Fig 1.
Representative wounds from sham, 2-mT and 10-mT PEMF groups on post-wounding day 0, 3, 5, 7, 10, 14 and 21.
The area of wounds of the 2-mT PEMF group was slightly smaller on day 3. All photographs were taken with a 20 mm × 20 mm scale. Scale bar: 10 mm.
Fig 2.
Wound area and percentage wound area measured from sham, 2-mT and 10-mT PEMF groups on post-wounding day 0, 3, 5, 7, 10, 14 and 21.
Data are expressed as mean ± s.e.m. The % wound area of the 2-mT PEMF group was significantly smaller than that of the sham PEMF group (p = 0.036). * p < 0.05. The data used to plot this figure can be found in S1 Data.
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.
Fig 4.
Thickness of wounds 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 on day 3, 5, 14 and 21. Overall, the 10-mT PEMF group tended to have greater wound thickness 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.
