The aim of this study was to investigate effects of mop handle height on electromyographic (EMG) activities of the shoulder muscles and perceived exertion for the shoulder area during floor mopping using a figure eight method. An experimental study with 13 cleaners was conducted using surface EMG and category ratio (CR-10) scale. EMG activity was recorded unilaterally from the upper trapezius, ...

Upper extremity reconstruction is most often encountered in trauma patients. Although the rate of complications from elective orthopedic procedures remains relatively low, these complications are oftentimes in the form of open joints or joint infections that can be devastating. Classically, wounds of the shoulder girdle have been treated with large muscles such as the pectoralis major, pectoral...

It is believed that a strong core will enable an athlete to effectively transfer forces from the lower extremities through torso upper extremities. Control of shoulder girdle force important for proper function extremities, although stabilising trunk and pelvis are also important. The purpose this study determine association between isometric push-up/pull-down strength abdominal muscles. Using ...

The subclavian-axillary arterial tree is responsible for the arterial supply to the rotator cuff muscles as well as other shoulder muscles. This study comprised the bilateral dissection of the shoulder and upper arm region in thirty-one adult and nineteen fetal cadaveric specimens. The variable origins and branching patterns of the axillary, subscapular, circumflex scapular, thoracodorsal, post...

Neural coupling of proximal and distal upper limb segments may have functional implications in the recovery of hemiparesis after stroke. The goal of the present study was to investigate whether the stretch reflex response magnitude of spastic finger flexor muscles poststroke is influenced by sensory input from the shoulder and the elbow and whether reflex coupling of muscles throughout the uppe...

Aims: Over exercise is the most frequent cause of chronic shoulder pain and rotator cuff muscles chronic tendonitis is the most frequent problem among professional athletes. The purpose of this study was to review the effect of a period of compound treatment (physiotherapy, massage therapy, PNF stretching exercises) on rotator cuff muscles chronic tendonitis in Professional athletes. Materials ...

Stiffness properties of the musculo-skeletal system can be controlled by regulating muscle activation and neural feedback gain. To understand the regulation of multijoint stiffness, we examined the relationship between human arm joint stiffness and muscle activation during static force control in the horizontal plane by means of surface electromyographic (EMG) studies. Subjects were asked to pr...

[Purpose] This study investigated the differences in shoulder muscles activities during shoulder abduction between a forward shoulder posture group and asymptomatic group. [Subjects] Seven males with forward shoulder posture (FHS) and seven asymptomatic males were recruited. [Methods] We measured the upper and middle trapezius (UT and MT), serratus anterior (SA), and clavicle portion of the pec...
