Area of Science:

• Rehabilitation Science
• Health Informatics
• Biomedical Engineering

Background:

• Low back pain (LBP) presents complex challenges due to its widespread prevalence and multifactorial nature.
• Prioritizing interventions based on functional impairments is essential for maximizing patient physical and psychological benefits.
• Graph modeling offers a promising approach to understanding these complex relationships.

Purpose of the Study:

• To construct a graphical model of functioning variables for LBP using the International Classification of Functioning, Disability, and Health (ICF).
• To identify key influential functioning variables impacting patients' physical and mental well-being.
• To explore potential intervention strategies by analyzing correlations in dysfunction among these variables.

Main Methods:

• A cross-sectional survey was conducted across nine hospitals in Jiangsu Province, China.
• 306 adult patients with LBP were assessed using the Comprehensive ICF Core Sets for LBP.
• Network parameters and Item Response Theory modeling were employed to determine item importance and estimate dysfunction correlations.

Main Results:

• The graphical model identified 56 ICF items in the LBP backbone structure.
• Lifting and carrying objects (d430) emerged as the most central item, followed by temperament and personality functions (b126).
• Significant dysfunction correlations were found between d430 and factors like health maintenance and joint stability, and between b126 and interpersonal interactions.

Conclusions:

• Lifting capacity (d430) and temperament (b126) are critical determinants of physical and mental well-being in LBP patients.
• Interventions should focus on improving exercise habits, managing work hours, enhancing lumbar stability, and addressing emotional factors for d430.
• Improving interpersonal relationships is key to enhancing b126, offering targeted pathways for LBP management.
