Low-intensity pulsed ultrasound (LIPUS) is a medical technology, generally using 1.5 MHz frequency pulses, with a pulse width of 200 μs, repeated at 1 kHz, at a spatial average and temporal average intensity of 30 mW/cm2.
As of 2009 research for the use of LIPUS to treat soft tissue injuries were in the early stages. As of 2012 it was being studied for dental problems.
Medical uses
A 2017 review recommended against its use to speed healing of bone fractures. Evidence as of 2014 was insufficient to justify its use to prevent non healing of bone fractures. Tentative evidence supports better healing with the us of the system in long bones that have no health after three months.
