[ 1 ] - تأثیر خستگی بر الگوی فعالیت الکترومایوگرافی و هم انقباضی عضلات اندام تحتانی طی دویدن

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...

[ 2 ] - The Effect of Knee Osteoarthritis on Excursions of Lower Limb Joints During Gait

Purpose: This study aimed to investigate excursion changes at the hip, knee, and ankle joints during gait in patients with knee osteoarthritis (KOA) of varying severity. Methods: The method of research was causal-comparative (Ex Post Facto). A Vicon motion analysis system with 4 T-Series cameras was used to measure the kinematics variables. Fifteen normal subjects without KOA and thirty patien...

[ 3 ] - بررسی نیروهای عکس العمل زمین، ایمپالس و میزان بار وارد شده هنگام فرود متقاطع در بیماران مبتلا به کمر درد ارجاعی

 Aims and background: The purpose of this study was to compare the parameters of ground reaction force during landing in patients with chronic low back pain. Material and Methods: 21 healthy men and 21 men with chronic low back pain participated in this study. Using a Kistler force plate )1000Hz) GRF during landing was measured. Then, maximum GRF and their related time-to-peak, impulse and load...

[ 4 ] - Effects of backward gait training on Excursions of Lower Limb Joints of patients with medial knee Osteoarthritis

 Aims and background: The aim of this study was to investigate effects of backward gait training on Excursions of Lower Limb Joints in man Patients with medial knee Osteoarthritis. Materials and methods: The subjects were 21 healthy men and 42 male patients with knee osteoarthritis who were divided into experimental and control groups according to the Kellgren and Lawrence radiologic scale and ...

[ 5 ] - Effects of backward gait training protocol on knee adduction moment and impulse during walking in patients with medial knee osteoarthritis

Background and Aim: The aim of this study was to investigate the effects of backward gait training protocol on knee adduction moment and impulse in male patients with medial knee osteoarthritis. Materials and Methods: This quasi-experimental study with a pretest-posttest design included two control groups (healthy and patient) and an experimental group (subjects with medial knee osteoarthritis)...

[ 6 ] - تأثیر پروتکل تمرینی گیت به عقب بر پارامترهای فضایی- زمانی- مکانی راه رفتن بیماران مرد دچار استئوآرتریت زانو

مقدمه: تأثیر گیت به عقب بر متغیرهای بیومکانیکی راه رفتن بیماران دچار استئوآرتریت زانو ناشناخته‌اند. هدف این مطالعه تعیین تأثیر پروتکل تمرینی گیت به عقب بر پارامترهای فضایی- زمانی- مکانی راه رفتن بیماران دچار استئوآرتریت داخلی زانو است. مواد و روش‌ها: این تحقیق نیمه تجربی با طرح پیش­آزمون-پس آزمون در دو گروه کنترل (سالم مرجع و بیمار شاهد) و یک گروه تجربی انجام ...

[ 7 ] - Effect of Flat Foot on Excursions of Lower Limb Joints during Running

Introduction: The relationship between biomechanical parameters and different types of posture problems in association with running is unknown. Therefore, this study aimed to investigate the excursion changes at the hip, knee, and ankle joints during running in the patients with flat foot. Methods: The participants comprised 12 healthy men and 12 others suffering from flat feet disorder. They ...

[ 8 ] - Comparison of ground reaction forces and the amount of load introduced during crossover landing in people with flat foot and healthy individuals

Introduction: Investigating the risk factors during single crossover landing in people with flat foot complication is unknown. Therefore, the aim of the present study is to compare the ground reaction forces and the amount of load introduced during crossover landing in people with flat foot and healthy individuals.   Methods: The study method is descriptive-comparative. Twelve male subjects w...

[ 9 ] - Effects of Backward Gait Training on Ground Reaction Forces in Patients with Medial Knee Osteoarthritis

introduction: The aim of this study was to investigate the effects of backward gait training protocol on ground reaction forces in Patients with medial knee Osteoarthritis. Methods: This quasi-experimental study was performed with a pretest-posttest design in two groups of healthy and unhealthy and the experimental group (participants with medial knee osteoarthritis). The participants were 21 ...

[ 10 ] - Comparison of Plantar Force, Pressure and Impulse During Walking in Men and Women With Flat Feet

Objective: This study aims to compare the variables of plantar force, pressure and impulse during walking in men and women with flat feet. Methods: The study population consists of non-athlete students with and without flat feet. Of these, 48 (male and female) were selected as study samples. The peak pressure, force and impulse on the foot were measured during walking by a foot scanner at a sa...
