WMFT Time (s)	D0	42.5 ± 39.8	−22.6 ± 28.8
WMFT Time (s)	D14	18.4 ± 28.4	−22.6 ± 28.8
WMFT Function	D0	2.4 ± 1.1	1.2 ± 0.8

Participation measures
MAL How well	D0	0.5 ± 0.5	1.2 ± 0.9
MAL How well	D14	1.7 ± 1.1	1.2 ± 0.9
Duration of use (hours)	D0	3.3 ± 1.8	1.2 ± 1.4
Duration of use (hours)	D14	4.4 ± 2.1	1.2 ± 1.4

SD: standard deviation; ARAT: Action Research Arm Test; WMFT: Wolf Motor Function Test; MAL: Motor Activity Log; D0: study day 0, an average of 9.5 days post stroke; D14: study day 14, an average of 25.9 days post stroke.

Note that improvement on the WMFT Time score is indicated by a negative number, i.e. shorter time to complete test items. For all other measures, improvement is indicated by a positive number.
