The 4 Stages of Frozen Shoulder: What Your Shoulder Needs at Each One

By Helen Zhang, Balanced Body® Pilates Educator, My Body My Pilates

If you have frozen shoulder, you've probably heard that it happens "in stages". What people rarely explain is what that means for you day to day: what your shoulder can handle right now, what it needs, and what is likely to make it worse.

After years of working with frozen shoulders in my Tokyo studio, I've found that this is the question that matters most. Not "Which exercises should I do?" but "What does my shoulder need at this stage?"

How doctors describe the phases

Medically, frozen shoulder (adhesive capsulitis) is usually described in three overlapping phases:

• Freezing: pain builds and the shoulder gradually loses movement. Pain is often worse at night.
• Frozen: pain may ease a little, but the shoulder is very stiff and movement is limited in many directions.
• Thawing: movement slowly returns.

Each phase can last months, and the whole process often takes a year or more. The timing varies a lot from person to person.

These phases describe what is happening to your shoulder. They're useful, but they don't tell you what to do. That's why I work with four stages based on what your shoulder is ready for.

The 4 stages of recovery

Stage 1: Frozen / Stiff

What it feels like: your shoulder is painful, guarded and tight. Simple things like putting on a jacket, reaching behind you or lying on that side can be difficult. The muscles around your shoulder, neck and upper back are working hard to protect the joint.

What your shoulder needs: calm, not force. The aim is to reduce the protective tension, get blood moving and gently start creating space around the joint, including getting the shoulder blade moving again.

What tends to backfire: pushing hard into stretches to "get the movement back". A shoulder that is still guarding usually responds by guarding more.

Stage 2: Recovering / Create Space

What it feels like: the pain is less constant and your shoulder starts to allow a bit more movement. You may notice good days and bad days.

What your shoulder needs: more space and length, and better balance between the muscles that control your shoulder. This is when your arm, shoulder blade and spine start relearning how to move together.

What tends to backfire: jumping straight to strength work because you feel better. This is the stage where many people skip ahead, and it's often where they get stuck.

Stage 3: Strengthening

What it feels like: most of your movement has returned, but your shoulder may feel weak or unreliable, especially when you carry things or reach overhead.

What your shoulder needs: a stable shoulder blade that can support your arm, and strength that works together with your spine. This is what makes your regained movement usable in daily life.

What tends to backfire: building strength on top of old compensations, like hitching your shoulder up towards your ear when you lift your arm.

Stage 4: Maintain

What it feels like: your shoulder is close to normal and everyday movements feel easy again.

What your shoulder needs: regular practice to keep it mobile, stable and strong, at a level that suits your life.

Why your shoulder blade and spine matter

When you lift your arm, three areas move together: the shoulder joint, the shoulder blade and the spine. With frozen shoulder, most attention goes to the joint, but the shoulder blade and upper back often become stiff too, and the way they move changes.

That's why recovery isn't only about the joint "loosening up". It's about getting all three working together again, in the right order.

How to tell which stage you're in

Your stage is not decided by how many weeks have passed. Two people who started at the same time can be at very different points. A few useful questions:

• Is your shoulder painful at rest or at night, or mainly when you move it?
• Does movement feel blocked by pain, or blocked by stiffness?
• When you lift your arm, does your shoulder hitch up towards your ear?
• Can you carry a bag or reach overhead without your shoulder feeling unstable?

If you're unsure, I made a short Frozen Shoulder Stage Quiz. It takes a few minutes and tells you which stage you're likely in, along with what that means for how you move.

Moving on only when you're ready

Each stage prepares your shoulder for the next one. Moving on before you're ready is the most common reason people feel they've "gone backwards". Staying a little longer in a stage isn't failing. It's how you build a recovery that lasts.

This is the idea behind Move Again, my online frozen shoulder program. It takes you through the stages in order, with simple checkpoints between them, so you always know what to work on now and when you're ready to progress. There's no deadline. Your body sets the pace.
