Age-related declines in postural control and physical fitness are strong risk factors for falls in older adults. Balance efficacy has been utilized to identify poor postural control, reduced physical function, and fall risk. However, it is not clear as to whether balance efficacy is truly a better predictor of functional fitness outcomes or postural control. Distinguishing these associations is an important step in the future derivation of physiotherapeutic programming to remediate acute and chronic decline. Therefore, the purpose of this cross-sectional study was to partition which measures are more associated with balance efficacy, fitness, or postural control. One hundred eleven community-dwelling older adults participated and were asked to complete the Balance Efficacy Scale (BES), a functional fitness measure (the Senior Fitness Test [SFT]), and a measure of postural control (the Sensory Organization Test [SOT]).We found that the SFT was more significantly associated with balance efficacy (R 2 = .37) than the SOT (R 2 = .08) in older adults. Overall, aerobic endurance, functional mobility in the SFT, and the vestibular score on the SOT were significantly associated with balance efficacy.We concluded that clinicians utilizing the BES as a preliminary screen should recommend physiotherapy follow-up activities that build endurance (walking), lower extremity functional mobility (sit-to-stand), and vestibular function (head movement while walking). Understanding the links between a preliminary screening tool and the physiological needs of the patient will allow for targeted activities to be prescribed.

It includes measurements of strength (i.e., chair stand, arm curl), flexibility (i.e., chair sit-and-reach, shoulder stretch), endurance (i.e., 6-min walk, 2-min step test), and functional mobility (i.e., 8-foot up-and-go). Moreover, the Sensory Organization Test (SOT) has been regarded as an important measurement tool used to examine and understand postural control through the integration of visual, somatosensory, and vestibular components (Jacobson, Newman, & Kartush, 1993).Previous studies have found that balance efficacy is related to functional fitness (Klima, Newton, Keshner, & Davey, 2012;Woollacott & Shumway-Cook, 2002) and postural control (Arnold & Faulkner, 2009). For example, Klima et al. (2012) found that balance efficacy is significantly correlated with balance ability and functional mobility in community-dwelling older men. Other researchers have found aerobic endurance is strongly related to balance efficacy in older adults (Julius, Brach, Wert, & VanSwearingen, 2012). Moreover, it has been found that balance efficacy is an independent predictor of balance performance in challenging sensory conditions (Arnold & Faulkner, 2009;Liu-Ambrose et al., 2006). However, according to Lane et al. (2014), balance performance scores from the SOT did not sh...
