Gender Differences In Neighborhood Walking In Older Adults, N. A. Gallagher, P. J. Clarke, Kimberlee A. Gretebeck

College of Nursing Faculty Research and Publications

Objective: This study examined mobility, self-efficacy, outcome expectations, neighborhood (density, destinations, and design), and neighborhood walking in older men (n = 106, 60-99 years, M = 76.78, SD = 8.12) and women (n = 216, 60-99 years, M = 75.81, SD = 8.46).

Method/Results: In hierarchical regression, the variables explained 32% of the variance in neighborhood walking in men (p < .001) and 27% of the variance in women (p < .01). Self-efficacy (β = .49, p < .01), density (β= .22, p < .05), and design (β= .21, p = .05) were associated with walking in men. Significant design characteristics included sidewalks (β= .25, p < .05) and crime (β= .36, p < .01). In women, self-efficacy (β= .48, p < .001) and destinations (β= .15, p < .05) were associated with walking. Walking was associated with self-efficacy for walking despite individual barriers in women (β= .38, p < .001) and neighborhood barriers in men (β= .30, p < .05).

Conclusion: Walking interventions targeting older women should incorporate local destinations. In older …

Adult-Acquired Flatfoot Deformity And Age-Related Differences In Foot And Ankle Kinematics During The Single-Limb Heel-Rise Test, Ruth L. Chimenti, Joshua Tome, Cody D. Hillin, Adolph S. Flemister, Jeff Houck

Faculty Publications - College of Physical Therapy

STUDY DESIGN: Cross-sectional laboratory study.

OBJECTIVE: To compare single-limb heel-rise performance and foot-ankle kinematics between persons with stage 2 adult-acquired flatfoot deformity (AAFD) and healthy controls.

BACKGROUND: The inability to perform a single-limb heel rise is considered a positive functional diagnostic test for AAFD. However, which foot motions contribute to poor performance of this task are not known.

METHODS: Fifty individuals participated in this study, 20 with stage 2 AAFD (mean +/- SD age, 57.6 +/- 11.3 years), and 15 older participants (age, 56.8 +/- 5.3 years) and 15 younger participants (age, 22.2 +/- 2.4 years) without AAFD as control …

Concurrent Validity Of Accelerations Measured Using A Tri-Axial Inertial Measurement Unit While Walking On Firm, Compliant, And Uneven Surfaces, Michael H. Cole, Wolbert Van Den Hoorn, Justin K. Kavanagh, Steven Morrison, Paul W. Hodges, James E. Smeathers, Graham K. Kerr

Rehabilitation Sciences Faculty Publications

Although accelerometers are extensively used for assessing gait, limited research has evaluated the concurrent validity of these devices on less predictable walking surfaces or the comparability of different methods used for gravitational acceleration compensation. This study evaluated the concurrent validity of trunk accelerations derived from a tri-axial inertial measurement unit while walking on firm, compliant and uneven surfaces and contrasted two methods used to remove gravitational accelerations; i) subtraction of the best linear fit from the data (detrending); and ii) use of orientation information (quaternions) from the inertial measurement unit. Twelve older and twelve younger adults walked at their preferred …

Taking Physical Activity To The Streets: The Popularity Of Ciclovia And Open Streets Initiatives In The Us, J. Aaron Hipp

Brown School Faculty Publications

As a way to reduce chronic diseases associated with increasingly sedentary lifestyles, the Centers for Disease Control and Prevention advocates community-wide initiatives promoting physical activity. One such initiative gaining popularity in the US is the Ciclovía, or Open Streets initiative, where city streets are opened to residents for physical activity and closed to motorized traffic.1 Open Streets gained international prominence in Bogota, Colombia, and are viewed by policy makers and health and community advocates as being beneficial to social, environmental, and community health.2 The interest in initiatives is demonstrated by the increase in the number of events within and across …
