Competing Interests

The authors have declared that no competing interests exist. Potential conflict of interests: Our project partners Bioservo Technologies AB and Hocoma AG were involved in the ironHand project (grant AAL-2013-6-134), and interested in commercializing the ironHand system. Alejandro Melendez- Calderon was with Hocoma AG at the time of the study, but is now with Cereneo AG, Switzerland. He does not receive any financial or personal benefits from Hocoma AG or any other source for the publication of this study. This does not alter our adherence to PLOS ONE policies on sharing data and materials.
