MRI assessment of the correlation between lumbar physiological curvature and Pfirrmann grading of lumbar intervertebral disc in young patients / 实用放射学杂志

Objective To investigate the correlation between lumbar physiological curvature and Pfirrmann grading of lumbar intervertebral disc in young patients with lower lumbar pain.Methods 1 1 1 cases with lower lumbar pain were analyzed retrospectively by lumbar MRI examination.The MRI image was reviewed by two radiologists,and the degree of lumbar physiological curvature and lumbar disc degeneration were observed.Chi square test was applied to the statistical results.Results Final analysis was performed on 300 discs in 60 cases of patients with lumbar physiological curvature straightening.Among them,209 were grade Ⅰ-Ⅱ(70%),45 grade Ⅲ(15%),35 grade Ⅳ(11%)and 11 grade Ⅴ(4%)in Pfirrmann grading.In total of 255 discs of 51 cases with normal physiological curvature of the spine,there were 212 (83%)of Pfirrmann grade Ⅰ-Ⅱ,22 of grade Ⅲ(9%),19 of grade Ⅳ(7%)and 2 of grade Ⅴ(1 %).There was statistical difference between the lumbar physiological curvature straightening and the normal lumbar physiological curvature group (P< 0.05).The proportions of degeneration of Ⅰ-Ⅱ in the lumbar physiological curvature group was lower than that in normal lumbar curvature group,while the proportions of gradeⅢ,ⅣandⅤdegeneration in the lumbar physiological curvature group were higher than that in normal lumbar curvature group.Conclusion Stratification lumbar physiologic curvature is an important factor for lumbar disc degeneration and easy to cause Pfirrmann gradeⅣ-Ⅴdegeneration in young patients.

The relationship between mechanical low back pain and lumbar curvature angle among computer users.

Aim: To determine the relationship between mechanical low back pain and lumber curvature angle among bank worker computer users. Material and methods: 30 male bank worker computer users were working for continuous 4-hours at least/day, five days/week, selected randomly from National Bank of Egypt, kafrelshiekh governorate, Egypt. They divided into 2 equal groups (A and B). Male in group (A) were suffering from low back pain (LBP) within the last 6 month; male in group (B) were free from LBP. Their age was ranged from 25 to 30 years. Their body mass index was less 30 Kg/m. Lumbar curvature angle and pain intensity were measured by using the flexible ruler and visual analog scale for each participants in both groups (A and B). Results: There were significant differences in participant’s low back pain intensity (P = 0.001) and lumbar curvature angle (P = 0.001) between both groups. There was a statistically significant correlation between the pain intensity in lower back and lumbar curvature angle (P=0.001) between both groups. There was a statistically significant correlation between the pain intensity in lower back and lumbar curvature angle in both group ( A and B) (r = 0.463 and 0.37 respectively), as the pain intensity increased by increased lumber curvatuer angle. Conclusions: The bank worker computer users were more exposed to low back pain due to flattening of lumbar curve.

Repercussões da curvatura lombar nas características da lombalgia em praticantes de voleibol / Lumbar curvature repercussions on lumbar pain characteristics in volleyball players

INTRODUÇÃO: A dor lombar vem sendo um achado comum em atletas e indivíduos adultos jovens. Das diversas causas deste sintoma, as alterações mecânico-posturais estão entre as mais comuns na população. OBJETIVO: Este estudo foi realizado com o intuito de correlacionar a intensidade e os aspectos da lombalgia com as medidas angulares da curvatura lombar em praticantes de voleibol. MÉTODOS: Participaram desta pesquisa 42 jovens atletas, de ambos os sexos, com idade entre 14 e 18 anos, divididos em dois grupos, o grupo sem dor e o grupo com dor lombar. Ambos responderam a uma ficha de avaliação inicial, porém a escala analógica visual de dor foi aplicada apenas nos indivíduos do grupo com dor. A seguir, todos os participantes foram submetidos ao exame radiológico da coluna lombar e o ângulo de Cobb foi obtido sobre as radiografias no plano sagital. RESULTADOS: Os resultados foram analisados através da estatística descritiva e inferencial, demonstrando que, para p < 0,05, os valores médios dos ãngulos entre os dois grupos analisados não diferem significativamente. CONCLUSÃO: Conclui-se que não houve correlação entre a curvatura da coluna lombar e a lombalgia em jovens praticantes de voleibol.

