Pressure, frequency, energy, applicator size and service intervals all matter in context, and figures from different machine types are not always directly comparable.
Pressure (Bar)
Common on pneumatic radial systems. It describes system pressure, not a universal measure of tissue energy across all device designs.
Frequency (Hz)
Usually expresses pulses per second. Higher frequency can change treatment pace but is not automatically “more effective.”
Energy flux density
Commonly used for focused shock waves and reported in mJ/mm². It is more clinically interpretable for focused systems than comparing Bar values across unrelated devices.
Applicator / transmitter size
Head geometry changes contact area and energy distribution. Manufacturer-specific heads should be used according to instructions rather than assumed to map directly to treatment depth.
Pulse life and duty cycle
These affect ownership cost. Ask which components are wear items and what happens when the rated interval is reached.
