abstract objectives: the purpose of this study was to investigate the relationship between core stability and lower extremity injuries in female athletes through functional tests. decreased core stability has been suggested to contribute to the etiology of lower extremity injuries. so far researches had been used non-functional tests to assess the core stability. material and methods: fifty col...
Despite the importance of core muscles in kinetic chains, the importance of each muscle compared to others has rarely been investigated. The purpose of this study was to compare the effect of each core muscle fatigue on lower extremity function tests. This quasi-experimental study with a pretest-posttest design was performed on 30 physical educations, female students with the mean age of 23.46±...
Purpose: Postural control preserves organs and body parts in a proper biomechanical stance which exists in two forms: static and dynamic. Fatigue is one of the factors that affects postural control. This study aimed to compare the electromyography (EMG) activity of the lower extremity muscles before and after fatigue. Methods: This study was descriptive correlational and based on the research ...
the relationship between proximal and distal lower limb muscle activities with time to stabilization
abstract introduction: identifying factors which cause the high incidence of acl is of great importance .the anterior shear forces are the primary mechanism of load sustained on the acl. during exercise, the activity of muscles and position of lower limbs may increase or decrease the anterior shear force. the purpose of this study is to investigate the relationship between the activity level of...
Background: The purpose of this study was to investigate the effects of ankle sprain on the electromyographic activity of distal and proximal muscles of lower extremity. Data Source: A full literature electronic search was performed using google scholar, Science direct, Ovid database. The following keywords were used: Functional ankle sprain, Electromyography, Perturbation, Gluteus maximus, Gl...
Purpose: Less attention has been paid to the electromyographic activity of the lower extremity muscles, which is considered as an essential part of the kinetic studies on the gait of mentally retarded individuals. Hence, the study aims at determining the surface electromyography characteristics of the lower extremity muscles of mentally retarded adolescents during walking. Methods: It is a cau...
Purpose: The proper neuromuscular recruitment patterns of hip and knee muscles are essential for dynamic stabilization of the knee. According to the kinematic chain, weakness in the performance of one motor segment can affect other segments of motion. Thus, the aim of this study was to compare the isometric strength of selected muscles of lower extremities in the hyperpronated foot with t...
Background: Muscle fatigue can change the muscle activation pattern during running and causes some disorders in running biomechanics. The aim of present study was to determine the effect of muscle fatigue on electromyographic activation pattern and co-contractions of lower extremity muscles during running. Methods: Fourteen males (age: 23.76±2.14 years, weight: 78.45±2.54 kg, hei...
Background and purpose: Previous research has shown that improving lower extremity muscle strength plays an important role in prevention of falls in older people. The aim of this study was to investigate the relationship between the changes of lower extremity muscle strength and postural control ability in elderly after a hydrotherapy program. Materials and methods: In a clinical trial, 30 eld...
[Purpose] The purpose of this study was to investigate the immediate effect of proprioceptive neuromuscular facilitation on muscle tone and muscle stiffness in stroke patients. [ Subjects and Methods] The subjects consisted of 15 patients with chronic stroke (stroke group) and 15 healthy persons (healthy group). We measured the effects of proprioceptive neuromuscular facilitation intervention o...
