A shortened version of the ABC 16-item scale (ABC-16), the ABC-6, has been proposed as an alternative balance confidence measure. We investigated whether the ABC-6 is a valid and reliable measure of balance confidence and examined its relationship to balance impairment and falls in older adults. Thirty-five community-dwelling older adults completed the ABC-16, including the six questions of the ABC-6. They also completed the following clinical balance tests: unipedal stance time (UST), functional reach (FR), Timed Up and Go (TUG), and maximum step length (MSL). Participants reported twelve-month falls history. Balance confidence on the ABC-6 was significantly lower than on the ABC-16, however scores were highly correlated. Fallers reported lower balance confidence than non-fallers as measured by the ABC-6 scale, but confidence did not differ between the groups with the ABC-16. The ABC-6 significantly correlated with all balance tests assessed and number of falls. The ABC-16 significantly correlated with all balance tests assessed, but not with number of falls. Test-retest reliability for the ABC-16 and ABC-6 was good to excellent. The ABC-6 is a valid and reliable measure of balance confidence in community-dwelling older adults, and shows stronger relationships to falls than does the ABC-16. The ABC-6 may be a more useful balance confidence assessment tool than the ABC-16.
To be considered real change beyond the bounds of measurement error, change in 4-meter gait speed should exceed 10.8 cm/s (for intermediate speed ambulators) or 14.4 cm/s (for fast speed ambulators). Low measurement error in assessing 4-meter gait speed in community-dwelling older adults suggests that gait speed assessed over short distances has excellent reproducibility across trials. Low minimum change values suggest that 4-meter gait speed may be responsive and sensitive to change.
OBJECTIVE
We attempted to determine whether multimedia fall prevention education using different instructional strategies increases older adults’ knowledge of fall threats and their fall prevention behaviors.
METHOD
Fifty-three community-dwelling older adults were randomized to two educational groups or a control group. Multimedia-based educational interventions to increase fall threats knowledge and encourage fall prevention behaviors had two tailoring strategies: (1) improve content realism for individual learners (authenticity group) and (2) highlight program goals and benefits while using participants’ content selections (motivation group). Knowledge was measured at baseline and 1-mo follow-up. Participants recorded prevention behaviors for 1 mo.
RESULTS
Intervention group participants showed greater knowledge gains and posttest knowledge than did control group participants. The motivation group engaged in more prevention behaviors over 1 mo than did the other groups.
CONCLUSION
Tailoring fall prevention education by addressing authenticity and motivation successfully improved fall threats knowledge. Combining motivational strategies with multimedia education increased the effectiveness of the intervention in encouraging fall prevention behaviors.
OBJECTIVE
Fear of falling can lead to restricted activity, but little is known about how this fear affects different aspects of people’s lives. This study examined the relationship between fall-related efficacy (i.e., confidence or belief in one’s ability to perform activities without losing balance or falling) and activity and participation.
METHOD
We conducted a meta-analysis of studies comparing community-dwelling older adults’ fall-related efficacy to measures of activity or participation.
RESULTS
An examination of 20 cross-sectional and prospective studies found a strong positive relationship between fall-related efficacy and activity (r = .53; 95% CI [.47, .58]). An insufficient number of studies examining fall-related efficacy and participation were available for analysis.
CONCLUSION
Low fall-related efficacy may be an important barrier to occupational engagement for many older adults and warrants careful consideration by occupational therapists. Future research should explore interventions that target fall-related efficacy and examine their effects on activity performance and engagement.
Among older adults with OA, a bout of standardized physical activity resulted in increased fatigue and reduced activity, but effects were short-lived. Future studies will need to identify factors that differentiate people who are particularly fatigable in order to target interventions.
Huntington disease (HD) is a disorder characterized by chorea, dystonia, bradykinesia, cognitive decline and psychiatric comorbidities. Balance and gait impairments, as well as falls, are common manifestations of the disease. The importance of compensatory rapid stepping to maintain equilibrium in older adults is established, yet little is known of the role of stepping response times (SRTs) in balance control in people with HD. SRTs and commonly-used clinical measures of balance and mobility were evaluated in fourteen symptomatic participants with HD, and nine controls at a university mobility research laboratory. Relative and absolute reliability, as well as minimal detectable change in SRT were quantified in the HD participants. HD participants exhibited slower SRTs and poorer dynamic balance, mobility and motor performance than controls. HD participants also reported lower balance confidence than controls. Deficits in SRT were associated with low balance confidence and impairments on clinical measures of balance, mobility, and motor performance in HD participants. Measures of relative and absolute reliability indicate that SRT is reliable and reproducible across trials in people with HD. A moderately low percent minimal detectable change suggests that SRT appears sensitive to detecting real change in people with HD. SRT is impaired in people with HD and may be a valid and objective marker of disease progression.
OBJECTIVE
We examined the effects of a tailored activity-pacing intervention on self-perceived joint stiffness in adults with osteoarthritis (OA).
METHOD
Thirty-two adults with hip or knee OA were randomized to a tailored or general activity-pacing intervention. Participants’ symptoms and physical activity over 5 days were used to tailor activity pacing. The outcome was self-perceived joint stiffness measured at baseline, 4 wk, and 10 wk. A linear mixed regression model was used.
RESULTS
The tailored group significantly improved in stiffness compared with the general group over time. We found a significantly different linear trend between groups (Time × Group, p = .046) in which the tailored group had decreasing stiffness over the three time points, denoting continued improvement. The general group’s stiffness improved from baseline to 4 wk but returned to baseline levels at 10 wk.
CONCLUSION
Tailoring activity pacing may be effective in sustaining improvements in self-perceived joint stiffness in adults with OA.
