Focused Shockwave Therapy (ESWT) Brisbane

Focused shockwave and radial pressure wave are not the same thing, even though both are often called "shockwave" and are sometimes grouped together. The difference is physical. A focused system (piezoelectric, electromagnetic or electrohydraulic) generates a true acoustic shock wave that converges at a focal point set at a defined depth within the tissue — so energy is concentrated where the target is. A radial (ballistic) pressure wave device generates a pressure wave with its maximum intensity at the applicator surface, spreading out and weakening with depth — which is why the international shockwave society notes it is more accurate to call it a pressure wave than a shock wave. In practice, focused devices suit deeper or more precisely localised targets; radial devices are more superficial and broad-field.

How the energy is thought to help. The leading theory for both is mechanotransduction — the acoustic energy is sensed by cells and converts into biological signals, rather than simply "breaking things up." Proposed effects that recur across the literature include release of nitric oxide and growth factors, new blood-vessel formation (angiogenesis), improved local blood flow, reduced sensitisation of pain nerves, and stimulation of tissue remodelling. In laboratory and animal studies there is also evidence for improved peripheral nerve regeneration and remyelination, which is part of the rationale for using shockwave in some nerve-related conditions. These mechanisms are well described in principle; the exact device, dose and protocol that work best for a given condition are still being refined.

We use a focused shockwave system, which allows the energy to be directed to deeper target tissues such as tendon attachments.
