What Is Shoulder Impingement?
Shoulder impingement syndrome occurs when the soft tissues in the subacromial space. The rotator cuff tendons and subacromial bursa — are compressed or "impinged" between the humeral head and the acromion during shoulder elevation.
It is the most common cause of shoulder pain, accounting for 44–65% of all shoulder complaints. In Faridabad, shoulder impingement is frequently seen in cricketers, office workers with poor posture, overhead labourers, and swimmers.
Research: A 2019 Cochrane review (Steuri et al.) found that exercise therapy produces clinically meaningful improvements in pain and function for subacromial impingement, with outcomes equivalent to surgical subacromial decompression at 6 months and 2 years — establishing physiotherapy as the evidence-based first-line treatment.
Types of Shoulder Impingement
- External (subacromial) impingement: Compression of the supraspinatus tendon and bursa between the acromion above and humeral head below. The most common type.
- Internal impingement: Contact between the posterior rotator cuff and the glenoid rim in extreme external rotation and abduction — typically in overhead throwers like cricket bowlers.
- Primary impingement: Structural narrowing of the subacromial space due to bony spur, os acromiale, or Type III acromion.
- Secondary impingement: Functional narrowing due to poor muscle control (scapular dyskinesis, weak rotator cuff) — far more common and highly responsive to physiotherapy.
Causes and Contributing Factors
- Poor scapular mechanics (scapular dyskinesis) — the most common driver
- Weak rotator cuff muscles, particularly supraspinatus and external rotators
- Tight posterior shoulder capsule causing humeral head to ride forward and up
- Rounded shoulders and thoracic kyphosis from prolonged desk work
- Repetitive overhead activities: cricket, badminton, swimming, painting, construction
Symptoms
- Painful arc — shoulder pain during elevation between 60–120°
- Anterior or lateral shoulder pain, often radiating to the mid-arm
- Pain with reaching overhead, behind the back, or across the body
- Night pain and difficulty sleeping on the affected shoulder
- Positive Neer impingement sign and Hawkins-Kennedy test
Shoulder Impingement Treatment at Realign Clinic Faridabad
Shoulder impingement is one condition where I see dramatic improvements with the right physiotherapy programme. Most patients have secondary impingement driven by poor scapular control and weak rotator cuff — structural problems are actually rare.
We address the thoracic spine (thoracic extension mobilisation is often the missing piece), then progressively load the rotator cuff and lower trapezius. The combination resolves impingement in the vast majority of patients without surgery or injections.
Shoulder Impingement Evidence
- ✦ Exercise therapy = surgical decompression at 2-year follow-up (Cochrane 2019)
- ✦ 12–16 weeks of physiotherapy resolves impingement in 70–80% of patients
- ✦ Scapular control training adds 30% improvement over rotator cuff exercises alone
- ✦ Corticosteroid injection provides short-term relief but 60% recurrence without exercise (Cochrane 2017)
Scapular Control Training
Scapular setting exercises, wall slides, serratus anterior activation, lower trapezius exercises (prone Y/T/W). Proper scapular upward rotation creates space in the subacromial region and is the most effective long-term treatment for secondary impingement.
Rotator Cuff Strengthening
External rotation, internal rotation, and supraspinatus exercises (full can) with resistance bands. Progressive loading over 10–16 weeks.
External rotation strength is often severely deficient in impingement patients and is critical for humeral head depression (preventing upward migration during elevation).
Posterior Capsule Stretching
The sleeper stretch and cross-body stretch for the posterior shoulder capsule. A tight posterior capsule is extremely common and causes the humeral head to migrate anterosuperiorly — directly narrowing the subacromial space. 3 × 30 second holds, twice daily.
Thoracic Extension Mobilisation
Thoracic spine manual therapy and self-mobilisation (thoracic extension over a foam roller) improves the coupling between shoulder and thoracic motion. Poor thoracic mobility is a frequently overlooked driver of shoulder impingement, particularly in office workers in Faridabad with desk-related thoracic kyphosis.
Home Exercises for Shoulder Impingement
Sleeper Stretch
Lie on your affected side, arm at shoulder height with elbow at 90°. Gently press the wrist downward toward the floor with the opposite hand.
Hold 30 seconds, 3 repetitions. Stretches the posterior shoulder capsule — one of the most important exercises for subacromial impingement.
Scapular Wall Slides
Stand with back and hands against a wall. Slide arms upward maintaining contact, keeping elbows slightly bent.
Stop when pain begins. 3 sets of 10. Trains scapular upward rotation — fundamental to impingement resolution.
Frequently Asked Questions — Shoulder Impingement
Q: Does shoulder impingement require surgery?
In the majority of cases, no. Multiple high-quality RCTs and Cochrane reviews have found physiotherapy produces equivalent outcomes to arthroscopic subacromial decompression.
Surgery is reserved for rare cases with a structural cause (bony spur, os acromiale) that fail complete physiotherapy over 6 months. At Realign Clinic Faridabad, we expect to resolve most impingement cases conservatively.
Q: How long does shoulder impingement take to resolve?
Most patients experience meaningful improvement within 6–8 weeks of focused physiotherapy. Full resolution typically takes 12–16 weeks.
Chronic cases (more than 1 year) may take 4–6 months. Key factors: thoracic mobility, consistency with the home exercise programme, and avoiding aggravating activities during recovery.
Q: Can I swim or play cricket with shoulder impingement?
Cricket: overhead bowling should be avoided during acute phases. Batting and fielding can continue with modification.
Swimming: freestyle stroke significantly loads the subacromial space — breaststroke is better tolerated. We design sport-specific modifications so you can continue training while rehabilitating the shoulder.
