Abstract
Objective
To assess differences in neural mechanosensitivity between patients with chronic nonspecific neck pain with and without neuropathic features (NF and No-NF, respectively).
Design
Descriptive, cross-sectional study.
Setting
A primary care center, a hospital physiotherapy outpatient department, and a university campus.
Subjects
Chronic nonspecific neck pain patients classified by the self-completed leeds assessment of neuropathic symptoms and signs pain scale (S-LANSS; 49 patients with NF [S-LANSS ≥ 12] and 50 patients with No-NF [S-LANSS < 12]) and a healthy control group (n = 48).
Methods
The primary measurements were the mechanosensitivity of the median nerve and cervical region, specifically the assessment of the onset of symptoms and submaximal pain intensity according to the upper limb neural test 1 (ULNT1) for the median nerve and the modified passive neck flexion test (MPNFT) for the cervical region; secondary measurements included pain intensity, neck disability, kinesiophobia, and pain catastrophizing.
Results
Statistically significant differences between the NF and No-NF groups were found with respect to the onset of symptoms of ULNT1 (−15.11 [−23.19 to −7.03]) and MPNFT (−6.58 [−11.54 to −1.62]), as well as the outcomes of the visual analogue scale (Mean difference [95% Confidence Interval]; 7.12 [1.81–12.42]) and neck disability index (3.72 [1.72–5.71]). Both chronic nonspecific neck pain groups showed statistically significant differences compared with the control group for all outcomes assessed (P < 0.01) except for the onset of symptoms of ULNT1 in the No-NF group.
Conclusions
The findings of this study suggest that chronic nonspecific neck pain patients with NF have greater neural mechanosensitivity, pain intensity, and neck disability than those with No-NF.
