Eligibility
Inclusion criteria
Inclusion criteria: individuals aged between 18 and 60 years, with shoulder pain for at least three months; at least one positive specific test in physical exam (Jobe test or resisted external rotation); and diagnosed with tendinopathy by an orthopedist through confirmed morphological alterations in the rotator cuff tendons (supraspinatus and/or infraspinatus) observed using nuclear magnetic resonance or ultrasonography
Exclusion criteria
Exclusion criteria: individuals that perform high-intensity sports with high shoulder demand; impaired long head of biceps; adhesive capsulitis; history of glenohumeral luxation or subluxation; history of clavicle, scapula, or humerus fracture; history of rotator cuff surgical intervention; signs of partial or complete rupture of rotator cuff; acromioclavicular joint osteoarthritis; neurologic or rheumatologic dysfunctions; corticoid application at least three months before the baseline evaluation; body mass index>28 kg/m2 since it may compromise quality of electromyography data; and individuals under treatment with fluoroquinolone antibiotics or diabetes because both may affect tendon metabolism.
Design outcomes
Primary
| Measure | Time frame |
|---|---|
| It is expected to find a decrease in pain at rest and during arm elevation with and without load, verified through the numerical pain rating scale, from the observation of 2 points less pain at the end of the treatment, being more evident in the isometric group. | — |
Secondary
| Measure | Time frame |
|---|---|
| It is expected to find improvement in function, verified through the translated version of the Penn Shoulder Score Questionnaire (Penn) and the Western Ontario Rotator Cuff Index (WORC) from the observation of an improvement of 11.4 points on the Penn and a decrease of 245.26 mm in the WORC at the end of the treatment, being more evident in the isometric group.;It is expected to find an increase of 10% in isometric strength for arm elevation and 5% for lateral and medial rotation of the shoulder, verified through the dynamometer (Lafayette Instrument® - model 01165) at the end of treatment, being more evident in the isometric group.;It is expected to find increased electromyographic activity of 0.048, 0.010, 0.096 e 0.070 milliVolts, respectively, for the lower trapezius, infraespinatus, middle deltoid and serratus anterior during arm elevation and isometric lateral and medial shoulder rotations and for the load and unloaded arm elevation motor task, verified through an 8-channel signal conditioning module (MSC 1000) (EMG system do Brasil®) with an analog-digital converter – A/D (CAD, 12/36-60 K) with 12-bit resolution, at the end of the treatment, being more evident in the isometric group. | — |
