A Comparison of Kinesio® Taping Methods for Subjects with Patellar Tendonitis

Gallais, Kathleen Yvette January 2020 (has links)
This project investigated the effects of Kinesio® Tape on pain, kinesiophobia, and proprioception in participants with patellar tendonitis. Thirty participants with patellar tendonitis were divided into three groups, the first received a supportive Kinesio® Tape application at the knee, the second received a facilitative application at the hip, and the third received both. A Visual Analog Score, Tampa Scale for Kinesiophobia score, and a proprioceptive score quantified through the Biodex Balance System were obtained both immediately after application, and 24 to 36 hours following. Statistically significant improvement in VAS scores and in proprioceptive ability with eyes closed 24 to 36 hours following Kinesio® Tape application was observed under all interventions. Kinesio® Tape application for pain, cause of pain and proprioception may assist patients with patellar tendonitis.

Effekten av tejpning vid patellofemoralt smärtsyndrom : En systematisk litteraturstudie / The effects of taping in patients with patellofemoral pain syndrome : A Systematic Review

Jonasson, Linn, Wennberg, Sara January 2022 (has links)
Abstrakt Bakgrund: Patellofemoralt smärtsyndrom är ett vanligt förekommande smärttillstånd. Tejpning som behandlingsalternativ är väl använt av fysioterapeuter, trots bristande vetenskapligt underlag. Det skulle vara av värde att undersöka vad tidigare evidens säger kring tejpning som behandling vid PFSS.  Syfte: Att sammanställa och kartlägga om tejpning som isolerad eller kombinerad behandling minskar smärta hos personer med PFSS. Kvalitetsgranska resultaten av randomiserade kontrollstudier (RCT) med PEDro och bedöma dess tillförlitlighet med GRADEstud.  Metod: För systemisk litteratursökning formulerades följande PICO. P: Friska personer med PFSS, I: Tejpning, C: Annan behandling/ingen behandling, O: Smärtintensitet mätt med etablerade mätinstrument. Inklusionskriterier var randomiserade kontrollerade studier, studier publicerade de senaste 20 åren, studier på engelska och studier som finns att tillgå i fulltext.Exklusionskriterier var studier som är tillgängliga mot avgift. Systematisk sökning genomfördes i Pubmed, Cochrane och Web of Science. Åtta studier inkluderades och granskades med PEDro. GRADEstud användes för att bedöma resultatets tillförlitlighet.  Resultat: De åtta inkluderade studiernas kvalitet varierade mellan medelgod och hög kvalitet, enligt PEDro scale. Gällande kombinerad behandling fann två av de sex inkluderande studierna en signifkant skillnad. Gällande isolerad behandling fann en av de två studierna en signifikant skillnad. Det sammanvägda resultatets tillförlitlighet graderades som mycket låg (+), enligt GRADEstud.  Slutsats: Tejpning som behandling har en tvetydig evidens. Därmed kan denna studie inte avgöra huruvida tejpning har smärtlindrande effekt eller ej vid PFSS. / Abstract Background: Patellofemoral pain syndrome (PFPS) is a common pain condition. Taping as a treatment option is well used among physiotherapists, despite lack of evidence. It would be of value to investigate what earlier evidence says about taping as a treatment option in PFPS.  Objective: Compile and survey whether taping as an isolated or combined treatment has an effect on pain for people with PFPS. Quality review the results of randomized control studies (RCTs) with PEDro and assess its reliability with GRADEstud. Method: Structured question according to PICO. P: Healthy people with PFPS, I: Taping, C: Other / no treatment, O: Pain intensity measured with established measuring instruments. Inclusion criterias were RCTs, studies published in the last 20 years, studies in English and studies in full text. Exclusion criteria were studies available for a fee. Searches were conducted in Pubmed, Cochrane and Web of Science. Eight studies were included and reviewed with PEDro and GRADEstud.  Results: The eight included studies quality varied between moderate to high, according to the PEDro scale. Regarding combined treatment, two of the six included studies found a significant difference. Regarding isolated treatment only one of the two studies found a significant difference. The reliability of the weighted result was rated as very low (+), according to GRADEstud.  Conclusion: Taping as a treatment option has ambiguous evidence. Therefore, this study can not determine whether taping has a pain-relieving effect or not in PFPS.

