What Is Sacroiliac Joint Dysfunction?

The sacroiliac joints are located on either side of the lower spine where the sacrum meets the pelvis. These joints play an important role in providing stability while allowing a small amount of movement. Sacroiliac joint dysfunction occurs when the joint becomes irritated, inflamed or is not functioning efficiently, resulting in pain and reduced mobility. Symptoms can sometimes mimic other causes of lower back pain, making a thorough assessment important.

Common Symptoms of Sacroiliac Joint Dysfunction

Symptoms vary between individuals but may include:

✔ Pain in the lower back

✔ Pain on one side of the pelvis

✔ Buttock pain

✔ Pain that may extend into the groin or thigh

✔ Stiffness when standing after sitting

✔ Pain when walking or climbing stairs

✔ Discomfort when rolling in bed

✔ Difficulty standing for prolonged periods

✔ Reduced mobility and flexibility

✔ Pain during certain movements or activities

Common Causes of Sacroiliac Joint Dysfunction

Sacroiliac joint symptoms may develop due to a variety of contributing factors, including:

✔ Repetitive lifting and bending

✔ Sporting activities

✔ Workplace injuries

✔ Falls or trauma

✔ Pregnancy and post-partum changes

✔ Altered walking patterns

✔ Muscle weakness around the pelvis and trunk

✔ Leg length differences

✔ Previous back or pelvic injuries

✔ Arthritis affecting the sacroiliac joint

Because symptoms can overlap with disc, facet joint and muscle-related conditions, an individual assessment is important before deciding on the most appropriate rehabilitation approach.

Assessment and Diagnosis

Your clinician will discuss your symptoms, medical history, daily activities, work demands and rehabilitation goals. The assessment may include movement testing, pelvic and spinal assessment, strength testing, mobility assessment, functional testing and review of imaging reports where relevant. A thorough assessment helps determine whether the sacroiliac joint is contributing to your symptoms and identifies factors affecting your movement and function.

How Physiotherapy May Help

Physiotherapy may assist with improving movement, reducing stiffness and restoring function. Treatment may include education, movement modification strategies, mobility exercises, strengthening exercises, hands-on treatment where appropriate and rehabilitation aimed at improving pelvic and trunk stability. Recommendations will depend on your assessment findings and individual goals.

Exercise Rehabilitation for Sacroiliac Joint Dysfunction

Exercise rehabilitation is often an important component of managing sacroiliac joint dysfunction. Programs may focus on improving core strength, pelvic stability, hip strength, mobility, balance and overall physical conditioning. Exercises are tailored to your presentation and progressed as your function improves.

Hydrotherapy for Sacroiliac Joint Dysfunction

Hydrotherapy may be beneficial for some people experiencing sacroiliac joint pain. The buoyancy of the water reduces loading through the pelvis and lower back, allowing exercise in a supported, low-impact environment. Hydrotherapy may assist with improving mobility, strength, endurance and confidence with movement.

Pelvic and Spinal Rehabilitation Programs

Some individuals with persistent symptoms, recurring episodes of pain or more complex presentations may benefit from a structured rehabilitation program. Rehabilitation may focus on improving movement patterns, restoring strength, increasing activity tolerance, returning to work and developing strategies to support long-term spinal and pelvic health.

When Should You Seek Medical Advice?

While many cases of sacroiliac joint dysfunction respond well to rehabilitation, some symptoms may require medical assessment. You should seek medical advice if you experience significant trauma, severe or worsening symptoms, loss of strength, significant numbness, changes in bladder or bowel function, unexplained weight loss or symptoms causing significant concern. Your clinician may also recommend further medical review where appropriate.
