For ambulatory time following five impacts, there was no treatment group or interaction effect however time post-injury showed a strong trend for significance ( F 3.067,54.44 = 2.620, P = 0.0588, Fig. 10 A).

In fact, 5x TBI (but not 1x TBI) mice displayed a mild trend towards increased swim speeds the day prior to the probe trial ( t 17 = 1.679, P = 0.1114, Additional file 1 : Fig.
Using ICP-MS we found a slight trend towards decreased total iron content in the ipsilateral hemisphere of the parietal cortex in 5x TBI animals versus Shams ( t 16 = 1.643, P = 0.1199, Fig. 5 J).
Post hoc analysis revealed a strong trend towards increased stance width at 3 months ( t 16.38 = 2.027, P = 0.0593), a small trend at 6 months ( t 17.98 = 1.517, P = 0.1467) and a significant increase at 9 months ( t 17 = 3.429, P = 0.0032) post-injury in 5x TBI animals versus Shams.
Taken together, this data suggests that five impacts causes on average an increase in ambulatory time, zone entries and vertical counts and a decrease in resting time, with the opposite trend occurring for the 1x TBI animals, but these data did not reach statistical significance.
