About this study
This study aims to shed light on the supraspinatus and infraspinatus muscles, which play a significant role in rotator sheath tendinopathy and tears. It includes isometric measurements of muscle thickness, fiber length, and pennation angles, as well as muscle strength, using ultrasound to evaluate the muscle architecture of the supraspinatus and infraspinatus muscles in tennis players.
Read the detailed description
The shoulder joint is prone to injury due to its unique anatomy. Rotator cuff lesions (RCL) are a common cause of shoulder pain, with a prevalence of 81% (1). One effective approach for monitoring muscle function is to visualize the architectural structure of the muscle. Muscle architecture is the examination of the structural arrangement of muscle fibers, muscle thickness, pennation angle, and number of sarcomeres according to the force generation axis (2). Ultrasonographic muscle architecture measurements provide a rapid and objective evaluation to examine the pathology of the muscles associated with subacromial impingement syndrome (3).
Muscle strength measurement is a physical performance measurement used to determine the loss of strength in the muscle and to evaluate the effectiveness of the intervention by resisting the muscle (4). It is worth noting that the strength of the rotator cuff muscles, especially the external and internal force-generating muscles of the shoulder, may be somewhat reduced in athletes with RCL. Strength measurement of these muscles can provide valuable data in shoulder evaluation (5). It is also worth mentioning that shoulder injuries are quite common in tennis. In addition to physiotherapy methods, the success rate in RCL treatment may be enhanced by exercise (6). In shoulder rehabilitation, core exercises are designed to help restore functional movements through the elimination of pain and the dynamic stability of the rotator cuff and scapular muscles. The goal is to strengthen the shoulder girdle muscles and achieve sufficient joint range of motion, especially by providing neuromuscular re-education with therapeutic exercises.

The study will include 40 tennis players diagnosed with rotator cuff lesions who meet the inclusion criteria. The 1st group will be randomly divided into 2 groups as control (n=20) and 2nd group as core exercise (n=20).

Questions about this trial
What is this clinical trial studying?
A study testing exercise in people with Exercise and Muscle Weakness, run by Ankara University at 1 site in Turkey (Türkiye).

Who may be eligible to take part?
The sponsor lists 6 inclusion and 5 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 15 Oct 2024. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in Turkey (Türkiye). Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
visual pain scale (time frame: 8 week). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
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 15 Oct 2024; AzTrials last refreshed its copy on 7 Nov 2026.
