Development of a real‐time work‐related postural risk assessment system of farm workers using a sensor‐based artificial intelligence approach.

In recent years, the promotion of farm mechanization has been directed toward reducing the human discomfort and fatigue associated with various agricultural work‐related activities. During these activities, many factors (like force, awkward posture, vibration, repetition, etc.) play a significant role in causing musculoskeletal disorders. Second, ergonomic risk assessment of physical work is conventionally conducted through observation and direct/indirect physiological measurements. However, these methods are time‐consuming and require human subjects to perform the motion to obtain detailed body movement data. In the present study, a semiautomatic rapid entire body assessment (REBA) evaluation tool is developed for real‐time assessment of agricultural work‐related musculoskeletal disorders risk of farm workers using Kinect V2 sensor‐based artificial intelligence approach. It allows the investigator speedy detect of awkward postures leading to critical conditions and to reduce subjective bias. It is useful to analyze online as well as offline posture analysis, it detects the critical areas of the body posture, which may lead to the musculoskeletal disorders of agricultural workers, and suggest aptly to correct the posture. The Kinect V2 REBA assessment score was found with a factual significant match with the reference expert evaluation as reflected by the Landis and Koch scale k = 0.673 (p < 0.001), 95% confidence interval (CI) for the left side, and k = 0.644 (p < 0.001), 95% CI for the right side of the body respectively.
