Shock Wave Therapy is a popular, non-invasive alternative to many surgical or steroid-related procedures. With two common types of shock wave therapy available - radial and focused - what are the comparisons between the shock wave types? And how can they be used to treat different medical issues?
Shock Wave Therapy is a non-invasive procedure often used to treat injured bones, joints, muscles, tendons and other soft tissues. With no need for painkillers, shock wave therapy can offer fast pain relief and aid recovery for a range of chronic conditions including:
Repetitive strain injury (RSI)
Medial Tibial Stress Syndrome (otherwise known as shin splints)
Any other chronic soft-tissue
joint conditions causing long-term pain
Because of the conditions, it is used to treat, shock wave therapy is commonly used by athletes or those with ‘overuse’ injuries, although studies show it can benefit anyone currently undergoing physiotherapy for a range of complaints.
Shock wave therapy is a safe, effective treatment provided it is delivered in a professional setting such as Wimbledon Chiropractic & Sports Injury Clinic and can be a great way of managing pain over the long term.
Because shock wave therapy is proven to stimulate metabolic ‘healing’ reactions, it has a very high rate of success in treating difficult to treat and very painful injuries.
This is why it is often used as a safe alternative to surgery, steroids, or other treatment injections.
Radial Shock Wave Therapy consists of three parts -
- Ultrasonic pulses
- Audio acoustic pulses
- Slow shear waves.
These waves have their greatest energy at the source which weakens the farther it travels away.
Using compressed air, the projectile is accelerated to a high speed which decelerates when it’s held to the area being treated. This kinetic energy is then transmitted to the tissue and pushed outwards as a ‘radial wave’ across the affected area.
The point of ‘impact’ constitutes the highest pressure and highest energy density which eventually loses power the deeper they enter the body. For patients with more superficial, surface-level issues, radial shock wave therapy can give good results.
This tends to be for patients suffering from conditions to do with the Achilles tendon, plantar fasciitis or more specific issues such as tennis elbow.
Focused shock wave therapy - sometimes known as Focused Shockwaves - is able to provide more depth penetration for deeper tissue than radial waves, focusing its output into more localised, deeper areas.
These types of waves are generated through the use of a coil, which creates magnetic fields when a current is applied. This generates a pressure wave that can move through the medium without any loss of energy in a focused zone.
Fortunately, the site of actual wave generation experiences a minimal impact, limiting the damage to surface skin and underlying soft tissues.
While radial waves are applied all over a local area, FSWT is only applied at defined points within the body, which can be adapted depending on the depth that is required.
This makes focused therapy much better for treating any issues that affect tissues deeper within the body - including tissues close to the bone or any denser build-up that may have accrued.
In some cases, focused shock wave therapy is used in conjunction with radial therapy - typically when a patient's pain levels can't tolerate radial wave therapy or could benefit from a hybrid approach.
When comparing radial and focused shock wave therapy, the main considerations are penetration depth and localisation of the treatment. As you’d imagine, the greater the depth penetration of the waves, the easier it is to treat deep-lying issues in the tendons, muscle or bones. Similarly, depending on the size of the problem area, the type of therapy needed will typically change.
While radial waves are good at providing relief over a wider area and can treat low depth issues such as those on the Achilles or elbow, other conditions can require more focused treatments.
Radial waves are characterised by three key points
- they have lower maximum intensity,
- they have a divergent wave
- they deliver their maximum intensity to a ‘superficial’ area i.e low depth. This depth is usually around 3 - 4cm.
Focused shock waves allow for ‘adjustable’ penetration depending on where needs to be treated and are ideal for treating deeper problem areas such as hamstring, pelvic or hip issues.
Focused waves are characterised as having a higher maximum intensity, delivered as a convergent wave with an adjustable depth of focal area. This can range between 2 and 30cm.
The reason the waves are different is down to how the therapy is applied. While
- RSWT follows a pneumatic principle, using compressed air and transmitters to determine the wave shape
- FSWT follows an electroacoustic principle, using electromagnetism and coupling pads to apply deeper, focused and adjustable waves.
Radial therapy is typically more painful because of the way it is applied. The vibrating nature of the radial treatment, plus the fact it is delivered over a larger area, means it is generally only used to treat chronic conditions. Focused therapy, on the other hand, can be used in more acute cases that are causing the patient more pain, as it is typically less painful itself.
Here at Wimbledon Chiropractic & Sports Injury Clinic, we’re able to deliver both Radial and Focused shock wave therapy through the BTL shock wave systems, all delivered in our clinic in Wimbledon, London.
Which form of therapy we provide depends on your condition and tolerance. In some cases, it can be useful for a patient to have both forms of therapy to ensure their issue is fully treated.
Radial shock wave therapy will generally need more sessions than focused shock wave therapy. On average, RSWT requires around 3 - 5 sessions, while FSWT typically needs less. Obviously, this all depends on the individual's circumstances but as standard, FSWT is required less than RSWT.
