Don't let sacroiliac joint pain control your life. Our expert physiotherapists in Ancaster & Hamilton identify the root cause to provide lasting relief.
Book My AssessmentThis condition is a common cause of low back pain, but is frequently misdiagnosed. See if these symptoms sound familiar.
SI joint pain accounts for 15-30% of all chronic low back pain, yet it's often missed. We use a proven diagnostic process to confirm the source of your pain, ensuring your treatment is effective from day one.
Our approach combines hands-on manual therapy to restore joint mobility with a targeted exercise program to build the stability needed for long-term relief. We don't just chase symptoms; we fix the underlying problem.

"After months of frustrating lower back and hip pain, Dhiman identified it was my SI joint. The targeted exercises and hands-on work made a world of difference. I can finally sit and stand without that sharp pain!"

"I thought I'd have to give up running. The team at Interlink not only got me out of pain but also built up my core and hip strength to prevent it from coming back. So grateful for their expertise."

We use a cluster of validated clinical tests (Laslett, 2005) to accurately diagnose SI joint dysfunction, distinguishing it from lumbar spine or hip issues to ensure your treatment is correctly targeted.
Targeted manual therapy techniques are used to restore normal joint mechanics, release tight surrounding muscles (like the glutes and piriformis), and reduce pain and inflammation.
We prescribe specific exercises to strengthen the deep core and pelvic stabilizing muscles (like the transversus abdominis) that provide crucial support to the SI joint, preventing recurrence (Richardson, 2002).
We follow a clear, structured process to get you from pain to performance.
A deep dive into your symptoms, history, and movement patterns to pinpoint the exact cause of your SI joint pain.
A combination of hands-on therapy to restore joint function and specific exercises to build stability and control.
We empower you with the knowledge and tools to manage your condition independently and prevent future flare-ups.
Making an informed choice is key to your recovery. Here’s how physiotherapy stacks up against other common approaches for SI joint pain.
Pros: Addresses the root cause of instability/dysfunction, provides long-term relief, and reduces recurrence risk.
Cons: Requires active patient participation and consistency with exercises.
Pros: Can provide powerful short-term pain and inflammation relief.
Cons: Does not fix the underlying mechanical issue; pain often returns. Not a long-term solution.
Pros: May temporarily reduce acute pain.
Cons: Leads to deconditioning, muscle weakness, and increased joint instability, often worsening the problem over time.
Clinical differentiation requires a thorough assessment. SI joint pain is typically more lateral and buttock-dominant, worsens with single-leg loading, and is reproduced by specific provocation tests. Lumbar pain is often more central and related to spinal movements. A physiotherapist can accurately diagnose the source.
A targeted physiotherapy plan can resolve SI joint pain for good. Book your initial assessment today and take the first step towards a pain-free life.
