Background and Purpose: Basically, The muscle spindle is innervated by γ – fibers, γ – fibers are divided into phasic and tonic groups on the basis of their function. Ït is believed that phasic one γ innervate all the muscle spindle fibers where as tonic one innervate only tonic muscle spindle fibers and phasic of type two. The purpose of this study was to observe the fiber activity during ph...
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...
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...
Objective: Trigger points may result in referral pain of their close areas. Recent evidence suggests that latent trigger points although they are not sensitive enough to cause pain, can interfere with the normal muscle function. These myofascial trigger points are estimated as an electro-physiological phenomenon. However, there are a few studies which investigated the effect of these points on ...
Background: Many workers, especially welders, have awkward postures during their working hours. Evaluating such kind of postures is done with the aim of corrective actions. Therefore, the present study was conducted to evaluate the activity of welder's muscles in common welding postures working on gas transmission pipelines. Methods: This cross-sectional descriptive-analytical study was perfor...
Increased metabolic activity in muscle secondary to excessive muscle activity during the uptake phase and shortly before FDG injection is a known phenomenon. We present FDG PET/CT findings in a young male, known case of carcinoma maxilla His scan showed diffuse increased metabolic activity in multiple skeletal muscle groups. There was history of unaccustomed, strenuous sports activity of skiing...
Introduction: The manufacturing, service professions, and other occupations commonly require their employees to spend more than 2 hours of their workday in an upright position which can potentially cause temporary or permanent health effects. The objective of this study is to determine the effect of anti-fatigue mats on leg muscle discomfort and muscle activity due to prolonged standing. Mater...
background: workstation design has shift from using single monitor screen to dual monitor screens, which may impose some impacts towards the muscles activity. this study aimed to determine the effect of using dual monitor screen computer to the neck-shoulder muscle activity among computer user. method: this experimental study was conducted in 2015 among 28 healthy students in university malaysi...
Background and Objectives: Myocyte enhancer factor 2c activates the genes of the slow-twitch muscle, the muscle which plays role in endurance activity. Therefore, the aim of this study was to evaluate the effect of a program of intensive endurance activity on MEF2c gene expression in fast and slow twitch skeletal muscles in wistar rats. Materials and Methods: In this experimental study, 14 mal...
the antinociceptive effect of elaeagnus angustifolia fruits was studied in mice. the antinociceptive effect of ethanolic and boiling water extracts was studied using two thermal stimuli, the hot-plate and tail-flick tests. the intraperitoneal and oral administration of the ethanolic extract of seed 0.75-7.00 g/kg), but not pericarp and medulla had significant antinociceptive activity in the hot...
