Study Details

Study Description

Brief Summary

Shoulder pain accounts for approximately 16% of all musculoskeletal symptoms. Rotator cuff tendinopathy is the most common cause of shoulder pain.

The aim of this study is to compare the effects of ultrasound-guided subacromial ozone (O2-O3) versus corticosteroid injection in patients with chronic rotator cuff tendinopathy.

Detailed Description

Shoulder pain accounts for approximately 16% of all musculoskeletal symptoms. Rotator cuff tendinopathy is the most common cause of shoulder pain.

There are limited studies comparing the efficacy of ozone and corticosteroid injections in rotator cuff tendinopathy. In this context, the aim of this study is to compare the effects of ultrasound-guided subacromial ozone (O2-O3) versus corticosteroid injection in patients with chronic rotator cuff tendinopathy.

Arms and Interventions

Arm Intervention/Treatment
Active Comparator: Ozone (O2-O3) group

Ultrasound (US)-guided injections will be performed with a 5-12 MHz linear transducer (Logic e portable; GE Healthcare, China) by the same physiatrist and injections will be administered into the subacromial bursa with a posterolateral approach. 3 sessions (1 session/week) of 5 mL of ozone (O2-O3) will be injected (with a concentration of 10 μg/mL in the first session, 15 μg/mL in the second session, and 20 μg/mL in the third session).

Procedure: Ozone (O2-O3) injection
US-guided injections will be performed with a 5-12 MHz linear transducer (Logic e portable; GE Healthcare, China) by the same physiatrist and injections will be administered into the subacromial bursa with a posterolateral approach. 3 sessions (1 session/week) of 5 mL of ozone (O2-O3) will be injected (with a concentration of 10 μg/mL in the first session, 15 μg/mL in the second session, and 20 μg/mL in the third session).

Other: Corticosteroid group

US-guided injection will be performed with a 5-12 MHz linear transducer (Logic e portable; GE Healthcare, China) by the same physiatrist and injections will be administered into the subacromial bursa with a posterolateral approach. A mixture of 1 mL corticosteroid (betamethasone 3 mg/mL) and 1 mL lidocaine (20 mg) will be injected (1 session).

Procedure: Corticosteroid injection
US-guided injections will be performed with a 5-12 MHz linear transducer (Logic e portable; GE Healthcare, China) by the same physiatrist and injections will be administered into the subacromial bursa with a posterolateral approach. A mixture of 1 mL corticosteroid (betamethasone 3 mg/mL) and 1 mL lidocaine (20 mg) will be injected (1 session).

Outcome Measures

Primary Outcome Measures

  1. The Western Ontario Rotator Cuff Index (WORC) [at baseline and change from baseline WORC at 4 weeks and 12 weeks after injections]

    The Western Ontario Rotator Cuff Index (WORC) is a self-administered assessment tool for rotator cuff disease. WORC has 21 questions in 5 domains consisting of work, physical symptoms, social well-being, emotional well-being, and sports and recreation. Each question is scored on a 100-mm, with higher scores demonstrating larger problems. Turkish validity of the WORC has been illustrated.

Secondary Outcome Measures

  1. The Shoulder Pain and Disability Index (SPADI) [at baseline and change from baseline SPADI at 4 weeks and 12 weeks after injections]

    The Shoulder Pain and Disability Index (SPADI) is a 13 item self-assessment measurement tool to evaluate disability (8 items) and pain (5 items). The subscales of disability and pain are measured as the average of the corresponding items between 0-100, with higher scores indicating greater disability and pain.

  2. Visual Analogue Scale (VAS) [at baseline and change from baseline VAS at 4 weeks and 12 weeks after injections]

    The severity of the patients' shoulder pain in the last week will be evaluated using the 10-point VAS (from 0 (no pain) to 10 (worst imaginable pain))

Other Outcome Measures

  1. Ultrasonographic measurements [at baseline and change from baseline ultrasonographic measurements at 4 weeks and 12 weeks after injections]

    supraspinatus tendon thickness, subacromial bursa thickness and acromiohumeral distance will be measured by US in both groups
