In the crowded field of modern electrotherapy modalities, focused shockwave has emerged as one of the most powerful and effective treatment tools on the market today.
Priced higher than radial shockwave therapy units, focused shockwave is typically used by specialists in orthopedics, trauma and sports medicine.
What’s the difference between radial and focused shock waves?
While radial waves are effective at providing relief over a wider area and can treat shallow 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 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.
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.
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.
In summary, focused shock waves provide greater depth penetration than radial waves, focusing output deeper into more localised areas.
How are Shockwaves produced?
Focused Shockwaves 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.
Areas of use:
Focused shockwave is used effectively on chronic conditions such as painful soft tissue diseases, tendinoses and other orthopedic conditions.
• Bone healing deficiencies in the extremitybones, such as delayed fracture healing andnonunion (pseudarthrosis)• Patellar tip syndrome (jumper’s knee)• Calcified shoulder (tendinosis calcarea)• Fasciitis plantaris with and without heel spur• Achillodynia• Tennis elbow (epicondylitis radialis)• Golfer elbow (epicondylitis ulnaris)• Avascular Necrosis• Osteoarthritis• Adjunctive use
How effective is Focused Shockwave?
Multiple studies have been performed on the efficacy of treatment of these devices.
By way of example Patellar Tip Syndrome. At point of 2-3 year follow-up, 90% of patients reported excellent to good results in a randomized controlled study. Plantar Fasciitis, a prospective, randomized, controlled, blinded study reported 77% of patients had excellent to good outcomes
