Summary: This study compared lumbar loads among different lifting styles and found that stoop lifting led to lower compressive and total loads, higher shear loads, and longer lifting time compared to freestyle and squat lifting.

Summary: Lumbar vertebral tuberculosis presenting with a focal solitary osteolytic lesion is rare, and proper differential diagnosis is crucial. Conservative medical management generally leads to a good prognosis in the absence of neurological deficits and deformities.

Summary: This study quantitatively analyzed the effect of lumbar spinal muscle atrophy on compressive and shear forces on lumbar intervertebral discs using a musculoskeletal modeling approach. The findings showed that muscle atrophy resulted in increased compressive forces on lumbar discs in most postures, but had no significant effect on shear forces.

Summary: Musculoskeletal modeling is a commonly used method in spine biomechanics, providing detailed information on joint loading. A procedure was developed for the automated generation of semi-subject-specific multi-rigid body models, personalized using information from annotated EOS images. The method shows promise for studying clinical questions related to joint loading and pathomechanisms.

Summary: This review evaluates the characteristics of different model elements used in lumbar spine modeling, highlighting the simplifications and limitations of current studies. It suggests combining features from both finite element models and musculoskeletal models to address these issues and develop more comprehensive models.

Summary: This post hoc analysis examined the performance of machine learning models in predicting outcomes for adult symptomatic lumbar scoliosis patients. The results showed that the models performed better than chance in predicting major complications, reoperations, and hospital readmissions.

Summary: This retrospective review analyzed the patterns of opioid use in Medicaid patients undergoing lumbar surgery and identified associated risk factors. The study found that most Medicaid patients were already using opioids prior to surgery and continued long-term use postoperatively. Preoperative and perioperative use, degenerative disk disease, multiple prescribers, depression, and concomitant medications were significant risk factors.

Summary: The study aimed to develop a questionnaire to measure the consequences of neck, midback, and low back pain in schoolchildren aged 9-12 years. Through literature search and qualitative study, a 28-item questionnaire was developed. The study highlighted the importance of combining different research methods in developing the questionnaire.

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: Lumbar spinal stenosis is a commonly diagnosed spinal disorder that often requires surgery in older adults. While conservative and surgical management have limited effectiveness, the use of prostaglandin E-1 analogs in Japan has shown potential benefits for improving symptoms. Further research and comparison with existing treatments are needed before recommending routine clinical use in the United States.

Summary: A modified Delphi approach was used to develop a core musculoskeletal anatomy syllabus specific to physical therapy students. The findings showed that approximately 80% of the anatomical items were considered core/recommended knowledge for physical therapy students, which is higher compared to the syllabi for medical students (approximately 50%).

Summary: This study aimed to evaluate the impact of aerobic training on fatigue and musculoskeletal pain in patients with psoriasis without arthritis. The results showed that a 16-week aerobic training program significantly improved symptoms without increasing markers of muscle damage.

Summary: Musculoskeletal models were used to investigate joint loading during manual material handling, with load mass identified as having a significant impact on lumbar spine compression. Asymmetry led to increased mediolateral shear, while horizontal location and deposit height affected forces in different joints. Notable differences in force trends and magnitudes were observed compared to previous research.

Summary: This study aimed to determine the Oswestry Disability Index (ODI) cutoff for achieving Patient Acceptable Symptom State (PASS) one year after minimally invasive lumbar spine surgery. The analysis found that patients with an ODI lower than 25 are expected to achieve PASS, regardless of age, sex, and preoperative disability. Furthermore, PASS showed significantly higher sensitivity compared to minimum clinically important difference (MCID).

Summary: The objective of this study was to explore the diversity, quality, severity, and distribution of symptoms in patients with radicular pain and a lumbar disc herniation. The study found that patients reported several highly bothersome symptoms, but not all symptoms were described as painful. The study also found a large overlap in symptomatic areas for the L5 and S1 nerve roots.
