Do ICF core sets for low back pain include patients' self-reported activity limitations because of back problems?

Area of Science:

• Rehabilitation Medicine
• Health Services Research
• Disability Studies

Background:

• Low back pain (LBP) is a prevalent condition causing significant functional limitations.
• The International Classification of Functioning, Disability and Health (ICF) provides a standardized framework for describing health and disability.
• ICF Core Sets are designed to represent a minimum set of categories for specific health conditions.

Purpose of the Study:

• To evaluate the content validity of the ICF Core Sets for low back pain (LBP).
• To determine if commonly reported difficult activities by LBP patients are included in the ICF Core Sets.

Main Methods:

• A cross-sectional study involving 98 patients with chronic LBP (duration >3 months).
• Patients reported daily life and work task difficulties due to back pain.
• Responses were independently classified by two raters according to the ICF Core Sets' Activities and Participation component.

Main Results:

• The Comprehensive Core Set captured 52% of reported difficulties, while the Brief Core Set captured 75%.
• High inter-rater reliability was observed (Kappa values 0.80 and 0.9).
• Frequently reported limitations like sitting, standing, and walking were not specifically described in the Comprehensive Core Set.

Conclusions:

• The ICF Core Sets for LBP offer a broad overview of functional limitations but lack therapeutic specificity.
• The Comprehensive Core Set includes many reported activities but its categories are too general.
• The Brief Core Set omits important activity categories like pulling/pushing and leisure activities.
