Relationship between Fear-Avoidance Beliefs and Reaction Time Changes Prior to and following Exercise-Induced Muscle Fatigue in Chronic Low Back Pain

Table 2

Changes of TRT, PMT, and EMD before and after exercise-induced muscle fatigue (n = 25, s).

	Before MF	After MF	95% CI	Cohen’s d	η ^2	Z	value
TRT	0.358 (0.326, 0.415)	0.411 (0.353, 0.469)	0.026∼0.097	1.973	0.493	3.511	<0.001
PMT	0.333 (0.301, 0.390)	0.386 (0.328, 0.444)	0.024∼0.096	1.887	0.471	3.431	0.001
EMD	0.025 (0.025, 0.026)	0.025 (0.025, 0.027)	0.000∼0.003	0.421	0.042	1.029	0.304

Notes. . TRT: total reaction time; PRT: premotor time; EMD: electromechanical delay; η²: eta squared; MF: muscle fatigue.
