Abstract

Falls are the leading cause of fatal and non-fatal injuries for older Americans. Modifying exercise programs to address balance and lower body strength would vastly improve stability and functional movement. Past literature has shown balance and strength are important in preventing falls, but few studies have focused on developing strength in a lateral plane compared to an anterior/posterior plane. PURPOSE: To determine if a lateral pedal recumbent training device that allows lower limb movement in a horizontal plane can improve balance scores among older adults in 4 weeks. METHODS: A two group experimental-control multivariate design was selected for the study. All subjects (n = 56) were between the ages of 59-80 years and without any physical limitations or medical issues. All participants were divided into 2 equal groups, pre-tested and post-tested on a computerized posturography plate (Bertec, Inc. Columbus, OH.) to determine Center of Pressure scores with eyes opened (EOSS), Center of Pressure scores with eyes closed (ECSS), Center of Pressure scores with eyes open perturbed surface (EOPS), and Center of Pressure scores with eyes closed perturbed surface (ECPS). The experimental group used the lateral trainer for 15 minutes, 3 times per week, for 4 consecutive weeks while the control group maintained a sedentary lifestyle. A repeated measures MANOVA was used to determine significance between the two groups within the 4 balance assessments. RESULTS: There were no significant main treatment effects for either group (p = .221). There were statistically significant differences over time for EOPS (p = .047) and ECPS (p = .047). Likewise, there were statistically significant differences for each univariate outcome with EOSS (p = .045) ECSS (p = .033), EOPS (p = .010), and ECPS (p = .026). Statistical power was achieved (> .98) for both univariate and multivariate measures. The multivariate outcome for group x time interaction accounted for 15.2% more variance than time alone (28.1%) for the experimental group alone. CONCLUSION: A recumbent lateral stability device can improve balance scores among older adults within 4 weeks of training, 3 x week for 15 minutes.
