“…More interestingly, the study revealed poor construct validity between measures, indicating that the selected methods of balance assessment examine unrelated constructs. This supports previous findings by Almeida et al that identified no significant correlation between the Y Balance Test and the Biodex SI. These findings support the growing body of evidence that the constructs of balance and postural stability are complicated and involve a series of unique motor systems that require a focused examination by a skilled clinician.…”

“…These two components of human performance serve as a foundation of stability prior to achieving more complex controlled mobility and skilled activities such as independent standing and walking . Postural control, or stability, represents an individual's capacity to maintain an upright position during both static and dynamic conditions, with or without the application of external perturbation or displacement of support surface . Posture is an angular measure from vertical describing the gravitational vector of the body's orientation .…”

“…However, its ability to provide an accurate representation of balance parameters is very limited in comparison to that of functional performance measures widely used now, such as the FSST and TUG . Research demonstrated that the Biodex SI was not correlated to the Y Balance Test in individuals with or without lower limb injuries . Commonly used rehab tools, such as the FSST and TUG, may be the most efficient and most accurate representation of a patient's balance; however, with the introduction of new technology, such as the Biodex Stability System, clinicians and researchers should examine if an update in standard of care is needed.…”

ObjectivesThe Biodex SD Stability System has been shown to be a reliable assessment tool for postural stability. However, its ability to provide an accurate representation of balance has not been compared with functional performance measures such as the four‐square step test (FSST) and timed‐up‐and‐go test (TUG). The purpose of this study was to investigate reliability, internal consistency, and construct validity of FSST, TUG, and Biodex SD (limits of stability [LOS] and modified Clinical Test of Sensory Organization and Balance [m‐CTSIB]).MethodsAn observational reliability and validity study was conducted. A convenience sample of 105 healthy adults, 77 females and 28 males, mean age 24.5 years old (± 4.66 SD) performed balance assessments including the FSST, TUG, Biodex SD LOS, and m‐CTSIB. For LOS, the overall percentage and test duration were recorded. For m‐CTSIB, the overall Sway Index was recorded. Condition 1 of the m‐CTSIB represented simple postural stability.ResultsThe Biodex SD LOS overall percentage, TUG, and FSST showed strong to excellent test‐retest reliability (ICC [3, 1] = .83 [mean 1: 58.14, mean 2: 60.54], .88 [mean 1: 6.98 seconds, mean 2: 6.91 seconds], .92 [mean 1: 6.29 seconds, mean 2: 6.14 seconds], respectively), while the Biodex SD m‐CTSIB overall percentage demonstrated strong test‐retest reliability (ICC [3, 1] = .75 [mean 1: 1.18, mean 2: 1.18]). The LOS test duration showed moderate test‐retest reliability (ICC [3, 1] = .58 [mean 1: 38.55 seconds, mean 2: 37.10 seconds]), while the m‐CTSIB condition 1 showed poor test‐retest reliability (ICC [3, 1] = .24 [mean 1: 0.63, mean 2: 0.66]). Weak construct validity was found between TUG, FSST, and Biodex SD measures of LOS and m‐CTSIB (r values = −0.15‐0.22).ConclusionIt is suggested that clinicians use more than one measure to assess different aspects of a patient's balance deficits to better guide treatment and intervention.

BACKGROUND: To avoid injuries in basketball players, they are recommended to pay more attention to improve their body balance. Therefore new training methods and equipment need to be devised. This study examined the effects of an 8-week basketball-specific proprioception training program while using a new developed one plane instability balance board during warm-up for improving balance ability in basketball players. Players who obtained basketball-specific balance training were compared to a control group. METHODS: Thirty-one male university basketball players (age: 21.35, SD = 0.605 years; height: 190.97, SD = 1.88; body mass: 86.95, SD = 2.61) participated in this study. Seventeen participants were assigned to the basketball-specific 8-week balance training group (BTG) while 14 participants served as a control group (CG). Both groups were tested with the Y balance test (YBT) and postural stability test (PST) at baseline and 8 weeks later. RESULTS: The results indicate significant improvements in the overall YBT for both legs in BTG, but not in CG. However, no group differences were found for dynamic balance performance, but static balance (i.e., postural stability) differed between groups after 8 weeks. A statistically significant moderate inverse correlation was computed between the total score of YBT and the total score of the overall stability index (r=-0.404; p= 0.041). CONCLUSIONS: An 8-week basketball-specific proprioception training program with a single-plane instability balance platform improved balance ability (Y balance test and postural stability test) of basketball players.

“…Les valeurs de corrélations sont modérées à bonne (r=0.57 à 0.78) [2]. Le YBT est peu corrélé avec la berg balance scale (BBS) chez les personnes âgées [11], et le test d'équilibre statique monopodal chez des sportifs loisirs [18].…”

Y balance test has no correlation with the Stability Index of the Biodex Balance System

Abstract: The results of this study showed the YBT is not correlated with the SI-BBS as an assessment of postural stability. This finding has implications for researchers and clinicians using YBT results as the only measure of postural stability.
