Dual-channel	6	0.186 ± 0.076	0.333 ± 0.164^a	0.600 ± 0.1	0.590 ± 0.124	0.147 ± 0.091	−(0.009 ± 0.106)	0.069 ± 0.011	0.043 ± 0.021^a
Placebo	6	0.185 ± 0.12	0.217 ± 0.135	0.558 ± 0.123	0.562 ± 0.129	0.032 ± 0.052^bc	0.065 ± 0.118	0.061 ± 0.023	0.060 ± 0.025^bc

Value: mean ± SD; change value: FA values of week 3 minus those of week 0; rate of change value: (ipsilateral FA − contralateral FA)/ipsilateral FA^∗100%. ^ap < 0.05 indicates significant difference when compared with week 0 within groups. ^bp < 0.05 indicates significant difference when compared with the four-channel group. ^cp < 0.05 indicates significant difference when compared with the dual-channel group.
