§
>MAS, Modified Ashworth Scale, The Modified Ashworth Scale is a measure of spasticity (muscle tone) in the paralyzed arm; scores range from 0 to 4 at each joints, with higher scores indicating more severe spasticity.
γ
>Bonferroni correction was used for multiple comparisons between groups, α = 0.05/3 = 0.017.
※
> Statistically significant difference from DN group.
#
>No statistical significance as compared to SDN group; P-value of <0.05 was considered significant.
η
>Fisher's exact test.
