Shoulder Impingement
Understanding Shoulder Impingement: Causes, Symptoms, and Evidence-Based Physiotherapy Treatment
Shoulder impingement is one of the most common causes of shoulder pain, and can be experienced during various day to day activities like exercising at the gym, swimming laps, or spending long hours at a desk with poor posture. At City Physio in Martin Place, Sydney, we regularly treat patients presenting with shoulder impingement symptoms ranging from mild discomfort to chronic dysfunction.
What Is Shoulder Impingement?
Shoulder impingement, often referred to as subacromial impingement syndrome, occurs when the tendons of the rotator cuff and the bursa become compressed or irritated in the subacromial space—the area beneath the acromion (the top outer edge of the shoulder blade). This can result in inflammation, pain, and reduced range of motion.
The impingement itself is not a diagnosis but a clinical sign that reflects an underlying mechanical dysfunction. It may stem from structural issues (such as a curved acromion or bone spur), or from functional issues like muscular imbalances, scapular dyskinesis, or poor neuromuscular control.
Common Causes of Shoulder Impingement
Shoulder impingement can arise from a variety of sources. These include:
- Repetitive Overhead Activity: Common in sports like tennis, swimming, and functional fitness training.
- Postural Dysfunction: Rounded shoulders and forward head posture can compromise shoulder mechanics.
- Muscle Imbalance: Weakness in scapular stabilisers or rotator cuff muscles can alter joint kinematics.
- Previous Injury: Old injuries, particularly to the rotator cuff, can predispose the shoulder to impingement.
Symptoms to Watch For
Patients with shoulder impingement often describe a gradual onset of pain, particularly when lifting the arm overhead or reaching behind the back. Key symptoms include:
- A painful arc of movement (typically between 60° and 120° of shoulder elevation)
- Weakness or fatigue in the shoulder during overhead tasks
- Pain that worsens at night, especially when lying on the affected side
- A sense of catching, pinching, or stiffness
If left untreated, impingement may progress to rotator cuff tendinopathy or even partial-thickness tears, underscoring the importance of early intervention.
The Role of Physiotherapy in Managing Shoulder Impingement
Physiotherapy is considered a first-line, evidence-based treatment for shoulder impingement. Rather than just addressing pain, physiotherapists aim to identify and treat the root cause of the impingement.
At City Physio, our approach to shoulder impingement typically includes:
1. Comprehensive Assessment
We begin with a detailed biomechanical assessment that evaluates posture, scapular control, muscle strength, joint range of motion, and movement patterns. Identifying the driver of impingement—whether structural or functional—is critical to an effective treatment plan.
2. Manual Therapy
Joint mobilisation, soft tissue release, and dry needling may be used to restore mobility, reduce muscle tension, and alleviate pain in the acute phase.
3. Targeted Exercise Prescription
A personalised exercise program is essential. This may include:
- Scapular stabilisation exercises to improve shoulder blade control
- Rotator cuff strengthening to enhance dynamic shoulder stability
- Postural re-education to correct movement dysfunctions
Exercise dosage, progression, and technique are closely monitored to ensure optimal outcomes.
4. Education and Ergonomic Advice
Patients are empowered with knowledge about activity modification, workplace ergonomics, and long-term injury prevention strategies. This is especially important for office workers or athletes with recurring impingement symptoms.
How Long Does Recovery Take?
Most patients see meaningful improvement within 6 to 12 weeks of consistent physiotherapy, depending on the severity and chronicity of their symptoms. Long-standing cases may take longer, particularly if there is associated rotator cuff pathology. Adherence to a structured rehab program significantly enhances outcomes.
When to Consider Imaging or Specialist Referral for Shoulder Impingement
If symptoms persist despite conservative management, referral for imaging (such as ultrasound or MRI) may be appropriate to rule out more significant pathology, such as a rotator cuff tear. In rare cases, surgical intervention such as subacromial decompression may be considered—but only after a comprehensive physiotherapy rehab program fails to yield improvement.
