Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

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

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
Experimental: closed chain kinetic exercises
The group participated in 6 weeks of training session lasting for 45-50 minutes.The individual was positioned standing with the elbow joint completely extended, palm on the wall, and shoulder flexion at a 90° angle
Other: closed kinetic chain exercises
The group participated in 6 weeks of training session lasting for 45-50 minutes.The individual was positioned standing with the elbow joint completely extended, palm on the wall, and shoulder flexion at a 90° angle
Experimental: Thrower's ten exercises
Throwers ten exercise are used to improve strength and endurance of rotator cuff muscles and scapular stabilizers, pre and post assessment is done as my study will be randomized clinical trial , 5-10 minutes of warm up , 45 minutes of resistance training and 5-10 minutes of cool down is added.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Pain measure through NPRS
Time Frame: Pre and 6 week post interventional
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.
Pre and 6 week post interventional
Mobility measure through Goniometry
Time Frame: Pre and 6 week post interventional
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
Pre and 6 week post interventional
performance measure through upper limb rotation test
Time Frame: Pre and 6 week post interventional
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
Pre and 6 week post interventional
