I have two within subjects factors. One variable is fatigue (baseline, fatigue, rest). The other variable is the amplitude of swallowing muscle activity (T_tot_d when baseline, when subjects are fatigued, _tot_d after subjects rested). In my opinion, two way repeated measures MANOVA have one within-subject factor and one between-subject factor. In this case, I have two within-subjects factor groups. Is it possible for me to do MANOVA with these 2 within-subjects factors? If so, how?
