The Origin of Shockwave Therapy

Shockwave therapy has been used in medicine for decades.

It first became widely known for treating kidney stones using high-energy shockwaves. These shockwaves were able to break stones into smaller fragments without surgery, allowing them to pass naturally through the urinary system.

This procedure is known as Extracorporeal Shock Wave Lithotripsy (ESWL).

As researchers continued studying shockwaves, they began exploring whether lower-intensity shockwaves could be used for other medical purposes beyond kidney stones.

Over time, shockwave therapy expanded into orthopedic and sports medicine applications.

Why Is Shockwave Therapy Used Today?

Today, shockwave therapy is commonly used as a non-invasive treatment intended to help:

• Reduce pain
• Stimulate healing responses
• Improve tissue recovery

Because of these potential effects, it has become increasingly popular in rehabilitation settings, particularly for chronic and repetitive overuse injuries.

But what actually happens inside the tissue when shockwave therapy is applied?

The 3 Phases of Shockwave Therapy

Current research suggests that shockwave therapy may influence tissue through several interconnected phases.

1. Physical Phase

The device generates a rapid pressure wave that travels through tissue.

This creates mechanical stimulation within the treatment area, including:

• Compression forces
• Shear stress
• Pressure fluctuations
• Mechanical vibration within tissue

These mechanical effects are believed to be the first step in initiating tissue responses.

2. Chemical Phase

The mechanical stimulation may trigger a process called mechanotransduction.

Mechanotransduction refers to the ability of cells to convert mechanical forces into biochemical signals.

In other words, tissue doesn’t simply experience pressure physically—cells may also respond biologically to that stimulus.

Research has explored potential effects on:

• Cellular communication
• Release of signaling molecules
• Inflammatory activity
• Healing-related pathways
• Tissue adaptation responses

This is one reason shockwave therapy has gained significant attention in rehabilitation and sports medicine research.

3. Biological Phase

Over time, these chemical signals may contribute to broader biological responses.

Research has explored possible effects related to:

• Angiogenesis (new blood vessel formation)
• Inflammation modulation
• Tissue regeneration pathways
• Pain modulation and healing responses

While the exact mechanisms continue to be investigated, researchers believe these biological responses may help explain some of the clinical improvements observed in certain conditions.

Conditions Commonly Treated With Shockwave Therapy

Current evidence is strongest for several musculoskeletal conditions, particularly chronic tendon-related disorders.

Common applications include:

• Plantar fasciitis
• Tennis elbow (lateral epicondylalgia)
• Golfer’s elbow
• Achilles tendinopathy
• Patellar tendinopathy (jumper’s knee)
• Rotator cuff tendinopathy
• Calcific shoulder tendinitis
• Gluteal tendinopathy
• Hamstring tendinopathy
• Chronic myofascial pain

Emerging Areas of Research

Researchers are also exploring the use of shockwave therapy in other pain-related conditions, including:

• Chronic pelvic pain
• Chronic Prostatitis / Chronic Pelvic Pain Syndrome (CPPS)
• Dysmenorrhea (menstrual pain)

Although these areas show promise, the evidence is still developing and continues to evolve.
