Effects of spinal manipulation or mobilization as an adjunct to neurodynamic mobilization for lumbar disc herniation with radiculopathy: a randomized clinical trial.
Featured on Physle Daily · Monday, 24 August 2026
When a lumbar disc herniation irritates a nerve root, causing radiating leg pain known as radiculopathy, physiotherapists have several manual therapy options to combine with nerve gliding exercises. This trial compared two of them, spinal manipulation and a mobilization technique called Mulligan's mobilization with movement, both given alongside neurodynamic mobilization, in people with chronic disc-related radiculopathy lasting three months or more. Over twelve weeks of twice-weekly treatment, and followed for a full year, the mobilization group showed consistently better improvements than the manipulation group across pain, activity limitation, sciatica symptoms, mobility, and quality of life, with differences reaching statistical significance at nearly every time point checked.
The abstract also describes several of these improvements as clinically meaningful, particularly for activity limitation, mobility, and quality of life at all follow-up points. This is a notably consistent pattern favoring one manual technique over another, but the trial included only forty participants split across two groups, which limits how confidently these results can be generalized to broader practice.
If you've been dealing with leg pain from a slipped or bulging disc in your lower back, you may know that physiotherapists have different hands-on techniques to try alongside nerve-stretching exercises. This study looked at forty people with this kind of long-term nerve pain and compared two approaches, a firmer spinal manipulation technique and a gentler mobilization technique performed while moving the leg, both paired with nerve gliding exercises.
People who received the mobilization technique reported better improvements in pain, daily activity, walking ability, and quality of life than those who received manipulation, and this pattern held up consistently over a full year of follow-up. This is an encouraging pattern from the paper, but it comes from a small trial of only forty people, so it's not yet strong enough evidence to draw firm conclusions about which approach works best for everyone with this condition. Larger studies would help confirm whether these differences hold up more broadly.

This single-blind randomized clinical trial compared spinal manipulative therapy and Mulligan's mobilization with leg movement, each combined with neurodynamic mobilization, in forty participants with chronic disc herniation with radiculopathy of at least three months' duration, allocated twenty per group. Outcomes were assessed at baseline, six, twelve, twenty-six, and fifty-two weeks, with pain and activity limitation at twelve weeks as primary outcomes. The mobilization group demonstrated statistically significant between-group superiority over the manipulation group across essentially all outcomes and time points, with exceptions limited to sensory deficit at fifty-two weeks and reflex and motor deficits at twelve and fifty-two weeks.
The abstract specifies clinically meaningful differences for neurodynamic testing and sensory deficits at twelve weeks, back pain intensity at six weeks, and activity limitation, functional mobility, and quality of life across all follow-up points. Relative risk for improvement at twelve weeks was 0.6 (confidence interval 0.4 to 0.9, p equals 0.007) favoring the mobilization group, indicating a forty percent lower likelihood of improvement in the manipulation arm. Given the small sample size and single-center design, these findings should be interpreted as preliminary evidence of a between-group difference rather than a definitive practice-changing result, and replication in larger, adequately powered trials would strengthen confidence in the magnitude and durability of this effect.
In this small trial of forty participants, Mulligan's mobilization with leg movement plus neurodynamic mobilization produced statistically significantly better outcomes than spinal manipulation plus neurodynamic mobilization across nearly all measures and follow-up points up to one year.
The risk of improvement at twelve weeks was forty percent lower in the manipulation group compared to the mobilization group, based on a relative risk of 0.6 with a confidence interval of 0.4 to 0.9.
The trial's small sample size of only twenty participants per group limits confidence in how broadly these findings on manual therapy choice for disc-related radiculopathy can be generalized.
