Being told you have shoulder impingement can bring a mix of emotions—relief at having a label, but also uncertainty about what it actually means and what you should do next.
For many years, this term has been used to describe pain that occurs when lifting your arm or reaching overhead—often linked to issues like bursitis or rotator cuff problems. It’s a familiar diagnosis, and one that might sound straightforward at first.
But over time, our understanding of shoulder pain has evolved. What we now know is that the term “impingement” may not reflect what’s really happening in the shoulder—and in some cases, it can even make recovery more confusing or stressful than it needs to be.
In this article, we’ll gently unpack:
- What shoulder impingement used to mean
- Why the term is no longer considered helpful
- What the latest research says about shoulder pain
- How this shift influences your treatment options—especially surgery vs. physiotherapy
👉 Our aim is simple: to help you make sense of your shoulder pain and feel more confident about your next steps.
📚 Where Did “Shoulder Impingement” Come From?
The concept of shoulder impingement was first described in the 1970s. The idea was simple: something (usually the rotator cuff tendon or the subacromial bursa) was getting “pinched” under the bony arch of your shoulder (the acromion) when you lifted your arm.
This theory led to the belief that bony anatomy—like a hooked acromion—was the root of the problem. As a result, many people were sent for imaging, told they had “impingement,” and offered surgery to shave or reshape the bone to create more space.
But over the last two decades, that theory has come under serious scrutiny.
🚫 Why the Term “Impingement” Is Problematic
There are three key problems with the term “impingement”:
1. It’s part of normal shoulder movement
Research has shown that some contact between the rotator cuff and the bony arch happens during normal, pain-free arm movement. It’s not necessarily harmful.
🧠 Fact: Up to 96% of people without shoulder pain show signs of “impingement” on imaging.
(Lewis, 2011; Michener et al., 2013)
2. It doesn’t explain your pain
Shoulder pain isn’t always caused by something being “pinched.” In many cases, it may come from:
- Tendon overload or irritation
- Poor load tolerance
- Movement patterns or training errors
- Sleep, stress, and general health
💡 Often, symptoms improve with time, movement, and progressive rehab—not by changing your shoulder’s structure.
3. It can lead to fear and unnecessary treatment
The word “impingement” can create the idea that something is stuck or damaged, which may make people avoid movement or rush into surgery.
🔄 A Better Term: Rotator Cuff–Related Shoulder Pain
Today, many clinicians use the term rotator cuff–related shoulder pain (RCRSP) instead. It’s a broader, more helpful way of describing pain that involves the rotator cuff and surrounding structures.
Why it’s a better term:
- ✅ It avoids assuming damage based on scans alone
- ✅ It shifts the focus toward rehabilitation, not anatomy
- ✅ It reflects the complexity of shoulder pain—biological, physical, and even emotional
🛠️ What About Surgery?
If you’ve been told you need surgery to fix your shoulder “impingement,” here’s what you need to know:
Large, high-quality studies (like the CSAW and FIMPACT trials in 2018) found that surgery to remove bone or “make space” (subacromial decompression) was no better than placebo surgery or physiotherapy.
📉 That means people who had the surgery didn’t recover better or faster than those who didn’t.
Today, surgery is generally reserved for:
- Full-thickness rotator cuff tears with significant weakness
- Severe, persistent pain that doesn’t respond to months of structured rehab
- Specific cases where other diagnoses are involved (e.g. instability, fractures)
If your only diagnosis is “impingement,” surgery is unlikely to be the answer.
🏋️♀️ Why Physiotherapy Works
Physiotherapy is now the first-line treatment for rotator cuff–related shoulder pain—and with good reason. The shoulder responds well to movement, strength, and education.
An effective physio plan might include:
- 🧠 Education: Understanding pain helps reduce fear and confusion
- 🧱 Gradual loading: Building tolerance through smart, progressive movement
- 💪 Strengthening: Especially the rotator cuff and scapular muscles
- 🤝 Manual therapy: As needed for short-term pain relief
- 🌱 Whole-person care: Including stress, sleep, posture, work/life factors
With the right guidance, most people improve without the need for imaging or invasive procedures.
✅ What You Can Do Now
If you’ve been diagnosed with “shoulder impingement”:
- Don’t panic—your shoulder is likely not damaged or stuck
- Stay active within your comfort levels
- Seek out a physiotherapist who understands the current evidence
- Focus on building confidence and strength—not avoiding movement
