The Relationship between Ischemic Stroke Patients with and without Retroflex Tongue: A Retrospective Study

Table 2

The severity assessment of ischemic stroke patients between retroflex tongue and nonretroflex tongue groups.

Variable	Retroflex tongue		value
	With	Without
Length of stay (day), mean (SD)	25.9 (14.4)	32.0 (21.5)
NIHSS score, mean (SD)	8.9 (5.2)	14.1 (7.8)	<0.001
Barthel Index, mean (SD)	35.0 (24.2)	18.6 (20.7)	<0.001

Student’s t-test and Chi-square test or Fisher’s exact test; has significant statistical differences.
National Institutes of Health Stroke Scale (NIHSS) ranges from 0 to 42 scores; the higher the score means higher neurodamage. The NIHSS has a total of 15 items.
Barthel Index is a common life function scale, ranging from 0 to 100 scores. The lower the score, the higher the life-dependency. Barthel Index has five degrees; scores of 0–20 indicate “total” dependency, 21–60 “severe” dependency, 61–90 “moderate” dependency, 91–99 “slight” dependency, and 100 “total” independency. The cases collected mostly belong to severe dependency.
