BACKGROUND Conflicting reports in the literature have raised the question whether radial extracorporeal shock wave therapy (rESWT) devices and vibrating massage devices have similar energy signatures and, hence, cause similar bioeffects in treated tissues. METHODS AND FINDINGS We used laser fiber optic probe hydrophone (FOPH) measurements, high-speed imaging and x-ray film analysis to compare...

The time harmonic Green function for a point load in an unbounded fluid-saturated porous solid is derived in the context of Biot's theory. The solution contains the two compressional waves and one transverse wave that are predicted by the theory and have been observed in experiments. At low frequency, the slow compressional wave is diffusive and only the fast compressional nd transverse waves r...

Few studies report the possible correlation pain-paratendon microvascularity during the painful phase of the chronic Achilles tendinopathy and the efficacy of the radial shock wave therapy respect to other therapies. The aim of the present longitudinal, controlled study is to demonstrate the variation of the tendon micro vascularization in athletes affected by Achilles tendinopathy and the effi...

BACKGROUND Recent literature shows evidence for effective treatment for plantar fasciitis using either focused or radial shock waves. Up to now no research has been available which compares these different procedures. We hypothesized (H(0) Hypothesis) that for plantar fasciitis, outcomes following focused or radial shock wave treatment were equal. MATERIALS AND METHODS For this pilot study, 3...

The revival structure and evolution of Rydberg wave packets are studied on a time scale much greater than the revival time trev. We find a new level of revival structure and periodic motion different from that of the known fractional revivals. The new sequence of revivals culminates with the formation of a wave packet that more closely resembles the initial packet than does the full revival at ...

In this paper, Exp-function and (G′/G)expansion methods are presented to derive traveling wave solutions for a class of nonlinear space-time fractional differential equations. As a results, some new exact traveling wave solutions are obtained.

OBJECTIVE To establish through analysis of the radial pressure pulse waveform the dose dependent effects of glyceryl trinitrate (GTN) on properties of different blood vessels. DESIGN Radial pulse waveform was measured in randomised order before, during a five hour application of a GTN patch delivering 0.104-0.625 mg/h, and for two hours after patch removal. The radial pressure waveform (Milla...

Two-dimensional measurements of density fluctuations are obtained in the radial and poloidal plane of the DIII-D tokamak with the Beam Emission Spectroscopy ~BES! diagnostic system. The goals are to visualize the spatial structure and time evolution of turbulent eddies, as well as to obtain the 2D statistical properties of turbulence. The measurements are obtained with an array of localized BES...
