SI Joint Dysfunction Treatment
Targeted chiropractic care to restore normal pelvic motion and relieve one-sided low back and buttock pain.
Sacroiliac (SI) joint dysfunction is pain caused by abnormal motion or inflammation in the joints that connect the base of the spine to the pelvis, usually felt as one-sided lower back or buttock pain that worsens with sitting, standing, or climbing stairs.
Understanding SI Joint Dysfunction
You have two sacroiliac joints, one on each side, where the triangular sacrum at the base of your spine meets the wings of the pelvis. These joints are wrapped in thick ligaments and are built for stability rather than movement, transferring load between your spine and your legs every time you walk, sit, or stand. When one of them becomes stuck and moves too little, or loosens and moves too much, the result is the deep, nagging, one-sided pain that defines SI joint dysfunction.
At Advanced Wellness Chiropractic in Bridgeton, MO, SI joint dysfunction is one of the most commonly missed drivers of one-sided lower back pain. Patients often arrive after weeks or months of being treated for a disc or a muscle strain that never quite added up, because the true source was the pelvis the whole time. The pain typically sits low and to one side, just below the belt line, and can refer into the hip, groin, or upper thigh.
The key to getting it right is a careful exam that distinguishes SI joint pain from sciatica and from true hip pain, since each one looks similar from the outside but responds to a different treatment plan. Once the pelvis is identified as the likely source, conservative care is usually the first step.
When to Seek Immediate Medical Care
Most SI joint and low back pain responds well to conservative chiropractic care, but certain warning signs mean you should go to an emergency department or contact your primary care provider right away rather than waiting for a chiropractic evaluation:
- •Loss of bowel or bladder control, or a sudden change in your ability to urinate or have a bowel movement.
- •Saddle numbness, meaning loss of sensation between the inner thighs, groin, or buttocks, as if you were sitting on a saddle.
- •Sudden severe weakness in one leg, particularly a foot that drags or slaps the ground.
- •Fever combined with back pain, or back pain paired with unexplained weight loss, which can signal infection or other systemic illness.
- •Severe pain following significant trauma such as a car accident, fall from a height, or direct blow to the pelvis.
Common Symptoms
SI joint dysfunction has a recognizable pattern once you know what to look for. The following are the symptoms our patients report most often.
- Pain low on one side of the back or buttock
- Pain that radiates into the hip or groin
- Pain worse with prolonged sitting or standing
- Sharp pain when rolling over in bed
- Stiffness in the pelvis and low back
- Pain climbing stairs or stepping up
- Discomfort rising from a seated position
- A feeling that the pelvis is locked or off-balance
Three Self-Checks You Can Try at Home
These are simplified versions of the provocation tests Dr. JC uses in the office to decide whether your pain is coming from the SI joint rather than the disc or hip. None of them replace a proper exam, but if one or more reproduces your familiar one-sided pain, the pelvis is a likely culprit. Stop any check that causes sharp pain or sudden weakness, and skip them entirely if you have any of the red-flag symptoms above.
The One-Finger Test
How to do it
When your pain is at its worst, point with one finger to the exact spot that hurts most without thinking about it too hard.
What to watch for
If your finger lands on the small bony dimple just below the belt line and to one side of the spine, that points toward the SI joint. Pain you wave a whole hand over is more typical of muscular or disc pain.
What it suggests
A precise, one-sided point of pain over the joint is one of the most consistent signs that the sacroiliac joint is the source.
Figure-4 Position (FABER)
How to do it
Lie on your back and rest the ankle of the painful side on the opposite bent knee, making a figure 4. Let the bent knee relax gently toward the floor.
What to watch for
Pain felt in the back of the pelvis or buttock on the side being tested. Pain felt deep in the groin instead usually points toward the hip joint rather than the SI joint.
What it suggests
Reproducing your typical buttock pain in this position is a classic sign of SI joint involvement and helps separate it from a hip problem.
Single-Leg Stand
How to do it
Stand near a counter or wall for safety. Slowly lift the knee on your painful side up toward your chest as if marching, and hold the single-leg position briefly.
What to watch for
A pinch or deep ache low in the back or buttock on the standing or lifting side, or a sense that the pelvis feels unstable as you load it.
What it suggests
Pain or instability when loading one side of the pelvis suggests the SI joint is not transferring load smoothly, a hallmark of dysfunction.
If one or more of these reproduces your familiar pain, the next step is a full evaluation. Dr. JC will examine the pelvis, lumbar spine, and hips together to confirm the SI joint is the driver and rule out sciatica or a hip issue before building your plan.
