Recovery of the 20 Hz Rebound to Tactile and Proprioceptive Stimulation after Stroke

Table 3

Mean strengths (±SEM) of the 20 Hz rebounds in the patients and the controls.

	Patients			Patients			Controls
	AH-impaired			UH-healthy			Contra H
Time	T0	T1	T2	T0	T1	T2
Rebound to tactile stimulation	22 ± 6.1	41 ± 6.7	50 ± 7.7	47 ± 4.4	66 ± 9.6	73 + 1.1	57 ± 4.9
Rebound to passive movement	24 ± 4.3	39 ± 6.0	44 ± 5.0	48 ± 4.4	59 ± 6.6	65 ± S.5	97 ± 9.3

AH-impaired: affected hemisphere, impaired hand stimulation; UH-healthy: unaffected hemisphere, healthy hand stimulation; T₀: 1–7 days; T₁:1 month; T₂:12 months from stroke; Contra H: hemisphere contralateral to the stimulation. In the controls, contralateral responses in the left and right hemispheres are pooled.
