All baseline measurements will be collected in the beginning. In participant of experimental group the K-tape will be first applied from the anterior aspect of the acromion process of the scapular to the spinous process of the fourth thoracic vertebra (T4). Then, the K-tape will be applied from same origin to the insertion at the spinous process of the tenth thoracic vertebra (T10). K-tape will be applied with 50% tension of its original length.

The K-tapes will be replaced with new ones every two days for six weeks. The outcome measures will be assessed after every two weeks i.e. pre-assessment, on week 2, week 4, and week 6.

Primary outcome measures include the effect of kinesio taping on pulmonary function (via Digital Spirometry) and chest expansion (via Measuring Tape).Secondary outcome measures include FSP and pectoralis minor index (via Digital Vernier Caliper)

Stretching exercise for Pectoralis Minor and Major muscle: Participant in supine lying try to touch the tip of shoulder with the bed surface e.g. retraction. Than in supine raise/abduct the arm at 90 and 120 degrees; try to drop down from the surface of the bed. Hold for 10 seconds 10 reps. 2 sessions per day for 6 weeks.

Strengthening of Rhomboids: Participant in sitting position instructed to depress and retract the shoulder at the same time .Hold for 20 seconds 10 reps. 2 sessions per day for 6 weeks.

Strengthening of lower and mid trapezius: In prone lying abduct arms to the side 90 degrees. Raise arms form surface of bed like an aero plane wings. Take a weight of 1 kg in hands and hold for 10 sec and 10 reps. 2 sessions per day for 6 weeks.

Deep Breathing exercise: participant instructed to take a slow and deep breath inhaling through nose and exhaling through mouth. 10 rep 3 sessions per day for 6 weeks.

Education regarding posture correction.

Kinesio Taping will be applied for 6 weeks and it will be changed with new one after every two days

Peak expiratory flow rate (PEFR) Peak expiratory flow rate (PEFR) measured through digital spirometer. Peak Expiratory Flow Rate (PEFR) measured through digital spirometer. Three zones of measurement are commonly used to interpret peak flow rates. Normal value of PEFR is (80-100%). Green zone indicates 80 to 100 percent of the usual or normal peak flow reading, yellow zone indicates 50 to 79 percent of the usual or normal peak flow readings, and red zone indicates less than 50 percent of the usual or normal peak flow readings

Forced vital capacity (FVC) measured through digital spirometer. If the value of FVC is within 80% of the reference value, the results are considered normal.

Changes in FVC from baseline to 5th and after 15th day of intervention will be assessed.

Forced expiratory volume in 1sec (FEV1) measured through digital spirometer. If the value of FEV1 is within 80% of the reference value, the results are considered normal.

Chest expansion is the difference in thoracic girth after maximum inspiration and maximum expiration, which is one indicator of chest wall mobility. As it is measured using a measuring tape, it is a simple, inexpensive, and noninvasive tool for assessing chest mobility.

The forward shoulder posture (FSP) is characterized by downward rotation and anterior tilt of the scapula

Pectoralis Minor Index (PMI) is a proposed parameter to evaluate the pectoralis minor length (PML), eliminating the effect of subject's variability of height.
