Shockwave Therapy: What You Need To Know

If you have been living with persistent pain that is not improving with rest, stretching, or other conservative treatments, you may have heard about shockwave therapy. This non-invasive treatment has become increasingly popular for managing a variety of musculoskeletal conditions, particularly those involving chronic tendon pain and soft tissue injuries.

Despite its growing popularity, many people are unsure what shockwave therapy actually is. The name alone can sound intimidating, leading some patients to believe the treatment involves electrical shocks or a painful procedure. In reality, shockwave therapy uses high-energy sound waves to stimulate the body’s natural healing response. Treatments are quick, require no surgery or injections, and can often be incorporated into a broader rehabilitation program.

At our physiotherapy clinic in Scarborough, shockwave therapy is one of the several evidence-based treatment options we may recommend to reduce pain, improve mobility, and support recovery. Here is what you should know before deciding whether it is right for you.

What Is Shockwave Therapy?

Patients are often surprised to learn that shockwave therapy has nothing to do with electricity. In this context, the word “shockwave” refers to high-energy acoustic (sound) waves that are delivered to an injured area using a handheld device.

During treatment, these sound waves pass through the skin and into the affected tissues without requiring needles or surgery. The treatment is designed to stimulate the body’s natural healing processes while helping reduce pain associated with chronic musculoskeletal conditions.

Shockwave therapy is commonly used when symptoms have persisted for several weeks or months and have not responded sufficiently to other conservative treatments. It is frequently combined with physiotherapy and exercise therapy rather than used as a standalone solution.

Although some people experience mild discomfort while the treatment is being applied, most patients tolerate it well. Sessions are relatively short, usually lasting between five and ten minutes depending on the size and location of the area being treated.

How Does Shockwave Therapy Work?

Shockwave therapy works by stimulating the body’s own repair mechanisms rather than masking symptoms alone. The acoustic waves create controlled mechanical stimulation within the affected tissue. This encourages increased metabolic activity, improves local circulation, and stimulates cells involved in tissue repair.

Shock waves mainly stimulate two types of cells: fibroblasts and osteoblasts. 

• Fibroblasts play an essential role in repairing connective tissues such as tendons, ligaments, fascia, and cartilage. When stimulated, these cells help produce collagen, an important structural protein that supports healthy tissue healing.
• Osteoblasts are responsible for forming new bone tissue and repairing damaged bone. Although shockwave therapy is more commonly associated with tendon injuries, stimulating these cells may also contribute to healing in certain bone-related conditions.

In addition to promoting tissue repair, shockwave therapy can influence the nervous system. Chronic pain often causes nerve endings to become highly sensitive, making everyday movements uncomfortable. Shockwave therapy helps reduce this heightened sensitivity by temporarily altering how pain signals are transmitted, allowing many patients to experience meaningful pain relief while rehabilitation continues.

Rather than simply covering up symptoms, the goal is to encourage healing while improving the body’s ability to function.

What Conditions Can Shockwave Therapy Help Treat?

Shockwave therapy is commonly used to treat a variety of chronic musculoskeletal conditions, particularly those involving tendons and other soft tissues.

Some of the conditions that may benefit include:

• Plantar fasciitis
• Achilles tendinopathy
• Muscle tightness and trigger points
• Chronic pain, especially in the neck or shoulder
• Tennis elbow (lateral epicondylitis)
• Golfer’s elbow
• Patellar tendinopathy (jumper’s knee)
• Rotator cuff tendinopathy
• Calcific shoulder tendinitis
• Hip pain involving the gluteal tendons

These conditions often develop gradually through repetitive movements, overuse, or prolonged strain. When symptoms persist despite rest or other conservative treatments, shockwave therapy may be recommended as part of a comprehensive rehabilitation program.

Your physiotherapist will determine whether your specific condition is appropriate for shockwave therapy after completing a thorough assessment.

What Happens During a Shockwave Therapy Session?

Many patients are unsure what to expect before their first appointment. At HealthMax, treatment begins with an assessment to determine whether shockwave therapy is appropriate for your condition. Your healthcare provider will identify the area causing your symptoms and discuss your treatment goals before beginning.

A small amount of ultrasound gel is applied to the skin to help transmit the acoustic waves. The handheld treatment device is then placed over the affected area, delivering a series of controlled sound waves into the tissues. You may feel tapping sensations or mild discomfort, particularly if the area is very sensitive. However, most patients tolerate the treatment well, and the intensity can often be adjusted to improve comfort while maintaining effectiveness.

Because each session typically lasts only five to ten minutes, many patients are able to return to work or their normal daily activities shortly afterward.

How Many Treatments Will I Need?

The number of treatments varies depending on your diagnosis, how long you’ve been experiencing symptoms, and how your body responds to therapy. Many patients begin noticing improvements after two or three sessions, although some chronic conditions require additional treatments.

Shockwave therapy is usually performed once per week, allowing the tissues time to respond between appointments. Your physiotherapist will monitor your progress throughout treatment and adjust your rehabilitation plan as your symptoms improve.

It’s important to remember that healing takes time. While some people notice early pain relief, the biological healing processes stimulated by shockwave therapy continue long after each treatment session.

Is Shockwave Therapy Effective?

Research has shown that shockwave therapy can be an effective treatment option for several chronic tendon and soft tissue conditions, particularly when combined with an individualized rehabilitation program.

Many patients report meaningful reductions in pain, improved mobility, and an increased ability to participate in everyday activities after completing treatment. For chronic conditions that have not responded well to rest alone, shockwave therapy may help restart the body’s healing response and support long-term recovery.

However, results vary from person to person. Factors such as the type of injury, how long symptoms have been present, your overall health, and your commitment to rehabilitation exercises can all influence your outcome.

Is Shockwave Therapy Right for Everyone?

Although shockwave therapy is safe for many people, it is not appropriate in every situation. Your healthcare provider may recommend another treatment approach if you are pregnant, have certain bleeding disorders, have an active infection near the treatment area, or have other medical conditions that make shockwave therapy unsuitable. It is also generally avoided over areas with open wounds or certain implanted medical devices, depending on their location.

This is why a professional assessment is an important first step. Determining the underlying cause of your pain allows your physiotherapist to recommend the treatment option that is most appropriate for your condition and recovery goals.

Living with ongoing pain can make work, exercise, and everyday activities more difficult than they should be. If your symptoms are not improving or continue to return, it may be time to explore additional treatment options. Shockwave therapy may provide the relief you need while supporting your body’s natural healing process. When combined with a comprehensive rehabilitation program, it can help reduce pain, improve movement, and support long-term recovery.

At our Scarborough Physiotherapy Clinic, we believe successful rehabilitation begins with understanding the source of your pain, not simply treating the symptoms.
