Efficacy of Spine High-Velocity Low-Amplitude Thrust Manipulations in Patients With Radiculopathy: A Systematic Review With Meta-Analysis.

Researchers looked at whether high-velocity low-amplitude thrust manipulations, the kind of manual therapy technique that creates a quick, forceful movement through a joint, could help people with nerve pain radiating down the arm or leg from problems in the cervical, thoracic, or lumbar spine. They pooled results from eleven randomized controlled trials involving nearly a thousand patients and compared thrust manipulation to sham manipulation, standard physical therapy, and other techniques. The technique appeared to reduce pain more than fake manipulation and better than physical therapy alone over the short and medium term, roughly 2 to 12 weeks.

However, the benefits disappeared by long-term follow-up, and the overall quality of the evidence was mixed, ranging from very low to moderate certainty.

This study looked at whether a specific manual therapy technique, sometimes called a spinal adjustment or manipulation, could help people living with radiculopathy, the sharp or burning pain that travels down your arm or leg when a nerve in your spine is irritated. Across eleven different studies, people who received this type of manipulation reported somewhat less pain than those who received a fake version or physical therapy alone, but only in the short run, roughly a few weeks to a few months.

Once researchers followed people longer, those differences faded away, which suggests the relief may be temporary rather than lasting. The evidence was mixed in quality, so while the studies did show some benefit early on, we cannot yet say how reliable this finding is or whether it holds true for everyone.

This meta-analysis adds a layer of nuance to manual therapy for radiculopathy. High-velocity low-amplitude thrust techniques showed small but measurable pain reductions compared to sham and to physical therapy alone over short and medium timeframes, with effect sizes around one point on a pain scale.

The catch is that the certainty of evidence ranged from very low to moderate, and the benefits did not persist at longer follow-up. The comparison to spinal mobilization with leg movement is particularly telling: thrust manipulation showed no advantage over that approach, suggesting that the active ingredient may not be the forceful nature of the thrust itself but rather the movement and patient engagement.

The high overall risk of bias in included trials and the heterogeneity in study designs mean these findings are useful directional signals but not yet firm ground for clinical decision-making. More rigorously designed trials with consistent long-term follow-up would clarify whether short-term pain reduction translates to meaningful functional recovery.
