intruduction: pattellofemoral pain syndrome (p.f.p.s) is the most common problem in knee joint. various authors have indicated that imbalance of muscle activity between vastus medialis oblique (vmo) and vastus lateralis (vl) might lead to p.f.p.s. the objective is to determine the effect of patellar taping on vmo/vl myoelectric activity ratio during maximal isometric contraction in open and clo...

inhalational insulin was withdrawn from the market due to its potential to produce airway hyper-reactivity and bronchoconstriction. so the present study was designed to explore the acute effects of insulin on airway reactivity of guinea pigs and protective effects of salbutamol and ipratropium against insulin induced airway hyper-responsiveness on isolated tracheal smooth muscle of guinea pig. ...

This study assessed changes in electrical impedance myography (EIM) at different levels of isometric muscle contraction as well as during exhaustive exercise at 60% maximum voluntary contraction (MVC) until task failure. The EIM was performed on the biceps brachii muscle of 19 healthy subjects. The results showed that there was a significant difference between the muscle resistance (R) measured...
