<p>Shock Waves as a Treatment Modality for Spasticity Reduction and Recovery Improvement in Post-Stroke Adults – Current Evidence and Qualitati…
2020
Purpose: This systematic review examines intervention studies using extracorporeal shock wave therapy (ESWT) application in post-stroke muscle spasticity with particular emphasis on the comparison of two different types of radial (rESWT) and focused shock waves (fESWT). Methods: PubMed, PEDro, Scopus, and EBSCOhost databases were systematically searched. Studies published between the years 2000 and 2019 in the impact factor journals and available in the English full-text version were eligible for inclusion. All qualified articles were classified in terms of their scientific reliability and methodological quality using the PEDro criteria. The PRISMA guidelines were followed and the registrat…
Analysis of radiolucent gallstones by computed tomography for in vivo estimation of stone components.
1990
. Successful oral litholytic and other non-operative therapies of gallstones require exact determination of the stone components. Since computed tomography (CT) provides highly sensitive measurement of density, we performed a study to evaluate whether CT measurement of stone density allows a prediction of the composition of radiolucent gallstones. Twenty-eight patients presenting with 29 radiolucent gallbladder (n= 17) or common bile duct stones (n=12) were included. Prior to operative or endo-scopic therapy the attenuation values (Hounsfield Units, HU) were assessed in vivo by CT under standardized conditions (Somatom II, 125 KV, 130 mAs). After surgical or endoscopic stone removal the con…
Treatment of paediatric urolithiasis by extracorporeal shock-wave lithotripsy.
1988
Non-surgical removal of renal and ureteral stones has proven successful in adults. In this study, 21 paediatric patients have been treated with the first generation extracorporeal shock-wave lithotriptor and an additional 13 children with a second generation local shock-wave lithotriptor. A total of 47 stones was treated. Treatment-related complications such as colics (17%/18.8%) or fever (8.3%/6.2%) were minimal. Stone passage occurred in 93% and 100%, respectively of each group. Open surgery is still the treatment of choice for large staghorn calculi. Extracorporeal shock-wave lithotripsy can be performed successfully in paediatric nephrolithiasis with stones of limited size.
Revisión bibliográfica sobre la eficacia del ejercicio excéntrico como tratamiento para la tendinopatía del tendón de Aquiles
2020
Resumen Introducción: las tendinopatías son consecuencia de cargas excesivas en el tendón, por lo que son frecuentes en el ámbito laboral debido a movimientos repetitivos y posturas forzadas. La tendinopatía de Aquiles se caracteriza por una respuesta de curación desorganizada, asociada a cierto grado de neovascularización, siendo el tratamiento conservador la estrategia inicial. Objetivos realizar una revisión bibliográfica para analizr la efectividad de los tratamientos utilizados en la tendinopatía aquilea a partir de los estudios incluidos. Material y métodos: revisión bibliográfica de artículos científicos consultando las bases de datos PubMed y The Cochrane Library utilizando las pala…
Extracorporeal shock wave lithotripsy with ultrasound-guided lithostar plus.
1992
Abstract Since 1989, the Siemens lithostar plus, an upgrade of the lithostar with the ultrasonically guided overhead module, has been available for clinical use. This unit may be used for the treatment of either biliary or urinary calculi. We report on 75 patients with urinary calculi treated between March 1989 and June 1990 with the lithostar overhead module. Stone localization showed a rate of: caliceal stones 33.5%, pelvic stones 44%, upper ureteral stones 9.3% and lower ureter stones 13%. The overall disintegration rate was 86%, with a stone-free rate after 3 months of 78%.

Zewnątrzustrojowa Fala Uderzeniowa (ESW) jako alternatywna metoda wspomagająca terapię porażenia spastycznego mięśni kończyn w wyniku udaru mózgu - p…
2017
Zewnątrzustrojowa fala uderzeniowa (ESW – Extracorporeal Shock Wave) jest czynnikiem fizykalnym, którego zastosowanie kliniczne obserwowane jest w szerokiej gamie zaburzeń chorobowych, szczególnie dysfunkcji narządu ruchu. Obecnie zaobserwować można, iż lista wskazań do zabiegów ESW stale rośnie i obejmuje swym zasięgiem coraz to bardziej odmienne pod względem etiologii i patomechanizmu schorzenia ogólnoustrojowe. Niemniej jednak pamiętać należy, iż potencjalne mechanizmy biologiczne stymulacji ESW, warunkujące korzystne i pożądane efekty terapeutyczne, nie są jednoznacznie wyjaśnione. W świecie nauki w dalszym ciągu obserwowany jest brak niepodważalnych dowodów popartych zaawansowanymi bad…
Numerical treatment of radiation processes in the internal shocks of magnetized relativistic outflows
2017
Los blázares son un tipo de núcleo activo de galaxia (AGN, por sus siglas en inglés) que se encuentran entre los objetos astrofísicos más energéticos y violentos, a la par de los brotes de rayos gamma (GRB por sus siglas en inglés). Los procesos físicos y, en particular, el escenario del chorro relativista en el que se genera la radiación ultraenergética detectada por observatorios terrestres y en órbita, han conseguido atraer la atención e interés de los astrónomos y astrofísicos desde su descubrimiento. En la presente tesis investigamos el modelo de choques internos (IS) cuya hipótesis consta del choque de dos capas de plasma con geometría cilíndrica, formando dos ondas de choque que atra…
Predicted gamma-ray image of SN 1006 due to inverse Compton emission
2009
We propose a method to synthesize the inverse Compton (IC) gamma-ray image of a supernova remnant starting from the radio (or hard X-ray) map and using results of the spatially resolved X-ray spectral analysis. The method is successfully applied to SN 1006. We found that synthesized IC gamma-ray images of SN 1006 show morphology in nice agreement with that reported by the H.E.S.S. collaboration. The good correlation found between the observed very-high energy gamma-ray and X-ray/radio appearance can be considered as an evidence that the gamma-ray emission of SN 1006 observed by H.E.S.S. is leptonic in origin, though the hadronic origin may not be excluded.
