Summary: In human walking, the maintenance of whole-body angular momentum (WBAM) is achieved through intersegmental cancellation and external forces. This study provides a comprehensive dataset on WBAM, segmental angular momentum, and external moments during walking to investigate its regulation. The results show that WBAM is regulated by both intersegmental cancellation and contributions from ground reaction forces. While the magnitude of vertical free moments is smaller than the peak vertical moment generated by ground reaction forces, it plays a critical role in coping with changes in vertical WBAM during the single-support phase.

Summary: The study showed that the integrity of the pectineal ligament plays a significant role in the stability of the anterior pelvic ring, especially in the presence of a pubic ramus fracture. Cutting the pectineal ligament significantly increased relative fracture movement and absolute vertical displacement.

Summary: This study compared the effectiveness of the Supraacetabular External Fixator (SEF) and the Subcutaneous Iliopubic Plate (SIP) in treating Fragility Fractures of the Pelvis (FFP) type Ia. The results showed that the SIP was superior to the SEF in reducing the osteotomy's spatial interfragmentary displacement (SID) and the strain in the posterior pelvic ring.

Summary: In this paper, a network model called RA(2)-Net is proposed for accurate segmentation of lumbosacral plexus in spinal MRI images. The model integrates different features of the images through methods like multi-scale feature learning, residual connections, and scale attention blocks, and achieves better performance compared to other methods in experiments.

Summary: The study aimed to investigate the differences in gait characteristics between stroke patients and healthy controls using a newly defined distance in the lower limb. Results showed that stroke patients exhibited less shortening of the pelvis-toe distance on the affected side and excessive shortening on the non-affected side compared to controls. Additionally, PTDmin in stroke patients was found to have moderate to high correlations with gait speed and observational gait scale.

Summary: The study found that the degree of socket adduction in transfemoral amputees significantly affects pelvic and trunk stabilization during level ground walking, with 6±1 degrees of socket adduction appearing to be appropriate. These results provide insights for guiding rehabilitation training and socket alignment in amputees.

Summary: Pelvic fractures are increasingly common and burdensome injuries in the older population. Early fixation for certain types of pelvic fractures improves outcomes, but current practice still mostly involves conservative management. There have been recent developments in surgical stabilization techniques and medical trials for fragility fractures of the pelvis. This article explores the potential of these advancements in improving the morbidity and mortality associated with these fractures.

Summary: This study aims to identify an MRN sequence that can better assist in delineating the lumbosacral plexus nerves and assessing radiation dose. The Lr_NerveVIEW sequence performed better than the Cs_NerveVIEW sequence in nerve visualization. It is important to measure the dose in the LSP to understand the potential impact on treatment-induced neuropathy.

Summary: The study demonstrated that an endurance-dominated exercise program can improve VO(2)max and diabetes-related abnormal gait in patients with DN. The decreases in peak vertical ground reaction force during heel contact of walking may be due to increased activities of vastus lateralis and gluteus medius during the loading phase. Therefore, implementing endurance-dominated exercise programs in type 2 diabetic patients is recommended as it is feasible, safe, and effective in improving aerobic capacity and gait characteristics.

Summary: Despite the initial assumption that wider hips lead to increased energy expenditure while walking, our study using a musculoskeletal model and evaluating 752 trials found no correlation between hip width and total abductor energy expenditure. However, we did find that maximum hip joint coronal plane moment is predicted by pelvic width and, in combination with mass and velocity, explains 79% of the variation. These results indicate that people use their morphology to limit differences in energy expenditure and intraspecific variation may not be useful in understanding species differences.

Summary: The study introduced an algorithm for accurate visualization and assessment of major LSP bundles using the segmentation of the cauda equina, enabling fiber tractography of the LSP and showing good correspondence with MR neurography. The use of normalized quantitative anisotropy instead of fractional anisotropy in the algorithm allowed better separation of muscle and nerve fibers, providing high quality reconstruction of the LSP bundles for research and clinical practice.

Summary: The study based on Korean National Health Insurance claims data from 2008 to 2018 showed an increasing trend in the incidence of Bell's palsy. Risk factors for Bell's palsy included age (60-69 years), sex (male), and month (January). Recurrence rate of Bell's palsy was 1.5% over an 11-year period, with male sex and physiotherapy being independently associated with the recurrence of the disease.

Summary: In the Korean population, the effects of EP-CCRT on OS and TFST are significantly more favorable than those of IP-CCRT. Dual-agent chemotherapy provides a better survival benefit than single-agent chemotherapy when CCRT fails. IP-based chemotherapy leads to better OS in platinum-resistant relapsed patients, while the opposite is observed for platinum-sensitive relapsed patients.

Summary: This study aimed to investigate the levels of physical activity and sedentary behavior, and the factors associated with these, in middle-aged and elderly stroke survivors without limitations to their physical activity. The findings showed that compared to survivors of ischemic heart disease and healthy controls, stroke survivors spent less time in aerobic activity and more time in sedentary behavior, and environmental factors had a significant impact on their levels of physical activity and sedentary behavior.

Summary: This study investigated the association between sociodemographic and health-related factors and health checkup participation in community-dwelling stroke survivors. The findings showed that insufficient physical activity, current smoking, low education level, living alone, and no occupation were negatively associated with health checkup participation. The study concluded that policies and further research are needed to promote health checkups for stroke survivors who have these risk factors.

Summary: We examined self-reported reasons for activity limitations among Korean stroke survivors, considering age and sex differences. Data from 1547 stroke survivors who participated in a survey were analysed. The results showed that older and female stroke survivors reported more reasons for activity limitations compared to younger and male survivors, which differed by age and sex. A tailored approach considering age and sex is necessary to help stroke survivors with activity limitations, highlighting the importance of considering demographic factors in interventions to improve their quality of life.

Excessive alcohol drinking and cardiovascular disease were independently associated with sedentary behavior in individuals with diabetes, while cancer and past smoking were independently associated with sedentary behavior in individuals without diabetes. Obesity, insufficient aerobic exercise, smoking, and arthritis were consistently associated with sedentary behavior regardless of diabetes status.

Summary: This study aimed to identify factors independently associated with prolonged sedentary times in Korean older adults. The findings revealed that advanced age, female sex, unemployment, living alone, urban residence, and insufficient aerobic exercise were all associated with long sedentary times. In addition, obesity, diabetes, cardiovascular diseases, and arthritis were positively associated with long sedentary times. Tailored interventions that consider various sociodemographic, behavioral, and health factors are needed to reduce sedentary behavior in this population.

Summary: Radiographic hip osteoarthritis is rare in Korean middle-aged and elderly population, with a higher prevalence in older age groups and males. Comorbid musculoskeletal pain, such as knee pain, is associated with painful hip osteoarthritis. Hip pain is less common in radiographic hip osteoarthritis, and its severity is more related to men than women.
