Twenty studies examining the reliability of assessment devices and outcome measures in therapeutic research were reviewed and analyzed. The 20 investigations contained 215 quantitative reliability values published in either the American Journal of Occupational Therapy or Physical Therapy during the past 5 years. The reliability studies were classified as interrater, intrarater, test-retest, or ...

Purpose A novel index, the periodontal inflamed surface area (PISA), represents the sum of the periodontal pocket depth of bleeding on probing (BOP)-positive sites. In the present study, we evaluated correlations between PISA and periodontal classifications, and examined PISA as an index integrating the discrete conventional periodontal indexes. Methods This study was a cross-sectional subgro...

PURPOSE Our purpose was to investigate cerebral blood flow disturbances in patients with bacterial and viral meningoencephalitis. METHODS Forty-two patients with acute bacterial and viral meningoencephalitis and 14 control subjects were studied using 99mTc-hexamethylpropyleneamine oxime (HMPAO) single-photon emission computed tomography (SPECT). SPECT images were evaluated semiquantitatively....

A 2-step clustering procedure, using indexes derived from principal component analysis, was used to disclose sperm subpopulations within the canine ejaculate and its relationship to sperm cryoresistance. Semen from 4 dogs was frozen-thawed by a standard protocol: before freezing, computer-assisted sperm analysis of motility and morphometry were performed; after thawing, motility analysis was pe...

kharg island as the most important oil export terminal of iran has faced entrance of various oilmaterials, so it seems necessary to know about the amount of these marine oil pollutants and their origin in this area. oil hydrocarbons has entered in this water body as a result of numerous human activities like extraction, refinement, transmission and export of raw oil or from natural and biologic...

In recent years more studies are using nonlinear dynamics to describe cardiovascular control. Because of the large dispersion of physiological data, it is important to have large studies with both male and female participants to establish a range of physiological healthy values. This study investigated the effect of gender and age on nonlinear indexes. Nonlinear scaling properties were studied ...

water content plays an important role in the process of plant photosynthesis and biomass accumulation. many methods have been developed to retrieve canopy leaf water content from remote sensing data. however, the validity of these methods has not been verified, which limits their applications. this study estimates the leaf water content (lwc) of winter wheat with three most widely used indexes:...

M mode echocardiographic anteroposterior indexes of left ventricular function derived from long and short axis parasternal planes were compared in one hundred cases. In all the disease groups studied the paired values were within acceptable statistical limits of comparability and interchangeability; that is they were within two standard deviations of the mean difference in both directions. Valu...
