The aim of this study was to analyze the course of reduction of disability during
a pain rehabilitation program (PRP) and factors influencing this course. A
prospective cohort study was carried out. All patients with chronic
musculoskeletal pain treated in a PRP between March 2010 and December 2010 were
eligible for this study. All patients were treated at a University-based
rehabilitation center and received an outpatient multidisciplinary PRP. Main
outcome measures, Pain Disability Index (PDI), and average pain measured with a
numeric rating scale were measured every 2 weeks during the PRP. To analyze the
course of disability, a linear mixed-effect model was applied. One hundred and
twenty-eight patients participated in the study, of whom 20% dropped out during
the PRP. Initial PDI (beta=0.8), treatment week (beta=-0.2), treatment week
squared (beta=0.03), average pain (beta=2.3), and interaction between initial PDI
and treatment week (beta=-0.02) influenced the course of disability during PRP.
Disability reduces during the PRP. Initial PDI, treatment week, average pain, and
interaction between initial PDI and treatment week influence the course of
disability reduction during the PRP. These results could aid in predicting the
required duration of a PRP at the start.
