BACKGROUND AND PURPOSE Several factors such as posture, muscle force, range of motion, and scapular dysfunction are commonly believed to contribute to shoulder impingement. The purpose of this study was to compare 3-dimensional scapular kinematics, shoulder range of motion, shoulder muscle force, and posture in subjects with and without primary shoulder impingement syndrome. SUBJECTS Forty-fi...

Background: Shoulder pain is prominent among sedentary employees who make motions of the upper limbs on a regular basis. Rounded shoulder posture (RSP) and hunched (HSP) are most common clinical postural misalignments. These causes spine to bend raise tension nerve roots, which has negative impact upper-extremity muscular strength function. Therefore, this study was carried out investigate effe...

STUDY DESIGN Repeated-measures design comparing 7 static weight-bearing shoulder exercises. OBJECTIVE The purpose of this study was to determine the demand on shoulder musculature during weight-bearing exercises and the relationship between increasing weight-bearing posture and shoulder muscle activation. BACKGROUND Weight-bearing shoulder exercises are commonly prescribed in the rehabilita...

OBJECTIVE We investigated how multi-joint changes in static upper limb posture impact the corticomotor excitability of the posterior deltoid (PD) and biceps brachii (BIC), and evaluated whether postural variations in excitability related directly to changes in target muscle length. METHODS The amplitude of individual motor evoked potentials (MEPs) was evaluated in each of thirteen different s...

The aim of the research was to establish whether the children between the ages of 7 and 10 years, attending Grades 1–4 of music oriented and general education classes, suffered from posture defects. The research material included 214 children aged 7–11 of the Primary School Complex no. 2 in Szczecin. There were 101 children examined in the music oriented classes, including 51 (50.5%) girls and ...

OBJECTIVE To assess head posture using cervical spine X-rays to find out whether forward head posture is related to myofascial pain syndrome (MPS) in neck and shoulder. METHODS Eighty-eight participants who were diagnosed with MPS in neck and shoulder were evaluated in this study. Four parameters (distance among head, cervical spines, and shoulder, and cervical angle) were measured from later...

QUESTION Is neck/shoulder pain in adolescents related to their sitting spinal posture, taking account of gender? DESIGN Cross-sectional survey and direct observation. PARTICIPANTS 1597 adolescents from the 'Raine' birth cohort study (781 females, 816 males) with a mean age of 14.1 years (SD 0.2). OUTCOME MEASURES Neck/shoulder pain prevalence and gender was measured by survey. Spinal post...
