After publication of the original article [1], it came to the authors’ attention that there was an error in the Methods/Design section.In the Participants sub-section, the following sentence was incorrect: “However, persons who do not speak the Norwegian language will be excluded, as will those with cognitive dysfunction or with other diseases or injuries that may negatively impact hand function”.This should have read: “However, persons who do not speak the Norwegian language will be excluded, as will those with cognitive dysfunction”.
