background and objectives: scapular stabilization and neuromuscular control provide an important parameter to characterize shoulder function during dynamic activities. many studies have confirmed the effect of the loading on scapular position and scapulohumeral rhythm. therefore, the evaluation of stabilizer muscles involvement in scapular asymmetry may assist in the development of clinical exa...

Purpose: Muscle activation of the proximal parts is necessary for distal activities. In fact, proximal muscles provide stabilized and controlled base for distal parts activities. The purpose of this systematic review was to determine whether hand grip task can alert the activation of shoulder girdle muscles. Methods: A literature search was done in PubMed, Scopus, Elsevier, Ovid, CINAHL, S...

[Purpose] The purposes of this study were: 1) describe a hierarchy of electromyographic activity production, using percentage maximum voluntary contraction of lumbar iliocostalis and lumbar multifidus muscles during prone, quadruped and sitting exercises; and 2) identify optimal recruitment exercises for both lumbar iliocostalis as a global multi-segmental stabilizer and lumbar multifidus as a ...

abstract objectives: the purpose of this study was to investigate the relationship between core stability and lower extremity injuries in female athletes through functional tests. decreased core stability has been suggested to contribute to the etiology of lower extremity injuries. so far researches had been used non-functional tests to assess the core stability. material and methods: fifty col...

The purpose of this study is to determine if scapular stabilizer weakness and instability is a plausible explanation for excessive winging and/or tipping of the scapula in females who participate in overhead sports. Instability may be an early sign of weakness that can contribute to shoulder injury. Literature regarding causes of scapular winging and tipping pertaining to weak scapular stabiliz...
