Sacroiliac Joint Pain
What physiotherapy assessment for sacroiliac joint pain involves, and how care is decided.
This page is patient education — it is not a diagnosis, and it does not replace being assessed.

Common symptoms and signs
The sacroiliac joints sit between the spine and the pelvis. Pain here is often mistaken for lower back or hip pain.
- Pain low down on one side, around the dimple above the buttock
- Discomfort with standing on one leg, climbing stairs or turning in bed
- Pain that may spread into the buttock or the back of the thigh
- Symptoms provoked by prolonged sitting or asymmetrical standing
These are the things people commonly describe. They are not a checklist for diagnosing yourself — the same symptoms can come from more than one problem, which is what an assessment is for.

Possible causes and contributing factors
Factors commonly associated with this problem. Association is not the same as cause — the same problem has different contributors in different people, and finding yours is part of what assessment does.
- A period of altered loading, such as pregnancy or a change in activity
- A fall onto the buttock or a jarring step
- Asymmetrical habits — standing on one leg, carrying on one side
- Reduced strength around the hip and trunk
When to seek help
When to consider physiotherapy
- The problem has not settled over a few weeks, or keeps returning
- It is limiting work, sleep, driving or looking after your family
- You are avoiding activity because you are not sure what is safe
- You have been told to "live with it" and want it properly assessed
You do not need to be certain this is you. If you are unsure, describe it to the practice and you will be told plainly whether physiotherapy is the right next step.

How physiotherapy assesses this problem
The same assessment-led approach applies whatever the problem turns out to be. Nothing is treated before it has been assessed.
Step 1: History
What happened, how it behaves through the day, what makes it better or worse, and what it is currently stopping you doing.
Step 2: Movement and strength testing
How the area moves, how much it can produce and tolerate, and how the surrounding joints and muscles are compensating.
Step 3: Functional testing
The specific tasks that are difficult — reaching, stairs, walking, gripping, sitting — tested rather than described.
Step 4: Explanation and plan
What the findings suggest in plain language, including what remains uncertain, and what the first stage of care would involve.
Treatment approach
What care works on, rather than what it promises. What is appropriate for you is decided at the assessment, not from a website.
Identifying the loads, positions and activities involved, and adjusting them deliberately rather than resting completely.
Working on the range and quality of movement that has been lost, at a pace the area can tolerate.
Progressive strengthening so the area can take the load your daily life or sport actually asks of it.
Staged return to work, prayer, driving, lifting or sport, with the criteria for progressing made clear.
Treatments that may be used
These are techniques a physiotherapist may use. Listing one here is not a recommendation, and none of them is decided before you have been assessed.

Who would treat this?
You do not choose a physiotherapist. Describe the problem, and the practice assigns the one whose clinical focus fits it — then reviews that as the picture becomes clearer.

About this problem and assessment — draft copy for clinical review, not personal medical advice.
Do I need a scan before I book physiotherapy?
Usually not. Most back and neck problems are assessed with your history and movement first. If your story or examination suggests something that needs imaging, a doctor arranges that — a scan on its own does not always change what physiotherapy can safely start with.
Should I stay in bed until the pain settles?
Complete bed rest is rarely the best approach. For most non-specific back and neck pain, staying generally active within what you can tolerate, and adjusting painful loads, is consistent with current guidance — while red-flag symptoms still need medical assessment first.
Is sacroiliac pain the same as sciatica?
They can overlap in the buttock and thigh, but the source and provocative movements often differ. Assessment uses specific loading tests and your history rather than assuming every buttock pain is the same problem.
Booking this practice
How do I book an appointment?
Message the practice on WhatsApp with a short description of your problem. The coordinator will reply during clinic hours to arrange a time.
Can I choose which physiotherapist I see?
Booking is with the practice rather than an individual. After you describe the problem, the practice assigns the physiotherapist whose clinical focus fits it. You can read about the team on the physiotherapists page.
Questions about your own case
How long recovery takes, whether you need a scan, and what is safe to do in the meantime all depend on your assessment. Those are worth asking a physiotherapist rather than a website — describe your situation and you will get an answer about you.
