Ergonomic Risks and Musculoskeletal Disorders in Construction and Maintenance Work: A Case Study of Eddie’s Journey

This study examines the long-term musculoskeletal effects experienced by Eddie, a 71-year-old retired construction worker and building superintendent. Over several decades, Eddie’s work involved repetitive lifting, bending, twisting, and heavy tool use, factors contributing to chronic pain in his knees, back, shoulders, and wrists. Two ergonomic analysis tools were applied: the Rapid Entire Body Assessment (REBA) and the Hand Activity Threshold Limit Value (TLV). The REBA identified shoveling tasks as high-risk (score = 9), with excessive trunk flexion and repetitive motion driving strain. The Hand TLV showed Eddie’s right hand exceeded the threshold limit, indicating high ergonomic risk from repetitive, forceful tool use. Findings align with diagnoses of osteoarthritis, carpal tunnel syndrome, and degenerative disc disease. Psychosocial stressors, heavy workloads, limited job control, and irregular hours further worsened his condition. Recommended interventions include ergonomic tool modifications (e.g., Reach Right shovel handles), the use of cooling and back-support braces, and structured physical recovery programs to reduce the risk of future injuries. Overall, the study emphasizes the significance of ergonomic design and preventive measures in labor-intensive work to maintain long-term mobility and health.
