Effect of Core Stability Training Monitored by Rehabilitative Ultrasound Image and Surface Electromyogram in Local Core Muscles of Healthy People

Figure 2

Comparison of the effect on local core muscles between the monitoring group and control group in 0, 4, and 8 weeks. (a) Comparison of the muscle thickness activation ratio of TrA between the monitoring group and control group in 0, 4, and 8 weeks. Activation ratio = contraction thickness/relax thickness. (b) Comparison of the muscle thickness activation ratio of MF between the monitoring group and control group in 0, 4, and 8 weeks. Activation ratio = contraction thickness/relax thickness. (c) Comparison of the IEMG of TrA between the monitoring group and control group in 0, 4, and 8 weeks. (d) Comparison of the IEMG of MF between the monitoring group and control group in 0, 4, and 8 weeks Values are means ± s.e.m. values were calculated by the two-tailed Student’s t-test. value < 0.001; value < 0.01; value < 0.05.
