The influence of physical and psychosocial variables on self-rated
disability in patients with chronic mechanical neck pain has not been fully
determined. This study examined the relationship of pain, physical impairment,
and pain-related fear to disability in individuals with chronic mechanical neck
pain. DESIGN: A cross-sectional study was conducted. Ninety-seven (n = 97)
subjects (28 men, 69 women; mean age, 39.3 yrs) with chronic mechanical neck pain
were prospectively recruited. Demographic information, duration of pain symptoms,
pain intensity, pain-related fear, and cervical range of motion were collected on
all subjects. Self-reported disability was measured with the Neck Disability
Index. Correlation and regression analyses were performed to determine the
association among the variables and to determine the proportions of explained
variance in disability. RESULTS: Significant positive correlations existed
between disability and previous history of neck pain (r = 0.45; P < 0.001),
disability and pain intensity (r = 0.32, P = 0.01), and disability and
kinesiophobia (r = 0.23, P = 0.02). In addition, a significant negative
correlation existed between disability and cervical extension range of motion (r
= -0.18, P = 0.04). Stepwise regression analyses revealed that previous neck pain
episodes, intensity of neck pain, kinesiophobia, and cervical extension range of
motion were significant predictors of disability
(r = 0.400; r adjusted = 0.372;
F = 14.64; P < 0.001). CONCLUSIONS: This study found that previous episodes of
neck pain, pain intensity,
pain-related fear, and cervical extension range of
motion explained 37.2% of the variability of self-report disability. Future
longitudinal studies will help to determine the clinical implications of these findings.
