Focused vs Radial Shockwave Therapy: What's the Difference and Why Does It Matter?
Shockwave therapy has become one of the most effective non-surgical treatments for chronic tendon pain and musculoskeletal injuries. If you've been researching shockwave therapy, however, you may have noticed that not all shockwave machines are the same.
The two most common types are Radial Shockwave Therapy (RSWT) and Focused Shockwave Therapy (FSWT).
At Physio Edge, we have invested in advanced FOCUS (Focused) Shockwave Technology because it allows us to deliver treatment with greater precision and depth. But what exactly is the difference?
What Is Shockwave Therapy?
Shockwave therapy uses high-energy acoustic waves to stimulate the body's natural healing response.
Research has shown shockwave therapy can be highly effective for conditions such as:
Plantar fasciitis
Achilles tendinopathy
Tennis elbow
Golfer's elbow
Patellar tendinopathy (jumper's knee)
Rotator cuff tendinopathy
Greater trochanteric pain syndrome (hip tendon pain)
Calcific shoulder tendinitis
The treatment works by stimulating blood flow, encouraging tissue regeneration, reducing pain sensitivity and promoting healing in chronic injuries that have often failed to respond to rest, stretching or traditional physiotherapy alone.
What Is RADIAL Shockwave Therapy?
Radial shockwave therapy is the type most commonly found in physiotherapy clinics.
A projectile inside the handpiece strikes a transmitter, creating pressure waves that spread outwards from the applicator.
Think of it like dropping a stone into a pond; the energy disperses as it travels (or think of it as a lighbulb rather that the laser focus of the FOCUS shockwave).
This makes radial shockwave particularly useful for:
More superficial conditions
Larger treatment areas
Generalised muscle tightness
Early-stage tendon problems
However, the energy is strongest at the skin surface and gradually loses intensity as it travels deeper into the body.
What Is FOCUS Shockwave Therapy?
Focused shockwave therapy uses a different technology.
Instead of dispersing energy from the surface, the machine concentrates energy at a specific depth within the tissue.
Think of it like using a magnifying glass to focus sunlight onto a single point.
This allows us to target deeper structures with significantly greater precision.
The result is:
More accurate treatment of injured tissues
Greater penetration depth
Higher energy delivery to the target tissue
Less energy wasted in surrounding structures
Why Is FOCUS Shockwave Considered Superior?
1. Greater Depth of Penetration
Many chronic tendon injuries are located several centimetres beneath the skin.
Focused shockwave can penetrate much deeper than radial shockwave, allowing treatment of structures that may otherwise be difficult to reach effectively.
This is particularly valuable for:
Deep gluteal tendinopathy
Hip tendon pain
Hamstring tendon injuries
Certain shoulder conditions
Achilles Tendonopathy
Tennis and Golfers’ Elbow
2. Greater Precision
Focused shockwave allows the clinician to concentrate treatment exactly where it is needed.
When combined with diagnostic ultrasound imaging, we can identify the damaged tissue and deliver treatment directly to the affected area.
This precision helps maximise therapeutic effect while minimising unnecessary discomfort.
3. Higher Energy Delivery
Because the energy converges at a specific point rather than dispersing from the skin surface, focused shockwave can deliver a more powerful biological stimulus to the injured tissue.
This can be particularly beneficial in long-standing chronic tendon conditions where healing has stalled.
4. Better for Calcific Tendinopathy
Focused shockwave has been extensively studied in the treatment of calcific shoulder tendinitis.
The concentrated energy can help break down calcium deposits while stimulating tissue repair and reducing pain.
5. More Versatile
Focused shockwave technology allows clinicians to tailor treatment depth and energy levels according to the tissue being treated.
This provides greater flexibility across a wide range of musculoskeletal conditions.
Does That Mean RADIAL Shockwave Doesn't Work?
Not at all.
Radial shockwave remains an excellent treatment and has helped thousands of patients recover from chronic pain.
The key difference is that focused shockwave offers a higher level of precision and allows us to treat deeper structures more effectively.
Rather than replacing radial shockwave, focused technology represents the next generation of shockwave therapy.
Why We Chose FOCUS Shockwave at Physio Edge
At Physio Edge, we continually invest in technology that enables us to provide the highest standard of evidence-based care.
Our advanced Focused Shockwave system allows us to:
Target injured tissues more precisely
Treat both superficial and deeper structures
Integrate treatment with ultrasound assessment
Offer patients a non-surgical option for chronic tendon pain
For many patients, focused shockwave can be an effective alternative to repeated injections, prolonged medication use or simply waiting and hoping symptoms improve.
Is Shockwave Therapy Right for You?
Shockwave therapy is particularly useful for chronic tendon injuries that have persisted for more than three months and have not responded to traditional treatment.
If you are struggling with a stubborn tendon problem, our physiotherapists can assess your condition and determine whether focused shockwave therapy may help.
Book an Assessment
To find out whether Focused Shockwave Therapy is suitable for your condition, contact Physio Edge and arrange an assessment with one of our experienced clinicians. We usually perform an ultrasound scan to assess the state of the tendon or soft tissue first and can guide the shockwave treatment to your needs.
Because when it comes to recovery, precision matters.
