Shockwave therapy is used to treat a wide range of musculoskeletal conditions, from chronic heel pain and tendon injuries to non-healing bone fractures. It also has established applications in urology and wound care. The treatment works by delivering pulses of pressure energy into damaged tissue, triggering the body’s own repair processes. Originally developed to break up kidney stones in the 1980s, it has since expanded into orthopedics, sports medicine, and several other fields.
How Shockwave Therapy Works
The treatment delivers acoustic pressure waves through the skin and into the target tissue. These pulses create controlled microtrauma at the cellular level, which sets off a cascade of biological responses. The body responds by forming new blood vessels in the treated area, a process called neovascularization. It also releases growth factors that stimulate tissue repair, boost collagen production, and recruit stem cells to the site of injury. For conditions involving calcium deposits, the pressure waves can fragment and break down those deposits from within.
Pain relief appears to come from two directions. The new blood supply and tissue regeneration address the underlying problem, while the shockwaves also have a direct suppressive effect on pain receptors in the area. This combination of structural healing and nerve-level pain reduction is part of why the therapy works for such a variety of conditions.
Focused vs. Radial Shockwaves
There are two main types of shockwave devices, and they work differently. Focused shockwave therapy produces a concentrated beam that converges at an adjustable depth inside the body. This makes it well suited for reaching deeper structures like bone, joint cartilage, or deep tendons. Radial shockwave therapy, by contrast, delivers its maximum pressure at the skin surface and disperses as it travels deeper. That makes it more effective for superficial muscles and tendons closer to the surface. Your practitioner will choose the type based on the location and depth of the problem being treated.
Plantar Fasciitis and Heel Pain
Chronic plantar fasciitis is one of the most common and well-studied uses for shockwave therapy. It’s typically offered after conservative treatments like stretching, orthotics, and physical therapy have failed to resolve symptoms over several months. In a retrospective study of 78 heels treated with radial shockwave therapy, success rates (defined as more than 60% pain reduction) climbed steadily over time: 19% at one month, 70% at three months, and 98% at one year. The recurrence rate at one year was just 8%.
Patients in that study received an average of seven sessions, performed once per week. Those who had experienced pain for longer than three months were typically recommended six to eight sessions rather than the standard four to six. The pressure level is adjusted based on pain tolerance during each session.
Tendon Injuries and Calcifications
Shockwave therapy is widely used for chronic tendon problems, particularly when calcium deposits have formed. Calcific tendonitis of the rotator cuff is a classic example. A study published in JAMA found that high-energy shockwave therapy produced significant benefits over sham treatment at six months. Long-term follow-up at four years showed no tendon damage or lasting side effects from the procedure.
Beyond calcific tendonitis, the therapy is used for a range of tendon conditions including Achilles tendinopathy, tennis elbow, and jumper’s knee. The shockwaves stimulate the release of growth factors that increase collagen production in tendon cells, essentially restarting a healing process that had stalled. The formation of new blood vessels at the tendon-bone junction appears to be a key part of this repair.
Non-Healing Bone Fractures
When a broken bone fails to heal on its own, a condition called nonunion, shockwave therapy offers a noninvasive alternative to surgery. A systematic review covering 1,200 long bone nonunions found that 73% healed after shockwave treatment. Results varied by location: metatarsal bones (in the foot) had the highest healing rate at 90%, followed by the tibia (shin bone) at 76%, the femur (thigh bone) at 67%, and the upper arm bone at 64%.
Two factors significantly influenced outcomes. Fractures treated sooner after injury healed at higher rates than those where treatment was delayed. And somewhat counterintuitively, lower energy settings produced better results than higher ones. For example, femurs treated at lower energy densities healed 93% of the time, while those treated at higher intensities healed only 52 to 75% of the time. Healing also continued well beyond the treatment period, with rates still improving at follow-ups past six months.
Erectile Dysfunction
Low-intensity shockwave therapy has emerged as a treatment for erectile dysfunction, particularly in men whose condition stems from reduced blood flow. The mechanism is essentially the same as in other tissues: the shockwaves create microtrauma that triggers new blood vessel growth in penile tissue. A typical protocol involves six sessions delivered twice weekly over three consecutive weeks, with 3,000 shockwaves applied per session across multiple treatment areas.
The therapy targets the root vascular problem rather than simply managing symptoms the way oral medications do. However, research on long-term durability is still developing, and it is not yet considered a first-line treatment by most urology guidelines.
Peyronie’s Disease
For Peyronie’s disease, a condition where scar tissue (plaque) forms inside the penis causing curvature and pain, shockwave therapy is primarily effective for pain relief. In one study, 64% of patients achieved significant pain reduction or complete resolution after treatment. The effect was more pronounced in patients whose plaques were not calcified. Plaque size reduction was more modest, with only 20% of patients seeing a greater than 50% decrease in plaque size, though the overall reduction in plaque dimensions was statistically significant.
Chronic Wounds and Diabetic Ulcers
Shockwave therapy has shown promise for chronic wounds that resist standard treatment, particularly diabetic foot ulcers. In a randomized controlled trial, ulcers treated with shockwave therapy healed significantly faster than those receiving standard wound care alone. The average healing time was about 65 days in the shockwave group versus 81 days in the control group. Complete healing was achieved in 54% of shockwave-treated ulcers by 20 weeks, compared to 29% in the control group. No adverse reactions were reported.
The therapy works here by stimulating blood vessel growth and tissue regeneration in wound beds that have essentially stopped healing on their own. It is used as an add-on to standard wound care, not a replacement for it.
What Treatment Looks Like
A typical course of shockwave therapy involves three to five sessions spaced about one week apart. Bone-related conditions and certain other applications may require different scheduling. Each session is relatively brief, usually lasting 10 to 20 minutes depending on the condition and area being treated. A handheld device is pressed against the skin over the affected area, and you’ll feel rapid tapping or pulsing sensations that can range from mildly uncomfortable to moderately painful, depending on the energy level and your sensitivity.
No anesthesia is typically required, though practitioners adjust the pressure based on what you can tolerate during the session. Most people return to normal activities the same day, though some soreness or mild swelling in the treated area is common for a day or two afterward.
Safety and Limitations
Shockwave therapy is generally considered safe when performed appropriately. The most common side effects are temporary: redness, swelling, bruising, or soreness at the treatment site. Serious complications are rare. The main contraindications include blood clotting disorders (for high-energy treatments), pregnancy when the treatment area is near the fetus, and severe infection in the target area. Practitioners must also ensure the lungs are not in the path of the shockwaves, as this could cause tears, bleeding, or a collapsed lung.
The therapy works best for chronic conditions that haven’t responded to more conservative approaches. It is not a first-line treatment for acute injuries, and results are not immediate. Improvement typically builds over weeks to months as the biological healing processes take effect.
