Table 2.

Average change observed during pre-therapy and BCI therapy periods for each of four subjects with additional behavioral assessments prior to the start of BCI therapy.

	ARAT (points)		9-HPT (seconds)		SIS-ADL (score)		SIS-HF (score)
Subject	Pre-Therapy	BCI Therapy	Pre-Therapy	BCI Therapy	Pre-Therapy	BCI Therapy	Pre-Therapy	BCI Therapy
A	Floor	Floor	Unable	Unable	−11.67	5	1.67	−5
B	−0.33	2.5	−33.51	−3.49	−2.5	3.75	−1.67	0

D	2	−4.33	−26.11	17.52	−2.5	−21.67	18.33	−21.67

Floor = a floor effect was observed in which the subject was unable to score points for the measure at any time point assessed. Unable = subject was unable to perform the task within the allotted 5 min time period. 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.
