs free energy of compounds. it h...
In spite of the large number of papers written on the subject of low-back pain, the condition remains a most perplexing one for the average medical practitioner, both from the view-point of diagnosis and of treatment, and the orthopedist is not wholly successful in the handling of these cases. If one understands the mechanics of the spine as Goldthwait has so repeatedly taught in his many excel...
بررسی تأثیر آینهدرمانی بر دامنه حرکتی مفاصل اندامهای فوقانی و تحتانی در بیماران مبتلا به سکته مغزی
Background & Aim: Stroke is a major cause of disability. Developing new treatment approaches in order to improve and enhance post stroke recovery process is critical. The aim of this study was to determine the effect of mirror therapy on motion range of extremities of patients with stroke . Methods & Materials: This semi-experimental study was conducted among 50 patients with stroke hosp...
one of the debates concerning concepts of “medial motion” and “traversal motion” is the question of which of these two concepts of motion corresponds to motion in the corporeal world. in the present article we intend to employ the language of mathematics to present a model for each of these two concepts to study the above mentioned problem. as a result, medial motion represents a covering funct...
The goal of the present study was to determine the effects of prolonged, intermittent flexion on trunk neuromuscular control. Furthermore, the potential beneficial effects of passive upper body support during flexion were investigated. Twenty one healthy young volunteers participated during two separate visits in which they performed 1 hour of intermittent 60 seconds flexion and 30 seconds rest...
Adjacent segment deterioration (ASD) is a serious sequela of spinal fusion surgery that has recently become much more widespread due to an increasing number of spinal fusions performed [1]. Moreover, previous studies [2] of potential risk factors for ASD have found that instrumentation, posterior lumbar interbody fusion, injury to the facet joint of the adjacent segment, fusion length, age, and...
