ABSTRACT
BACKGROUND AND OBJECTIVES:
Chronic non-specific low back pain is a disabling condition that has a high worldwide prevalence. The aim of the study was to investigate the association between deficits in dynamic balance, age and body mass index (BMI), and kinesiophobia, as well as to establish a comparison between men and women.
METHODS:
A cross-sectional study with 145 individuals between 18 and 50 years of age with non-specific chronic low back pain. Sociodemographic data were collected, and dynamic balance was assessed using the Y-Balance Test. The Tampa Scale was used to assess kinesiophobia. A linear regression was applied to investigate the association between kinesiophobia and a set of predictor variables (balance, gender, BMI). Men and women were compared using the Student’s t-test (kinesiophobia and dynamic balance).
RESULTS:
The overall mean kinesiophobia score was 41.3. The Y-Balance Test mean for the right and left lower limb, respectively, was 59.4 and 59.5. An association was found between kinesiophobia and two predictors: balance and BMI (R2:6.8%). No significant differences were found between gender for kinesiophobia (42.1 for women and 40.3 for men). However, women had worse dynamic balance compared to men (mean reach of 56.1 versus 63.5, respectively; p<0.05).
CONCLUSION:
Kinesiophobia was found to be associated with disturbances in dynamic balance and BMI of individuals with non-specific chronic low back pain. However, the model explained a small variation in kinesiophobia. Women showed worse dynamic balance compared to with men.
