Two articles on PainSci cite Basson 2017: 1. Quite a Stretch 2. Neurodynamic Stretching
PainSci commentary on Basson 2017: ?This page is one of thousands in the PainScience.com bibliography. It is not a general article: it is focused on a single scientific paper, and it may provide only just enough context for the summary to make sense. Links to other papers and more general information are provided wherever possible.
The level of evidence for neural mobilization is “largely unknown” according to this review of forty studies (only seventeen with a low risk of bias, and with lots of variety in methods throughout). The results were mixed, and NM notably failed for relatively straightforward peripheral neuropathies like carpal tunnel syndrome — if NM is good for anything, it should be good for that, at least.
On the bright side, according to the paper, the data “reveals benefits of NM for back and neck pain,” but these are complex conditions and notoriously multifactorial, so I remain pessimistic in the absence of more and better data. As the authors understate: “Due to the limited evidence and varying methodological quality, conclusions may change over time.” I’d say it’s so likely that “conclusions may change” that the word “conclusion” isn’t really useful here.

STUDY DESIGN: Systematic review with meta-analysis.
BACKGROUND: Neural mobilization (NM) or neurodynamics is a movement-based intervention aimed at restoring the homeostasis in and around the nervous system. The current level of evidence for NM is largely unknown.
OBJECTIVES: To determine the efficacy of NM for musculoskeletal conditions with a neuropathic component.
METHODS: Databases were searched for randomised trials investigating the effect of NM for neuro-musculoskeletal conditions. Standard methods for article identification, selection and quality appraisal were used. Where possible, studies were pooled for meta-analysis. Primary outcomes were pain, disability and function.
RESULTS: Forty studies were included in this review, of which 17 had a low risk of bias. Meta-analyses could only be performed on self-reported outcomes. For chronic low back pain, disability (Oswestry (0-50): mean difference -9.26; 95%CI: -14.50 - -4.01; p=0.0001) and pain (Intensity (0-10): mean difference -1.78; 95%CI: -2.55 - -1.01; p=0.0001) improved following NM. For chronic neck-arm pain, pain improved (Intensity (0-10): mean difference -1.89; 95%CI: -3.14 - -0.64; p=0.0003) following NM. For carpal tunnel syndrome, NM was not effective for most clinical outcomes (p>0.11), but showed positive neurophysiological effects (e.g., reduced intraneural oedema). Due to a scarcity of studies or conflicting results, the effect of NM remains uncertain for various conditions, such as post-operative low back pain, cubital tunnel syndrome and lateral epicondylalgia.
CONCLUSION: This review reveals benefits of NM for back and neck pain, but the effect of NM for other conditions remains unclear. Due to the limited evidence and varying methodological quality, conclusions may change over time. Level of Evidence Level 1.