Bureaucratizing Participation: Stakeholders' Perceptions of the Administrative Rules Governing Public Participation in the Hampton Roads Transportation Planning Organization

Kadir, Nadhrah A. 28 September 2015 (has links)
This dissertation explores multiple stakeholders' perceptions with regard to administrative rules governing public participation in the Hampton Roads Transportation Planning Organization (HRTPO) in Virginia. In 2007, the HRTPO received conditional certification during its quadrennial review with seven corrective actions related to public participation. Subsequently, it started to reform its public participation practices, and in 2012 it received full certification. This study explores how the HRTPO stakeholders perceive the administrative rules that govern public participation processes, more positively (as 'green tape') or more negatively (as 'red tape'), and how those perceptions have changed since 2007, relying on in-depth interviews as well as archival documents. Before 2007, top management officials had pessimistic perceptions of public participation in general and the rules in particular. The negative perceptions changed when new senior staff arrived in 2008 and initiated reforms, most notably by hiring a public involvement administrator. Acting as a transformative leader, this administrator began to adopt outreach programs, which stakeholders considered successful. By unpacking the notion of stakeholder red tape, guided by the attributes of stakeholder red tape and green tape, this study found that stakeholders perceived the rules more positively than they did in 2007. / Ph.

HIGH RATE DIGITAL CASSETTE RECORDERS

Banks, Simon 11 1900 (has links)
International Telemetering Conference Proceedings / November 04-07, 1991 / Riviera Hotel and Convention Center, Las Vegas, Nevada / Recorders conforming to IRIG Standards have served the data recording community well for many years. Initially, most systems were analog in nature, recording data in either direct or FM modes but as the need for digital recording developed, the IRIG recorder was successfully adapted for this purpose by the addition of formatting and coding sub-systems to form the High Density Digital Recorder (HDDR). Today, user requirements for higher speed, higher capacity and more convenient systems have presented equipment designers with new challenges in terms of the correct choice of technology and system architecture. It is not surprising that system designers should turn for inspiration first to the very high speed transverse and helical products which had been developed for the broadcast industry since these technologies possess many of the attributes necessary for a high rate digital data recorder. It is unfortunate that it has now become a truism that the only logical progression from the longitudinal IRIG system is by means of rotary technology. Recent developments in a technology known as micro-track recording now call this assumption into question. Recording systems based on micro-track technology are available and others are in an advanced state of development, and these offer a costeffective, attractive and low risk alternative to rotary systems for both high rate data capture and tape mass storage applications.

INCREASING DATA DENSITY ON 1/2 INCH CASSETTE TAPE

Buschbach, Charles W. 11 1900 (has links)
International Telemetering Conference Proceedings / October 30-November 02, 1995 / Riviera Hotel, Las Vegas, Nevada / Half inch Super VHS (S-VHS) tape is an exceptional media for recording telemetry instrumentation data. Due to high volume mass production for the commercial and industrial video markets, high quality S-VHS media is available at a low cost. Advances in head technology as well as data path electronics contribute to increased data densities recorded on this media. Present system capabilities of 50,000 bits per inch will soon be replaced with newer technology systems that will record at linear densities up to 100,000 bits per inch.

Desenvolvimento de um gerador de microplasma utilizando a tecnologia LTCC. / Development of a microplasma generator using the LTCC technology.

