Effect of Spinal Manipulative and Mobilization Therapies in Young Adults With Mild to Moderate Chronic Low Back Pain: A Randomized Clinical Trial.

Manual therapy is one of the most common treatments offered for chronic low back pain, and clinicians often debate whether forceful thrust techniques (spinal manipulation) work better than gentler nonthrust techniques (spinal mobilization). This trial compared both approaches against a placebo treatment, a sham cold laser, in young adults with mild to moderate chronic low back pain who received six sessions over three weeks. After treatment, there was no statistically significant difference in pain reduction or disability improvement between spinal manipulation and spinal mobilization, between spinal manipulation and placebo, or between spinal mobilization and placebo. In other words, neither manual therapy technique outperformed a sham treatment in this group.

The main limitation is that participants were relatively young with only mild to moderate pain, so the findings may not extend to older adults or those with more severe chronic low back pain.

If you've had chronic low back pain and wondered whether hands-on spinal treatments like manipulation (the kind involving a quick thrust) or mobilization (slower, gentler movement) actually help, this study offers a sobering answer. Researchers gave young adults with mild to moderate chronic back pain six sessions of one of these treatments, or a fake laser treatment used as a placebo, over three weeks. The result: none of the treatments stood out.

People who received spinal manipulation or spinal mobilization did not report significantly less pain or disability than those who received the placebo treatment. This doesn't mean these therapies never help anyone, but in this particular trial, involving a group of younger people with milder symptoms, neither approach showed a clear advantage over a sham treatment. Because the study focused specifically on young adults with mild to moderate pain, it's unclear whether the same result would hold for older adults or people with more severe or long-standing back pain.

This single-blinded, placebo-controlled randomized trial (n=162) compared spinal manipulation, spinal mobilization, and sham cold laser therapy across three groups of 54 in young adults (mean age 25 years) with mild to moderate chronic low back pain (baseline mean Numerical Pain Rating Scale score 4.3 out of 10). Six treatment sessions were delivered over three weeks, with coprimary outcomes of change in pain (NPRS) and disability (Roland-Morris Disability Questionnaire) assessed 48 to 72 hours post-treatment. No statistically significant between-group differences emerged for pain: manipulation versus mobilization (0.24; 95% CI, -0.38 to 0.86; P=.45), manipulation versus placebo (-0.03; 95% CI, -0.65 to 0.59; P=.92), or mobilization versus placebo (-0.26; 95% CI, -0.38 to 0.85; P=.39).

Disability findings followed the same pattern, with all confidence intervals crossing zero and no comparison reaching significance. The trial's investigator-blinded design and placebo control strengthen internal validity, but the young age and mild-to-moderate symptom severity of the sample limit generalizability to broader chronic low back pain populations, including older adults or those with more severe presentations. The abstract does not report adverse event data, so no safety conclusions can be drawn.
