Table 1.

Group averages on each of four behavioral measures at each of four time points.

	ARAT (points)	9-HPT (seconds)	SIS ADL (score)	SIS HF (score)
Pre-therapy	27.78 (9.06)	52.59 (7.89)	68.06 (6.30)	26.11 (9.67)
Mid-therapy	26.44 (8.60)	52.10 (7.53)	72.22 (6.28)	30.56 (10.59)
Post-therapy	28.11 (9.03)	53.13 (6.70)	68.89 (5.59)	28.89 (10.30)
One month after BCI therapy	25.38 (10.09)	41.33 (7.00)	70.31 (6.02)	25.31 (10.74)

Numbers shown are group averages with standard error of the mean in parentheses. Scores for ARAT, SIS ADL, and SIS HF reflect data from all nine subjects. Scores for 9-HPT reflect values of only the four subjects who were able to complete the task within the allotted 5 min. ARAT = Action Research Arm Test, 9-HPT = Nine-Hole Peg Test, SIS ADL = Stroke Impact Scale—Activities of Daily Living, SIS HF = Stroke Impact Scale—Hand Function.
