Activity: An ICF term that describes actions such as walking, climbing stairs, or getting out of bed.
AGREE II: A published, open access tool for the appraisal of clinical practice guidelines; the product of the AGREE Collaboration (http://www.agreecollaboration.org), an international collaboration of researchers and policy makers.
Alpha Level: The agreed-on value for the probability of chance in explaining the results of a study; it is typically 5% (0.05).
Analysis of Covariance (ANCOVA): A parametric statistic used to compare means and to remove the contribution of a factor that is present during treatment that was not controlled in the experimental design.
Analysis of Variance (ANOVA): A parametric statistic used to compare results for more than two groups.
Applicability: The relevance of a sample or study to your patient or patient group.
Appraise: To critically evaluate a research study.
Autocorrelation: Positive correlation among data points from the same subject.
Background Questions: Questions that supply general information and are not specific to an individual patient.
Basic Science Research: Often involves non-human research and is fundamental to evidence based physical therapy; typically tests theory.
Beta Weight: A standardized value that gives a weight (amount of contribution) to each of the independent variables in a regression equation.
Bias: Attitudes or design features that shape the results of a study.
Blinding: Restricting knowledge of the purpose of a research study, participant group, or other factors that would influence the conducting of or results from a research study (masking).
Body Functions and Structures: An ICF term that describes variables at the level of bodily functions and specific structures.
Bonferroni Correction: A planned statistical test used to correct for conducting multiple statistical tests and the possibility of a type I error.
C Statistic: A statistic to determine the probability of chance; used with small data sets or data with serial dependency.
Case Control Studies: Studies conducted after an outcome of interest has occurred. The factors that contributed to the outcome are studied in a group that has the outcome (case group) and compared to a group that does not have the outcome of interest but is similar to the case group in other factors (control group).
Case Studies: A written case description completed retrospectively and detailing the characteristics of one case and the course of intervention for that case; not a controlled single case experimental study.
Ceiling Effects: Reflect a lack of sufficient range in a measure to fully characterize a group of patients.
Celeration Line: A "best fit" line through the data beginning in the ...
