Summary: This literature review aims to collate and analyze previous experimental findings on the effect of the rib cage on human thoracic spinal biomechanical characteristics. The results show that the rib cage significantly contributes to the stability and motion behavior of the thoracic spine, particularly in axial rotation and the upper thorax half. This study provides valuable evidence for future biomechanical studies on the thoracic spine.

Summary: The study evaluated the performance of different kinematic constraints for inverse kinematics analysis in spine motion. Results showed that adding more DOF to kinematic constraints did not notably improve performance, with 4-6DOF constraints producing similar levels of smoothness and physiologically reasonable joint ROMs. A kinematic constraint with 5DOF was found to produce smooth spine motions with relatively low marker error.

Summary: Biomechanical properties of the upper thoracic spine were evaluated with anterior-posterior shear loading at various displacement rates. The stiffness of the specimens was significantly higher in the anterior direction compared to the posterior direction, with the shear displacement rate having a minor effect on the load response. The shear stiffness in the upper thoracic spine is greatest in the anterior loading direction due to facet interactions.

Summary: The literature offers various stereophotogrammetric protocols for quantifying the multi-segmental motion of the thoracolumbar spine, but a standard guideline is lacking. From a clinical perspective, the application of these approaches is still limited. Further research is needed to define a precise motion analysis protocol and determine its clinical relevance.

Summary: The geometric alignment of the spine affects stability, biomechanical loading, and pain. Variations in sagittal curvature can lead to different load distributions and range of motion. Finite element modeling reveals that excessive curvatures result in greater stress and reduced disc height, while straighter spines reduce stress. Considering patient-specific sagittal profiles in biomechanical analyses and treatments can provide valuable insights.

Summary: This study aimed to investigate the relationships between rotational and translational stiffness measures in an in vitro model. The results showed poor correlations between these metrics in vivo, suggesting variability in clinical assessments. Clinicians should be aware of the degrees-of-freedom being assessed in the spine as they exhibit independent stiffness values.

Summary: Based on the kangaroo's bipedal locomotion and upright position, it is suggested that the kangaroo could be an interesting model for spine research and a reasonable surrogate for biomechanical in vitro tests. This in vitro study aimed to provide biomechanical properties of the kangaroo spine and compare them with human spinal data. The flexibility of the kangaroo spine was found to be greater overall, with similarities only found in the cervical, lower thoracic, and lumbar regions.

Summary: The range of axial rotation of thoracolumbar spine in macaque monkeys was estimated through both whole-body and bone-ligament preparation conditions. The results showed that the lower thoracic vertebrae had a greater range of rotation, similar to humans, while the upper thoracic vertebrae had a range of rotation similar to that of the lower thoracic vertebrae in the bone-ligament preparation condition.

Summary: In this in vitro study, the optimal screw position in the lateral lumbar vertebra and the effect of bicortical fixation were investigated. The results showed that posterior or middle positioned screws had higher pullout forces than anterior positioned screws, and there were no significant differences between central and lower positions. Additionally, screws with unicortical fixation had significantly lower pullout forces compared to screws with bicortical fixation. Therefore, posteriorly positioned screws with unicortical fixation provided better stability.

Summary: The analysis of single motor unit (SMU) activity is crucial for understanding the neural strategies controlling muscle force. Traditionally, this analysis has been done invasively through intramuscular electromyography (EMG), but recent advances in signal processing techniques have enabled the identification of SMU activity in high-density surface electromyography (HDsEMG) recordings.

Summary: Power for human walking primarily comes from ankle and hip muscles. Adding a 'passive' hip spring to bipedal models can improve efficiency compared to using only push-off impulse, but the energetic costs of hip spring are not well studied. This study simulated a flat-feet model walking at different speeds and found that asymmetric hip actuation can reduce the metabolic cost of transport (MCOT) relative to ankle actuation by up to 6%, but only at medium speeds. Coordinating ankle actuation, hip flexion, and retraction actuation can help reduce MCOT.

Summary: This study examined the activity distribution among the hamstring muscles during the Nordic hamstring exercise (NHE) to better understand its protective mechanism. Muscle activity was measured using electromyography in male basketball players. Results showed heterogeneous muscle activity within the semitendinosus and the semimembranosus, with the highest contribution from the semitendinosus. The biceps femoris long head had significantly lower activity. The findings highlight the importance of the semitendinosus in compensating for the commonly injured biceps femoris long head during the NHE.

Summary: This study investigated the acute effects of stretching on muscle deformation and mechanical properties. It found that constant force stretching had a greater impact on muscle force, stiffness, muscle length, and tendon length compared to constant length stretching. The differences in imposed maximal strain were the main factor affecting these changes.

Summary: Negative pain-related cognitions are associated with persistence of low-back pain (LBP), but the mechanism underlying this association is not well understood. We propose that negative pain-related cognitions determine how threatening a motor task will be perceived, which in turn will affect how lumbar movements are performed, possibly with negative long-term effects on pain.

Summary: Understanding the mechanisms humans use to stabilize walking is crucial for predicting falls in the elderly. Two potential mechanisms, foot placement control and ankle push-off control, have been identified to stabilize gait in the anterior-posterior direction. It is unknown whether the latter mechanism is employed in steady-state walking. This study found that foot placement errors in steady-state walking were correlated to ankle push-off torque, suggesting that humans use a push-off strategy to correct foot placement errors.

Summary: This systematic review found that combined lifestyle interventions are not superior to usual care for improving physical functioning, relieving pain, and improving lifestyle outcomes in overweight or obese individuals with persistent low-back pain. However, these interventions are likely to be more cost-effective in terms of healthcare, medication, and absenteeism costs compared to usual care.

Summary: This study investigates the effects of chronic low-back pain (CLBP) and pain-related cognitions on the impact of mechanical perturbations on trunk movement, as well as the associations between these perturbation effects and movement precision. The findings suggest that negative pain-related cognitions can increase resistance to perturbations, but at the expense of movement precision.

Summary: Trunk extensor muscle fatigue is characterized by a decline in spectral content of surface electromyography, which primarily reflects a decrease in average motor unit action potential conduction velocity. This study found that the linear rate of change in conduction velocity was strongly correlated with trunk extensor muscle endurance time, whereas the correlation between the linear rate of change in spectral measures and endurance time was lower or non-existent. These findings provide guidance for monitoring the development of trunk extensor muscle fatigue using electromyography.
