I agree with the LegakisL and achamess. We are also using log scale in our lab to show PWT (von Frey filaments) and LegakisL pointed out the most important reasons: normal distribution that allowed the use of parametric tests. Unfortunately, there are some referees that do not understand and in some revisions they ask to present the absolute  
values. We just published a paper (Sci Rep. 2016 May 27;6:26955. doi: 10.1038/srep26955) in which we presented both scales to attend the referee.