How Chiropractic Care Helps
Chiropractic care helps SI joint dysfunction by addressing the mechanics of the joint directly. A precise chiropractic adjustment restores normal motion to a sacroiliac joint that has become stuck or misaligned, which relieves the irritation and inflammation responsible for the pain. Because the SI joint is meant to move only slightly, restoring that small, normal glide often produces noticeable relief.
Adjustments are only part of the picture. The muscles around a dysfunctional SI joint, especially the glutes and deep hip rotators, tend to tighten and guard, which keeps pulling the joint back out of position. Soft-tissue work such as the Graston Technique and Active Muscle Release addresses this tension, and flexion-distraction, a gentle, table-assisted stretching technique, may be used when the surrounding lumbar spine is also involved.
Conservative, hands-on care is commonly tried for sacroiliac and mechanical low back pain before injections or surgery are considered. Just as important as relieving the current flare-up is keeping it from returning, which is where pelvic stabilization exercises come in. Retraining the deep core and hip muscles to hold the pelvis steady is meant to help you manage the condition long-term.
Our Treatment Approach
We tailor every SI joint treatment plan to the individual based on a thorough examination of the pelvis, lumbar spine, and hips. Your care plan may include:
SI Joint Adjustments
Precise, low-force adjustments to restore normal motion to a sacroiliac joint that has become stuck or misaligned.
Flexion-Distraction Therapy
A gentle, non-thrusting, table-assisted stretching technique used when the lumbar spine is also contributing to the pain.
Soft-Tissue & Instrument-Assisted Work
Graston Technique and Active Muscle Release to release the tight glutes and hip rotators that keep pulling the joint out of position.
Pelvic Stabilization Exercises
Targeted core and hip retraining to help the pelvis stay steady between visits.
Home Exercises for SI Joint Relief
These are the exercises Dr. JC most often sends home with SI joint patients. The goal is to calm the joint, release the muscles that crowd it, and rebuild the deep stability that keeps the pelvis steady. Keep every movement gentle and pain-free, and stop any exercise that sharpens your one-sided pain or makes it travel down the leg.
Figure-4 Glute Stretch
Releases the deep gluteal muscles that tighten and guard around a dysfunctional SI joint.
- Lie on your back with both knees bent and feet flat on the floor.
- Cross the ankle of your painful side over the opposite knee in a figure 4.
- Reach through and gently pull the supporting thigh toward your chest.
- Feel the stretch deep in the buttock of the painful side. Hold, then ease off.
Dosage: Hold 30 seconds, 3 reps, twice daily.
Glute Bridge
Strengthens the glutes and posterior pelvis so the SI joint is supported through everyday movement.
- Lie on your back with knees bent and feet flat, hip-width apart.
- Squeeze your glutes and lift your hips until your body forms a straight line from knees to shoulders.
- Keep the pelvis level and avoid arching the low back.
- Lower slowly with control. Keep the lift even on both sides.
Dosage: 10 reps, 2 sets, once daily.
Pelvic Tilts
Wakes up the deep core that stabilizes the pelvis and eases early-morning stiffness in the low back.
- Lie on your back with knees bent and feet flat on the floor.
- Gently flatten your low back into the floor by tilting your pelvis slightly upward.
- Hold for 3 seconds, then release to neutral.
- Keep the motion small and controlled. No forceful pushing.
Dosage: 10 reps, 2 sets, twice daily.
Adductor Squeeze
Gently engages the inner-thigh and pelvic-floor muscles that help compress and stabilize the SI joints.
- Lie on your back with knees bent and feet flat on the floor.
- Place a small pillow or rolled towel between your knees.
- Gently squeeze the pillow with both knees to about half your effort.
- Hold for 5 seconds, then relax. Keep the pressure smooth, never straining.
Dosage: 10 reps, 2 sets, once daily.
A note from Dr. JC
Home exercises are powerful, but they are one piece of a larger plan. Most patients with SI joint dysfunction also have a joint that is stuck or moving abnormally, and stabilization work alone will not restore that motion. If your symptoms are not clearly improving after two to three weeks of consistent home exercise, or the pain keeps returning to the same spot, come in for an evaluation so we can find and treat what is driving it.
Who We See with SI Joint Pain in Bridgeton & St. Louis
Certain jobs, activities, and life stages drive most of the SI joint cases we treat at Advanced Wellness Chiropractic. If you recognize yourself in one of these, you are not alone, and conservative care is often the first step.
Pregnant patients
SI joint pain is one of the most common complaints of the late second and third trimesters, as pregnancy hormones loosen the pelvic ligaments and the joint becomes less stable. If you are pregnant, check with your obstetric clinician before starting care. Positioning and techniques are adapted to your stage of pregnancy, and new or worsening symptoms should go to your obstetric clinician.
Postpartum moms
The pelvis stays loose for months after delivery, and constant lifting, carrying, and one-sided nursing positions can keep an SI joint irritated. We see this pattern often in new mothers across North County.
