the facial esthetics after orthodontic treatment and orthognathic surgery may be affected by the patient's natural head position. the purpose of this study was to evaluate the natural head position for the three skeletal classes of malocclusion.our sample consisted of 102 lateral cephalometric radiographs of patients aged 15 to 18 years; class i (n=32), class ii (n=40) and class iii (n=30). nin...
background: musculoskeletal symptoms are the main cause of loss of working time, and increase in labor costs. poor posture is the most important risk factor for work-related musculoskeletal symptoms. this study aimed at evaluating the role of ergonomic risk factors in different surgical (open surgery, laparoscopy, and microsurgery) in the frequency or resonance frequency of musculoskeletal symp...
introduction: spinal malalignment is a common problem in the present societies and forward head posture is one of the most common dysfunction in cervical region. the purpose of the present study is to evaluate effect of stabilization exercises in improving of forward head posture. materials and methods: twenty six female students with forward head posture in age range of 20-27 years old partici...
Background: Aim of current study was to investigate the effect of changes of lumbar posture on postural balance in non specific choronic low back pain patients while applying axial load. Methods : In this experimental analytic study, 10 Non Specific Choronic Lo Back Pain NSCLBPwomen patients and 10 healthy volunteers that were matched together, evaluated. Postural sway of participants in ne...
Sensory-motor control of upright human posture may be organized in a top-down fashion such that certain head-trunk coordination strategies are employed to optimize visual and/or vestibular sensory inputs. Previous quantitative models of the biomechanics of human posture control have examined the simple case of ankle sway strategy, in which an inverted pendulum model is used, and the somewhat mo...
The purpose of this study was to analyse the force output of handle and pedal as well as the electromyography (EMG) of lower extremity in different cycling postures. Bilateral pedalling asymmetry indices of force and EMG were also determined in this study. Twelve healthy cyclists were recruited for this study and tested for force output and EMG during steady state cycling adopting different ped...
The main goal of the study was to determine the types of body posture of boys (n = 273), 10 to 13 years of age, by means of the body posture assessment method based on the software Posture Image Analyzer. The results should enable better understanding of postural issues, as well as timely and more precise selection of kinesitherapeutic procedures. Values of 5 front view and 4 sagittal view indi...
INTRODUCTION The Valsalva manoeuvre (VM) is a recommended first-line physical treatment for patients with re-entrant supraventricular tachycardia (SVT), but is often ineffective in standard practice. A failed VM is typically followed by treatment with intravenous adenosine, which patients often find unpleasant. VM effectiveness might be improved by a modification to posture which exaggerates th...
