It depends why you are doing the post hoc test and what you want to control, but assuming you have a fairly small number of p values and you are treating these all the same (i.e., you aren't treating, for example those involving a control group differently), then Holm's procedure has good properties.

Dear Aminu A. Ibrahim ,

As Friedman's ANOVA is a nonparametric technique its post hoc tests will work irrespective of the data type of your dependent variable.
