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...
background: stabilization exercises can improve the performance of trunk and back muscles, which are effective in the prevention and treatment of low back pain. the four-point kneeling exercise is one of the most common types of stabilization exercises. this quasi-experimental study aimed to evaluate and compare the level of activation between abdominal and lumbar muscles in the different stage...
Purpose: The patellofemoral pain syndrome (PFPS) is one of the most common musculoskeletal disorders of the knee joint. Hip muscles’ weakness is one of the reasons for PFPS occurrence. The aim of this study was to recognize the effective muscle group in prevention and treatment of patients with PFPS. Methods: This is a prospective and quasi-experimental study in which 30 participants (15 ...
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...
To understand the connection among brain and facial muscles, we decoded correlation of muscles activities. We applied information theory (Shannon entropy) to EEG EMG signals recorded from 12 subjects (7 M, 5 F) during rest stimulation using three odors (pineapple, banana, vanilla). The results indicated that a larger variation in molecular complexity causes signals. Therefore, muscles’ activity...
Background and Objective: Pronated foot is one of the most common abnormalities associated with navicular drop and may be influenced by the hip muscles. The purpose of this study was to examine the effect of a strength exercise program on the hip abductor and lateral rotator muscles in pronated foot. Materials and Methods: This study was a randomized clinical trial of pre-and post-test. Thi...
background and aim: creatine is an energy-supplying protein in neuromuscular system with a protective role in relieving neurological symptoms. since the enzymes and other mechanism involved in the conversion of creatine in the inner ear and vestibular nuclei are found in abundance, the aim of this study was to measure the effects of creatine on cervical vestibular evoked myogenic potentials (cv...
introduction: transcranial magnetic stimulation (tms) is a useful tool for assessment of corticospinal excitability (cse) changes in both healthy individuals and patients with brain disorders. the usefulness of tms-elicited motor evoked potentials (meps) for the assessment of cse in a clinical context depends on their intra-and inter-session reliability. this study aimed to evaluate if removal ...
The role of respiratory muscles in acute changes of circulation and ventilation due to acetylcholine in anaesthetized spontaneously breathing rabbits was investigated. Significant increase of end-expiratory thoracic circumference and insignificant increase of abdominal one was found and was taken as a measure of changed respiratory muscles tone. The authors emphasize the important role of the r...
