VAS: Visual Analogue Scale; NDI: Neck Disability Index; Flex: Flexion, deg.: degrees; Ext: Extension; RR: Right Rotation; LR: Left Rotation; RLF: Right Lateral Flexion; LLF: Left Lateral Flexion; CI: Confidence interval; p: probability value. *Data are mean± SD, P-Value < 0.05 indicate statistical significance.
