BACKGROUND The purpose of this study is to examine current beliefs about the use, the clinical importance, the theoretical fundamentals and the utilization criteria of therapeutic ultrasound (TUS) among physical therapists on the clinical practice in orthopedic and sports physiotherapy in Brazil. METHODS A brief survey was developed based on previous studies and was sent to 55 physical therap...

The use of therapeutic ultrasound as an element of physiotherapy practice is well established, but the nature of that practice has changed significantly over the last 20 years. This paper aims to review the rationale and range of applications for which this modality is employed in current practice. Whereas in the past, its primary use was as a thermal modality, it is argued that currently, it i...

OBJECTIVE The purpose of this study was to evaluate the potential benefit of an ultrasonic device in apical surgery on the outcome of treatment. STUDY DESIGN A randomized prospective design was used in a standardized treatment protocol. Patients were allocated to treatment with an ultrasonic device (P-Max Newtron) or treatment with a bur in an otherwise similar protocol. One year after treatm...

Light focusing plays a central role in biomedical imaging, manipulation, and therapy. In scattering media, direct light focusing becomes infeasible beyond one transport mean free path. All previous methods1-3 to overcome this diffusion limit lack a practical internal "guide star."4 Here we proposed and experimentally validated a novel concept, called Time-Reversed Ultrasonically Encoded (TRUE) ...

[Purpose] We investigated the effect of low-intensity pulsed ultrasound and cryotherapy on joint function recovery and C-reactive protein (CRP) levels of patients with total knee replacement. [Subjects] Forty-six patients with total knee replacement were recruited and allocated to either low-intensity pulsed ultrasound therapy (n=15), cryotherapy (n=15), or a combination of both (n=16). Therapy...

BACKGROUND Dosimetry for Ultrasound Therapy (DUTy) is a large international project which addresses the development of a metrological infrastructure for the determination of ultrasound exposure and dose to tissue. METHODS In order to seek the views of the wider therapy ultrasound community and to review dose and in situ exposure quantities that have been suggested or used previously, a web-ba...

Background: Magnetic resonance guided high intensity focused ultrasound (MRgHIFU) therapy is a promising new technology to ablate tissues non-invasively. Exact knowledge of the location of the target organ as well as the risk structures on the beam path is crucial to a successful therapy. One particularly important structure is the ribcage due to its vicinity to the liver, and bones’ absorption...

Ultrasonic speech is a novel technology which implies exciting human vocal tract (VT) with an ultrasonic signal to provide a speech mode in the ultrasonic frequency range. This has several applications including speech-aid prostheses for voice-loss patients, silent speech interfaces, secure mode of communication in mobile phones and speech therapy. Linear prediction has recently been proven to ...
