“…In a study of herniated nucleus pulposus (HNP) patients, SY Ma et al reported that values for lumbar lordosis, disc angle, disc height, and lumbosacral angle were lower than those found in normal adults 13) . In the present study, which evaluated normal young adults, SA increased together with Lo, Ex, and RFEM.…”

Abstract. [Purpose] This study investigated the correlations among sacral angle (SA), lumbar lordosis (Lo), maximum contractility of the transverse abdominis (TrA), and the static and dynamic lumbar stability (SLS and DLS) in college students in their 20s.[Subjects] The subjects were 40 college students (20 males and 20 females) in their 20s.[Methods] Lateral view radiographs were used to analyze the SA, Lo, flexion (Fle), extension (Ex), and the range of Fle and Ex motions (RFEM). The PBU (Pressure biofeedback unit) was used to examine SLS and DSL. The Oswestry Disability Index (ODI) was used to evaluate lumbar pain and physical functions.[Results] As SA increased, Lo, Ex and RFEM increased. As Fle increased, RFEM increased while ODI decreased. The results of this study indicate that as Ex increases, RFEM and DLS also increase, and as RFEM increases, DLS increases while ODI decreases.[Conclusion] The results indicate that the lumbar spine's posture and range of motion affects DLS rather than SLS. In particular, it is thought that therapeutic approaches for increasing Ex and RFEM should be considered.

“…These heat maps show that the disk and surrounding structures may be important for the prediction model of lumbar HNP based on deep learning. Abnormal spine alignment can be associated with HNP in L4-5 [ 20 ]. In Figure 1 c, the heat map was stronger in the facet joint of L4-5 and L5-S1.…”

Lumbar herniated nucleus pulposus (HNP) is difficult to diagnose using lumbar radiography. HNP is typically diagnosed using magnetic resonance imaging (MRI). This study developed and validated an artificial intelligence model that predicts lumbar HNP using lumbar radiography. A total of 180,271 lumbar radiographs were obtained from 34,661 patients in the form of lumbar X-ray and MRI images, which were matched together and labeled accordingly. The data were divided into a training set (31,149 patients and 162,257 images) and a test set (3512 patients and 18,014 images). Training data were used for learning using the EfficientNet-B5 model and four-fold cross-validation. The area under the curve (AUC) of the receiver operating characteristic (ROC) for the prediction of lumbar HNP was 0.73. The AUC of the ROC for predicting lumbar HNP in L (lumbar) 1-2, L2-3, L3-4, L4-5, and L5-S (sacrum)1 levels were 0.68, 0.68, 0.63, 0.67, and 0.72, respectively. Finally, an HNP prediction model was developed, although it requires further improvements.

“…Despite various studies conducted around the world on the normal range of thoracic kyphosis, each region seems to need its value. Additionally, with increasing lordosis, spine biomechanics changes led to its non-alignment due to increased loading on the facet joints and increased shear force at the lumbosacral junction [25][26][27][28].…”

The quality and condition of the human body are of particular importance. This is because the positive and negative changes resulting from this matter could affect other conditions. The skeletal condition of the spine is an essential part of a person's physical condition.Recognizing correct positions has always attracted the attention of sports scientists. The present study reviewed the normative data of the thoracic and lumbar curvature. Methods:We investigated the studies conducted from 1980-2016. We studied and used related articles that measured spinal curvatures and investigated invasive and non-invasive methods. The authors reported previous studies without any bias. Results:The obtained results indicated that spine norms are different in research reports. Thus, further investigating this subject is required for recognizing, categorizing, screening, and decreasing the prevalence of spinal deformities. Conclusion:We reviewed the studies on the prevalence of spinal abnormalities and the provision of natural alignment and the extent of injury to the area in athletes. The relevant data suggested a great variation in applying measurement methods, as well as the homogeneity between the studied communities. Therefore, comparing the present results and categorizing studies should be performed with great caution.
