RESUMO

The aim of this study was to determine the muscle load reduction of the upper extremities and lower extremities associated with wearing an exoskeleton, based on analyses of muscle activity (electromyography: EMG) and the AnyBody Modeling System (AMS). Twenty healthy males in their twenties participated in this study, performing bolting tasks at two working heights (60 and 85 cm). The muscle activities of the upper trapezius (UT), middle deltoid (MD), triceps brachii (TB), biceps brachii (BB), erector spinae (ES), biceps femoris (BF), rectus femoris (RF), and tibialis anterior (TA) were measured by EMG and estimated by AMS, respectively. When working at the 60 cm height with the exoskeleton, the lower extremity muscle (BF, RF, TA) activities of EMG and AMS decreased. When working at the 85 cm height, the lower extremity muscle activity of EMG decreased except for TA, and those of AMS decreased except for RF. The muscle activities analyzed by the two methods showed similar patterns, in that wearing the exoskeleton reduced loads of the lower extremity muscles. Therefore, wearing an exoskeleton can be recommended to prevent an injury. As the results of the two methods show a similar tendency, the AMS can be used.

RESUMO

Farming is a strenuous occupation with various health risks, with musculoskeletal disorders (MSDs) being some of the most common. The risk factors for MSDs among Korean farmers are not well understood. Data were obtained from the Korean Farmers' Occupational Disease and Injury Survey (2012), which interviewed 16,113 participants regarding their demographic profiles, self-reported MSDs, and agricultural characteristics. Multiple logistic regression analysis was used to identify the risk factors for MSDs. Subjects reported MSDs in the neck or upper extremities (5.89%), lower extremities (19.62%), and back (26.9%). Working in animal husbandry significantly increased the risk of MSDs in the neck/upper extremities, compared with irrigation farming (odds ratio: 1.837, 95% confidence interval: 1.130-2.987). The risk of MSDs increased significantly with number of years of farming, after adjusting for age and sex (neck/upper extremities, P for trend = .0002; lower extremities, <.001; back, <.001). Agriculture type, years of farming, and ergonomic factors increased the risk of MSDs among Korean farmers.
