Identifying a Ranking Method for Assessing the Potential Risk of Knee Musculoskeletal Disorders among Roofers in Shingle Installation
The objective of this study is to identify a ranking method for assessing the potential risk of knee musculoskeletal disorders (MSD) among construction roofers. On a slope-adjustable wooden platform, nine subjects performed the shingle installation, comprising seven phases: 1) reaching for shingles, 2) placing shingles, 3) grasping the nail gun, 4) moving to the first nailing position, 5) nailing shingles, 6) replacing the nail gun, and 7) retuning to upright position. Knee flexion, abduction, adduction, internal, and external rotational angles were measured using an optical motion analysis system. To analyze the relative level of risk at each phase, these angles were combined using multiplication and aggregation-based scoring models that generated ranks of phases at different roof slopes. The ranking results provide useful information for identifying the postures that might pose greater MSD risk, and may facilitate effective interventions development to reduce extreme knee positions which is a MSD risk factor.
