Fig 3. Biomechanical properties measured from sham, 2-mT and 10-mT PEMF groups on post-wounding day 3, 5, 7, 10, 14 and 21.

Significant between-group differences were found in maximum load (2-mT vs. 10-mT) and energy absorption capacity (sham vs. 10-mT and 2-mT vs. 10-mT) on day 5, and in Young’s modulus (sham vs. 10-mT) on day 14. Overall, both PEMF groups (2-mT and 10-mT) tended to have smaller maximum stress than the sham group. Data are expressed as mean ± s.e.m. * p < 0.05. The data used to plot this figure can be found in S2 Data.
