Reliability of novel postural sway task test

Abstract: The purpose of this study was to examine the reliability of parameters obtained from a novel postural sway task test based on body movements controlled by visual feedback. Fifty-nine volunteers were divided into two groups. The first group consisted of young (n = 32, 16 females and 16 males, age: 25.2 3.4 years) and the second group of elderly individuals (n = 27, 17 females and 10 males, age: 75.7 6.9 years). Participants stood in parallel on a computer based stabilographic platform with the feet approximately a shoulder width apart, the toes slightly pointing outwards, the hands placed on the hips. The computer screen was placed approximately 1.5 meter from the platform at a height of subjects eyes. An instantaneous visual feedback of participants centre of pressure (COP) was given in a form of a blue cross visible on the screen. Participants were instructed to keep the blue cross driven by movements of their hips as close as possible to a predefined curve flowing on the screen. Out of the 6 parameters studied, only the average distance of COP from the curve line and the sum of the COP crossings through the curve line showed high reliability. Correlation between these two highly reliable parameters was -0.89. There was also a statistical difference (p<0.001) between young and elderly in both the average distance of COP from the curve line and the sum of the COP crossings through the curve. To conclude, the novel postural sway task provides a simple tool with relatively low time burden needed for testing. The suggested output parameters measured are highly reliable and easy to interpret

A novel device to preserve physical activities of daily living in healthy older people
Stefan Loefler, Nejc Šarabon, Helmut Kern, Wolfram Haslinger, Lisa Müller, Christian Raschner, 2015, original scientific article

Abstract: Objective: To determine the effectiveness of exercise in improving sensorimotor function and functional performance as crucial part of activities of daily living in healthy older adults. Design: RCT. Setting: Laboratory. Participants: 39 subjects (M = 71.8 years, range: 61%89 years). Intervention: Task oriented visual feedback balance training. Primary outcome measure: Timed up & go (TUG). Secondary outcome measures: Chair stand test (CST), self-paced walk test, maximum isometric torque, quiet stand posturography and dynamic balance (DB). Results: Post intervention comparison of the treatment group (TG) and control group (CG) showed better TUG (p < .01), CST (p < .001) and DB (p < .025) for the TG. Pre%post intervention comparison of the TG showed better clinically relevant outcomes in TUG (p < .001), CST (p < .001) and DB (p < .001). Conclusion: Active driven visual feedback balance training is effective in improving functional performance and dynamic balance in older adults.
