PRIMARY OBJECTIVE To determine if individuals with brain injury can modify heart rate variability (HRV) through biofeedback and, if so, enhance its pattern to improve emotional regulation and problem-solving ability. DESIGN A quasi-experimental design with repeated measures was employed. Thirteen individuals aged 23-63 years with severe brain injury(More)
While motor and cognitive impairments are common in Multiple Sclerosis (MS) patients, research concerning their relationship in this population has been limited. We aimed to evaluate cross-sectional associations between cognitive functions, walking speed, and falls in patients with MS. Through a retrospective chart review of 81 patients with MS, we examined(More)
BACKGROUND Cognitive impairments are common in individuals with MS and adversely affect functioning. Early detection of cognitive impairment, therefore, would enable earlier, and possibly more effective, treatment. We sought to compare self-reports with a short neuropsychological test as possible screening tools for cognitive impairment. METHODS One(More)
OBJECTIVE Cognitive dysfunction is prevalent in multiple sclerosis. As self-reported cognitive functioning is unreliable, brief objective screening measures are needed. Utilizing widely used full-length neuropsychological tests, this study aimed to establish the criterion validity of highly abbreviated versions of the Brief Visuospatial Memory Test -(More)
Multiple sclerosis (MS) is frequently accompanied by changes in verbal memory. We hypothesized that administering an abbreviated California Verbal Learning Test-II (CVLT-II) would detect verbal memory problems in MS accurately, thus serving as a potential screening tool. We performed receiver-operating-characteristic (ROC) analyses of three trials (trial 1,(More)
