BACKGROUND The aim of this study is to compare the effects of laser therapy and shock wave therapy for symptoms treatment among patients with MPS in the upper trapezius muscle. MATERIALS AND METHODS In a clinical trial study, 46 patients were selected based on the clinical criteria and physiathrist diagnosis. Subjects were randomized into two groups as follows: Twenty individuals were assigne...

[Purpose] This study aimed to analyze the effect of extracorporeal shock wave therapy on the shoulder function of patients with calcific tendinitis through a 12-week follow-up. [Subjects and Methods] A total of 34 patients with calcific tendinitis participated in this study. In the extracorporeal shock wave therapy group, 18 patients received 6-week extracorporeal shock wave therapy and 12-week...

a fundamental topic in computational fluid dynamics is the role of coordinate particularly for searching optimized coordinates. the objective of this study is the numerical modeling of supersonic flows using a new coordinate system i.e. unified coordinate system (ucs) uses moving mesh with motionless viewing window technique. ucs has an advantage over traditional coordinate systems (eulerian an...

In blast-related mild traumatic brain injury (br-mTBI) little is known about the connections between initial trauma and expression of individual clinical symptoms. Partly due to limitations of current in vitro and in vivo models of br-mTBI, reliable prediction of individual short- and long-term symptoms based on known blast input has not yet been possible. Here we demonstrate a dose-dependent e...

An approximate, semi-analytical method to compute the net effect of the passage of a planar shock through a steady compressible vortex is developed. To compute the approximate post-shock fields, the steady pre-shock vortex is decomposed into a sum of frozen sinusoidal modes, the shock wave is treated as an instantaneous event (an ansatz most suited to weak shocks), and the interaction of each f...

BACKGROUND Osteosarcoma is the most prevalent primary malignant bone tumor, but treatment is difficult and prognosis remains poor. Recently, large-dose chemotherapy has been shown to improve outcome but this approach can cause many side effects. Minimizing the dose of chemotherapeutic drugs and optimizing their curative effects is a current goal in the management of osteosarcoma patients. MET...

PURPOSE Because the shock wave passes through various body tissues before reaching the stone, stone composition may affect the treatment efficacy of shock wave lithotripsy (SWL). We investigated the effect of various tissue components along the shock wave path on the success of SWL. MATERIALS AND METHODS From October 2008 to August 2010, a total of 206 patients with kidney stones sized 5 to 2...

One possible effect due to impact cratering is the transformation of part oT the kinetic energy of the projectile to energy in the electromagnetic field. Shock-induced polarization of piezoand dielectric material could be the mechanism by which this is accomplished. Although the estimates show that the fraction of kinetic energy transformed by this mechanism is rather small, the effect could be...
