About this study
Official title: Comparative Effects of Closed Kinetic Chain Exercises and Thrower's Ten Exercises on Pain, Mobility and Performacne in Glenohumeral Instability Among Bowlers
The study is randomized and single-blinded. Ethical approval is taken from ethical committee of Riphah International University, Lahore. Participants who meet the inclusion criteria will be enrolled and allocated in group A \& B through sealed envelope method by Non-probability Convenient random sampling technique. Subjects in Group A will receive closed kinetic chain exercises. Group B will receive thrower's ten exercises.
Read the detailed description
This study will be a randomized clinical trial duration of study will be 10 months.
Data will be collected by convenient sampling technique from Pakistan cricket board. Three outcome measures will be compared by using different tools pain is measured by NPRS, mobility is measured by goniometer and performance is measured by upper limb rotation test .pre and post assessment is done Participants are divided into two groups group A undergoes closed kinetic chain exercise , group B undergoes throwers ten exercise observed values will be analyzed by using SPSS 27 software

What is being measured
The primary outcome is the main question the study is designed to answer.
Pain measure through NPRS
Pain measure through NPRS, The NPRS scoring system is a widely used tool in healthcare for assessing pain intensity. It typically uses a scale from 0 to 10, where 0 indicates no pain and 10 represents the worst possible pain.
Measured: Pre and 6 week post interventional
Mobility measure through Goniometry
Mobility measure through Goniometry, Goniometry measures glenohumeral (shoulder) mobility by placing a goniometer axis on the humeral head or acromion process to score active and passive range of motion degrees. Normal adult values typically reach 170°-180° for flexion and abduction, 70°-90° for internal rotation, and 90°-100° for external rotation
Measured: Pre and 6 week post interventional
performance measure through upper limb rotation test
performance measure through upper limb rotation test, The Upper Limb Rotation Test (ULRT) for the glenohumeral joint is scored by counting the total number of valid repetitions (touches) achieved across three 15-second trials. The final score is the average or sum of valid touches per side, reflecting shoulder stability, dynamic control, and trunk rotation coordination
Measured: Pre and 6 week post interventional
