ABSTRACT This observational study investigated the relationship between balance, mobility and falls in 72 hemiplegic stroke inpatients, with the aim of developing a model for predicting fall risk. Fall history was recorded by interview, balance was assessed using the Berg Balance Scale (BBS) and activities of daily living were evaluated using the Functional Independence Measure (FIM). Variables differing between fallers and non-fallers were identified, and a stepwise regression analysis was performed to identify a combination of variables that effectively predicted fall status. Fallers (occasional and repeat; n = 27) had a shorter time from stroke onset, lower FIM scores on admission and discharge, lower BBS and Mini-Mental State Examination scores, a greater age and longer length of hospital stay compared with non-fallers (all differences were significant). A logistic model for predicting falls showed that BBS at admission was significantly related to falls, with fallers having lower BBS scores at admission (cut-off <or= 29; sensitivity 80%; specificity 78%). These data suggest BBS is a sensitive and specific measure for identifying stroke patients at risk of falling.

    ABSTRACT: Dizziness and impaired balance are common complaints after traumatic brain injury as a result of injuries to many systems. Ambient visual and vestibular system impairments are strong contributors to imbalance and dizziness, often leading to problems with spatial orientation and gaze stability during movement. The purpose of this review is to provide an overview of visual-vestibular impairments common to traumatic brain injury and summarize the contribution impairments in these systems will have on higher-level mobility. Standard visual and vestibular tests and measures are described and summarized, followed by several case presentations discussing the examination and evaluation processes and interventions chosen for visual-vestibular difficulties and their relationship to higher-level mobility.

    ABSTRACT: To determine the concurrent validity of the Balance Outcome Measure for Elder Rehabilitation (BOOMER) with both the Berg Balance Scale (BBS) and gait speed. Prospective cohort study. Two geriatric rehabilitation units. Elderly adults (N=134) admitted to inpatient rehabilitation. Not applicable. The BOOMER consists of timed static stance feet together eyes closed, Functional Reach, step test, and the Timed Up and Go test. Validity was determined using the Spearman correlation coefficient, comparing the BOOMER with the BBS and gait speed on admission and discharge. Responsiveness of the BOOMER was compared with the BBS and gait speed for the change scores between admission and discharge using the Spearman correlation coefficient. The BOOMER demonstrated high to very high correlation with the BBS at admission (ρ=.91; P<.01) and discharge (ρ=.89; P<.01), and with gait speed at admission (ρ=.67; P<.01) and discharge (ρ=.68; P<.01). Change scores between admission and discharge for the BOOMER and BBS displayed moderate correlation (ρ=.55; P<.01), while those between the BOOMER and gait speed displayed only fair correlation (ρ=.33 P<.01). The BOOMER appears to be a valid measure of the standing balance construct because it demonstrated high correlation with another measure of balance, and moderate correlation with a measure of a related construct (gait speed). The BOOMER may be a worthwhile alternative for more complex multi-item balance measures.
