1 · What the graph read from it

What it found

Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.

The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.

2 · The registry

The trial behind it

Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.

Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract

Physical fatigue significantly contributes to work-related musculoskeletal disorders, highlighting the need to understand its effects during manual handling tasks for effective prevention strategies. This study examines the correlation between changes in the myoelectric manifestation of fatigue (MMF) indicators and participants' perceived exertion during prolonged manual handling tasks using surface electromyography (sEMG) sensors. Given that the task involves various activities with different muscle engagements and ranges of motion, joint angles were obtained using inertial measurement units and used to segment the sEMG recordings based on activity and the joints' range of motion. Linear and complexity-based MMF indicators were then extracted from these segments, and their correlation with perceived exertion was evaluated. Linear indicators, such as activation level and median frequency, showed significant correlations with perceived fatigue (p < 0.05) in the lower leg muscles, including Lateral Gastrocnemius and Tibialis Anterior, with inconsistent results in other muscles. In contrast, complexity-based indicators, including mobility, fuzzy entropy, and Dimitrov's index, demonstrated significant correlations (p < 0.05) in eight out of ten studied muscles across all activities, revealing reduced signal variability, increased irregularity, and shifts in spectral properties as fatigue progressed. Finally, a deep learning model was developed, achieving 69% accuracy for a five-stage fatigue classification using MMF indicators. Our study showed that complexity-based MMF indicators outperform linear ones in monitoring perceived fatigue and that the full set of indicators can be used for classifying fatigue stages using machine learning, offering a practical approach for personalized fatigue and health monitoring in occupational settings.
