For physical therapists observational gait assessment is preferable to instrumented gait assessment in the clinical setting. Existing observational gait assessment tools used in clinical practice were reviewed in terms of their validity, repeatability, sensitivity, and specificity. Most gait assessment tools lacked information concerning their validity or repeatability. In addition, most gait assessment tools had not had their sensitivity and specificity adequately evaluated. Current approaches to the development and use of observational gait assessment tools have been characterised by a top down approach, designing what is useful without any understanding of the appropriateness of a tool's content, construction, and so forth. We would advocate a more structured approach, by assessing gait using the gold standard of instrumented gait analysis and designing an observational gait assessment tool based on the data.

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
