Stretching a painful shoulder might be making it worse. Here’s the science.

Most people’s first instinct when their shoulder hurts is to stretch it. It feels tight, so loosening it up must help….right?

Not always. In fact, for a large number of people dealing with shoulder pain, more flexibility is the last thing they need. What’s actually missing is stability, the ability to control the shoulder through its range of motion, not just access it.

When the muscles responsible for stabilizing the joint are underperforming, the shoulder becomes vulnerable under load. Stretching into that range without the control to support it doesn’t make the joint safer. It can make it less predictable and more irritable.

This is one of the most common reasons people stay stuck in a cycle of pain. They keep addressing the symptom (the tightness) without addressing the underlying driver, which is a lack of neuromuscular control and strength in the muscles that keep the joint centred.

A physiotherapy assessment is designed to identify exactly this. Is your shoulder lacking mobility, stability, or both? The answer changes the entire approach to treatment and getting that clarity early is what separates people who recover quickly from those who spend months guessing.

Slide through to understand the difference — and why the right approach matters.

A rotator cuff finding on imaging doesn’t automatically mean surgery or permanent damage. In fact, research shows that a significant percentage of people with no shoulder pain at all have rotator cuff findings on MRI, meaning the image alone tells you very little about why you’re hurting.

Tendinopathy is far more common than full tears, and unlike what many people assume, it responds extremely well to progressive loading. The tendon isn’t broken, it’s irritated, sensitized, and under-conditioned. The fix isn’t rest or surgery. It’s the right load, at the right time, applied consistently.

The key is understanding what stage you’re in and matching your approach to that stage of recovery because doing too much too soon is just as counterproductive as doing nothing at all.

This is where working with a physio makes a real difference. Rather than following a generic protocol, a structured assessment identifies exactly where you are in the recovery process and builds a plan that progresses with you so you’re always doing the right amount of the right thing at the right time.

Recovery from rotator cuff issues is rarely linear, but with the right guidance it is achievable. Most people don’t need surgery. They need a smarter plan.

Progressive loading beats passive rest. Every time.💪🏽

Recovery isn’t built on motivation.
It’s built on consistency.

✔ Show up tired
✔ Show up unmotivated
✔ Just don’t stop showing up

Your comeback depends on what you do today. 💪🦵

And we are here for you no matter how you show up.

At Rock & Armor, we don’t guess when it comes to knee rehab.
We test.
Because pain is a symptom — but function is capacity.
Here are the 3 tests we use to assess knee function and guide return to sport or running 👇

1️⃣ Isokinetic Testing
This tells us what the joint can actually produce.

We assess:

• Quadriceps peak torque

• Hamstring peak torque

• Limb symmetry index (LSI)

• Strength ratios
Why it matters:

The quad is the primary shock absorber of the knee. If it’s underpowered, the joint absorbs load passively instead of actively.

We’re typically looking for:

✔ ≥ 90% limb symmetry (higher for cutting athletes)

✔ Strong quad output through full range

✔ Balanced hamstring:quad ratio
Strength deficits don’t always show up in bodyweight testing — but they will show up under velocity-controlled resistance.

2️⃣ Anterior Reach / Forward Step Down
This assesses force absorption and control in the sagittal plane.

What we’re watching:

• Knee tracking over 2nd–3rd toe

• Pelvic control

• Controlled eccentric lowering

• No dynamic valgus

• No pain > 2/10

Typical benchmark:

✔ 8–10 controlled reps from 6–8” step

✔ Symmetrical depth and control
Why it matters:

Running is repeated single-leg deceleration. If you can’t control a forward step-down, you’re not ready to absorb ground reaction forces.

3️⃣ Lateral Step Down
This exposes frontal plane deficits.
What we’re watching:

• Hip drop

• Knee collapse inward

• Trunk compensation

• Foot stability

Benchmark:

✔ 8–10 slow, controlled reps

✔ Level pelvis

✔ No valgus collapse

✔ Pain ≤ 2/10

Why it matters:

Most knee pain isn’t just sagittal-plane weakness. Frontal plane control protects the joint from excessive compressive and shear forces.

Here’s the key:
✔ Strength (isokinetic)

✔ Sagittal plane control (forward step down)

✔ Frontal plane control (lateral step down)
If one pillar is missing, the knee isn’t fully ready.
Rehab isn’t about waiting for pain to disappear.
It’s about restoring capacity.
Test.

Build.

Retest.
That’s how we help people return stronger than before.
Your comeback starts here.

At Rock and Armor Physical Therapy and Sports Performance, we don’t just rehab injuries—we build sports-specific plans that match the real demands of the game.

✔️ Knee stability
✔️ Rotational strength
✔️ Footwork + return-to-throw progressions
✔️ Confidence to get back under center

Our goal?
Help you heal the right way so you can return stronger than before. 🔥

RUNNING AGAIN AFTER KNEE PAIN?

Pain going down ≠ knee ready for impact.
Your knee must prove it can:

✔ Absorb force
✔ Create force
✔ Demonstrate elasticity
✔ Translate forward under load

Here’s a simple return-to-run readiness screen you can use 👇

1️⃣ Single-Leg Squat
👉 20 controlled reps
• Knee tracks over 2nd–3rd toe
• No hip drop or knee cave
• Pain ≤ 2/10

Why: Tests single-leg load tolerance & frontal plane control.

2️⃣ Single-Leg Bridge
👉 25 reps each side
• Full hip extension
• No hamstring cramping
• Pelvis stays level

Why: Glute strength protects knee loading mechanics.

3️⃣ Single-Leg Calf Raises
👉 25–30 reps
• Full height each rep
• Controlled tempo
• No bouncing

Why: Calf complex absorbs up to 6–8× bodyweight during running.

4️⃣ Pogo Hops (In Place)
👉 30 seconds continuous
• Quiet landings
• Minimal knee bend
• Spring-like stiffness

Why: Tests tendon elasticity & energy storage.

5️⃣ Forward Pogo Hops / Bounds
👉 20 controlled contacts
• Stable landings
• No pain spike
• Maintain rhythm

Why: Introduces forward translation & reactive loading.

✅ If you pass all tests pain-free (≤2/10)
✅ No swelling within 24 hours
✅ Symmetry side-to-side
➡️ You’re likely ready to begin graded return-to-running.
🚨 If symptoms spike, swelling appears, or confidence drops your knee isn’t failing.

It’s asking for more capacity first.

Build strength.
Build elasticity.
Build resilience.

That’s how runners stay running.

Save this for when you’re ready to return.

Share it with a runner who keeps “testing” their knee too soon.
Your comeback starts here.
