What is SI Joint Dysfunction?
Sacroiliac (SI) Joint Dysfunction occurs when the joints connecting the sacrum (base of the spine) to the pelvis move abnormally or become inflamed. This can cause lower back, buttock, or groin pain, sometimes radiating down the leg. SI joint dysfunction is estimated to account for 15–30% of chronic lower back pain cases (Vleeming et al., 2012).
Common Causes
• Poor posture or prolonged sitting.
• Trauma or sudden impact to the pelvis or lower back.
• Pregnancy-related pelvic changes.
• Leg length discrepancies or uneven gait.
• Repetitive lifting or twisting movements.
Treatment Options
WCCC management may include:
• Gentle chiropractic adjustments to restore SI joint alignment and mobility.
• Soft tissue therapy to relax surrounding muscles and reduce tension.
• Exercise and rehabilitation to stabilise the core and pelvis.
• Postural and ergonomic guidance for work and daily activities.
• Collaboration with medical professionals if imaging or further intervention is needed.
