Abstract

Background

Shoulder conditions are caused by trauma or injury, fracture, instability, shoulder subluxation, upper cross syndrome, trapezitis, rounded shoulder, degenerative changes, adhesion formation etc. The purpose of the study was to observe the prevalence of the pectoralis minor muscle shortening on shoulder conditions.

Objective

The study was to analyze the prevalence of pectoralis minor muscle shortening in pathological shoulder conditions and also to compare the shortening of pectoralis minor muscle among patients with shoulder conditions.

Methodology

The study was an observational study with 60 subjects between the ages of 45–60 years. The study was conducted in outpatient of physiotherapy department in A.C.S medical college and hospital. Both genders were included in this study.

Result

The result reported that the pectoralis minor muscle shortening is more on adhesive capsulitis with mean value of 6.02, than other conditions of rounded shoulder, upper cross syndrome, trapezitis, fracture, shoulder subluxation with mean value of 6.49, 7.17, 6.94, 7.04, and 6.94 respectively.

Conclusion

Pectoralis minor muscle shortening found significant change on adhesive capsulitis when compare with upper cross syndrome, rounded shoulder, fracture, trapezitis and shoulder subluxation with F value 4.958 and p<0.001.
