“…13 Moreover, the muscle force estimation was relied on the static optimization algorithm, while the recorded muscle activation data through surface EMG were not accounted, thus the Computed Muscle Control (CMC) method should be considered in the future. 61 The AT material property was taken from the previous study, and the foot-ankle complex geometry was obtained in an unloaded position from the MRI scanning. Thus, the finite element model sensitivity should be performed in future studies.…”

Achilles tendon rupture (ATR) incidence has increased among badminton players in recent years. The foot internal stress was hard to obtain through experimental testing. The purpose of the current research is to develop a methodology that could improve the finite element model derived foot internal stress prediction for ATR clinical and rehabilitation applications. A subject-specific musculoskeletal model was combined with a 3D finite element model to predict the metatarsal stress. The 80% point during the push-off phase of walking was selected for the comparing between injured and uninjured sides. The surgical repaired Achilles tendon (AT) after 12 months was elongated by 5.5% than the uninjured tendon. At 80% point of stance phase, the ankle plantarflexion angle and AT force decreased by 39.6% and 21.9% on the injured side, respectively. The foot inversion degree increased by 22.9% and was accompanied by the redistribution of metatarsals von Mises stress. The stresses on the fourth and fifth metatarsals were increased by 59.5% and 85.9% on the injured side. The workflow is available to assess musculoskeletal disorders and obtain foot internal stress after ATR. The decreased ankle plantar flexor force may be affected by triceps surae muscle atrophy and weakened force transmission ability of elongated AT. The increased von Mises stress on fourth and fifth metatarsals accompanied by higher foot inversion may increase the ankle lateral sprain injury risk.

“…There are some limitations to this study. The muscle architectural parameters of the musculoskeletal model, such as the force-length relationship of muscle and tendon, may not represent the muscle architectural parameters of the real harvesters [26,35,46]. Moreover, the assumption that the harvesting force was 303.5N may not represent the actual harvesting force for each harvester.…”

This study aims to create and evaluate an upper extremity musculoskeletal model of the oil palm harvesting motion and assess the Musculoskeletal Disorder (MSD) risk of this activity. Tests were conducted on six harvesters at a Malaysia oil palm plantation. Six Inertial Measurement Units (IMU) and Surface Electromyography (sEMG) were used to collect kinematics of the back, shoulder and elbow joints and measure the muscle activations of longissimus, multifidus, biceps and triceps. A musculoskeletal model was constructed and simulated using the IMU data. The results were benchmarked against the commercial motion capture tool and sEMG. It was found that joint angle had the maximum coefficient of correlation (R) of 0.99 and minimum Root Mean Square Error of 1.84°, whereas muscle activation had the maximum R of 0.87 and minimum Mean Absolute Error of 0.10. This study showed that the longissimus was more actively used than multifidus, and the biceps was another primary muscle relied on during harvesting. The harvesters faced a higher risk of MSD while performing back flexion, back rotation, shoulder flexion and elbow flexion. Lastly, it demonstrated the feasibility of the musculoskeletal modelling and simulation to further investigate the upper extremity joints and muscles during harvesting.

Oil palm harvesting is a labor-intensive activity and yet it was rarely investigated. Studies showed that complementing human motion analysis with musculoskeletal modelling and simulation can provide valuable information about the dynamics of the joints and muscles. Therefore, this study aims to be the first to create and evaluate an upper extremity musculoskeletal model of the oil palm harvesting motion and to assess the associated Musculoskeletal Disorder (MSD) risk. Tests were conducted at a Malaysia oil palm plantation. Six Inertial Measurement Units (IMU) and Surface Electromyography (sEMG) were used to collect kinematics of the back, shoulder and elbow joints and to measure the muscle activations of longissimus, multifidus, biceps and triceps. The simulated joint angles and muscle activations were validated against the commercial motion capture tool and sEMG, respectively. The muscle forces, joint moments and activations of rectus abdominis, iliocostalis, external oblique, internal oblique and latissimus dorsi were investigated. Findings showed that the longissimus, iliocostalis and rectus abdominis were the primary muscles relied on during harvesting. The harvesters were exposed to a higher risk of MSD while performing back flexion and back rotation. These findings provide insights into the dynamical behavior of the upper extremity muscles and joints that can potentially be used to derive ways to improve the ergonomics of oil palm harvesting, minimize the MSD risk and to design and develop assistive engineering and technological devices or tools for this activity.
