Effects of trunk training using motor imagery on trunk control ability and balance function in patients with stroke

Table 4 Comparison of RMS values of the bilateral rectus abdominis and erector spinae (µV, \(\bar x \pm s\))before and after four weeks of treatment

	Affected side of control group		Healthy side of control group		Affected side of trial group		Healthy side of trial group
	Rectus abdominis	Erector spinae	Rectus abdominis	Erector spinae	Rectus abdominis	Erector spinae	Rectus abdominis	Erector spinae
Before treatment	12.13 ± 5.58	13.56 ± 5.68	22.52 ± 7.56	24.93 ± 6.68	12.37 ± 6.63	13.25 ± 5.34	23.73 ± 8.01	25.82 ± 6.88
After treatment	16.46 ± 5.67	16.82 ± 5.26	21.73 ± 6.48	23.15 ± 6.25	20.76 ± 5.23	21.82 ± 5.34	21.24 ± 7.34	22.85 ± 6.23

Note: Before treatment, the comparison of the bilateral rectus abdominis and erector spinae between the two groups showed P > 0.05. After four weeks of treatment, the bilateral rectus abdominis and erector spinae of the trial group were compared with those before treatment (P < 0.05). The rectus abdominis and erector spinae on the affected side of the control group were compared with those before treatment (P < 0.05), while the rectus abdominis and erector spinae on the healthy side of the control group were compared with those before treatment (P > 0.05). After four weeks of treatment, the rectus abdominis and erector spinae on the affected side of the trial group were compared with those of the control group (P < 0.05). The rectus abdominis and erector spinae on the healthy side of the trial group were compared with those of the control group (P > 0.05)
