Low back pain (LBP) is common in the elders, and is the musculoskeletal disorder most commonly observed in those over the age of 75 years. LBP in the elders is a disabling health condition, which impacts negatively on their physical capacity of these individuals and is associated with negative consequences, such as increased number of falls. There is a gap in the literature relative to studies about LBP in older people, especially about disabling outcomes such as falls. Acute LBP involves mechanisms that may be related to increased risk of falls in the elders, such as pain inhibition mechanism that will lead to changes in balance. The assessment of fall risk in older adults is complex due to the multifactorial nature of underlying risk factors. The Physiological Profile Assessment (PPA) is one validated fall risk assessment tool that involves the direct assessment of sensorimotor abilities. The PPA contains five tests: visual contrast sensitivity, hand reaction time, quadriceps strength, lower limb proprioception and postural sway. The aim of this thesis was to compare the risk of falls and functionality in older adults with and without LBP and to investigate the association between clinical and functional factors and fall risk in the elders with acute LBP. A transversal study was conducted with 140 older adults (69.9 ± 5.2 years), it was a subsample of the epidemiological study Back Complaints in the Elders (BACE) Brazil. Fall risk was assessed by PPA short version; LBP was assessed by the numerical pain scale (NPS) and the McGill pain questionnaire; physical capacity was assessed using the Timed Up and Go (TUG) test, normal Walking Speed (WS) test, and Five Times Sit to Stand Test (5xSST); functional performance was assessed using the Roland Morris Disability Questionnaire. Fall efficacy was assessed by Falls Efficacy Scale-International-Brazil (FES-I-BRAZIL). The Geriatric Depression Scale was used for screening of depressive symptoms and the physical activity level was measured using the International Physical Activity Questionnaire (IPAQ)-Short. The results were presented in three studies. The first study evaluated the falls risk using the PPA in elderly patients with (n = 52) and without LBP (n = 52). The elders with LBP had a significantly higher overall fall risk (p < 0,001), greater postural sway (p < 0,001), longer reaction time (p < 0,001) and lower quadriceps strength (p = 0,02) in comparison to elders without LBP. There was no significant difference for the vision and proprioception tests between the two
