DN, dry needling; SDN, sham dry needling; CON, control; MCP, metacarpophalangeal joint; IP, interphalangeal joint; DIP, distal interphalangeal joint; PIP, proximal interphalangeal joint.
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.
