Evaluation of Postural Balance and Articular Mobility of the Lower Limbs in Chronic Neck Pain Patients by Means of Low-Cost Clinical Tests.

OBJECTIVE

The purpose of this study was to correlate measurements of chronic neck pain with the balance and mobility of the lower limbs and to compare these variables between individuals with chronic neck pain and asymptomatic participants.

METHODS

This was a blinded cross-sectional study. Participants with chronic neck pain (n = 30) and asymptomatic participants (n = 30) were included in the study. To measure pain in the neck region, the Numeric Rating Scale, Neck Disability Index, and Pain-Related Catastrophizing Thoughts Scale were applied. The assessment of postural balance and mobility of the lower limbs was made using the Timed Up and Go Test, Functional Reach Test (FRT), Lateral Reach Test, and 30-second Chair Stand Test.

RESULTS

No statistically (P > .05) and clinically (d < 0.50) significant differences were identified for the variables tested here. However, regarding the correlations, a significant association was identified only between the intensity of pain during cervical movements and FRT (r = -0.312).

CONCLUSION

Young adults with chronic neck pain present changes in static balance measured by means of the FRT; that is, the higher the intensity of pain, the lower the anteroposterior excursion of the body during the execution of the test.
