Sacroiliac joint dysfunction often presents as “just low back pain.” Your patient points to one side of the pelvis, reports pain with transitions or prolonged sitting, and may describe symptoms that travel into the buttock, hip, groin, or posterior thigh.
The lumbar spine may receive the attention. The SI joint complex may remain untreated.
For chiropractors, this creates a practical opportunity: combine precise examination, chiropractic adjustments, targeted rehabilitation, and high-intensity shockwave therapy to address the joint mechanics and the stressed soft tissues around them.
JointWave™ delivers powerful acoustic energy into soft tissue, joints, and tendons. Used as part of a complete care plan, this non-invasive pain therapy can help your practice address chronic pain while creating a structured, cash-based chiropractic service.
Clinical note: Direct research on ESWT specifically for SI joint dysfunction and sacroiliac ligaments remains limited. The protocol below represents a conservative, clinically reasoned framework that should be adapted to patient presentation, device training, local regulations, and professional judgment.
Better Diagnosis. Better Targeting. Better Outcomes.
What SI joint dysfunction really involves
The sacroiliac joint transfers load between the spine and lower extremities. It contributes to stability during walking, bending, lifting, running, and single-leg loading.
The joint itself represents only part of the pain generator. The posterior SI ligament complex, sacrotuberous and sacrospinous ligaments, thoracolumbar fascia, gluteal muscles, piriformis, and hip stabilizers all influence pelvic load transfer.
That is why SI joint dysfunction can involve:
- Joint hypomobility or stiffness
- Excessive motion or reduced pelvic stability
- Ligament strain or enthesopathy
- Myofascial guarding
- Repetitive shear from sports, lifting, gait changes, pregnancy, or prior lumbar surgery
- Hip and lumbar movement dysfunction
The American Academy of Family Physicians notes that estimates of SI joint involvement in low back pain vary across reviews, with commonly cited ranges spanning roughly 10% to 38% of presentations.
The clinical message is simple: not every patient with low back pain has a lumbar spine problem.
Find the Pattern. Confirm the Source. Rule Out Red Flags.
Diagnostic clues your clinic can use
Patients with SI joint-related pain commonly describe:
- Pain below the belt line, often just inferomedial to the posterior superior iliac spine
- Unilateral or bilateral buttock pain that usually does not remain midline
- Referred pain into the posterior thigh, groin, lateral hip, or occasionally below the knee
- Pain when sitting for long periods or standing asymmetrically
- Difficulty with sit-to-stand transitions
- Pain while climbing stairs, turning in bed, walking uphill, or loading one leg
- A dull ache with sharper pain during twisting, lifting, or transitional movements
- Muscle guarding around the gluteal, lumbar, and pelvic regions
Use a complete history and examination. The Fortin finger test can help identify whether the patient points to the characteristic SI region. Assess gait, hip range of motion, pelvic control, gluteal strength, lumbar movement, and neurologic status.
A cluster of provocation tests improves diagnostic confidence. Consider:
- Thigh thrust
- Gaenslen
- Sacral thrust
- Distraction
- Compression
When multiple provocation tests reproduce the patient’s familiar pain, diagnostic confidence for SI joint dysfunction increases. A diagnostic block may help confirm the SI joint as the pain generator when referral or interventional care becomes necessary.
Screen for red flags before treatment. Refer or coordinate care when the presentation suggests fracture, infection, malignancy, inflammatory spondyloarthropathy, progressive neurologic deficit, bowel or bladder changes, unexplained weight loss, fever, significant trauma, or severe night pain.
Adjust the Joint. Rebuild the Support.
Why adjustments alone may not be enough
An adjustment can improve joint motion and reduce mechanical restriction. It does not automatically restore the capacity of irritated ligaments, scarred fascia, or inhibited stabilizing muscles.
A patient may feel better immediately after an adjustment but continue to overload the same tissues during walking, lifting, or standing. When the soft-tissue support system remains painful or poorly conditioned, the improvement may not hold.
That is where a multimodal plan becomes valuable:
✅ Adjustments address joint mechanics and motion restrictions.
✅ JointWave therapy targets painful soft-tissue structures and surrounding musculature.
✅ Rehabilitation improves pelvic control, strength, and load tolerance.
✅ Patient education reduces repeated aggravating behaviors.
The AAFP recommends combining manipulative therapy with pelvic girdle stabilization, focused stretching, and strengthening. JointWave should complement, not replace, those foundational interventions.
Deliver Acoustic Energy. Stimulate Recovery. Reduce Irritation.
