In this paper, we present a preliminary study of how this technology can be applied in order to improve performance during standing to help the user to keep balance under perturbations. Non-impaired users wearing a hand exoskeleton gripping a hand rail were pushed by a cable-driven robot, so that their standing equilibrium was perturbed. The center of pressure, surface electromyography, and interaction force data were recorded in order to assess the performance of users and their postural strategy. The results showed that users could keep their balance with the same outcomes using their bare hands and the hand exoskeleton. However, when wearing the exoskeleton, a higher muscular activity was registered in hand flexor muscles. This is also supported by the grasping force, which shows that users stretched their hand more than expected when wearing the hand exoskeleton. This paper concludes that it is possible that the lack of tactile feedback could lead to over compensation in the grasping. Therefore, the next studies will aim to check whether this effect can be reversed by training users to wear the exoskeleton.<\/jats:p>","DOI":"10.3390\/s21010030","type":"journal-article","created":{"date-parts":[[2020,12,23]],"date-time":"2020-12-23T12:19:51Z","timestamp":1608725991000},"page":"30","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":5,"title":["Exploring New Potential Applications for Hand Exoskeletons: Power Grip to Assist Human Standing"],"prefix":"10.3390","volume":"21","author":[{"given":"Jorge A.","family":"Diez","sequence":"first","affiliation":[{"name":"Biomedical Neuroengineering Group, Universidad Miguel Hern\u00e1ndez, 03202 Elche, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Victor","family":"Santamaria","sequence":"additional","affiliation":[{"name":"Robotics and Rehabilitation Laboratory, Columbia University, New York, NY 10027, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Moiz I.","family":"Khan","sequence":"additional","affiliation":[{"name":"Robotics and Rehabilitation Laboratory, Columbia University, New York, NY 10027, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3608-1039","authenticated-orcid":false,"given":"Jos\u00e9 M.","family":"Catal\u00e1n","sequence":"additional","affiliation":[{"name":"Biomedical Neuroengineering Group, Universidad Miguel Hern\u00e1ndez, 03202 Elche, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2510-3829","authenticated-orcid":false,"given":"Nicolas","family":"Garcia-Aracil","sequence":"additional","affiliation":[{"name":"Biomedical Neuroengineering Group, Universidad Miguel Hern\u00e1ndez, 03202 Elche, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Sunil K.","family":"Agrawal","sequence":"additional","affiliation":[{"name":"Robotics and Rehabilitation Laboratory, Columbia University, New York, NY 10027, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2020,12,23]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"140","DOI":"10.1109\/TOH.2015.2417570","article-title":"An EMG-Controlled Robotic Hand Exoskeleton for Bilateral Rehabilitation","volume":"8","author":"Leonardis","year":"2015","journal-title":"IEEE Trans.