Centene & WWT desk workers
Patients from Centene, World Wide Technology, Edward Jones, and other corporate offices who sit eight-plus hours a day. Prolonged sitting compresses one side of the pelvis and is a leading driver of SI joint pain.
Truck & route drivers
Hours of seated vibration with the pelvis tilted toward the pedals, then heavy lifting at the dock. Truckers and delivery route drivers are a classic SI joint demographic in our clinic.
Auto accident patients
The sudden force of a car accident can jam or destabilize a sacroiliac joint, sometimes overshadowed by neck and back complaints at first. We evaluate the whole pelvis after a collision.
After a fall
A slip on ice or a fall directly onto the buttock or tailbone is a frequent trigger. The impact drives one side of the pelvis out of its normal position and sets off one-sided pain.
Warehouse & distribution workers
The Amazon, Walmart, and Schnucks hubs around North County run on repeated lift, twist, and lower cycles. Twisting under load is hard on the SI joints as well as the lumbar discs.
Runners & weekend warriors
Repetitive one-sided impact from running, plus weekend rounds of golf, gardening, or pickup sports after a sedentary week, can overload a pelvis that is not used to the demand.
Patients after lumbar fusion
When a segment of the lower spine is fused, the SI joints below take on extra motion and load. This is a well-recognized cause of new one-sided pain in fusion patients.
If your SI joint pain followed a car accident or is work-related, Dr. JC can help document the injury and coordinate with your auto-injury or workers' compensation carrier. We see patients from Bridgeton, Maryland Heights, Hazelwood, Florissant, St. Ann, Creve Coeur, and across North County St. Louis.
Frequently Asked Questions
SI joint dysfunction refers to pain that comes from abnormal motion or inflammation in the sacroiliac joints, the two joints that connect the base of your spine (the sacrum) to the pelvis. These joints are not built to move much, so when one becomes too stiff or moves too freely, it can produce a deep, one-sided ache low in the back or in the buttock. It is a mechanical problem with the joint itself, not a problem with the nerve or the disc.
They overlap, which is exactly why SI joint dysfunction is so often missed. Sciatica is nerve pain that shoots well past the knee and is usually driven by a compressed nerve root in the lumbar spine. SI joint pain tends to stay low on one side of the back or in the buttock and may refer into the hip or groin, but rarely travels below the knee. True hip pain is usually felt deeper in the groin and worsens with rotation. Dr. JC uses specific orthopedic tests during the exam to tell these apart, since each one responds to a different treatment approach.
Common drivers include pregnancy and the postpartum period, when hormones loosen the pelvic ligaments and the joint becomes less stable; prolonged sitting in desk workers and drivers; a fall onto the buttock or tailbone; and the impact of a car accident. Leg-length differences, repetitive one-sided loading, and previous lumbar fusion can also overload the joint. In many patients it is simply a buildup of these factors over time rather than one single event.
Chiropractic care addresses the mechanical cause directly. Specific adjustments restore normal motion to a sacroiliac joint that has become stuck or misaligned, which relieves the irritation and inflammation that produce the pain. Soft-tissue work releases the surrounding gluteal and hip muscles that tighten in response to the dysfunction, and targeted stabilization exercises retrain the pelvis to hold its position. This combination relieves current symptoms while reducing the chance the joint slips back into the same pattern.
Most SI joint dysfunction is managed with conservative care and does not require surgery. Surgical fusion of the joint is reserved for a small number of cases that have not responded to months of appropriate non-surgical treatment. For coverage, we work with BCBS, Aetna, Cigna, UnitedHealthcare, and Medicare. Coverage varies by policy, so call (636) 393-8390 to verify your plan's benefits before your first visit.
Many patients notice meaningful relief within the first few visits as normal joint motion is restored, with most cases settling over a four-to-eight-week course of care depending on how long the problem has been present and what is driving it. Acute flare-ups, such as a recent fall, often respond faster, while long-standing dysfunction tied to posture or pregnancy may take longer and relies heavily on consistent home stabilization work.
SI joint pain is a common complaint during pregnancy and the postpartum period, because the same hormones that prepare the pelvis for delivery also loosen the SI ligaments. If you are pregnant, check with your obstetric clinician before starting care. Positioning and techniques are adapted to your stage of pregnancy, and new or worsening symptoms should go to your obstetric clinician.
Yes. A fall or a car accident is a frequent trigger for SI joint dysfunction, and we see patients from Bridgeton, Maryland Heights, Hazelwood, Florissant, and across North County St. Louis for exactly this. If your pain followed a collision, Dr. JC can evaluate the pelvis and lumbar spine, document the injury, and coordinate with your auto-injury or workers' compensation carrier where applicable.
