Summary: This study used a subject-specific musculoskeletal model and a high-accuracy intact finite element knee model to evaluate the kinematics and mechanics of an intact knee joint during the gait cycle. The results showed that internal rotation and parallel anterior translation are important movements for the normal function of the knee joint. Furthermore, the majority of the joint load is borne by the cartilage-cartilage contact, and there is significant contact pressure on the patellofemoral joint. These findings provide important theoretical foundations for the treatment of knee joint diseases and the design of knee prostheses.

Summary: The study found that after quadriceps fatigue, the extension and adduction moments of the knee joint, as well as the mean anterior bundle of ACL force, decreased significantly; while after hamstring fatigue, the knee flexion angle, knee valgus angle, and shear force decreased significantly. Muscle-specific fatigue may lead to ACL injury, but the hamstring muscle may not have a mechanism to prevent ACL injury.

Summary: Thermal strain imaging (TSI) is a valuable technique for estimating temperature changes, but physiological motions can introduce artifacts. In this study, a respiration separated TSI (RS-TSI) method is proposed, which uses normalized cross correlation (NXcorr) coefficient and frame selection to improve motion compensation and reduce the output time interval.

Summary: This study proposed an objective identification and description of different phases in a drilling task, and evaluated the overall posture of subjects using biomechanical and ergonomic analysis. Results showed that increasing height doubled the duration of the drilling phase while reducing exerted force, and significantly influenced subjects' posture. The risk of developing MSDs was found to increase with height variation.

Summary: The aim of this research was to investigate whether ergonomic instruction conducted by a physiotherapist would change the range of motion of the lumbar spine segments and the symmetry of muscle work in the torso and upper limbs of foundry employees. The results showed that ergonomic instruction reduced contralateral muscle imbalance and changed the range of movement in the lumbar spine segments.

Summary: The study compared the biomechanical performances of two potential anatomic ankle implants and a commercial INBONE II implant during walking, showing significant improvements in kinematic functions and load balance with the anatomic ankle implants. The height difference between the medial and lateral borders also had an impact on ankle biomechanics and kinematics, with the design of anatomic ankle implant with the medial peak higher than the lateral peak showing better performance.

Summary: The study reported problems encountered when using data gloves to record hand kinematics and determined an appropriate hand size. Results showed that the minimum hand length for proper recording was 184 mm, and validation experiments were conducted to compare the results with those in the literature. Although the glove fit properly, some issues such as difficulty recording small flexion angles or diminished touch sensitivity remained, indicating potential usability improvement with availability of different glove sizes.

Summary: This study developed a musculoskeletal model of the whole equine forelimb and verified it using kinematic data, showing reasonable agreement with previous literature in joint excursions and tendon/ligament strains. Strain patterns matched previous reports, with peak strains occurring at specific points in the gait cycle. Differences in strain amplitudes compared to earlier models were discussed in relation to variations in methods and attachment points of tendons and ligaments.

Summary: Thoroughbred racehorses are often affected by musculoskeletal injuries, with track surface hardness and consistency being major risk factors. A musculoskeletal model of the equine forelimb was tested on two perturbing surfaces, showing different responses in shoulder flexion, elbow and carpal flexion, and strain on ligaments and muscle-tendon units. Changes in ground surface affect both the perturbed stance phase and the following stance phase.

The trunk lean modification showed fewer secondary changes compared to toe-in and medial knee thrust modifications, while toe-in and medial knee thrust gait demonstrated similar kinematic relationships.

Summary: The study examined the one-year test-retest reliability of component scores in the Child Sport Concussion Assessment Tool 5th Edition (SCAT5) and provided recommendations for interpreting change. The results showed that the reliability coefficients of SCAT5 component scores were poor to moderate over a one-year period. However, most children were classified within the same interpretive category upon re-testing based on local norms.

Summary: This study investigates how changes in synchronization performance during cueing training affect gait variability measures. The results show that a fast tempo decreases synchronization performance and leads to increased gait variability. This highlights the importance of measuring synchronization performance in clinical research using fractal-like metronomes.

Summary: Gait modifications, such as LTL, MKT, and TIG, are investigated interventions for knee osteoarthritis. The Lerner knee model can estimate the effects on joint reaction forces in the knee during gait. The study suggests that all gait modifications may decrease the joint reaction forces compared to normal gait.

Summary: After ACL reconstruction, athletes often undergo prolonged rehabilitation, but few return to their preinjury sports activities. The nature of an ACL rehabilitation program is important for rehabilitation outcomes, but details about ACL-RPs are inconsistently reported in research studies. To support clinical translation and implementation of ACL-RPs, it is necessary to describe the nature, reporting, and outcomes of ACL-RPs in the current literature.

Summary: There have been significant advances in biosignal extraction techniques for driving external biomechatronic devices or using as inputs to sophisticated human machine interfaces. This paper investigates the control trajectories derived from sonomyography, a sensing paradigm based on continuous ultrasound imaging of forearm muscles. The results show that the time course of these control trajectories reflects the typical kinematic characteristics observed in biological limbs, with similar velocity profiles and time to target. The findings have important implications for the development of control paradigms for assistive technologies.

Summary: This paper proposes a personalized mechanism-based assessment model based on available evidence to identify the underlying pathologies associated with chronic non-specific low back pain. The model suggests that central sensitization can have downstream effects on the myofascial unit, leading to clinical findings for non-specific low back pain. The proposed model offers a comprehensive evaluation that is personalized and feasible, providing guidance for clinically relevant management and future research on mechanisms underlying low back pain.

Summary: Noninvasive methods for estimation of joint and muscle forces, such as surface electromyography (sEMG), suffer from limitations such as poor signal-to-noise ratio and limited spatiotemporal specificity. This paper proposes a sonomyography or ultrasound imaging-based offline approach to estimate continuous isometric force, which reduces the computational complexity and improves the performance compared to traditional ultrasound-based methods. The study shows that Gaussian process regression models outperform other methods in predicting force levels. These findings can contribute to the design of wearable and efficient sonomyography-based force prediction systems.
