Summary: This study compares the stiffness properties of ligaments and their impact on the kinematic behavior of a thoracic functional spinal unit. The results highlight the importance of nonlinear characterization in determining proper kinematic behavior in spinal finite element models, and suggest that incorporating costovertebral joints can reduce the variation in range of motion.

Summary: The biomechanical and functional characteristics of the shoulder complex and thoracic spine were analyzed in patients with subacromial impingement syndrome (SIS) compared to healthy individuals. Patients with SIS showed reduced shoulder range of motion (ROM) and limited thoracic extension, as well as alterations in scapular position and decreased shoulder strength. These findings highlight the importance of interventions targeting thoracic extension and scapular position to improve shoulder ROM and muscle strength in the rehabilitation of SIS patients.

Summary: This study characterized spinal cord atrophy in different multiple sclerosis (MS) phenotypes and found that it was prevalent across all MS phenotypes, especially correlated with clinical disability. While cervical spinal cord thinning correlated with most disability and progression measures, including thoracic measurements improved this correlation and allowed for better subgrouping of spinal cord phenotypes. Cord atrophy is an important and easily obtainable imaging marker of clinical and sub-clinical progression in all MS phenotypes, and can play a key role in patient selection for clinical trials.

Summary: In patients with chronic non-specific low back pain, reduced lumbar-hip ratios during reaching tasks and slower reaching times suggest a compensatory movement strategy that may be important in the development and progression of LBP. No significant effects of sex or interactions between group and sex were observed for any outcome.

Summary: The study evaluated the effects of age, pathology, and fusion on bony neural foramen area in cervical radiculopathy. Results showed that neural foramen area decreased with age and pathology, but replacing degenerated disc tissue with bone graft did not change the neural foramen area. Moderate to strong associations between neural foramen area and disc height were observed in middle-aged controls, providing novel insight into the mechanism of pain relief after ACDF.

Summary: The study found that corrective exercise is more effective in improving the condition of patients with thoracic hyperkyphosis, showing better outcomes in increasing muscle strength and endurance, improving the value of Cobb's angle, and increasing the cross-sectional area of deep muscles in the neck.

Summary: This study analyzed the differences in neck kinematics during functional tasks in individuals with chronic neck pain. The results showed that participants with neck pain maintained a more flexed neck posture, had less sagittal range of motion, and had higher velocity peaks when reaching to the left and right and putting on a seatbelt.

Summary: The aberrant cervical count in tree sloths seems to have some impact on the rotational ability of their necks, but it plays a secondary role in overall neck mobility. The rotational capacity of the neck is primarily determined by the anatomy of the vertebrae.

Summary: This study leveraged a validated finite element model of the spine to explore activation strategies based on muscular pressure for maintaining equilibrium spinal stability. Traditional strategies showed efficacy in activating muscles, while novel IMP-based strategies revealed a threshold for individual muscle IMP.

Summary: This study investigated the association between non-traumatic vertebral body fractures and degenerative changes in older patients. The results show that fatty deposits in the lower thoracic and lumbar spine are associated with non-traumatic fractures of the lower thoracic spine, but not with lumbar spine fractures.

Summary: This study compared the kinematics of the spine under in vivo and in vitro loading conditions, finding that the in vitro model had a more anterior instant center of rotation and larger disc heights relative to in vivo. However, after adjusting for gender, the differences in disc height were not statistically significant.

Summary: This study provides in vivo evidence that contradicts long-held beliefs that adjacent segment end-range motion increases appreciably after anterior cervical spine arthrodesis and that two-level arthrodesis exacerbates these effects. Mid-range motion appears to be more useful than end-range motion for detecting early changes in adjacent segment motion after cervical spine arthrodesis.

Summary: This study evaluated the kinematic differences between normal and degenerated cervical spine specimens, and found that the degenerated group had larger angular rotation and displacement in the extension mode. These findings can potentially assist in the early detection of cervical spine degeneration.

Summary: Both velocity-specific and isometric exercises were effective in promoting cervical muscle functions and performance, with no significant differences between the two in various muscle indicators. Velocity-specific exercise demonstrated greater enhancement in neuromuscular efficiency of the cervical extensors.

Summary: This study found that patients with chronic nonspecific low back pain were able to recover to a comparable level of healthy controls in terms of their lumbopelvic movement and motor control pattern after a 6-week rehabilitation program, with more profound and positive changes shown during the flexion phase. The improvement of physical outcome measures suggests that a specific rehabilitation program emphasizing on optimizing motor control during movements would help promoting the functional recovery of this specific low back pain subgroup.

Summary: This study investigates the effects of thoracic erector spinae fatigue on spinal muscle activity and kinematics in individuals with scoliosis. The findings suggest that individuals with scoliosis have higher muscle activation at the convex side after fatigue, which may increase the risk of back pain.

Summary: Wireless accelerometers with different operating ranges have been used to measure tibial acceleration. The results show that low-range accelerometers produce distorted signals and inaccurate measurements of peaks. A restoration algorithm using spline interpolation has been proposed but has not been tested for higher magnitude peaks and resultant peaks.

Summary: This study examined the differences in postural adjustments between erect, hyperlordotic, and swayback postures when facing external perturbations. The findings suggest that adopting hyperlordotic and swayback postures alters the contributions of the active and passive subsystems of the spine in postural control, potentially reducing the spine's ability to withstand loading and shear forces.

Summary: This cross-sectional study aimed to evaluate the associations between electronic device use and the prevalence and severity of musculoskeletal symptoms, visual symptoms, psychosocial health, and quality of life in children and adolescents. The findings showed that excessive electronic device use was associated with increased prevalence and severity of physical and psychosocial symptoms, and this use is more prevalent in adolescents. These findings have important health implications and highlight the need for early intervention to reduce the risk of developing device use-related disorders.
