N, number of cases included in each group; DN, dry needling; SDN, sham dry needling; CON, control.
§
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.
NA, Not Available.
