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)
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)
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)
Handedness is an aspect of hemispheric specialization whose pattern of expression may signal an unusual specialization that in turn, may underlie several developmental psychopathologies. It is generally believed that infant handedness is neither stable nor reliable and hence, cannot be used as an early marker of potential developmental abnormality of(More)
Handedness for acquiring objects was assessed monthly from 6 to 14 months in 328 infants (182 males). A group based trajectory model identified 3 latent groups with different developmental trajectories: those with an identifiable right preference (38%) or left preference (14%) and those without an identifiable preference (48%) but with a significant trend(More)
BACKGROUND The minimal clinically important difference (MCID) of the Stroke Rehabilitation Assessment of Movement (STREAM) measure is unknown, which limits the application and interpretation of change scores. OBJECTIVE To estimate the MCID of the 3 subscales (ie, lower extremity, upper extremity, and mobility subscales) of the STREAM using the method of(More)
OBJECTIVE To examine the effect of spoon-handle size on kinematic performance in people with Parkinson's disease. DESIGN A counterbalanced repeated-measures design. SETTING A motor control laboratory in a university setting. SUBJECTS Eighteen individuals with Parkinson's disease and 18 age-matched controls. EXPERIMENTAL CONDITIONS: Each participant(More)
Infant hand-use preferences for apprehending objects were assessed three times at 7, 9, and 11 months of age for 154 infants (79 males) using a reliable and valid procedure. Two classification procedures (differing in Type I classification error rates) were used to identify an infant's preference (right, left, no preference) at each age, and these data were(More)
Twenty-five infants, divided into three approximately equal groups according to their hand-use preference for reaching for and grasping objects (right, left, or no-preference), were videotaped at 7 and 11 months while involved in a semiplay activity in which they were presented with 26 toys (20-40 s for each presentation). Unimanual manipulation activity(More)
BACKGROUND/PURPOSE To investigate the psychometric properties (acceptability, internal consistency reliability, interrater reliability, construct validity) and identify the most challenging items of the Berg Balance Scale (BBS) for elderly people living in the community. METHODS A total of 268 community-dwelling adults 65 years of age or older volunteered(More)
