The sacroiliac joint plays a essential role in transferring forces between the upper and lower body. Located between the triangular sacrum and the wing-like ilium, 小倉南区 整体 this joint bridges the lower spine and hip bones. While it exhibits minimal motion during daily activities, it acts as a shock absorber between the spine and pelvis. When this joint becomes irritated or dysfunctional, it can lead to chronic lower back discomfort that often mimics other conditions like herniated discs or sciatica.

Pain from the SI joint typically is localized to one side of the pelvis or hip and may extend down the back of the leg. It often worsens with prolonged standing, climbing stairs, or getting up from a seated position. Some people report a sensation of looseness or weakness in the pelvic region. Because the symptoms are indistinguishable from common back conditions, it is routinely mistaken for sciatica or facet syndrome. A careful physical exam and sometimes imaging or diagnostic injections are needed to distinguish it from other causes.

Several factors can lead to SI joint impairment. Hormonal changes during gestation are a major contributor due to relaxin-induced ligament laxity that increases pelvic mobility. Sudden mechanical trauma like a slip or collision can also damage the ligaments or articular surfaces. Repetitive stress combined with unilateral muscle weakness or limb inequality can place excessive mechanical load on the SI complex. In some cases, degenerative joint disease or inflammatory spondyloarthropathies affects the joint.

Treatment focuses on rebalancing motion and suppressing pathological inflammation. Manual rehabilitation typically initiates care, with specific exercises to strengthen the muscles around the pelvis and improve posture. Manual therapy techniques such as joint mobilization may help improve joint glide and reduce stiffness. Oral anti-inflammatories, cold can provide symptom reduction. In more chronic or refractory presentations, SI joint fusion or nerve neuromodulation may be considered.

Preventing sacroiliac joint pain involves maintaining good posture, staying active, and avoiding prolonged sitting or standing in one position. Targeted drills for transverse abdominis, multifidus, and gluteus medius are especially helpful. If you have chronic back discomfort unresponsive to conventional therapies, it’s worth considering whether the sacroiliac joint might be involved. A thorough evaluation by a healthcare provider who understands pelvic mechanics can lead to an precise identification and lasting symptom resolution.
