Genu varus is one of the malalignment of the lower limbs, the failure to correct it leads to secondary abnormalities in adulthood. The purpose of this study was to investigate the effects of a corrective exercise program on ground reaction forces, loading rates, impulses and free moment during stance phase of walking. 17 children with genu varus were volunteered to participate in this study (Ag...
We present analytical results allowing to understand the influence of usually neglected vertical component of the Coriolis force and of the vertical velocity contribution in its horizontal component upon wave-trapping in shear flows in stratified fluid, and upon related inertial instability.
Background and Objectives: The prevalence of flexible flat foot in children was reported between 20 -78% in previous studies. Flat foot can result into mechanical deviations in lower limb alignment during walking. The purpose of this study was to evaluate the immediate effects of medical insole on loading rate, impulse, and free moment in children with flat foot during walking. Material and M...
Objective: The aim of this study was the comparison of plantar pressure distribution and vertical ground reaction force between dominant and none-dominant limbs in healthy through using Principle Component Analysis (PCA) technique. Materials & Methods: This study was quasi-experimental in which 20 healthy adult males and females were selected from available subjects. Subject’s plantar pressu...
objectives: foot and ankle problems are common complications in rheumatoid arthritis disease. gait pattern such as normal foot and ankle rocker is impaired in patients with rheumatoid arthritis. rocker sole as an external shoe modification is commonly prescribed in this pathology. the aim of this study was to investigate the effect of rocker shoe on vertical ground reaction force parameters dur...
Objective: in normal walking, repetitive vertical ground reaction forces are tansformed on musculo-skeletal system. Magnitude of force during impact is major contributor to overuse injuries. Purpose of this study was the evaluate to effect of standard and beveled heel at orthopedic shoe on vertical ground reaction forces during walking in healthy subjects. Materials & Methods: 30 healthy adu...
performance of structures during recent earthquakes shows that the effect of vertical component of earthquake (vce) could be considered as one of the main causes of bridges collapse. in most of bridge design codes, for seismic analysis of bridges, vce is not taken into account or a distinguished method isn’t presented for assessment of vce. in the present work, the effect of vce on two existing...
abstract introduction: in some individuals because of the poor functioning leg muscles, plantar arch drooping suffered and it seems that ground reaction force individuals with flat foot than to those with normal foot, due to reduced recruitment is altered by the arc. the aim of the present study the effect of corrective exercise program on the ground reaction force of student with flat food du...
Objectives: Foot and ankle problems are common complications in rheumatoid arthritis disease. Gait pattern such as normal foot and ankle rocker is impaired in patients with rheumatoid arthritis. Rocker sole as an external shoe modification is commonly prescribed in this pathology. The aim of this study was to investigate the effect of rocker shoe on vertical ground reaction force parameters dur...
Objective: The purpose of this study was to compare vertical ground reaction force during forward and backward walking among the male professional Karatekas with genu varum and normal knee. Methods: 20 professional male Karates (in genu varum and normal groups) participated in this semi-experimental study. The vertical ground reaction force was measured using force plate system during forward ...
