Abstract:
Objective:To investigate the prevalence and influencing factors of kinesiophobia in chronic pain patients undergoing conservative treatment for lumbar disc herniation (LDH), providing reference and basis for reducing the occurrence of kinesiophobia in this patient population.Methods:A cross-sectional study was conducted from May 2023 to January 2024. A convenience sample of chronic pain patients undergoing conservative treatment for LDH in Guangdong Second Provincial General Hospital was selected as the study population. Data were collected by the general information questionnaire, Numerical Rating Scale, Tampa Scale of Kinesiophobia-11, Psychological Inflexibility in Pain Scale, and Chronic Pain Self-efficacy Scale. A random forest model was constructed to rank variable importance, and binary Logistic regression was used to analyze the influencing factors of kinesiophobia.Results:The effective response rate of the questionnaire was 96.8% (270/279). Among 270 patients, there were 139 males and 131 females, 92 patients aged 18-40 years, 132 patients aged 41-60 years, and 46 patients aged >60 years old. The total kinesiophobia score for chronic pain patients undergoing conservative treatment for LDH was (31.00 ± 5.09) points, with a kinesiophobia prevalence of 79.6% (215/270). The random forest algorithm identified eight influencing factors: pain self-efficacy, psychological flexibility, physical exercise after low back pain onset, duration of pain, pain status, understanding of LDH, marital status, and pain intensity. Binary Logistic regression analysis showed that physical exercise after low back pain onset ( OR=0.583, 95% CI 0.344-0.986), pain status ( OR=0.424, 95% CI 0.206-0.873), psychological flexibility ( OR=1.102, 95% CI 1.052-1.155), pain self-efficacy ( OR=0.923, 95% CI 0.895-0.953) were significant influencing factors of kinesiophobia in chronic pain patients undergoing conservative treatment for LDH (all P<0.05). Conclusions:The prevalence of kinesiophobia is high among chronic pain patients undergoing conservative treatment for LDH. Physical exercise after low back pain onset, pain status, psychological flexibility, and pain self-efficacy are significant influencing factors. Healthcare professionals should pay increased attention to kinesiophobia in chronic pain patients undergoing conservative treatment for LDH and implement targeted early interventions to reduce its occurrence.
