Work retention and nonspecific low back pain

Area of Science:

• Rehabilitation Medicine
• Occupational Health
• Psychosomatic Medicine

Background:

• Nonspecific low back pain (LBP) significantly impacts work retention.
• Limited research exists on factors predicting long-term work retention after LBP treatment.
• Exploratory study to identify physical and psychosocial predictors of work retention.

Purpose of the Study:

• To identify factors predicting work retention 24 months post-treatment in patients with nonspecific LBP.
• To explore the association between baseline physical and psychosocial factors and sustained work retention.

Main Methods:

• Cohort study of 67 patients with nonspecific LBP undergoing a 4-week multidisciplinary rehabilitation program.
• Baseline physical (flexibility, strength, functional capacity) and psychosocial (Symptom Checklist 90-R, Pain Beliefs, Oswestry Scale, Work Stress, Quality of Life) measures were collected.
• Work retention (days worked over 2 years) was the dependent variable; survival analysis was used for prediction modeling.

Main Results:

• Post-treatment trunk flexion, somatization scores, and obsessive-compulsive scores significantly predicted work retention.
• Improved trunk flexion (HR=2.5) and lower somatization (HR=2.5) and obsessive-compulsive (HR=0.2) symptoms were associated with better work retention.
• 25% of participants experienced work retention interruption during the 2-year follow-up.

Conclusions:

• Both physical (trunk flexion) and psychosocial (somatization, obsessive-compulsiveness) factors are associated with work retention in nonspecific LBP patients.
• The predictive value of these factors may depend on assessment timing and outcome operationalization.
• Further research is needed to validate these findings and refine predictive models for work retention.
