Pain beyond 12 weeks
Chronic low back pain
Persistent pain with no single structural cause, usually defined as lasting longer than three months. Most pooled trial data comes from this group.
Service · Alpharetta, Georgia
Short pressure pulses, delivered through the skin, for persistent low back pain. Clinical trials point to short-term pain relief, strongest when treatment is paired with active rehabilitation.
Also called extracorporeal shockwave therapy (ESWT) or shockwave therapy
How it works
Acoustic wave therapy sends short, controlled pressure pulses through the skin and into tight, irritated or slow-healing tissue. It is also called extracorporeal shockwave therapy, or ESWT. The pulses are mechanical, so treatment involves no needle, drug or incision.
Laboratory and clinical studies suggest the pulses affect local blood flow, inflammation and pain signaling. How much each of these matters for low back pain in people is still being studied.
Your visit
We review your history, examination findings and any imaging to confirm the source of pain and whether you are a candidate.
You rest comfortably while gel is applied over the treatment area.
Your doctor or a trained member of our clinical team moves the applicator over the area and delivers the pulses. Intensity is set to what you can tolerate.
Before you leave we set your follow-up schedule, along with any exercises or other care that go with it.
Who it is studied in
Published trials have enrolled people with these patterns of pain. An exam decides whether any of them matches yours.
Pain beyond 12 weeks
Persistent pain with no single structural cause, usually defined as lasting longer than three months. Most pooled trial data comes from this group.
Sham-controlled trial
Pain near the base of the spine where the pelvis meets the sacrum, including pain after pregnancy and delivery.
Sham-controlled trial, 2025
Pain from the small joints along the back of the spine, studied with a high-energy focused device.
Compared with injection
Tight muscle knots in the low back, such as in the quadratus lumborum, and buttock pain from piriformis syndrome.
Some causes of back pain, including fracture, infection and nerve compression that needs urgent care, call for a different approach. We rule these out first.
The research
Pooled analyses of randomized trials found less pain in the short term with shockwave than with sham or comparison care. Results for function were less consistent when it was used alone, and the overall certainty of the evidence is low to very low.
| Review | Evidence base | Main finding |
|---|---|---|
| Yue et al., 2021BioMed Research International | 10 randomized trials, 455 patients | Lower pain at 1 month (SMD −0.81) and lower disability at 1 and 3 months. No serious shockwave-related adverse events. |
| Liu et al., 2023Journal of Orthopaedic Surgery and Research | 12 randomized trials, 632 patients | About 1 point more pain relief than controls at 4 weeks (WMD −1.04) and better lumbar function. No serious adverse effects. No significant change in mental health. |
| Wu et al., 2023Medicine | 22 studies, 1,749 patients | Better pain, function and psychological outcomes than other therapies. Sensitivity analyses were stable. The authors call for larger trials with more objective outcomes. |
| Ferdinandov, 2024Frontiers in Medicine | Systematic review of focused-wave trials | Critical review of focused devices, which concentrate energy at a set depth, for low back pain. |
| Qiao et al., 2026Frontiers in Physiology | 14 randomized trials, 738 patients (network meta-analysis) | Shockwave beat sham for pain (SMD −1.22). Shockwave plus physical therapy beat physical therapy alone for pain (SMD −0.88) and disability (about 5 points). Shockwave alone showed no clear disability benefit. |
Safety
No serious treatment-related adverse events appeared in the pooled analyses of randomized trials. Temporary soreness, redness or mild bruising at the treatment site are commonly described after shockwave treatment.
Treatment over the lower spine is not suitable for everyone, which is why the evaluation comes first.
Your plan
The strongest results in the 2026 analysis came from pairing shockwave with conventional physical therapy. At North Atlanta Spine, acoustic wave therapy sits alongside our other services, so your plan can combine treatments that fit your diagnosis.
Questions
Yes. Acoustic wave therapy, shockwave therapy and extracorporeal shockwave therapy (ESWT) describe the same family of treatments. Devices differ in how energy is delivered, either radial or focused, and your provider will explain which approach suits your condition.
You will feel rhythmic tapping and pressure. Irritated areas can be tender. Intensity is set to what you can tolerate, and you can ask to pause or turn it down at any point.
In the published low back trials, courses ran from a single session up to 6 weeks, usually with one or two visits per week. Your plan depends on your exam findings and how you respond.
Studies typically measured results at about 4 weeks to 3 months. Some people notice a change sooner, others need the full course, and some do not respond.
Coverage varies by plan and by diagnosis. Ask our team before you start and we will explain your options.
Yes. In the 2026 analysis, shockwave paired with conventional physical therapy gave better pain and function results than physical therapy alone. Your provider will build a plan around your diagnosis.
A short evaluation will show whether you are a candidate and what a course of care would involve.
