Intrahemispheric and cerebral theta to beta ratio (TBR) in poststroke patients with upper limb mild/moderate and severe motor impairment and healthy subjects.

	Intrahemispheric index		Cerebral index	Within-group differences
	Affected/non-domH	Unaffected/domH		Affected/non-domH vs. unaffected/domH	Affected/non-domH vs. cerebral index	Affected/domH vs. cerebral index
Healthy	2.08 ± 0.70	2.11 ± 0.67	2.09 ± 0.71	—	—	—
Poststroke patients	5.39 ± 2.44	4.85 ± 2.09	5.07 ± 2.18	t = −2.38; p = 0.02	t = 2.51; p = 0.01	t = −2.04; p = 0.04
Mild/moderate	4.67 ± 1.90	4.49 ± 1.78	4.54 ± 1.74	—	—	—
Severe	6.21 ± 2.7	5.27 ± 2.37	5.66 ± 2.49	t = −2.35; p = 0.02	t = 2.33; p = 0.03	t = −2.17; p = 0.04

non-domH: nondominant hemisphere; domH: dominant hemisphere. Data are mean ± SD. Significant post hoc test values for within-group differences are shown.
