Frozen Shoulder Physiotherapy — Erina & Central Coast
Frozen shoulder is one of the more misunderstood conditions we treat. Patients often arrive confused about why a shoulder that was never injured has become so stiff and painful, and worried that something has been badly damaged. In most cases, nothing is torn or broken — the shoulder capsule itself has simply tightened up, and there's a well-recognised process for working through it.
What Is Frozen Shoulder?
Frozen shoulder, medically known as adhesive capsulitis, happens when the capsule surrounding the shoulder joint becomes thickened and inflamed, gradually restricting how far the joint can move. It typically develops without any clear injury and can affect people who've never had shoulder problems before. It's more common in people aged 40 to 60, and more common in women and in people with diabetes or thyroid conditions.
What makes frozen shoulder particularly disorienting for a lot of patients is the mismatch between how it feels and what's actually happening structurally. There's no tear, no instability, no damage that shows up dramatically on a scan — just a capsule that has become tight and inflamed, restricting movement in every direction rather than one specific plane. Understanding that distinction often brings real relief on its own, separate from any treatment we provide.
The Three Stages
Frozen shoulder tends to move through three distinct phases, and understanding which one you're in changes what treatment should focus on:
Freezing phase —
increasing pain, often worse at night, with movement gradually becoming more limited
Frozen phase —
pain often eases somewhat, but stiffness is now significant and day-to-day tasks become difficult
Thawing phase —
movement slowly returns, sometimes over several monthsWithout treatment, the whole process can take well over a year, and sometimes considerably longer. The stages don't always follow a neat timeline, which is part of why this condition can feel so unpredictable if you're going through it without guidance. Some people move through all three stages in around a year, while others find the frozen phase drags on considerably longer before movement starts to return.
How We Diagnose It
Frozen shoulder is usually diagnosed through a clinical assessment of your shoulder's movement, particularly rotation, which is often the most restricted direction. We'll also ask about your broader health history, since conditions like diabetes are relevant to how frozen shoulder tends to progress. Imaging isn't usually needed to confirm the diagnosis, though it can occasionally be used to rule out other causes of stiffness if the picture isn't clear-cut.
How Physiotherapy Helps
Treatment is tailored to whichever stage you're in. During the painful freezing phase, the priority is calming things down — gentle movement within a comfortable range, pain management strategies, and honest advice about pacing your activities rather than pushing through pain. As you move into the frozen phase, treatment shifts toward carefully restoring range of motion without provoking a flare-up. In the thawing phase, we focus on rebuilding strength and normal movement patterns, since the muscles around a stiff shoulder often weaken over the months it's been restricted.We won't promise physiotherapy can skip you straight to full recovery — frozen shoulder has its own timeline — but the right guidance genuinely improves pain levels, protects your sleep, and helps you keep functioning through what can otherwise be a very long and frustrating process. In some cases, we'll also liaise with your GP about additional options like a cortisone injection to help settle an especially painful freezing phase.Because frozen shoulder unfolds over months rather than weeks, we build your program around regular check-ins so we can adjust the plan as you move between stages, rather than sending you away with a single set of exercises for the entire journey.
Self-Care While You Wait For Your Appointment
If you're in the early, painful freezing phase, avoid forcing movement into painful ranges, and consider using extra pillows for support when sleeping. Gentle pendulum-style arm swings, kept well within a comfortable range, can help maintain some movement without provoking flare-ups. If diabetes or a thyroid condition is part of your health history, mentioning this at your first visit helps us give you a more accurate sense of how your recovery is likely to progress.
Frequently Asked Questions
How long does frozen shoulder actually last?
It varies significantly, but many cases run anywhere from six months to two years from start to finish. Getting the right support early tends to make the experience considerably more manageable, even if it doesn't dramatically shorten the total timeline.
Should I keep moving my arm or rest it?
Gentle, guided movement is generally better than complete rest, which can allow stiffness to worsen. We'll show you exactly how far to push and when to ease off, based on which stage you're in.
Can frozen shoulder come back once it's resolved?
It's uncommon for frozen shoulder to recur in the same shoulder once it's fully resolved, though it can occasionally develop in the opposite shoulder at some point afterward.
