As you may know, we decline a substantial proportion of manuscripts without sending them to referees, so that they may be sent elsewhere without delay. In such cases, even if referees were to certify the manuscript as technically correct, we do not believe that it represents a development of sufficient scientific impact to warrant publication in Nature. These editorial judgements are based on such considerations as the degree of advance provided, the breadth of potential interest to researchers and timeliness.
In this case, we do not feel that your paper has matched our criteria for further consideration. We certainly have no doubt that your model will be of value to others seeking a deeper understanding of human gait; and we don’t question that the insights so obtained could be relevant in a variety of therapeutic and artificial contexts. But as the broader implications of your findings have yet to be elucidated, we are unable to conclude that the paper offers the sort of striking advance that would be likely to excite the immediate interest of Nature’s broader audience. We therefore feel that the paper would find a more suitable outlet in another journal.
Please be assured that this editorial decision does not represent a criticism of the quality of your work, nor are we questioning its value to others working in this area. We hope that you will rapidly receive a more favourable response elsewhere.
