Value of the Data •Data are useful to support the investigation of low-cost devices for posture analysis, which could be used in clinical environments for a smart evaluation of balance capabilities in different kind of population. •Researchers can benefit from these data to check and analyze the quality of the Nintendo Wii Balance Board force signals and derived measures by a direct comparison with the gold-standard device for posture analysis. •These data can be used to compare the quality of the Nintendo Wii Balance Board for kinetic measures made during motor tasks different from the unperturbed balance maintenance. •An additional value of these data is that they were acquired simultaneously from the two devices, allowing a direct comparison between a low-cost device and the gold-standard device for kinetic measures.
