OBJECTIVES To assess, within the context of Rasch analysis, (1) the internal validity and reliability of the Berg Balance Scale (BBS) in a sample of rehabilitation patients with varied balance abilities; and (2) the comparability of the BBS measures across different neurologic diseases. DESIGN Observational prospective study. SETTING Rehabilitation ward(More)
We evaluated subcortical and cortical somatosensory evoked potentials (SEPs) in response to posterior tibial nerve stimulation in 4 experimental conditions of foot movement and compared them with the baseline condition of full relaxation. The experimental conditions were: (a) active flexion-extension of the stimulated foot; (b) active flexion-extension of(More)
BACKGROUND Effective discharge planning is increasingly recognised as a critical component of hospital-based Rehabilitation. The BRASS index is a risk screening tool for identification, shortly after hospital admission, of patients who are at risk of post-discharge problems. AIM To evaluate the internal construct validity and reliability of the Blaylock(More)
OBJECTIVE To build a new activity-based, "bed to community", aetiology-independent measure of balance within the neurological rehabilitation setting by merging some existing scales. METHODS Balance scales were selected using a conceptual framework and subsequently administered to a convenience sample of adult patients with balance problems due to(More)
OBJECTIVE To evaluate the classic psychometric and clinical profile of the Unified Balance Scale, a novel Rasch-based measure of balance. METHODS The Unified Balance Scale was administered to 219 neurological patients (providing 302 observations) admitted to rehabilitation, together with: Timed Up & Go, 10-meters walking test, Functional Ambulation(More)
OBJECTIVES (1) To appraise, by the means of Rasch analysis, the internal validity and reliability of the Coma Recovery Scale-Revised (CRS-R) in a sample of patients with disorder of consciousness (DOC); and (2) to provide information about the comparability of CRS-R scores across persons with DOC across different settings and groups, including different(More)
AIM The aim of this study was to evaluate which neurological impairments on discharge from rehabilitation services are associated with a worse outcome in terms of health related-quality of life (HRQoL) one year after stroke. METHODS We enrolled 528 first-time stroke patients in a multicenter observational study involving 18 Italian inpatients(More)
BACKGROUND It is unclear whether the BBS is an effective tool for the measurement of early postural control impairments in patients with Parkinson's disease (PD). AIM The aim of this paper was to evaluate BBS' content validity, internal construct validity, reliability and targeting in patients with PD within the Rasch analysis framework. DESIGN(More)
