A comparative study on scapular static position between femaleswith and without generalized joint hyper mobility

Generalized joint hyper mobility predisposes some individuals to a wide variety of musculoskeletal complaints. Given the critical role of scapular position in function of shoulder, the aim of this study was to compare scapular position between persons with and without general joint hyper mobility. By nonprobability sampling 30 hyper mobile persons at average of 22.86 ±2.77 years of age and 30 non hyper mobile persons (age 23.6 ± 2.73years) through a case-control design participated in the study. Scapular position was assessed according to the lateral scapular slide test. Independent t test and repeated measures ANOVA were used to statistically analyze scapular position differences between groups. Compared to non hyper mobile persons, those with General joint hyper mobility demonstrated a significantly higher superior scapula slide in dependent arm position (p=0.03). However, no significant difference was found between another scores between two groups (p>0.05). The results suggest that altered scapular position may be an important aspect of General joint hyper mobility.
