Brief Summary

The goal of this study is to diagnose scapular dyskinesis-which can appear as a cause or result of various shoulder disorders-through screening tests in patients with shoulder impingement syndrome, the most common shoulder condition. By identifying scapular dyskinesis, the study aims to maximize treatment outcomes through appropriate rehabilitative exercise therapy.

Conditions

Scapular Dyskinesis; Impingement Syndrome, Shoulder

Outcome Measures

Primary Outcomes (1)

  Initial, 3, 7, 13 weeks

Secondary Outcomes (2)

• American Shoulder and Elbow Surgeons' (ASES) score

  Initial, 3, 7,13 weeks

Study Arms (2)

Impinge c SD treatment

EXPERIMENTAL

In this experimental group, rehabilitation for scapular dyskinesis will begin at the second outpatient visit, which takes place three weeks after the subacromial steroid injection.

Behavioral: SD rehabilitation

Impinge s SD treatment

SHAM COMPARATOR

In this sham group, rehabilitation for scapular dyskinesis will not be begun at the second outpatient visit, which takes place three weeks after the subacromial steroid injection.

Behavioral: No SD rehabilitation

Interventions

SD rehabilitation BEHAVIORAL

For shoulder impingement syndrome, the standard rehabilitation protocol involves administering a subacromial steroid injection at the initial outpatient visit, followed by stick exercises to restore joint mobility starting three weeks later. Four weeks after initiating the stick exercises, rotator cuff strengthening exercises using therabands are introduced and maintained for a duration of six weeks. For SD rehabilitation, shoulder external rotation, push up plus, and shoulder rolls were performed. In the experimental group, rehabilitation for scapular dyskinesis will begin at the second outpatient visit, which takes place three weeks after the subacromial steroid injection.

Study Design

• Study Type: interventional
• Phase: not applicable
• Allocation: RANDOMIZED
• Masking: TRIPLE
• Who Masked: PARTICIPANT, CARE PROVIDER, OUTCOMES ASSESSOR
• Masking Details: The investigators plan to enroll patients who consent to participate in the study and allocate them into two groups using a random sequence generator. A random allocation table will be created and managed by a third party who is not involved in the study. When planning the treatment method, group assignment will be requested from this third party holding the allocation table, ensuring that the allocator is blinded to the upcoming group assignments in advance. Treatment in each group will be administered consistently according to a pre-agreed protocol, and follow-up will also be conducted using the same method in both groups.

Model Details: This study involves patients who visited the outpatient clinic with unilateral shoulder pain persisting for more than three months and were diagnosed with unilateral shoulder impingement syndrome based on MRI findings. Only patients who provided informed consent were enrolled in the study. A total of 320 patients with unilateral shoulder impingement syndrome from Chuncheon Sacred Heart Hospital were included. The participants were randomly assigned into two groups of 160 patients each. Both groups underwent rehabilitation for shoulder impingement syndrome; however, the control group (Group 1) did not receive rehabilitation for scapular dyskinesis, while the experimental group (Group 2) did receive rehabilitation targeting scapular dyskinesis.
