Shield crossing loess stratum will encounter many engineering problems such as excessive local soil deformation and ground collapse crater. Based on the phenomenon characteristics of caused by large-diameter shield strata, this paper summarizes curve, analyzes causes reaction deformation, main laws strata. And fuzzy mathematical method is used to analyze influencing factors provide theoretical ...
BACKGROUND Among other causes the long-term result of hip prostheses in dogs is determined by aseptic loosening. A prevention of prosthesis complications can be achieved by an optimization of the tribological system which finally results in improved implant duration. In this context a computerized model for the calculation of hip joint loadings during different motions would be of benefit. In a...
Mechanography is an innovative method to evaluate lower-limb dynamic muscle function. This technique is generally performed on force platforms that measure only the vertical component of ground reaction force (GRF). The underlying assumption is that medio-lateral and antero-posterior forces do not contribute significantly to the GRF in jumping and rising tests. The goal of this study was to est...
Background & Aim: Genu varum is one of the most common abnormalities of the knee joint in which the inner condyles of the femur move away from each other. The aim of the present study was to compare efficiency of exercise on the treadmill and ground on the ground reaction forces during walking in people with genu varum. Material & Methods: The present study was a quasi-experimental and laborat...
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 ...
Aims and background: Jumping and landing are common exercises in sports activities which are associated with injury of the anterior cruciate ligament. The purpose of this study was to investigate the effect of using a knee brace on peak ground reaction forces amplitudes, vertical loading rate, impulses in three dimensions and peak free moment values during landing in athletes with anterior cr...
Introduction: Most of the functional disorders in the foot are created by changes in the arch of the foot. The motion control shoes are designed to control the excessive rear foot motions. The aim of this study was to evaluate the effect of long-term use of motion control shoe on the ground reaction force components in individuals with functional pronated feet during running. Methods: The prese...
Objectives: Genu Varum deformity is known as a factor disrupting gravity line and force patterns in lower limb and may make the individual more exposed to lower extremity injuries especially in repeated activities like running. The aim of this study was to investigate Ground Reaction Forces in subjects with and without genu varum deformity during running. Methods: Thirty active men were divide...
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...
Objective: The link between frequency content of gait ground reaction forces and hearing loss is not well understood. The objective of this study was to investigate the effects of hearing loss on gait ground reaction force frequency content. Methods: Thirty male children were equally divided into a healthy group and a group with hearing loss problems (Deaf group). Frequency content of ground r...
