What Is Shockwave Therapy (ESWT)?
Extracorporeal Shockwave Therapy (ESWT) uses a specialized device to deliver controlled, high-energy acoustic pressure waves to targeted areas of injured or degenerated soft tissue. "Extracorporeal" means the treatment is delivered from outside the body — no needles, no incisions, no surgery.
The shockwaves create a controlled mechanical stimulus that triggers a cascade of biological responses: increased blood flow, stimulation of collagen synthesis, activation of stem cells, and breakdown of calcific deposits. This effectively "restarts" the healing process in tissue that has entered a chronic, non-healing state.
Who is shockwave therapy for? Shockwave is most effective for chronic conditions — typically defined as symptoms lasting more than 3 months — that have not adequately responded to rest, stretching, physical therapy, or other conservative treatments. It is an excellent alternative to corticosteroid injections or surgery for appropriate candidates.
Conditions Treated with Shockwave Therapy at Pittsburgh Physical Medicine
- Plantar fasciitis — chronic heel and arch pain; one of the most evidence-supported applications of ESWT
- Calcific tendinitis of the shoulder — calcium deposits in the rotator cuff tendons; shockwave breaks down the calcium
- Achilles tendinopathy — chronic midportion or insertional Achilles pain common in runners and active adults
- Patellar tendinopathy ("jumper's knee") — chronic anterior knee pain from patellar tendon degeneration
- Lateral epicondylosis ("tennis elbow") — chronic lateral forearm and elbow pain from extensor tendon degeneration
- Greater trochanteric pain syndrome (hip bursitis) — lateral hip pain from gluteal tendinopathy
- Hamstring tendinopathy — proximal hamstring insertion pain at the ischial tuberosity
- Chronic low back myofascial pain — trigger point-driven lumbar pain that has not responded to other treatment
What to Expect During Shockwave Treatment
A shockwave session at Pittsburgh Physical Medicine typically lasts 15–20 minutes. The provider applies a coupling gel to the treatment area and uses the shockwave applicator to deliver 1,500–3,000 impulses at a frequency and intensity calibrated to your specific condition.
Some discomfort during treatment is normal, particularly over the most affected area. Most patients tolerate the treatment well. Mild soreness in the 24–48 hours following treatment is common and expected. Most conditions require 3–5 sessions spaced one week apart. Many patients notice improvement after the second or third session — though full benefit is typically realized 6–12 weeks after the final session as tissue remodeling completes.
