Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
Subject selection, randomization, and blinding process: Using statistical power analysis 45 healthy, college aged participants are needed for this study. These subjects will be volunteers and recruited by word of mouth by campus professors, coaches and physical therapy students and faculty.
Intervention timeline: Baseline assessment (pretest), five treatment sessions and a posttest. The time required by subjects will be between five and seven days total with each immediately succeeding the next. Treatment sessions will be approximately 10 minutes each. If any portion of this timeline happens to fall outside of the university operational hours, then the intervention will resume the following day. Subjects will be informed of their rights to receive the results of their assessments following the conclusion of the study. Two of the investigators will perform the initial screenings, groups assignments and treatments for all subjects. The other two investigators, who are blinded on participant's group assignment will perform all pretest and posttest measurements. Intraclass Correlation Coefficient model (3,3) will be used, in a pilot study, to assess inter-rater and intra-rater reliability for all testing procedures.
Testing Procedures:
The primary measurements include Ober's test, assessment of shoulder internal rotation range of motion, and spirometry measurements of maximal expiratory rate.
Range of motion assessment: A Cybex isokinetic table will be used to measure passive shoulder internal rotation range of motion. The Cybex will provide standardized arm position and accurate digital measurement of the shoulder internal rotation bilaterally. All pretest and posttest ROM measurements will be performed by the same examiners.
Pelvic alignment assessment: Ober's test will be used to assess pelvic alignment. Although this test is widely known as an assessment of iliotibial band/fascia lata length, it was originally used to assess pelvic alignment. It has been suggested that a unilateral positive Ober's test is indicative of hemipelvic anterior tilt and forward rotation, which leads to a bony block of the rim of the acetabulum on the femoral neck. This bony block would decrease the amount of adduction, leading to a positive Ober's test.
Craig's test will be used during the screening process to assess presence of excessive femoral anteversion angle.
Spirometry: A digital spirometer is used for measuring maximal expiratory rate.
Treatment Procedures:
Neuromuscular Exercise for combined Pelvic Alignment and Diaphragmatic Breathing:
Pelvic alignment and diaphragmatic breathing exercise included simultaneous activation of the hamstring, hip adductor and transverse abdominal muscles with forceful exhalation.
Pelvic Alignment Exercises: Pelvic alignment involves simultaneous activation of the hamstring muscles and hip adductors to reset pelvic symmetry.
Diaphragmatic Breathing exercise: Diaphragmatic breathing involves subject education for simultaneous rise of chest and abdominal wall with inhalation.

Study Groups

Pelvic alignment and forceful expiration exercise
Pelvic alignment and forceful expiration
The participant will be in supine with feet flat on a wall and the knees and hips flexed to 90 degrees. A standard 5" ball will be placed between the knees. The participant will hold a standard 9-inch balloon in the mouth with one hand. The subject will be instructed to isometrically contract the hamstrings to lift the ischium off the table while maintaining a posterior pelvic tilt. In this position, subject will be instructed to perform isometric hip adduction by squeezing the ball placed between the knees. The subject will then be instructed to breathe in through the nose and blow the air out into the balloon with full exhalation to activate the transverse and oblique abdominals. The participant will hold the breath for 3 seconds while maintaining hamstring contraction, adductor contraction, and transverse and oblique abdominal contraction. This process will be repeated four times. This exercise will be performed once daily under the supervision of the therapist for 5 days.
Pelvic repositioning exercise
Pelvic repositioning exercise
The participant will be positioned supine with their feet flat on a wall and the knees and hips flexed to 90 degrees. The subject will be instructed to isometrically contract the hamstrings to allow the ischial tuberosities to lift off the table while also maintaining a posterior pelvic tilt. The tailbone should be slightly lifted off the table, the abdominal muscles should be relaxed, and the low back should be flat on the table. While maintaining the posterior pelvic tilt, the subject will be instructed to perform isometric hip adduction by squeezing the ball that is placed between the knees. The subject will hold for 3 seconds and then relax. This process will be repeated four times. This exercise will be performed daily under the supervision of the therapist for 5 days.
Diaphragmatic breathing exercise
Diaphragmatic breathing exercise
For diaphragmatic breathing exercise, the subject will be in supine position. The investigator places both hands around the participant's lower ribs and abdominal area. The investigator applies slight manual resistance to the chest and abdominal wall during inhalation phase of breathing.The participant is instructed to apply outward pressure against the investigator resistance and to raise the chest and abdominal wall simultaneously with inhalation. Then participants performs a full exhalation and hold his/her breath for 3 seconds before breathing in again. This process is repeated for 4 breathing cycles. Participants will perform this exercise once a day under investigator supervision.
