Table 2. P-value and effect size for the sEMG comparison between the tested and the not tested side for the original and standardized version of the Bunkie Test.

muscle	original test version	standardized test version
M. erector spinae	0.96 (r = 0.23)	0.21 (r = 0.43)
M. gluteus maximus	0.08 (r = 0.27)	0.12 (r = 0.25)
M. biceps femoris	0.08 (r = 0.43)	0.004* (r = 0.54)
M. gastrocnemius	0.92 (r = 0.01)	0.99 (r = 0.08)

sEMG, surface electromyography. The effect size r is classified as 0.10 ≤ 0.30 = small, 0.30 ≤ 0.50 = moderate, ≥ 0.50 large;* indicates a statistically significant difference p < 0.05.
