Grab-bars and transfer poles are common sit-to-stand aids for older adults with mobility limitations. This study investigates differences in kinematics and kinetics in the lower limbs across different transfer pole configurations and positions. Configurations tested are a single pole, two poles and a pole with a horizontal grab-bar at near and far positions. Three-dimensional biomechanics were used to calculate kinetics and kinematics of the lower extremities. Forces were also recorded from the pole. This study found horizontal pole forces were an effective replacement for trunk generated horizontal momentum. Reduced vertical pole forces were applied by participants using the `far' poles which resulted in increases in non-dominant hip moments when using the single and double pole configurations. Horizontal pole use introduced non-dominant directed lateral COM trajectory throughout the movement. This coincided with increased horizontal forces in the dominant foot to balance moments about COM in the transverse plane as a motor control strategy.

Despite the perceived importance of grab bars to facilitate aging-in-place and healthy aging, many community-dwelling older adults do not have them installed. The aim of this study was to investigate predictors of grab bar installation among well-educated community dwelling seniors. Data was collected quantitatively through an electronic survey of Oregon residents 50 years of age and older. The research analysis was completed using logistic regression with SPSS and qualitative analysis for the open questions. / Graduation date: 2012
