"Comparação da escala CR10 de Borg com a escala analógica visual (VAS) na avaliação da dor em pacientes com disfunções temporomandibulares". / Comparison of CR10 Borg’s Scale with Visual Analogue Scale (VAS) to assess pain in patients with Temporomandibular Disorders

Bacci, Adriana do Vale Ferreira 23 April 2004 (has links)
A Visual Analogue Scale (VAS) e a escala Category-Ratio (CR10) foram aplicadas para mensurar a dor em pacientes com Disfunções Temporomandibulares (DTMs) em dois estudos. No primeiro estudo, em 35 pacientes (Grupo I) foram aplicadas uma versão modificada da escala CR10 em português e a VAS para mensurar a dor espontânea, durante função orofacial e durante palpação antes e após tratamento odontológico. A modificação na CR10 consistiu em um desmembramento das categorias verbais e da escala numérica apresentadas cada uma delas em única coluna em mesma folha. Os coeficientes de correlação de Pearson entre as pontuações da VAS e da CR10 foram 0,85 antes do tratamento odontológico e 0,9 após o tratamento, indicando alta validade de critério. A associação entre os valores numéricos e as categorias verbais da Escala CR10 Modificada mostrou diferenças em relação ao que é proposto na escala original. As categorias: “Moderado", “Forte" e “Muito Forte" foram associadas a valores superiores aos originais. O segundo estudo foi planejado para investigar se essas discrepâncias nas associações das categorias com os seus valores numéricos eram replicáveis e verificar se não dependiam da forma de apresentação da escala CR10 modificada. Para isso, as escalas foram aplicadas para medir dor em duas novas amostras de pacientes com DTMs antes do tratamento odontológico. A CR10 com nova modificação e a VAS foram aplicadas à primeira amostra (Grupo II , n=23 pacientes). A modificação na CR10 consistiu na apresentação primeiro da escala numérica em uma coluna seguida pela apresentação das categorias verbais em três colunas. A CR10 original e a VAS foram aplicadas à segunda amostra (Grupo III, n=17 pacientes). Os coeficientes de correlação de Pearson foram 0,9 para o Grupo II e 0,8 para o Grupo III, indicando também alta validade de critério. Assim como no primeiro estudo, na escala CR10, as categorias verbais: “Moderado", “Forte" e “Muito Forte" foram associadas na escala numérica a valores superiores aos propostos na escala original Em ambos estudos, a escala CR10 foi a mais bem avaliada pelos pacientes, segundo a facilidade de compreensão das instruções e a adequação para o registro da dor. Evidencia-se a necessidade de mais estudos para validar a escala CR10 para a língua portuguesa para determinar com precisão a associação das categorias verbais aos valores numéricos. / Visual Analogue Scale (VAS) and Category-Ratio Scale (CR10) were applied to measure pain in patients with Temporomandibular Disorders (TMDs). In the first study, a modified version of CR10 translated to Portuguese and VAS were applied to measure spontaneous pain, functional pain and pain by touch after and before dentistry treatment in 35 patients (Group I). The CR10 modification consisted of presenting the verbal categories and the numerical scale in separated columns in a sheet. Coefficients of Pearson’s correlation between VAS and CR10 scores were .85 and .90 respectively before and after treatment, indicating a high criterion validation. The association of numerical values and verbal categories of Modified CR10 scale were different from the original CR10. The verbal expressions “moderate", “strong" and “very strong" were attached to higher values. In the second study we investigated if these discrepancies in attaching the verbal categories to the numerical scale were replicable and if they were not an artifact of the way of presenting the modified CR10 scale. To check these topics, the scales were applied to measure pain in two new samples of patients with TMD before dentistry treatment. A new modified version of the CR10 scale and the VAS were applied to the first sample (Group II, n=23 patients). This modification in CR10 scale consisted of presenting first the numerical scale in separate column, and then the verbal categories distributed in three columns. The original CR10 and VAS were applied to the second sample (Group III, n=17 patients). Coefficients of Pearsons correlation between CR10 and VAS were .9 for Group II and .8 for Group III, indicating also high criterion validation. As indicated in the first study, some verbal categories were attached to the numerical scale at higher values than those ones in the original scale. In both studies,, most patients judged the CR10 easier to be understood and more adequate to measure pain than VAS. There is evidence of the necessity of more studies to validate CR10 to Portuguese to determine with precision the association of the verbal categories to the numeric values.

Resistance breathing with PEP and CPAP : effects on respiratory parameters

Sehlin, Maria January 2014 (has links)
Background: Positive expiratory pressure (PEP) and continuous positive airway pressure (CPAP) are two forms of resistance breathing used in spontaneously breathing patients. With a threshold resistor or a flow resistor, both PEP and CPAP provide a positive (elevated) pressure level during the expiratory phase. With PEP, inspiratory pressure is negative, i.e. lower than ambient air pressure, as during a normal inspiration, but with CPAP, the inspiratory pressure is positive, i.e. higher than ambient air pressure. Methods: This thesis is based on four separate studies in which four different breathing devices, a PEP-bottle (threshold resistor device), a PEP-mask (flow resistor device), a threshold resistor CPAP and a flow resistor device were investigated. Paper I, II and III are based on studies in healthy volunteers. Paper IV is a bench study performed in a hypobaric chamber. Paper I examined differences between two PEP devices, the PEP-bottle and the PEP-mask. Paper II evaluated the performance of a flow resistor CPAP device, (Boussignac CPAP). Paper III investigated the effect of two PEP-devices, a PEP-bottle and a PEP-mask and two CPAP devices, a threshold resistor CPAP and a flow resistor CPAP, on inspiratory capacity (IC). In paper IV, the effect of changes in ambient pressure on preset CPAP levels in two different CPAP devices was compared. Results: With the PEP bottle, both expiration and inspiration began with a zero-flow period during which airway pressure changed rapidly. With the PEP-mask, the zero-flow period was very short and the change in airway pressure almost non-existent (paper I). During normal breathing with the Boussignac CPAP, changes in airway pressure were never large enough to reduce airway pressure below zero. During forced breathing, as airflow increased, both the drop in inspiratory airway pressure and the increase in expiratory airway pressure were potentiated (paper II). IC decreased significantly with three of the breathing devices, the PEP-mask and the two CPAP devices (paper III). With the threshold resistor CPAP, measured pressure levels were close to the preset CPAP level. With the flow resistor CPAP, as the altitude increased CPAP produced pressure levels increased (paper IV). Conclusion: The effect on airway pressure, airflow, IC and the effect of changes in ambient air pressure differ between different kinds of resistance breathing devices. These differences in device performance should be taken into consideration when choosing the optimal resistance breathing device for each patient.
