1
Including bilateral stimulations, since these did not differ from ipsilateral stimulations.
2
t-test for two samples with unequal variances. Because the individual measurements within samples were not always independent (some were from the same gage under different modes of stimulation), levels of significance should be taken as indicating trends only.
3
Maximum values of strain for each mode of stimulation. Although there were 5–6 gages for each site, only a few modes of stimulation were recorded per gage.
4
Strain values with and without the bite block did not differ and were combined.
