Comparison of mean changes in FOIS after treatment

Values are presented as number (%).

In all periods, NMES/TDT group showed significant improvement compared to TDT group. NMES/TDT group showed improvement of FOIS in all periods. TDT group did not show significant improvement of FOIS in period of 6 weeks to 12 weeks later.

FOIS, Functional Oral Intake Scale; NMES/TDT group, patients treated by neuromuscular electrical stimulation combined with traditional dysphagia therapy; TDT group, patients treated by traditional dysphagia therapy only.

p<0.0083 (independent sample t-test) significant difference ^a)between baseline and 3 weeks later in each group, ^b)between baseline and 6 weeks later in each group, ^c)between baseline and 12 weeks later in each group, ^d)between 3 weeks and 6 weeks after stroke in each group, ^e)between 3 weeks and 12 weeks after stroke in each group, ^f)between 6 weeks and 12 weeks after stroke in each group.
