Objectives:
To develop a framework for evaluating the work related musculoskeletal disorders (WRMSDs).
Participants:
The proposed framework was tested on 15~jewellery manufacturing workers working at Chinchpokhli region in Mumbai, India and on 15 students studying in a management institute of Mumbai, India.
Methods:
The framework has been broken into three phases. Phase 1--Ergonomic-risk evaluation; Phase 2--Musculoskeletal Disorders (MSD) evaluation and Phase 3--Clinical examination. Ergonomic-risk evaluation determines the relationship between work relatedness and musculoskeletal disorders. Musculoskeletal Disorders (MSD) evaluation tries to assess the presence of discomforts/disabilities in different body regions, through subjective evaluation tools. Ergonomic-risk evaluation involved QEC, PLIBEL and posture analysis by RULA. Musculoskeletal Disorders (MSD) evaluation involved administration of self reported questionnaires. Clinical examination involved muscle grading by a physiotherapist and back strength measurement.
Results:
The framework suggested that ergonomic risk evaluation techniques, self reported body part questionnaires and physical measurement of physiological/biomechanical transients may have a relationship and can be used for the evaluation of work related musculoskeletal disorders.
Conclusion:
The proposed integrative approach will help in developing stage wise intervention strategies for work related musculoskeletal disorders.
