Untangling function: measuring the severity, type and meaning of disabilities

Area of Science:

• Biomedical science
• Psychosocial science
• Rehabilitation medicine

Background:

• Current biomedical and psychosocial models are insufficient for understanding the illness-disability interface.
• A gap exists between objective biological measures and subjective patient experiences of function.

Purpose of the Study:

• To propose a novel framework for understanding illness and disability.
• To introduce the health environmental integration (HEI) model.
• To enhance the measurement of human function in rehabilitation.

Main Methods:

• Introduced the biopsycho-ecological model of health environmental integration (HEI).
• Proposed measuring function through severity of deficit, type of deficit, and meaning.
• Presented functional status staging and recovery preference exploration as measurement tools.

Main Results:

• The HEI model posits that functional abilities and their meaning arise from person-environment interactions.
• Measuring severity, type, and meaning of deficits is essential for a complete functional assessment.
• Functional status staging and recovery preference exploration offer methods to quantify these components.

Conclusions:

• The health environmental integration (HEI) model provides a more complete understanding of disability.
• Rehabilitation medicine can improve by incorporating the HEI framework.
• Measuring severity, type, and meaning of deficits is crucial for bridging biological and subjective aspects of function.
