This study investigated the patterns of rotational mobility (> or =20 degrees ) and stability (< or =20 degrees ) of the head and trunk in wild Indian monkeys during natural locomotion on the ground and on the flat-topped surfaces of walls. Adult hanuman langurs (Semnopithecus entellus) and bonnet macaques (Macaca radiata) of either gender were cine filmed in lateral view. Whole-body horizontal...

BACKGROUND Set-up errors are an inherent part of radiation treatment process. Coverage of target volume is a direct function of set-up margins, which should be optimized to prevent inadvertent irradiation of adjacent normal tissues. The aim of this study was to evaluate three-dimensional (3D) set-up errors and propose optimum margins for target volume coverage in head and neck radiotherapy. M...

in many structures, the applied lateral loads are comparable with gravity loads. these types of piles which are subject to high lateral load are usually divided into two categories including long and short piles. the general methods to estimate lateral bearing capacity of short and long piles are based on ultimate bearing capacity and allowable horizontal displacement respectively. in the prese...

objectives: patellar maltracking is the main reason for pain and disability in patellofemoral pain syndrome (pfps). patellar taping can considerably reduce such pain and disability. this study compared the effectiveness of physiotherapy exercises and kinesio taping on the patellar position in women with pfps (mean age 32.2±1.12 years) by using magnetic resonance imaging (mri). methods: thirty w...

purpose: controversy has recently risen about the presence of compensatory ocular countertorsion (coct) after head tilt. this study was performed to define the functional range of this phenomenon. methods: cycloplegic autorefraction was performed on 80 eyes with regular astigmatism 2d. objective autorefraction was performed in normal position, right and left head tilt positions of 5º, 10º, 15º,...

PURPOSE Proximal femoral ischemic deformities in the pediatric population is a challenging pathological situation. Many surgical techniques have been proposed to treat this problem, with variable reported results. We believe that a C-shaped pertrochanteric osteotomy plus neck lengthening utilizing distraction osteogenesis principles would restore the femoral anatomical ratios between neck, shaf...

Objective: In order to avoid the adverse consequences which cause by anthropogenic factor in the femoral neck fracture surgery and meet the requirements of selecting the most reasonable internal fixation way, from the viewpoint of biomechanics, an optimal selection system of internal fixation methods for femoral neck facture are established which integrates preprocessing, solving and post-proce...

OBJECTIVE To determine if medio-lateral motion of the head, trunk, or pelvis demonstrates dynamic stability as well as whole-body center of mass during obstructed walking. DESIGN Group comparison of two elderly populations using whole-body motion analysis. BACKGROUND Detection of imbalance through analysis of center of mass motion is commonly adopted, requiring three-dimensional reconstruct...

During an earthquake, significant damage can result due to instability of the soil in the area affected by internal seismic waves. A liquefaction-induced lateral ground displacement has been a very damaging type of ground failure during past strong earthquakes. In this study, neuro-fuzzy group method of data handling (NF-GMDH) is utilized for assessment of lateral displacement in both ground sl...
