BACKGROUND AND PURPOSE The purpose of this study was to assess the reliability, construct validity, and sensitivity to change of the Lower Extremity Functional Scale (LEFS). SUBJECTS AND METHODS The LEFS was administered to 107 patients with lower-extremity musculoskeletal dysfunction referred to 12 outpatient physical therapy clinics. METHODS The LEFS(More)
BACKGROUND AND PURPOSE The Chedoke-McMaster Stroke Assessment measures the physical impairments and disabilities that impact on the lives of individuals with stroke. This measure has three overall purposes: 1) to stage motor recovery to classify individuals in terms of clinical characteristics, 2) to predict rehabilitation outcomes, and 3) to measure(More)
OBJECTIVE To examine the relation between responsiveness coefficients derived directly from a calculation of average change resulting from a treatment intervention (Responsiveness-Treatment or RT) and those derived from retrospective analysis of changed and unchanged groups (Responsiveness Retrospective or RR) based on a global measure of change. METHOD(More)
Self-report measures of disability are being used more frequently to assess patients' outcomes in clinical practice. This study examines the reliability, validity, and sensitivity to change of the Patient-Specific Functional Scale when applied to persons with neck dysfunction. The Patient-Specific Functional Scale and Neck Disability Index were applied at(More)
BACKGROUND AND PURPOSE The purpose of this study was to establish the interrater reliability of assessments made with the Fugl-Meyer evaluation of physical performance in a rehabilitation setting. SUBJECTS Twelve patients (7 male, 5 female), aged 49 to 86 years (mean = 66), who had sustained a cerebrovascular accident participated in the study. All(More)
BACKGROUND AND PURPOSE The Roland-Morris Questionnaire (RMQ) is a self-administered disability measure in which greater levels of disability are reflected by higher numbers on a 24-point scale. The RMQ has been shown to yield reliable measurements, which are valid for inferring the level of disability, and to be sensitive to change over time for groups of(More)
BACKGROUND Choosing an adequate measurement instrument depends on the proposed use of the instrument, the concept to be measured, the measurement properties (e.g. internal consistency, reproducibility, content and construct validity, responsiveness, and interpretability), the requirements, the burden for subjects, and costs of the available instruments. As(More)
BACKGROUND The extent to which SF-12 scores reflect SF-36 scores has not been well studied. OBJECTIVES One purpose was to compare the sensitivity to change of the SF-36 Physical Function sub-score, and the Physical Component Summary Scores (PCS) of the SF-36 and SF-12 on patients with low back pain (LBP). A second purpose was to determine if the SF-12(More)
STUDY DESIGN This investigation had two components: one was an item analysis that examined data obtained at the initial patient assessment, and the second was a validation study that used a pretest-posttest design. OBJECTIVES The authors' goal, in this study, was to determine whether a shorter version of the Roland-Morris Questionnaire could be developed(More)
