The Effect of Monochromatic Infrared Photo Energy on the Irritability of Myofascial Trigger Spot of Rabbit Skeletal Muscle

Table 1

Comparison of EPN prevalence between experimental and control sides (between-group comparison) and among 3 conditions in each side (within-group comparison: before, immediately after, and one week after MIRE application).

	Before; MIRE	Immediate after MIRE		One week after MIRE		p value
	Pre (%)	Im (%)	(%)	1 wk (%)	(%)	Pre versus Im	Pre versus 1 wk	Im versus 1 wk
Experimental side; ()	21.61 ± 4.75	11.33 ± 2.84	46.14 ± 12.81	16.15 ± 5.59	−52.29 ± 71.96	0.0005	0.0107	0.0029
Control side; ()	16.41 ± 4.39	14.19 ± 4.02	11.48 ± 18.60	16.93 ± 2.39	−28.05 ± 41.01	0.2891	0.0547	0.4063

EPN: endplate noise; MIRE: monochromatic infrared photo energy; Pre: % EPN prevalence before MIRE; Im: % EPN prevalence immediately after MIRE; 1 wk: % EPN prevalence one week after MIRE; : % difference between values before MIRE and values immediately after MIRE; : % difference between values before MIRE and values one week after MIRE. Values are mean ± SD or value.
Wilcoxon signed rank test of variance was used to compare the values before MIRE, values immediately after MIRE, and values one week after MIRE.
Wilcoxon signed rank test was used to compare the values between the experimental side and the control side.
