Resumen
The Wii Balance Board (WBB) began to be investigated as a low-cost alternative for
assessing static balance in vertical posture. However, studies employed methodological
procedures that did not eliminate result variability between the tests and equipment used.
Objective: Determine the validity and reproducibility of the WBB as an instrument for
assessing static balance in the vertical position, using simultaneous data analysis and
superimposed equipment. Methods: This is an accuracy study of 29 healthy young
individuals of both sexes aged 18 to 30 years. Subjects were assessed 24h apart (test-retest),
using unipodal and bipodal support tests, with eyes closed and open. To that end the WBB
was placed on top of a force platform (FP) and data (postural sway) were collected
simultaneously on both devices. Validity and reproducibility were analyzed using the
interclass correlation coefficient (ICC). Finally, Bland-Altman analysis was applied to assess
agreement. Results: The sample was composed of 23 women and 6 men, with mean age of
24.2±6.3 years, 60.7±6.3 kg and 1.64±4.2 m. The validity of the WBB compared to the FP
was excellent for all 4 tasks proposed (ICC = 0.93 0.98). The reproducibility analyzed by
test-retest was excellent for the bipodal support tasks (ICC = 0.93-0.98) and only moderate for
the unipodal support tests (ICC = 0.46 0.70). Graphic analysis exhibited good agreement
between the devices, since most of the measures were within the limits of agreement.
Conclusion: this study proved the validity and reproducibility of the Wii Balance Board as an
instrument for assessing static balance in vertical posture, using simultaneous analysis with
superimposed equipment. Thus, the WBB has been increasingly used by physical therapists
and other health professionals in their clinical practice, as both a rehabilitation and assessment
tool
