Scapular exercises boost rehab for painful shoulders with dyskinesis

Source: pubmed.ncbi.nlm.nih.gov

TL;DR

Randomized trial tested adding scapular stabilization exercises to standard rehab for patients with subacromial pain syndrome and scapular dyskinesis.
64 patients split into two groups; stabilization group showed better gains in pain reduction, strength, dyskinesis correction, and function after 4 weeks.
Adding these exercises improves rehab outcomes beyond standard mobilization, stretching, and strengthening alone.

The story at a glance

Researchers ran a randomized controlled trial with 64 patients who had subacromial pain syndrome (SPS) and visible scapular dyskinesis. One group got standard rehab plus scapular stabilization exercises; the other got standard rehab only. The study came out in early 2024 as SPS affects 36-48% of shoulder pain cases and often involves dyskinesis that standard care may not fully fix.[[1]](https://www.sciencedirect.com/science/article/pii/S1360859223002139)[[2]](https://pubmed.ncbi.nlm.nih.gov/38432789)

Key points

Patients diagnosed with SPS via clinical signs (Neer's stages) and positive scapular dyskinesis test; all had shoulder pain during movement.
Both groups did 4 weeks of identical standard rehab: glenohumeral/scapular mobilization, pendulum/stretching/ROM exercises, strengthening, proprioception.
Stabilization group added specific scapular exercises targeting muscle activation and coordination.
Post-treatment, stabilization group had significant improvements (p < 0.05) in pain severity, scapular dyskinesis presence, muscle strength, and shoulder disability index.
No group differences (p > 0.05) in shoulder range of motion or scapular upward rotation.
Sample powered for 80% power at alpha 0.05; no baseline differences between groups.

Details and context

Subacromial pain syndrome covers issues like rotator cuff tendinopathy, bursitis, or partial tears, leading to pain on overhead motion and reduced function. Scapular dyskinesis—abnormal scapula movement—often worsens it by narrowing subacromial space and stressing rotator cuff, commonly from poor periscapular muscle timing.

Standard rehab focuses on local shoulder structures, but prior studies mixed on adding scapular work; this trial targeted patients confirmed to have dyskinesis via the scapular dyskinesis test (visual assessment during arm raise). Exercises aimed to restore length-tension in scapular muscles for better glenohumeral rhythm.

Limitations include short 4-week follow-up and no long-term data; full kinematics not measured beyond upward rotation.

Key quotes

"Scapular stabilization exercises added to the shoulder mobilization, stretching, and strengthening are effective in improving scapular dyskinesis, reducing pain, increasing muscle strength and shoulder function in patients with SPS accompanied by scapular dyskinesis."[[1]](https://www.sciencedirect.com/science/article/pii/S1360859223002139)

Why it matters

SPS causes major disability and lost work time, and dyskinesis is common but often overlooked in basic rehab. Clinicians can use these findings to target scapular control in confirmed cases, potentially cutting pain and boosting strength faster without extra tools. Watch for replication trials with longer follow-up or imaging to confirm kinematic changes.
