Background
Neck pain remains a persistent challenge in modern society and is frequently encountered across a wide range of occupations, particularly those involving repetitive and monotonous tasks. It might be expected that patterns of trapezius muscle activity at work, characterized by few breaks and prolonged periods of sustained muscle activity,...
OBJECTIVES: Both high and low levels of occupational physical activity are associated with back pain. Thus, there might be a “sweet- and sour-spot” of occupational physical activity for back pain. Our aim was to investigate if there exists an occupational physical activity “sweet- (lowest risk) and sour-spot” (highest risk) for back pain.
METHODS:...
Purpose
Longitudinal studies across various sectors with physically demanding jobs are notably absent in back disorder risk research. This study aimed to investigate the relationship between cumulative physical job exposure (PJE) and hospital-diagnosed back disorders among individuals in Denmark. To assess the healthy worker effect, we compared the...