How high-intensity shockwave therapy may help
High-intensity shockwave therapy uses acoustic energy to create a mechanical stimulus within targeted tissue. Depending on the treatment site and parameters, proposed effects include:
- Temporary modulation of pain signaling
- Increased local circulation and vascular response
- Support for tissue remodeling
- Stimulation of cellular activity involved in repair
- Reduction of chronic soft-tissue sensitivity and guarding
- Improved tolerance for progressive movement and rehabilitation
For SI presentations, your target is usually not the deepest portion of the joint itself. You are addressing the posterior SI ligament complex, periarticular tissues, entheses, gluteal muscles, piriformis, and thoracolumbar fascia that contribute to the patient’s pain pattern.
Because SIJ-specific ESWT evidence remains limited, explain the treatment accurately. Present JointWave as a non-invasive adjunct within a broader care plan, not as a guaranteed cure or replacement for diagnostic workup.
Start Conservatively. Progress Intentionally. Reassess Objectively.
An example SI-focused JointWave protocol
The following framework is an example starting protocol, not a validated SI-specific prescription. Use your JointWave training, device instructions, patient response, and clinical judgment to determine final settings.
Session 1: Baseline and tissue tolerance
- Document pain location, pain intensity, gait, sitting tolerance, transitional pain, and relevant functional goals.
- Perform the SI provocation cluster and identify the most reproducible tender points.
- Begin with low-to-moderate energy and a comfortable frequency.
- Use coupling medium as directed by your device training.
- Treat the most symptomatic posterior SI ligament and periarticular soft-tissue points.
- Add light treatment to guarding in the gluteus maximus, gluteus medius, piriformis, or thoracolumbar fascia when clinically appropriate.
- Avoid aggressive treatment directly over the sacral foramina, acute bruising, open skin, or areas where deeper structures cannot be safely assessed.
A practical starting point may use approximately 2,000 pulses at 8–12 Hz with energy increased gradually according to tolerance. The JointWave interface shown in the clinic imagery displays settings such as energy, frequency, and presets; your trained provider should select the appropriate combination for the patient and applicator.
Sessions 2–3: Build consistency
Schedule treatments approximately 5–10 days apart, depending on symptoms and recovery response.
At each visit:
- Recheck the patient’s familiar pain and functional limitation.
- Reassess the primary ligamentous or myofascial target.
- Repeat or modestly progress the energy only if the prior response remained favorable.
- Treat the symptomatic side first, then address associated muscle guarding.
- Follow treatment with controlled mobility and stabilization exercises.
Do not chase pain with excessive energy. Mild, temporary tenderness can occur, but a significant flare should prompt a reduction in intensity, a longer interval, or a reassessment of the diagnosis.
Sessions 4–5: Reinforce function
Many practices can begin with 3–5 total sessions, then reassess. Continue only when the patient demonstrates measurable progress in pain, walking, sitting, lifting, sleep, or other agreed-upon goals.
Combine each visit with:
- Appropriate SI or lumbar adjustment
- Hip mobility work
- Gluteus medius and gluteus maximus strengthening
- Transverse abdominis and pelvic-floor activation when indicated
- Hamstring, iliopsoas, piriformis, or thoracolumbar mobility work
- Gradual single-leg loading and functional retraining
You can use JointWave before an adjustment when muscle guarding limits positioning. You can also use it after the adjustment to address the surrounding soft tissue while the patient moves through improved mechanics. Choose the workflow that best fits your examination findings and clinic schedule.
Measure Progress. Set Expectations. Protect Patient Trust.
Expected timelines and outcomes
Some patients report an immediate change in tenderness or movement tolerance. Others improve gradually over several weeks as the acoustic stimulus, manual care, and rehabilitation work together.
Set functional expectations instead of promising a specific pain score:
- Easier sit-to-stand transitions
- Longer sitting or standing tolerance
- Less pain during stairs or walking
- Improved single-leg control
- Reduced tenderness near the PSIS
- Fewer flare-ups during daily activity
- Better tolerance for strengthening and movement
Reassess after each session and at the end of the initial series. If the patient shows no meaningful change, reconsider the diagnosis and screen for lumbar, hip, neurologic, inflammatory, or visceral contributors.
Patient selection and contraindications
JointWave may fit patients with chronic, localized SI-region pain and a reproducible soft-tissue component who understand the limits of current evidence.
Use caution or defer treatment for patients with:
- Pregnancy when treating near the pelvis
- Active infection or open wounds
- Suspected malignancy
- Acute fracture or significant recent trauma
- Significant bleeding disorder or anticoagulation concerns
- Open growth plates
- Severe osteoporosis
- Unclear diagnosis or progressive neurologic symptoms
- Pain patterns suggesting visceral, inflammatory, or serious spinal disease
Always follow the device’s indications, contraindications, and safety instructions. Refer when the presentation exceeds your clinic’s scope.
