Mechanical hypersensitivity induced by L5 SNT. Ipsilateral (left) and contralateral (right) hind paw withdrawal thresholds (PWT) in response to electronic von Frey mechanical stimulation. Differences between and within groups were determined by two‐way repeated measure ANOVA. There were no differences in contralateral PWT, in contrast with ipsilateral data, which revealed a marked decrease in threshold in SNT animals 14 days after surgery. Mean and median are given to aid in data interpretation, highlighting variations in data distribution between groups and outcomes (n = 9).
