The supraspinatus muscle plays a key role in shoulder movement and stability, and its structure may be affected in individuals with partial tears.\n\nExercise-based rehabilitation is widely used in the conservative management of these conditions. The full can exercise is commonly prescribed to selectively activate the supraspinatus muscle. However, the effects of different contraction types, specifically concentric and eccentric exercises, on muscle structure and clinical outcomes are not fully understood.\n\nIn this study, participants will be randomly assigned to either a concentric or eccentric full can exercise group. Both groups will receive a standard physiotherapy program, including therapeutic ultrasound and transcutaneous electrical nerve stimulation (TENS), in addition to the assigned exercise protocol.\n\nThe intervention will last for 6 weeks, with sessions performed three times per week. Outcomes will be assessed before and after the intervention.\n\nThe primary outcome is the change in supraspinatus muscle pennation angle measured by ultrasound imaging. Secondary outcomes include muscle architecture parameters, pain intensity, range of motion, muscle strength, functional status, and kinesiophobia.\n\nThe findings of this study may help improve exercise selection in the rehabilitation of individuals with rotator cuff tears.",[28,29,30],"Partial Rotator Cuff Tears","Rotator Cuff Injuries","Shoulder Pain Syndrome",[32,33,34,35,36,37],"Supraspinatus Muscle","Full Can Exercise","Eccentric Exercise","Concentric Exercise","Shoulder Rehabilitation","Muscle Architecture","RECRUITING","2026-08-09",{"date":41,"type":42},"2026-08-11","ACTUAL",{"date":44,"type":22},"2026-07-20",{"date":46,"type":22},"2027-11-20",{"name":48,"class":49},"Firat University","OTHER",1,{"id":52,"slug":53,"hasResults":11,"nctId":54,"briefTitle":55,"officialTitle":56,"acronym":4,"eligibilityCriteria":57,"healthyVolunteers":11,"sex":17,"minAge":18,"maxAge":58,"enrollmentInfo":59,"targetDuration":4,"studyType":23,"phases":61,"briefSummary":62,"conditions":63,"keywords":67,"overallStatus":38,"whyStopped":4,"lastUpdateSubmitDate":78,"lastUpdatePostDateStruct":79,"startDateStruct":81,"completionDateStruct":83,"leadSponsor":85,"locationsCount":50},"100646656","intralesional-versus-perilesional-5-dextrose-injection-in-partial-rotator-cuff-tears-100646656","NCT07688902","Intralesional Versus Perilesional 5% Dextrose Injection in Partial Rotator Cuff Tears","Comparison of Clinical and Ultrasonographic Outcomes of Intralesional and Perilesional 5% Dextrose Injection in Patients With Partial Rotator Cuff Tears: A Prospective Randomized Double-Blind Controlled Trial","Inclusion Criteria:\n\n* Diagnosis of partial rotator cuff tear by a specialist physician after appropriate clinical examination and imaging evaluation\n* Shoulder pain and functional limitation lasting for at least 3 months\n* Clinically confirmed shoulder impingement findings, defined as at least one positive test among Neer, Hawkins-Kennedy, or painful arc tests\n* Age between 18 and 75 years\n* Ability to comply with the study procedures and attend follow-up visits regularly\n* Willingness to participate in the study and provide written informed consent\n\nExclusion Criteria:\n\n* Advanced cognitive impairment or dementia preventing reliable completion of questionnaires\n* Refusal to participate in the study or inability to provide informed consent\n* Full-thickness rotator cuff tear\n* Major tendon pathology other than the supraspinatus tendon, such as full-thickness subscapularis tear or biceps tendon rupture\n* Advanced acromioclavicular joint osteoarthritis, marked impingement, or marked adhesive capsulitis\n* Advanced glenohumeral joint arthritis\n* Active infection, cellulitis, or dermatologic lesion at the injection site\n* Bleeding diathesis or anticoagulant use\n* Known allergy or intolerance to dextrose injection\n* Intra-articular shoulder injection, including steroid, platelet-rich plasma, or prolotherapy, within the last 3 months\n* Previous shoulder surgery\n* Uncontrolled diabetes mellitus, defined as HbA1c \\>8.5%, or severe endocrine or metabolic disorder\n* Immunosuppression or active infection\n* Rheumatologic shoulder involvement\n* Neurological disease affecting shoulder movements\n* Pregnancy\n* Active malignancy","75 Years",{"count":60,"type":22},30,[25],"This prospective, randomized, double-blind controlled clinical trial aims to compare the clinical and ultrasonographic outcomes of intralesional and perilesional 5% dextrose injection in patients with partial rotator cuff tears.
