If you’ve been told you have “shoulder impingement,” “a bit of bursitis,” or “a rotator cuff issue,” you may have left the appointment more worried than when you walked in — especially if the word tear came up. Here’s some news that surprises most people: the way we understand and name this problem has changed, and for the vast majority of people, the outlook is far more reassuring than those labels suggest.
At Pottsville & Cabarita Physio, we see this presentation constantly. It’s one of the most common reasons people across the Tweed Coast come through our door with a sore shoulder — whether they’re paddling out at Cabarita, hauling shopping, sleeping poorly on one side, or reaching into an overhead cupboard and wincing.
What is Rotator Cuff Related Shoulder Pain (RCRSP)?
Rotator Cuff Related Shoulder Pain, or RCRSP, is the current umbrella term physiotherapists and researchers use for a group of conditions that share the same clinical picture: pain and weakness in the shoulder, most noticeably when you lift your arm out to the side or rotate it outward.
RCRSP gathers under one roof several diagnoses you may have heard before:
- Subacromial pain (impingement) syndrome
- Rotator cuff tendinopathy
- Subacromial bursitis
- Partial- and full-thickness rotator cuff tears (both the atraumatic, wear-and-tear kind and traumatic tears)
It’s genuinely common. RCRSP is thought to be the most frequent musculoskeletal shoulder problem, and the great majority of shoulder pain presentations fall into this category. It shows up more often in people who do a lot of overhead activity — think tradies, swimmers, surfers, and anyone lifting arms above shoulder height repeatedly.
Why the name changed (and why that’s good news for you)
For decades, the go-to explanation was “impingement” — the idea, first proposed in the 1970s, that the rotator cuff tendons were being pinched or rubbed against the bony arch above them (the acromion) every time you raised your arm. It’s an intuitive picture, and it drove a whole era of treatment, including a surgery called subacromial decompression that shaved bone away to “make room.”
The trouble is, the evidence hasn’t backed it up. High-quality research has shown that subacromial decompression surgery performs no better than a placebo procedure. Mechanical factors that were once blamed — a narrower space under the acromion, the shape of your acromion, “scapular dyskinesis” — don’t appear to be the straightforward villains they were made out to be.
So the field moved on. The term RCRSP was deliberately chosen to:
- Retire outdated, mechanically-flawed labels like impingement.
- Reflect that the exact tissue at fault is usually impossible to pinpoint — and often doesn’t need to be.
- Reduce the fear that comes with words like “tear,” which can make people believe surgery is inevitable when it usually isn’t.
That last point isn’t just semantics. Research shows the label you’re given genuinely changes how you feel about your options — patients told they have a “rotator cuff tear” or “impingement” are far more likely to think they need an operation, even when the evidence says conservative care would serve them just as well.
What actually causes it?
The honest answer is that RCRSP is multifactorial, and the precise pain mechanism isn’t fully understood. It’s rarely just one thing “pinching.” A more useful way to think about it is load versus capacity — symptoms often appear after a period of increased demand on the shoulder, or when the shoulder’s ability to cope with normal load has dropped.
Factors that reduce your shoulder’s capacity to handle load include some that have nothing to do with the shoulder itself:
- Poor or disrupted sleep
- High stress
- A recent drop in physical activity
- Smoking
- Poor nutrition
That’s why good physio treats the person, not just the joint.
How we diagnose it (and why we usually don’t rush to a scan)
A skilled physiotherapy assessment is the foundation. The pattern we look for is pain and loss of strength during shoulder elevation and external rotation. We’ll assess your movement, your strength, how your shoulder blade moves — and importantly, we’ll check your neck and thoracic (mid-back) spine too, because stiffness there can drive or feed into shoulder symptoms (more on that in our companion article).
You might be surprised that we often don’t recommend an immediate scan. Here’s why: imaging like MRI and ultrasound frequently finds “abnormalities” — including rotator cuff tears — in people who have no pain at all. What shows up on a scan often doesn’t match how the shoulder feels or functions. Rushing to imaging can lead to misdiagnosis, unnecessary worry, and treatment aimed at a picture rather than a person.
The treatment that works: graduated exercise
Here’s the headline every RCRSP patient deserves to hear: a well-constructed, progressive exercise programme is the main treatment, and for most presentations it delivers results at least as good as surgery — including for subacromial pain, rotator cuff tendinopathy, partial-thickness tears, and even atraumatic full-thickness tears.
Good rehab for RCRSP typically involves:
- Progressive loading of the rotator cuff and surrounding muscles — building strength and, crucially, capacity over time.
- Restoring movement and confidence, so you stop guarding the shoulder.
- Addressing the mid-back and neck, so the whole system moves well together.
- Managing load smartly — modifying (not abandoning) aggravating activities while you build resilience.
- Looking at the bigger picture — sleep, stress and general activity levels, which all influence recovery.
It’s not a quick fix, and it does ask something of you — consistency matters. But it works, it avoids the risks and downtime of surgery, and it leaves you with a stronger, more capable shoulder than you started with.
When is surgery considered?
International guidelines are clear: conservative, exercise-based care comes first, and surgery is reserved for the minority who don’t respond to a proper trial of it (or for specific traumatic injuries). One frustrating pattern the research has flagged is people receiving imaging, injections and even surgery before they’ve had a fair go at guided exercise. We’d rather help you get that fair go.
The take-home
If you’ve got a nagging, weak, painful shoulder, you’re not broken — you very likely have a common, treatable condition, and the strongest evidence points to active rehab rather than the operating table. The label matters less than the plan.
