	Subacute dTA (n = 16)	Subacute TA (n = 7)	Chronic dTA (n = 5)	Chronic TA (n = 5)	Control dTA (n = 23)
PE [%]	79 ± 14	98 ± 6	78 ± 16	100 ± 0	91 ± 9
DE [%]	37.9 ± 16.4	6.9 ± 1.8	29.4 ± 18.2	7.4 ± 3.4	39.4 ± 26.8
WTT [J]	1.39 ± 0.65	0.12 ± 0.38	1.87 ± 1.55	0.01 ± 0.17	1.23 ± 0.91
WAT [J]	0.02 ± 0.40	0.18 ± 0.28	0.19 ± 0.38	0.66 ± 0.83	0.03 ± 0.27

The results of placing efficiency (PE), deviation error (DE), work performed toward the target (WTT) and work performed away from the target (WAT). The subacute and chronic subjects are divided into the groups with tunnel assistance (TA) and without tunnel assistance (dTA). n is the number of subjects.
