Background: The principles of motor learning (PML) emerged from studies of limb motor skills in healthy, young adults. The applicability of these principles to speech motor learning, and to older adults, is uncertain.
Aims: The purpose of this study was to examine one PML, feedback frequency, and its effect on retention and generalization of a novel speech and comparable tracing task.
Methods: Sixty older adults completed a speech motor learning task requiring the production of a novel phrase at speaking rates 2 times and 3 times slower than habitual rate. Participants also completed a limb motor learning task requiring the tracing of a sine wave 2x and 3x slower than habitual rate. Participants were randomly assigned to receive feedback every trial, every 5th trial, or every 10th trial. Mean absolute error was measured to examine immediate generalization, delayed generalization, and 2-day retention.
Findings: Results suggested that feedback frequency did not have an effect on the retention and generalization of the speech or manual task, supporting the small but growing literature highlighting the constraints of generalizing the PML to other modalities and populations.

Elderly falls are a healthcare epidemic. We aimed to identify risk factors of serious falls by linking data on functional status from the Global Longitudinal Study of Osteoporosis in Women (GLOW) and our institutional trauma registry. 124 of 5,091 local women enrolled in GLOW were evaluated by our trauma team for injuries related to a fall during the study period. Median injury severity score was 9. The most common injuries were intertrochanteric femur fracture (n = 25, 9.8%) and skin contusion/hematoma to face (n = 12, 4.7%). Injured women were older than the uninjured cohort (median 80 versus 68 years), more likely to have cardiovascular disease and osteoarthritis, and less likely to have high cholesterol. Prospectively collected Short Form 36 (SF-36) baseline activity status revealed greater limitation in all assessed activities in women evaluated for fall-related injuries in our trauma center. In multivariable analysis, age (per 10 year increase) and two or more self-reported falls in the baseline survey were the strongest predictors of falling (both HR 2.4, p <0.0001 and p<0.001 respectively), followed by history of osteoarthritis (HR 1.6, p= 0.01). Functional status was no longer associated with risk of fall when adjusting for these factors. Functional status appears to be a surrogate marker for frailty. With the aging of the US population and long lifespan of American women, this finding has important implications for both fall prevention strategies and research intended to better understand why aging women fall as burdensome validated metrics may not be the best indicators of fall risk.
