Testing a backward figure-of-eight walk to check balance in older adults

Mobility is a fundamental element of healthy aging. Balance is a necessary function during mobility for all movements throughout life in elderly individuals. Falls due to balance disorders in elderly individuals cause a decrease in the quality of life. Studies in the literature indicate that 13% of individuals aged 65-69 experience falls, and this rate rises to 46% in individuals over 85. Lower extremity muscle volume and strength gradually decrease with aging. This decreased muscle strength directly impacts individuals' activities of daily living.Normal walking speed for elderly individuals is related to balance and overall health performance. However, walking assessments generally focus on walking activities in a forward direction and in a straight line. However, in daily life, we may need to sit on a chair, walk backward to navigate a narrow space, or change direction suddenly due to obstacles or environmental cues. Walking backward requires more complex motor control, and these gait training programs are known to be effective in improving balance and walking skills.Clinically, balance assessments in the elderly persons are commonly measured by using the TUG, 10-meter walk test, functional reach test, 4-square step test, and Berg balance scale. The methods used to assess balance are still not fully standardized. The best test for assessing dynamic balance and fall risk is still up for debate, especially when it comes to elderly individuals who live freely in the community. Further research is needed to determine whether lateral walking tests can identify those at high risk of falling in elderly adults. The purpose of this study was to determine the reliability, validity, and minimal detectable change (MDC) of the Figure-of-8 backward walking test in healthy elderly adults.
