In the original published version of this article, information pertaining to ethical approval, informed consent, and potential conflicts of interest was only partially noted. The authors have included this information below. This error has no implications for the reported results.

Ethical Approval The Scientific and Ethics committee of the Lega F. D’Oro, Osimo, Italy provided approval for the study. All procedures used during the study were in accordance with the ethical standards of the institutional and/or national research committee and with the 1964 Helsinki declaration and its later amendments or comparable ethical standards.

Informed Consent All three participants were apparently interested in using a technology device as the one evaluated in the study, and thus in being involved in the study. Their legal representatives, moreover, had provided a formal consent for their participation in the study.

Conflict of Interest The authors report no conflicts of interest. The authors alone are responsible for the content and writing of this article.