INTRODUCTION: Although not frequent, lately there have been cases of young adults and athletes complaining of lumbar pain, this being one of the most common causes of mechanical postural alterations. OBJECTIVE: In view of this, it was decided to carry out this study correlating the intensity of lumbar pain with its anatomical/physiological characteristics, using the measurements of the angles of lumbar curvature in volleyball players. METHODS: 42 athletes including males and females from 14 to 18 years of age took part. These volunteers were divided into two groups according to the symptoms of their lumbar pain: one group with lumbar pain and the other with no lumbar pain. The initial procedure for both groups was to complete a structured functional assessment form. Only the group with lumbar pain then had the visual analogical scale of pain applied. After this stage, both groups were submitted to a radiological examination of the lumbar region of the spine, which was used to calculate the Cobb angle examining the x-rays on the sagital plane. RESULTS: The results were analysed using descriptive and inferential statistics, regarding as statistically significant p<0.05 the difference of the mean values of the angles found in the measurements taken in the two groups. Statistical analysis using the qui-square test, the likeli hood ratio test and Student's t-test showed no statistically significant difference. CONCLUSION: this study concluded that the differences found through the measurement of curvature of the lumbar region of the spine have no influence on the appearance and the intensity of lumbar pain in young volleyball players.

A clinic study of trunk muscle strength and lumbar curvature in young patients with low back pain / 中华物理医学与康复杂志

BIOMECHANICAL STUDY OF TRUNK MUSCLE STRENGTH AND INTERRELATED STUDY IN PATIENTS WITH LOW BACK PAIN CAUSED BY MILITARY TRAINING / 解放军医学杂志

To ascertain the change of trunk muscle strength and lumbar curvature and cross sectional area of M. sacrospinalis in low back pain caused by military training, the indexes of trunk muscle strength (PT/BW, TAE, F/E) were measured in patients with low back pain and healthy subjects with CYBEX 6000 isokinetic testing system. The lumbar curvature was measured in lumbar X ray films on the lateral projection in standing position, and the cross sectional area of sacrospinalis was measured by ultrasonography. All of the indexes were compared between the two groups.The results showed PT/BW of flexors was not significantly different between the patients and healthy subjects, TAE of flexors in patients was lower than that of healthy subjects ( P

Study of the lumbar curvature with various factors of pelvic inclination. Change of radiographic lumbar curvature according to hip joint flexion

The objective of this study was to investigate the influence of the hip flexion upon parameters that are indicators of spinal mobility. These parameters include intervertebral disc angle and lumbar curvature by measurement of the radiography in twenty eight healthy men. The state of knowledge of how these parameters relate to lumbar mobility have resolved. The results of the parameters showed negligible changes in relation to the mobility of lumbar spine according to angle of hip flexion except at L4-L5 intervertebral disc angle and lumbar curvature (p< 0.05). This results of study confirms that hip joint movement therapy can be applied to these norms in patient management in supine position of for the stable spinal injuries in the upper lumbar region during early phase.

The change in trunk muscle performance in recruits with low back pain caused by military training and its prevention / 解放军医学杂志

To elucidate the change in trunk muscle performance in patients with low back pain caused by military training. The indices of trunk muscle strength (PT/BW, TAE, F/E, ER), the cross-sectional area of sacrospinalis, the amplitude and the duration of EMG, and the lumbar curvature were measured in recruits with low back pain after military training (n=40)and healthy subjects(n=40).All of the indices were compared between two groups. It was found that except PT/BW and ER of flexors and cross-sectional area of sacrospinalis, there were significant differences between other indices of the patients compared with healthy subjects(P
