Abstract
ABSTRACTObjective: The objective of this study was to analyze the functional status of adult and older adult individuals with lower back pain . Methods: Eighty-three individuals were recruited, 42 older adults (20 with lower back pain and 22 control group) and 41 younger adults (21 with lower back pain and 20 control group). Functional capacity was assessed using the following tests: Timed Up and Go (TUG), Five Times Sit-to-Stand (FTSTS), six-minute walking test (SMWT), and sitting-rising test (SRT) . Results: In the younger adults, there was no difference in functional capacity between the groups (p>0.05). On the other hand, when statistical analysis was adjusted using body mass index (BMI) as a covariate, the lower back pain group performed more poorly on the SRT (p<0.004). Furthermore, poorer physical capacity was seen in the older adults with back pain via the SRT test (p=0.001), and when the BMI was adjusted, a statistical difference was seen in the SRT as well as the SMWT (p<0.05) . Conclusion: Older individuals with lower back pain have poorer physical performance, and the sitting-rising test is the most discerning for assessment of functional status in individuals with lower back pain. Level of Evidence III, Retrospective Comparative Study.
Highlights
Like a number of other developing countries, Brazil is undergoing a demographic shift, which is more evident in recent decades; the Brazilian population has been aging quickly since the early 1960s

The confidence interval was set at 95%, alpha level at 5% and test power at 80%, and a minimum sample of 16 individuals per group was required to test the null hypothesis that there is no difference between the sensory-motor properties of individuals with and without chronic lumbar pain
Summary
Like a number of other developing countries, Brazil is undergoing a demographic shift, which is more evident in recent decades; the Brazilian population has been aging quickly since the early 1960s. Functional capacity assessments can provide important information on the population with lumbar pain; this requires the use of instruments that assess motor function, muscle strength and aerobic resistance, flexibility, coordination, agility, and dynamic balance. These activities aim to ensure muscular and skeletal integrity in individuals, in the elderly population, helping to reduce the risk of falls and functional disability, and in individuals recovering from chronic conditions. The objective of this study was to evaluate the functionality of elderly and younger individuals with chronic lower back pain, and to identify which tests are most discerning in analyzing the functional status of these individuals
