Effects of Joint Mobilization Versus Acupuncture on Pain and Functional Ability in People with Chronic Neck Pain: A Randomized Controlled Trial of Comparative Effectiveness.

Background: Chronic Neck Pain (CNP) is one of the main contributing factors to disability in people of working age.

Objectives: The aim of this randomized clinical trial was to compare the efficacy between acupuncture and joint mobilization on pain and disability in patients with CNP.

Methods: The study involved 45 men and women with CNP, divided into three groups of 15 each. The first group followed a manual therapy protocol with joint mobilization for eight weeks three times per week. The second group followed an acupuncture protocol of equal duration and frequency, while the third group did not follow any treatment. Pain with the Visual Analog Scale (VAS) for pain and functional limitations with the Neck Disability Index (NDI) questionnaire were assessed before and after an 8-week intervention. Analysis of variance was applied while post-hoc comparisons were made to determine the differences among the groups at each time of measurement.

Results: Both intervention groups showed statistically significant differences compared to the control group after the end of the intervention in both the VAS and the NDI scores (p< .001). Furthermore, the acupuncture group showed a statistically significant improvement compared to the joint mobilization team after the end of the intervention in the VAS score (p< .001) and the NDI score (p< .05).

Conclusion: Both joint mobilization and acupuncture appear to be effective interventions in reducing pain and improving functional ability in people with CNP. However, acupuncture appears to have a greater analgesic effect than joint mobilization.
