Total energy absorbed (N-mm)
Study	18,950.0 ± 3083.8	6869.0 ± 6598.1
Control	20,740.0 ± 5380.5	25,746.0 ± 3275.0
P value	0.268	< 0.001
Energy absorbed before peak load (N-mm)
Study	9515.4 ± 607.3	3117.7 ± 2819.3
Control	12,298.0 ± 3601.3	11,117.0 ± 2065.4
P value	0.063	< 0.001
Ratio of Energy Absorption Before Peak	Load (%)
Study	51.4 ± 10.1	48.7 ± 9.2
Control	59.3 8.46	43.3 ± 6.7
P value	0.108	0.161

Note: Data other than P values are the mean (standard deviation). For all groups, the stretch rate was 10 cm/min. In the study group, stimulation was applied with 12 mA at a frequency of 10 Hz.
