Shoulder Bursitis and Impingement Physiotherapy in West Perth
Shoulder bursitis rarely exists in isolation. The inflamed bursa is usually a symptom of a shoulder that isn't moving properly — and treating the bursa without addressing what's causing the problem is why so many people find it keeps coming back. At PhysioLogix we assess the whole shoulder system and treat what's actually driving it.
What is Shoulder Bursitis?
The subacromial bursa is a fluid-filled sac that sits between the rotator cuff tendons and the underside of the acromion — the bony arch at the top of the shoulder. Its job is to reduce friction between these structures during shoulder movement. When the mechanics of the shoulder are disrupted — through weakness, muscle imbalance, or restricted movement — the bursa gets compressed and irritated repeatedly, leading to inflammation and pain.
This is why the modern understanding of shoulder bursitis is closely linked to shoulder impingement syndrome. In most cases they are the same problem viewed from two angles: the bursa becomes inflamed because the shoulder is impinging — compressing the subacromial space — and the impingement is driven by the underlying mechanical factors.
Shoulder Bursitis vs Rotator Cuff Tear vs Impingement — What's the Difference?
These three conditions are closely related and frequently confused — and distinguishing between them matters because the treatment approach differs.
Shoulder bursitis — inflammation of the subacromial bursa, typically caused by compression of the subacromial space. Pain is usually at the front or side of the shoulder, worse with overhead movements and activities that compress the shoulder such as lying on it. The rotator cuff tendons are not torn but the space they move through is compromised.
Shoulder impingement syndrome — the broader term for compression of the subacromial space. Bursitis is often a component of impingement. The two are frequently used interchangeably and in practice represent the same underlying mechanical problem.
Rotator cuff tear — actual tearing of one or more of the four rotator cuff muscles. This produces weakness alongside pain and is diagnosed differently to bursitis or impingement. Small tears can be managed conservatively with physiotherapy. Larger tears or complete ruptures may require surgical consideration. Assessment at PhysioLogix distinguishes between these presentations clearly — the treatment for a rotator cuff tear is significantly different to the treatment for bursitis.
What Causes Shoulder Bursitis?
The subacromial space is compressed whenever the shoulder moves in a way that narrows the gap between the rotator cuff and the acromion. Several factors increase this compression chronically:
Rotator cuff weakness — the rotator cuff's job is to keep the head of the humerus properly centred in the shoulder socket during movement. When the rotator cuff is weak or activates too late, the humeral head rides up slightly during overhead movements, compressing the subacromial space and the bursa.
Scapular dyskinesis — the shoulder blade needs to rotate and tilt upward as the arm is raised to maintain the subacromial space. When the muscles controlling the shoulder blade — particularly the serratus anterior, lower trapezius, and middle trapezius — are weak or poorly coordinated, the blade doesn't move correctly and the space narrows.
Thoracic stiffness — a stiff upper back limits the thoracic extension and rotation needed for full, pain-free shoulder movement. The shoulder compensates by moving differently, increasing compressive load on the subacromial space.
Pectoral tightness and rounded shoulders — tight pectorals pull the shoulder into internal rotation and forward, which naturally narrows the subacromial space and increases impingement risk.
Training errors — in the gym and sporting populations, shoulder bursitis frequently develops from training programs that overload the pushing muscles (chest, anterior deltoid) without sufficient pulling and rotator cuff work, creating the muscle imbalances listed above.
How We Treat Shoulder Bursitis at PhysioLogix
Assessment covers the glenohumeral joint (the ball and socket), the scapulothoracic joint (where the shoulder blade articulates with the rib cage), thoracic spine mobility, and the rotator cuff and scapular stabiliser muscle function. Both joints need to be working correctly for the shoulder to move pain-free — assessing one without the other is an incomplete picture.
For patients who train in the gym, we can assess movement under load. If your shoulder hurts on bench press, overhead press, or pull-ups, we can watch you perform those movements and identify exactly where the mechanics break down. This level of assessment isn't available at most clinics and is one of the practical advantages of our gym floor setup.
Hands-on treatment includes joint mobilisation to restore restricted shoulder and thoracic movement, soft tissue release targeting the rotator cuff, pectorals, and thoracic extensors, and dry needling where muscle guarding around the shoulder is maintaining the mechanical problem.
Exercise rehabilitation addresses the specific muscular weaknesses and imbalances identified in your assessment. Rotator cuff strengthening, scapular stabiliser activation, and thoracic mobility exercises form the foundation of most shoulder programs. For gym-based patients, the program includes guidance on loading modifications and technique corrections to allow training to continue — modified where necessary — while the shoulder recovers.
Frequently Asked Questions
How long does shoulder bursitis take to resolve?
Acute shoulder bursitis that is caught and treated promptly can resolve within four to eight weeks. Chronic bursitis that has been present for months, or that has been managed with cortisone injections without addressing the underlying mechanical cause, takes longer. Most patients notice meaningful improvement within the first three to four sessions.
Can shoulder bursitis resolve without surgery?
Yes — the vast majority of shoulder bursitis and impingement cases resolve with conservative physiotherapy management. Surgery is rarely required and is typically only considered after an extended period of conservative management has failed to produce improvement. Cortisone injections can reduce inflammation short-term but do not address the mechanical factors causing the problem and are not a long-term solution on their own.
Can shoulder bursitis resolve without physiotherapy?
Some mild cases settle with rest and activity modification. However, if the underlying mechanical factors — rotator cuff weakness, scapular dysfunction, thoracic stiffness — are not addressed, the problem typically recurs when activity resumes. Physiotherapy addresses the cause, not just the inflammation.
Can I keep training with shoulder bursitis?
In many cases, yes — with appropriate load and technique modifications. Complete rest is rarely necessary and can delay recovery. We will advise you specifically on what to avoid and what can continue based on your assessment findings.
Do I need imaging to diagnose shoulder bursitis?
Not usually. Shoulder bursitis and impingement are clinical diagnoses. Ultrasound or MRI can confirm the diagnosis and assess the rotator cuff tendons for tearing, which is useful when there is significant weakness or the presentation is not responding as expected. We'll advise you if imaging would be helpful.
