Gait Speed and Frailty Status in Relation to Adverse Outcomes in Geriatric Rehabilitation.

Objective: Both slow gait speed (GS) and higher levels of frailty are associated with adverse outcomes in community-dwelling older people. However these measures are not routinely utilized to stratify risk status in the hospital setting. Here we assessed their predictive validity in older inpatients.

Feasibility and validity of frailty measurement in geriatric rehabilitation.

Objectives: The measurement of frailty using a Frailty Index (FI) has been criticised as too time-consuming for use in hospital settings. We aimed to assess the feasibility and characteristics of an FI derived from routinely collected data.

Methods: A total of 258 participants aged 65 and older were included in a single-centre prospective cohort study conducted in inpatient geriatric rehabilitation wards.

Assessing frontal behavioral syndromes and cognitive functions in traumatic brain injury.

This study examined the relationship between individual and family ratings on a measure of frontal behaviors using the Frontal Systems Behavior Scale (FrSBe). Additionally, this study investigated whether self-reported symptoms of frontal-lobe dysfunction correspond to neuropsychological performance, particularly those tests measuring executive functions. Thirty-three individuals with moderate-to-severe traumatic brain injury (TBI) and 19 healthy individuals completed the FrSBe and neuropsychological measures.

Examination of cognitive fatigue in multiple sclerosis using functional magnetic resonance imaging and diffusion tensor imaging.

The present study investigated the neural correlates of cognitive fatigue in Multiple Sclerosis (MS), looking specifically at the relationship between self-reported fatigue and objective measures of cognitive fatigue. In Experiment 1, functional magnetic resonance imaging (fMRI) was used to examine where in the brain BOLD activity covaried with "state" fatigue, assessed during performance of a task designed to induce cognitive fatigue while in the scanner. In Experiment 2, diffusion tensor imaging (DTI) was used to examine where in the brain white matter damage correlated with increased "trait" fatigue in individuals with MS, assessed by the Fatigue Severity Scale (FSS) completed outside the scanning session.
