The use of ultrasound in the treatment of soft-tissue injuries is
well established in the practice of Physical Therapy.
Traditional MegaHertz frequencies have limitations in terms of the depth
of penetration and energy input levels. Whereas the exact scientific
definition of the ‘what and how’ in regard to the effect ultrasound
has upon tissues is still under discussion, it is clear that maintaining
the displacement wave and minimizing attenuation is key to treating the
tissues thoroughly. Vibrations in the megahertz range are attenuated
rapidly and are reflected at the endosteal surface making them
efficacious only in relatively superficial tissue layers.
In 1993 the first genuinely low frequency, ‘longwave length’ ultrasound machines were developed and brought to market. Kilohertz vibrations, having a much longer wavelength, have the advantage of far superior depth of penetration, even through bone, with little attenuation. This allows for greatly reduced input energy levels making the modality significantly safer.
The Duoson is the only machine to have both Longwave ultrasound and a 1 Megahertz output in the same treatment head. This allows for use of the modalities separately and together.
