Glenohumeral Internal Rotation Deficit Clinical Trial
Official title:
Comparing the Effects of Pelvic Alignment and Diaphragmatic Breathing on Glenohumeral Internal Rotation Deficit (GIRD) - A Randomized Control Trial
The goal of this research study is to compare the effects of pelvic alignment versus diaphragmatic breathing on range of motion in the shoulder joint in both athletic and nonathletic population. The investigators plan to have approximately 45 participants to take part in this study. Subjects will be assigned into three groups. Group 1 will perform both pelvic alignment and diaphragmatic breathing exercises. This group will be used as the standard or control group. Group 2 will perform pelvic alignment exercise only; and Group 3 will perform diaphragmatic exercises only. The shoulder internal rotation range will be assessed in all three groups. Maximal expiratory rate will be measured in group 3 to assure improved diaphragmatic breathing in subjects. The shoulder internal rotation range in group 2 & 3 will be compared to the shoulder range of motion in the standard group.

Primary | Changes in shoulder internal rotation rang of motion | A Cybex isokinetic table will be used for standard positioning of the participants's arm. the participant will be positioned in supine, with his/her arm supported on the dynamometer's arm for shoulder assessment. Shoulder internal rotation range of motion will be assessed using the digital goniometer incorporated into the cybex dynamometer. | Change from baseline internal rotation range of motion after 5 days of intervention | |
Primary | Changes in Maximal expiratory rate | A digital spirometer (EasyOne Plus Diagnostic Spirometry System) will be use for assessing maximal expiratory rate. A maximal expiratory test will be performed with the subject in sitting. A nose clip will be used to ensure all air is going into the manometer. Our measurements will be taken from total lung capacity, so the subject will first fully inhale, then fully exhale, pausing for 1-2 seconds at the end. | Change from baseline expiratory rate after 5 days of intervention | |
Secondary | Change in pelvic alignment | Ober's test will be used to assess pelvic alignment. Limited hip joint adduction range of motion is considered as a positive test. | Change from baseline hip adduction range of motion after 5 days of interventjion |
