Does spinal manipulation (chiropractic care) help back pain?

Spinal manipulation eases back pain and improves function by modest amounts, about as well as recommended treatments. Serious harms are rare.

Published October 2026

Short answer

Spinal manipulation eases back pain and improves function by modest amounts, similar to recommended treatments, with rare but serious risks. Evidence grade B (Moderate). Several meta-analyses of randomised trials; downgraded for unexplained heterogeneity, small effects and author ties to chiropractic groups.

Key takeaways

Across 47 trials of chronic back pain, spinal manipulation gave pain relief similar to recommended treatments and a small improvement in function [1].
For acute back pain (up to 6 weeks), 15 trials found about 10 points of pain relief on a 100-point scale, compared with sham or other treatments [2].
Mild, short-lived side effects such as soreness, stiffness and headache were common; serious harms are rare, and most involved arteries in the neck [2][3].
The authors of the largest chronic back pain review include chiropractors who received grants from chiropractic associations [1].

The short version

Spinal manipulation can ease back pain and improve function, by modest amounts [1][2]. For chronic back pain it did about as well as recommended treatments [1]. Serious harms are rare but have been reported, mostly involving arteries in the neck [3].

What the studies show

The largest review is a 2019 BMJ meta-analysis of 47 trials with 9,211 people with chronic back pain. Spinal manipulation gave pain relief similar to recommended treatments, and pain relief was small and not clinically better than less effective options [1]. Function improved slightly more than with recommended treatments [1].

A 2018 review of 51 trials found manipulation and mobilisation reduced pain and disability more than other active treatments, and manipulation seemed to work better than mobilisation [4].

For acute back pain, a 2017 JAMA meta-analysis of 15 trials (1,711 people) found pain fell by about 10 points on a 100-point scale, compared with sham or other treatments, and function improved modestly across 12 trials [2].

The nuances

Results varied widely between trials, and the 2019 review could not explain why [1][2]. The evidence for sham manipulation was low to very low quality [1]. The 2019 review excluded trials that studied sciatica alone [1].

Mild side effects are common. In large case series, increased pain, muscle stiffness and headache were reported in 50% to 67% of patients [2]. In one study of 183 people, the risk of a side effect was not significantly higher than with sham manipulation [1]. Serious events were mostly arterial injuries linked to manipulation, but these come from case reports, so no rate can be estimated [3][5].

Some authors of the 2019 review work as chiropractors and received grants from chiropractic associations [1].

What this means for you

For back pain that has lasted a while, the trials suggest spinal manipulation is one reasonable option alongside recommended treatments [1]. Because most serious harms followed manipulation of the neck, talk to a doctor first, especially about neck pain [3].
