Musculoskeletal Disorders' Classification Proposal for Application in Occupational Medicine

Area of Science:

• Occupational Medicine
• Clinical Pathology
• Orthopaedics

Background:

• Existing occupational classifications for musculoskeletal disorders (MSDs) are insufficient for clinical practice.
• Work-related MSDs (WRMSDs) share common pathophysiological development processes.
• A need exists for a unified classification system for WRMSDs.

Purpose of the Study:

• To develop and propose a novel, clinically applicable classification system for WRMSDs.
• To integrate aetiopathogenic, clinical, occupational, and radiological concepts into a single classification.
• To enhance the prevention and therapeutic management of WRMSDs.

Main Methods:

• Applied clinical pathology concepts to WRMSD pathophysiology, including cellular and tissue alterations.
• Correlated inflammatory mechanisms with injury onset, grading into four levels (MSDs 0-3).
• Incorporated criteria from legal, occupational, internal medicine, semiology, physiology, orthopaedics, and diagnostic imaging, validated by expert review.

Main Results:

• A four-level classification system for WRMSDs was developed, integrating diverse medical concepts.
• The classification facilitates improved determination of WRMSDs and guides preventive and therapeutic strategies.
• The tool enhances communication between occupational health physicians and other medical specialists.

Conclusions:

• The developed four-level classification provides a straightforward and understandable tool for WRMSDs.
• This classification aids in preventing injuries from becoming chronic and improves therapeutic management.
• Enhanced communication and a unified approach are facilitated for better WRMSD care.
