Try using Wilcoxon Rank Sum Test since you are dealing with same population with same intervention. It will help you know the group that benefitted well from the intervention before and after.Wilcoxon or paired t tests are valid for one independent variable and one dependent variable.

For parametric test, you may use t test for two dependent samples while for non parametric test, use its equivalent called paired sample Wilcoxon signed rank test.
