Ergonomic Assessment of a Lower-Limb Exoskeleton through Electromyography and Anybody Modeling System.

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.

Musculoskeletal Disorders and Agricultural Risk Factors Among Korean Farmers.

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.
