Extracorporeal Shockwave Therapy (ESWT)

WhatsApp Order
Extracorporeal Shockwave Therapy (ESWT) is a non-invasive treatment modality that delivers acoustic shockwaves to tissues to stimulate healing, reduce pain, and improve function in chronic musculoskeletal conditions. Used for chronic tendinopathies including plantar fasciitis, Achilles tendinopathy, tennis elbow, and rotator cuff tendinopathy, as well as non-union fractures and myofascial pain, ESWT provides an effective non-surgical option for patients who have failed conservative treatment. Available in focused and radial forms, it offers hope for recovery without surgery.
Description

Extracorporeal Shockwave Therapy (ESWT)

PRIMARY CLINICAL & DIAGNOSTIC USES

1. Treatment of Chronic Tendinopathies
  • Primary Use: Delivers focused or radial shockwaves to treat chronic tendinopathies including plantar fasciitis, Achilles tendinopathy, patellar tendinopathy (jumper’s knee), lateral epicondylitis (tennis elbow), and rotator cuff tendinopathy. Shockwaves stimulate tissue healing, reduce pain, and promote neovascularization.
  • How it helps: For the orthopedic surgeon, sports medicine physician, and physical therapist, ESWT provides a non-invasive treatment option for chronic tendon conditions that have failed conservative management—stimulating healing and reducing pain without surgery. For the patient with chronic tendon pain that has not responded to rest, therapy, or injections, shockwave therapy offers hope for recovery without the risks of surgery.
2. Treatment of Plantar Fasciitis
  • Primary Use: One of the most common indications for ESWT, delivering focused shockwaves to the plantar fascia insertion to reduce pain, inflammation, and promote healing in patients with chronic plantar fasciitis unresponsive to conservative treatment.
  • How it helps: For the podiatrist and orthopedic foot and ankle specialist, ESWT provides an effective non-surgical option for patients suffering from chronic heel pain—reducing pain and improving function without the risks of surgery. For the patient with persistent plantar fasciitis who has tried stretching, orthotics, and injections without relief, shockwave therapy offers a path to pain-free walking.
3. Treatment of Calcific Rotator Cuff Tendinopathy
  • Primary Use: Focused shockwave therapy is used to fragment calcific deposits in the rotator cuff tendons, reducing pain and improving shoulder function. The shockwaves break down calcium deposits and stimulate tissue healing.
  • How it helps: For the orthopedic shoulder specialist, ESWT provides a non-invasive alternative to surgery for patients with painful calcific tendinopathy—breaking down calcific deposits and relieving pain without the need for arthroscopic debridement. For the patient with a painful calcified rotator cuff, shockwave therapy offers the possibility of pain relief without surgery.
4. Treatment of Non-Union Fractures and Delayed Union
  • Primary Use: Focused shockwave therapy is used to stimulate bone healing in patients with non-union fractures (fractures that have failed to heal) and delayed union. The mechanical stimulation promotes osteogenesis and revascularization at the fracture site.
  • How it helps: For the orthopedic trauma surgeon, ESWT provides a non-surgical option for stimulating bone healing in fractures that have failed to unite—potentially avoiding the need for bone grafting and revision surgery. For the patient with a fracture that has not healed after months of immobilization, shockwave therapy offers hope for bone healing without additional surgery.
5. Treatment of Myofascial Pain Syndrome and Trigger Points
  • Primary Use: Radial shockwave therapy is used to treat myofascial pain syndrome by delivering shockwaves to trigger points, reducing muscle tension, pain, and improving range of motion in conditions such as chronic neck pain, back pain, and muscle spasms.
  • How it helps: For the physical therapist and pain management specialist, ESWT provides a non-invasive tool for treating chronic myofascial pain—releasing trigger points and reducing muscle tension without needles or medication. For the patient with chronic muscle pain and tightness, shockwave therapy offers relief when other treatments have failed.

SECONDARY & SUPPORTIVE USES

1. Treatment of Chronic Wounds: ESWT used to stimulate healing in chronic wounds, diabetic foot ulcers, and pressure ulcers.
2. Treatment of Peyronie’s Disease: Focused shockwave therapy for treatment of penile plaques and curvature.
3. Treatment of Scars and Keloids: ESWT for improving scar appearance and reducing keloid formation.
4. Treatment of Peripheral Neuropathy: Shockwave therapy for neuropathic pain and nerve regeneration.
5. Treatment of Osteoarthritis: ESWT for knee and hip osteoarthritis to reduce pain and improve function.
6. Sports Injury Rehabilitation: Treatment of muscle strains, contusions, and other sports-related injuries.
