PubMed Commons is an experimental system of commenting on PubMed abstracts, introduced in October 2013. Comments are displayed on the abstract page, but during the initial closed pilot, only registered users can read or post comments. Any researcher who is listed as an author of an article indexed by PubMed is entitled to participate in the pilot. If you would like to participate and need an invitation, please email, giving the PubMed ID of an article on which you are an author. For more information, see the PubMed Commons FAQ.

Some more precision on the manuscript.

We have recently noticed some additional errors on the manuscript. Though these errors do not change the results and their interpretation, we would like to indicate them to the readers in order to better clarify our work.

  • In the caption below Figure 1, the second and third sentences should read "Although differences in performance between the groups can be seen in most directions, only the anterior direction reached the adjusted level of statistical differences (0.00625 (0.05/8 directions)). B)The COPlength represents the length of the COP trajectory from the starting position to the maximal position in a given direction. Individuals with SCI had significantly longer COPlength in all but two directions (0 and 180°) as compared to able-bodied individuals.
  • In the discussion section, in the paragraph starting with "Contrary to our initial hypothesis,", the 7th sentence should read "More specifically, individuals with SCI had greater COPmax in lateral and posterior directions while able-bodied individuals had greater COPmax in anterior and antero-lateral directions.
  • In the second sentence of the conclusion, "COPmax" should be replaced by "COPlength".

We apologize for the inconvenience that these errors may have caused.
