Background: Shoulder muscle timing is very important, however, study on the shoulder muscle timing and recruitment patterns is limited. Thus, the aim of the study was to determine and compare the timing and recruitment order of the shoulder muscles in subjects with and without Shoulder Impingement Syndrome (SIS). Methods: In this case-control study, 9 female subjects with shoulder impingement s...

The effect of some anthropometric factors and loading on paravertebral muscles was tested in this study. Thirty two healthy men with mean age of 25.25 years participated in this study. They didn't have history of low back pain since 12 months ago. The effect of weight, height, upper limb length, abdominal & chest circumference and upper body height and other factors e.g. body mass and functiona...

Background and Objective: Several studies have reported significant disturbances in vertical posture during various standing and walking conditions, but there is little evidence about the behavior of related muscles in dynamic conditions such as external perturbation, so this study was done to investigate and to compare the delay in response of upper trapezius and sternocleidomastoid muscles as...

Objective: Limitation of ankle dorsiflexion range of motion as the most important risk factors for ankle sprain injury can cause disorder in neuromuscular control of muscles around the ankle. The aim of this study was to compare the onset of the activity of selected muscles around the ankle joint of those athletes with ankle dorsiflexion range of motion limitations with healthy Athletes during ...

Purpose: The body core facilitates the transition of forces and moments between the upper and lower extremities in every movement. The present study investigated the differences in the sonographic activity of the deep lumbopelvic muscles during the implementation of plank movements on stable and unstable surfaces. Methods: In total, 16 female athletes with the Mean±SD age of 23.69±3.57 years, ...
