muscle fatigue assessment has been the basis of numerous studies, specifically, in neuromuscular rehabilitation and the applications of fessystems. various emgbased techniques, in time and frequency domains, have been investigatedover years for the detection and evaluationof this phenomenon. the main objective of this study has beento evaluate the efficiency of applying a number of techniques w...
Background: The typical features of eccentric exercise-induced muscle damage are delayed-onset muscle soreness (DOMS) and prolonged loss of muscle strength. It has been shown that passive warmth is effective in reducing muscle injury. Due to the interaction of different systems in vivo, we used isolated perfused medial gastrocnemius skeletal muscle to study the direct effect of temperature on t...
purpose there is a decrease in quadriceps muscle strength in subjects with patellofemoral pain syndrome. various types of strengthening exercises of the quadriceps are done as part of its management, but the effect of isotonic eccentric quadriceps muscle exercises on patellofemoral pain syndrome has not been studied. hence the aim of this exploratory pilot study was to evaluate the effect of ec...
Objective: The purpose of this study was to determine the reliability of electromyography measurements of abdominal muscles activity during different manoeuvres (pelvic floor muscle (PFM) contraction, abdominal hollowing and abdominal bracing with and without PFM contraction) in subjects with and without chronic low back pain (LBP). Materials & Methods: In this methodology research 21 subjec...
bunium persicum (boiss.) is an economically important medicinal plant growing wild in arid regions in iran. the essential oil of b. persicum (eobp) was extracted using hydrodistillation. a total of eighteen compounds, representing 96.14 % of the oil was identified by gas chromatography/mass spectrometry (gc/ms).the main compounds were cuminaldehyde (23.04 %), gamma-terpinene (14.48 %), trans-3-...
Purpose: Motor control evaluation and analysis of it"s specifications for diagnosis of neuromuscular diseases is new approach in clinical electroneurophysiology, that is based on the changes of electromyography responses and classic reflexes in this field. In this study quantitative power spectrum frequency used for changes of motor control strategies. Materials and Methods: Twenty five health...
Objectives: The results of a few studies about the effects of ankle brace on muscles function during the performance of different tasks are contradictory. Moreover, the effect of brace on the co-contraction of ankle muscles is undiscovered. Therefore, the present study investigated the effect of brace usage on the ankle muscles activity and co-contraction during single-leg landing. Methods: Fi...
Background: Uterine bleeding is an important side effect of cesarean section which is due to non contractile uterine. The aim of this study was to compare the effect of 10% dextrose (IV infusion) and 40 IU/L oxytocin (IV infusion) on uterine contraction. Materials and Methods: This research was a double-blinded randomized clinical trial (RCT) study. 120 women were equally included in the tw...
Background: Muscle fatigue has been known to influence brain activity, but very little is known about how cortical centers respond to muscle fatigue.Objective: This study was conducted to investigate the effects of muscle contraction and fatigue induced by two different percents of maximal voluntary contraction (MVC) on Electroencephalography (EEG) signals.Material and Methods: In t...
