Rotation-traction manipulation versus cervical traction for axial neck pain caused by cervical degenerative disc disease: a multicenter randomized controlled trial.

Researchers in China compared two common treatments for neck pain caused by cervical degenerative disc disease: rotation-traction manipulation (a hands-on technique involving gentle twisting and pulling of the neck) and cervical traction (a mechanical pulling treatment applied daily). They enrolled 154 adults, randomly assigning them to one or the other treatment, and tracked their pain, neck tenderness, and neck movement over three months. Both treatments led to meaningful improvements in pain and movement by the end of the study.

When the researchers applied strict statistical controls, they found no clear winner between the two approaches. However, when they looked more loosely at the data, the hands-on manipulation appeared to work a bit faster during treatment and may have produced a slightly larger reduction in overall pain, though the difference was small. Neck tenderness improved faster in the manipulation group.

Neither treatment caused serious harm.

This study compared two ways of treating neck pain from wear and tear on the discs in your spine. One approach uses hands-on manipulation (gentle twisting and pulling movements), and the other uses a machine to pull your neck gently each day.

The good news is that both treatments helped people in this study improve their pain and movement over the course of three months. The study did not find a clear winner overall. Both approaches worked.

That said, the hands-on approach seemed to help people feel better a bit faster during the weeks of treatment, and it may have produced slightly more pain relief by the end, though the difference was not dramatic. The study was well-designed and included people from multiple clinics, which makes the findings more trustworthy.

The researchers also watched carefully for side effects and found that both treatments were safe, with only mild and minor problems reported.

This multicenter RCT offers a measured look at rotation-traction manipulation against cervical traction for mechanical neck pain in degenerative disc disease. The sample size was reasonable (n=154, with 151 completing follow-up), and the trial used intention-to-treat analysis with multiple imputation, which strengthens confidence in the results.

When the researchers applied confirmatory mixed-effects analyses with adjustment for multiple comparisons, the two groups showed no statistically significant difference in pain (VAS) or cervical range of motion, the primary and a key secondary outcome. Where the findings become more nuanced is in the exploratory analyses, which suggested faster pain reduction during the active treatment phase with RTM and a small cumulative pain advantage favoring manipulation. Neck tenderness severity also appeared to resolve more quickly in the RTM group, though the authors themselves note that the tenderness score lacks formal validation.

Adverse events were mild and infrequent in both groups, with no radiographic deterioration observed. The evidence here points toward comparable clinical utility rather than clear superiority of one method, with RTM showing potential advantages in the pace of early response rather than ultimate outcomes.
