Results of clinical efficacy of functional scores. A Changes in A-VAS scores over time. B Changes in N-VAS scores over time. C Changes in JOA scores over time. D Changes in NDI scores over time. A-VAS, Arm Visual Analog Scale; N-VAS, Neck Visual Analog Scale; JOA, Japanese Orthopedic Association; NDI, Neck Disability Index. a-f indicate the letter labelling of the time point difference (comparison within the group), if 2 time points have the same letter, there is no significant difference between the 2 time points (P > 0.05); otherwise, different letters at 2-time points mean the difference is significant (P ≤ 0.05). Δ represents a significant difference between the two groups