Yamamoto, Roberto Katsuhiro 16 May 2008 (has links)
Microplasmas são plasmas gerados em espaços com dimensões reduzidas, tipicamente, de dezenas a centenas de micrômetros. Apresentam como principal vantagem a possibilidade de se obter plasmas frios com densidades elevadas com baixo consumo de energia em pressões maiores do que em reatores convencionais, reduzindo sensivelmente o custo do equipamento. Um gerador de microplasma inédito foi desenvolvido neste trabalho, utilizando a tecnologia LTCC. O dispositivo é constituído por dois eletrodos paralelos de prata-paládio perfurados por centenas de microfuros, formando microcanais. O microplasma é gerado na região entre os eletrodos e é conduzido para fora do gerador através dos microcanais, constituindo um plasma remoto que pode interagir com a superfície de um material a ser processado. Os microfuros formam a estrutura de um microcatodo oco. Na fabricação, as camadas de cerâmica verde foram usinadas com uma máquina de CNC e os eletrodos foram obtidos por serigrafia. O método de pós-sinterização utilizando a cerâmica de transferência mostrou ser bastante reprodutível e produziu eletrodos totalmente planos, sem arqueamento. O gerador de microplasma foi instalado dentro de um reator RIE convencional e o microplasma foi gerado em DC e RF. A caracterização dos microplasmas de Ar, O2, N2 e He foi realizada por meio de curvas VxI, sonda dupla de Langmuir e espectroscopia de emissão óptica. Para descargas DC, em condições de baixa vazão de gás e elevada pressão, as curvas VxI mostraram três modos de descarga: catodo oco, normal e anormal. O efeito catodo oco foi evidenciado também pelos espectros de emissão óptica que mostraram raias na faixa de 300 a 450 nm, que indicam a presença de elétrons de alta energia. Essas raias foram mais fortemente evidenciadas em descargas RF. Temperaturas de elétrons elevadas, na faixa de 10 a 30 eV, foram obtidas através de medidas com a sonda dupla de Langmuir, nas condições em que o efeito catodo oco foi observado. A aplicabilidade do gerador de microplasma foi testada com foco no tratamento de superfície de polietileno e os resultados mostraram alta capacidade de redução do ângulo de contato e aumento da molhabilidade superficial, demonstrando, conseqüentemente, substancial modificação da energia de superfície do material, através desse processo a microplasma. / Microplasmas are plasmas generated in spaces with reduced dimensions, typically ranging from tens to hundreds of microns. The major advantage of a microplasma generator is the possibility of glow discharge generation with high plasma density and low power consumption at pressures higher than usually observed in conventional plasma reactors, reducing considerably the equipment cost. A novel structure of microplasma generator was developed in this work, using the LTCC technology. The device is composed of two silver-palladium parallel electrodes perforated by hundreds of microholes, constituting microchannels. The microplasma itself is formed between the electrodes and the plasma species are carried through the microchannels to reach the processing chamber, where they can interact with the samples to be treated. The presence of microholes can promote microhollow cathode effect. In the fabrication process, green tapes were micromachined by using a CNC and the electrodes were obtained by screen printing. The post-fire method using transfer tapes has demonstrated to be very reproducible and produced very flat electrodes. The microplasma generator was mounted into a conventional homemade reactive ion etching (RIE) reactor and driven by DC and RF power supply. Characterization of Ar, O2, N2 and He microplasmas was performed by means of VxI characteristics, double Langmuir probe and optical emission spectroscopy. For DC discharges, the VxI characteristics revealed three distinct regions: microhollow cathode mode, normal glow and abnormal glow, for low gas flow rate and high pressure conditions. The microhollow cathode effect was evidenced by optical emission that presented lines in wavelengths between 300 and 450 nm, indicating the presence of high energy electrons. These emission lines have shown to be more intense in RF discharges. Double Langmuir probe diagnostic showed high electron temperatures ranging from 10 and 30 eV, under the microhollow cathode effect conditions. The microplasma generator applicability was tested focusing on the surface treatment of polyethylene film. The results showed high efficiency of this process in reducing water contact angle and thus substantially increasing the polyethylene wettability, thus demonstrating effective modification of surface energy of the material. One can conclude that among other potential applications for material processing, the microplasma generator has already shown to be a reliable tool to modify the surface energy of materials.

Robust repair methods of primary structures in composite

Ramström, Marcus, Gungner, Mattias January 2013 (has links)
A request of material change when performing repairs on composite parts of SAABs JAS 39 Gripen has lead to the initiation of this project. The aim is to create a quicker and more robust repair method. The requested method of repair is to use a direct-cured repair patch made of CFRP fabric instead of CFRP tape and to mount the patch with a scarf joint, see Figure 1.1. The fabric patch should then provide a robust quasi-isotropic repair, where the operator not is dependent of complete design data such as ply-directions etc. Today tape repairs are made on tape laminate and fabric repairs made on fabric laminate. The new method is to repair tape laminate with a fabric patch. This project will evaluate the possibility of implementing this method. The work started with a literature study to find out how repairs in composite parts of the airframe are being performed today. SAABs in-house analytical tools were then used to try to predict the results and examine some of the details in the questions at issue. Finite element models were then constructed to simulate a previous physical test program conducted to validate a repair method using a step joint and a direct-cured repair patch. If the FE models could show similar results as the physical tests the results from the FE models then can be assumed to be credible. The results of this project indicate that the change from fabric to tape in the repair patch can be done without disturbing the load path of a quasi isotropic composite laminate. Fabric repairs in orthotropic composite plates results in a knock-down of about 40%. The use of a scarf joint instead of a step joint should also work well as the repair patches show similar strains in the centre of the patches. The difference between step joint and scarf joint is the strain near the edge of the patch. It increases with scarf joint and it may lead to an earlier fibre failure in the repair patch. Results from the analysis of the bonded joint indicate that a scarf joint yields in a lower and more evenly distributed shear stress than the step joint. This indicates that the bonded joint in the step joint will reach failure earlier then the scarf joint.
