• Conditions: Masonry Workers

• Registration Number: CTRI/2025/02/081300

Brief Summary

The study aims to investigate the connection between lower limb postural alignment, biomechanical characteristics, and functional performance in masonry workers. Given the physically demanding nature of masonry work—such as repetitive bending, lifting, and prolonged standing—these workers are at high risk for musculoskeletal disorders (MSDs). The research seeks to identify risk factors that contribute to postural imbalances and biomechanical inefficiencies, which can lead to long-term injuries and reduced functional performance. The study follows a correlational design with a sample size of 100 workers, aged 20-40 years, from residential construction sites in South Bangalore. Participants will be assessed for pain, disability, muscle strength, joint range of motion, and postural alignment using standardized tools like the Lower Extremity Functional Scale (LEFS), goniometer, inclinometer, and digital dynamometer. Various biomechanical factors, including limb length inequality, pelvic tilt, quadriceps angle, and tibiofemoral alignment, will be analyzed to understand their impact on mobility and work-related strain. The expected outcome of the research is to establish a significant relationship between postural deviations and functional limitations, thereby helping to develop ergonomic interventions that enhance worker safety and productivity.
