About this study
This study will be conducted to investigate the relationship between scapular dyskinesia and rotator cuff muscle strength and acromiohumeral distance in asymptomatic individuals.
Read the detailed description
When the scapula moves in an abnormal way, a condition known as scapular dysfunction (SD) occurs, leading to shoulder pain and dysfunction. It is possible for patients with SD to experience no symptoms at all. SD symptoms can include a combination of the following anterior shoulder pain, Posterosuperior scapular pain, Superior shoulder pain, shoulder impingement syndrome, rotator cuff dysfunction, and shoulder instability.Things like early scapular elevation, abrupt downward rotation, and a prominent medial edge and inferior angle of the scapula are seen during shoulder motions. It has been suggested that impaired scapulothoracic musculature function might lead to changes in shoulder kinematics, which in turn can increase the risk of injury.Individuals with SD often experience pathologies such as scapula-humeral rhythm disturbance, glenoid labrum difficulties, glenohumeral instability, rotator cuff syndrome, subacromial impingement syndrome, and glenoid labrum abnormalities. In individuals suffering from RC tendinopathy, a decline in RC muscle performance is associated with lower health-related quality of life and patient-rated function. In order to determine which patients with scapular dyskinesis may benefit most from a rehabilitation program aimed at enhancing muscular performance, clinicians may find it useful to gather data on shoulder strength. A portable dynamometer is an easy, cheap, and valid way to get these kinds of data. to fill that gap in literature by Finding an association between scapular dyskinesia and the acromiohumeral distance and rotator cuff muscle strength in individuals with asymptomatic scapular dyskinesia

What is being measured
The primary outcome is the main question the study is designed to answer.
subacromial space
The subacromial space will be measured by ultrasonography device with mm or cm. it was defined as the linear perpendicular distance between the top surface of the humeral head and the lower surface of the acromion
Measured: up to one day
Secondary outcomes (3)
shoulder internal rotator muscles strength
shoulder internal rotator muscles strength will be measured by active force 2 device
Measured: up to one day
shoulder external rotator muscles strength
shoulder external rotator muscles strength will be measured by the Active Force 2 device
Measured: up to one day
scapular dyskinesis
lateral scapular slide test (LSST) will be used to assess scapular dyskinesis. examined the distance between the scapular inferior angle and the corresponding spinous process in three different positions using the lateral scapular slide test (LSST) to evaluate scapular stability in both the right and left scapula. The subject's arms were relaxed at his sides, lying on his hips, with his shoulders internally rotated and abducted 45 degrees, and fully internally rotated and abducted 90 degrees.Kibler has stated that a 1.5 cm discrepancy on both sides should be considered abnormal scapular asymmetry.
Measured: up to one day

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 20 May 2026.
