BACKGROUND Neck-shoulder pain conditions, e.g., chronic trapezius myalgia, have been associated with sensory disturbances such as increased sensitivity to experimentally induced pain. This study investigated pain sensitivity in terms of bilateral pressure pain thresholds over the trapezius and tibialis anterior muscles and pain responses after a unilateral hypertonic saline infusion into the ri...

background: more diagnostic techniques require a better understanding of the forces and stresses developed in the wall of the left ventricle. the aim of this study was to differentiate significant coronary artery disease (cad) patients using a non-invasive quantification of myocardial wall stress in the diastole phase. methods: sixty male subjects with sinus rhythm (30 patients with significant...

Purpose: The current study aimed at evaluating the effect of 5-toed shoes on electromyographic activity of leg muscles during the stance phase of running.  Methods: The current semi-experimental study recorded the electromyographic activity of tibialis anterior, soleus, gastrocnemius lateralis, and medialis muscles of 15 healthy male students (mean age: 24.5±3.4 years, mean height:...

Twelve rabbits were cast-immobilized for 4 weeks during which either 10- or 50-Hz stimulation was applied transcutaneously to the anterior compartment muscles. After the treatment period, tibialis anterior and soleus muscle contractile and histochemical properties were measured. Tibialis anterior stimulation at either 10 or 50 Hz had significantly different effects on the ipsilateral, unstimula...

background: joint position sense (jps) is comprised of sensory input from several sources, including skin, joint capsule/ligaments, and muscular receptors. if the muscle receptors play a leading role in detecting joint position awareness, then muscle fatigue might yield a declination in jps. the aim of this study was to evaluate if a sustained fatiguing contraction of the tibialis anterior (ank...
