Shockwave Therapy (ESWT)
Acoustic pressure wave therapy that stimulates tissue repair, reduces pain, and accelerates healing for tendinopathies, musculoskeletal conditions, and erectile dysfunction
Bottom Line
Extracorporeal Shockwave Therapy (ESWT) uses focused acoustic pressure waves to stimulate tissue repair through mechanotransduction. Unlike vibroacoustic therapy (relaxation-focused), ESWT creates actual mechanical stress that triggers healing cascades.
The evidence is strong. Multiple 2024 systematic reviews confirm effectiveness for tendinopathies (plantar fasciitis, tennis elbow, Achilles), knee osteoarthritis, and erectile dysfunction. A 2024 RCT showed ESWT significantly outperformed ultrasound for lateral epicondylitis pain and grip strength.
Originally developed for kidney stones, ESWT is now FDA-cleared for multiple musculoskeletal indications. It's become standard treatment in sports medicine and physical therapy clinics worldwide.
One of the most evidence-backed recovery interventions available. If you have chronic tendon pain that hasn't responded to rest and PT, ESWT should be on your list. Clinical treatment is gold standard, but quality home devices can maintain benefits between sessions.
Science
Mechanisms:
- Mechanotransduction: Acoustic waves convert mechanical load into cellular responses
- Neovascularization: Stimulates new blood vessel formation in damaged tissue
- Cell proliferation: Triggers growth of tendon and bone cells
- Collagen synthesis: Promotes structural repair of damaged connective tissue
- Anti-inflammatory: Reduces inflammatory cytokines at treatment site
- Calcific resorption: Breaks down calcium deposits in tendons
- Pain modulation: Disrupts pain signaling pathways
Key Research:

Focused ESWT promotes bone growth for stress fracture healing
Dr. Fick explains how focused shockwave therapy causes bone hypertrophy visible on x-ray and MRI, making it a promising non-surgical treatment for bone stress injuries in runners.
"that the use of shockwave can be really effective in treating bone stress injuries because it causes bone growth or bone hypertrophy. And we've seen that on plain x-ray and we've seen the effects on the bone through MRI as well."
Case study of a grade 3 bone stress injury returning to competition in 3 weeks
A high school senior with a grade 3 posterior medial tibial bone stress injury returned to competitive running within three weeks using combined focused shockwave, radial shockwave, deep tissue laser, dry needling, and blood flow restriction training.
"After two weeks, he started running on the Alter-G treadmill. He started land running this past week and is going to be able to compete in the state cross-country meet when many people probably thought that would be impossible or a bad idea."
Booster shockwave treatments protect newly healed bone during return to running
Booster focused shockwave sessions during the return-to-run progression protect vulnerable newly healed bone through continued osteogenic stimulation, reducing the risk of re-injury.
"during this return to run progression, we know that this newly healed bone is vulnerable and we use the shockwave therapy for its bone building effects or osteogenic effects to ensure continued bone healing rather than the return of injury."
Meta-analysis of 17 RCTs shows shockwave improves rotator cuff pain and function
A 2024 systematic review of 17 randomized controlled trials with 1,131 patients found that extracorporeal shockwave therapy produced statistically significant improvements in pain and function for rotator cuff tendinopathy compared to rehabilitation alone.
"This is a systematic review and meta-analysis published in the May 2024 issue of BMC Musculoskeletal Disorders by Zhu et al."
Both radial and focused shockwave show improvement trends
Subgroup analysis dividing studies by intensity and type (radial vs focused) found trends toward improvement regardless of which modality was used, though more standardized research is needed.
"the subgroup analysis that they did in this article dividing the intensities and whether it was radial or focused found a trend towards improvement regardless of which intensity was used or whether it was radial or focused."
ESWT as a safe adjunct to rehabilitation for shoulder tendinopathy
Despite methodologic limitations, the meta-analysis concludes that shockwave is a safe treatment with a good safety profile that can serve as a useful adjunct to rehabilitation for rotator cuff tendinopathy.
"I would say that it might be a good adjunct to add to someone who's getting rehab for a rotator cuff tendinopathy."
Who is a good candidate for shockwave therapy
Good candidates for shockwave have chronic tendinopathy lasting 3+ months with low-level (1-2 out of 10), localized, stubborn pain that doesn't respond to progressive loading. Acute, highly sensitive, or widespread pain is not well-suited for ESWT.
"lateral hip, proximal hamstring tendinopathy. That's pretty much, and I do treat, might not be relevant for runners. I do treat a lot of groin patient on adductor tendon as well. So that might not be relevant for, so those are the areas where it's very reasonable to try shockwave, especially if they're filled with good quality rehab. Okay. So we're looking at those areas that you listed and we're looking for a kind of low level, achy, high functioning area."
85% pain reduction with shockwave vs 10% with conservative treatment
Research shows 85% of proximal hamstring tendinopathy patients experienced at least 50% pain reduction with ESWT compared to only 10% in a traditional conservative treatment group that included exercise.
"quite a significant group, I would say at least one in four or at least 20 to 30% of patients where despite good rehabilitation, they were still struggling with pain. Obviously, they had improvement. So this is sort of nine, 10 years ago. So I'm talking about patients with runners with Achilles tendon and lateral hip pain and peltier tendon. And many of them didn't want injections or PRP and things like that. So"
Combining shockwave with strength training yields the best outcomes
While shockwave provides effective short-term pain relief, strength training is vital for long-term tendon resilience. Combining both approaches produces the best patient outcomes for tendinopathies.
"evidence-based like real strength-based rehab programs. Is that right? Of course. Of course. We know that, you know, progressive loading shockwave, I keep it simple with my patients say shockwaves for pain relief and kickstart the healing. Whereas the function on the long-term recovery and also getting back into that full sport can only come from exercise and progressive loading. Shockwave is not going to make you stronger and it's not going to get you into the performance area as well. The two points I would like to pick up here is the,"
Origins of shockwave in sports medicine and the shift from OR to outpatient
Dr. Tenforde traces shockwave from lithotripsy in the 1980s to modern portable devices that can be used in outpatient clinics without anesthesia, explaining why this shift has made ESWT accessible and safe for sports medicine applications.
"So shockwave has been a concept in the general medicine world since the early 80s when it was used to treat kidney stones."
Radial pressure waves are not true shockwaves
Dr. Tenforde clarifies the scientific consensus that radial pressure waves are not true shockwaves and explains the three types of focused shockwave generators (electromagnetic, electrohydraulic, piezoelectric) and their different clinical applications.
"Our real understanding of the science is that the radial pressure waves are not a true shock wave. They're offered by a number of individuals, including non-physicians, and they don't create the same type of true shock wave that a focus device creates."
Focused shockwave treats bone pathologies beyond soft tissue
Dr. Tenforde explains how focused shockwave expands treatment to bone stress injuries, fractures, avascular necrosis, and joint conditions, with applications growing across cardiology, urology, neurology, and sexual health.
"but also to treat bone pathologies. So we can treat fractures, we can treat bone stress injuries, we can treat avascular necrosis, we can treat other joint conditions."
