Global memory models are evaluated by using data from recognition memory experiments. For recognition, each of the models gives a value of familiarity as the output from matching a test item against memory. The experiments provide ROC (receiver operating characteristic) curves that give information about the standard deviations of familiarity values for old(More)
We analyze how subjects make causal judgements based on contingency information in two paradigms. In the discrete paradigm, subjects are given specific information about the frequency a, with which a purported cause occurs with the effect; the frequency b, with which it occurs without the effect; the frequency c, with which the effect occurs when the cause(More)
BACKGROUND The interpretation of the change scores of the Barthel Index (BI) in follow-up or outcome studies has been hampered by the fact that its minimal clinically important difference (MCID) has not been determined. OBJECTIVE This article was written to establish the MCID of the BI in stroke patients. METHODS Both anchor-based and distribution-based(More)
BACKGROUND Functional limitation of the upper extremities is common in patients with stroke. An upper-extremity measure with sound psychometric properties is indispensable for clinical and research use. OBJECTIVE The purpose of this study was to compare the psychometric properties of 4 clinical measures for assessing upper-extremity motor function in(More)
OBJECTIVE To provide empirical justification for selecting motor scales for stroke patients, the authors compared the psychometric properties (validity, responsiveness, test-retest reliability, and smallest real difference [SRD]) of the Fugl-Meyer Motor Scale (FM), the simplified FM (S-FM), the Stroke Rehabilitation Assessment of Movement instrument(More)
BACKGROUND AND PURPOSE To improve the utility of the Berg Balance Scale (BBS), the aim of this study was to develop a short form of the BBS (SFBBS) that was psychometrically similar (including test reliability, validity, and responsiveness) to the original BBS for people with stroke. SUBJECTS AND METHODS A total of 226 subjects with stroke participated in(More)
BACKGROUND AND PURPOSE This study compared the psychometric properties of 3 clinical balance measures, the Berg Balance Scale (BBS), the Balance subscale of the Fugl-Meyer test (FM-B), and the Postural Assessment Scale for Stroke Patients (PASS), in stroke patients with a broad range of neurological and functional impairment from the acute stage up to 180(More)
P. F. MacNeilage, M. G. Studdert-Kennedy, and B. Lindblom (1987) proposed a progression for handedness in primates that was supposed to account for the evolution of a right bias in human handedness. To test this proposal, the authors performed meta-analyses on 62 studies that provided individual data (representing 31 species: 9 prosimians, 6 New World(More)
BACKGROUND AND PURPOSE Prediction of activities of daily living (ADL) functions at an early stage after a stroke is critical because it enables clinicians to set treatment programs and goals. The objective of this study was to assess the relationship between trunk control at an early stage and comprehensive ADL function (as assessed by combining basic ADL(More)
BACKGROUND AND PURPOSE The 50-item Fugl-Meyer motor scale (FM) is commonly used in outcome studies. However, the lengthy administration time of the FM keeps it from being widely accepted for routine clinical use. We aimed to develop a short form of the FM (the S-FM) with sound psychometric properties for stroke patients. METHODS The FM was administered to(More)
