AbstractThe retrospective study aimed to investigate the relationship between lumbar lordosis morphology, pelvic incidence and paraspinal muscle. It enrolled asymptomatic adult volunteers aged between 18 and 45 years old. Lumbar lordosis morphology, consisting of total lumbar lordosis (LL), proximal lumbar lordosis (PLL), distal lumbar lordosis (DLL), lumbar lordosis apex (LLA) and inflexion point, was evaluated, as well as pelvic incidence (PI) and muscularity of erector spinae (ES) and multifidus. Pearson correlation was performed to analyze the relationship between each other parameter. Cases were stratified according to pelvic incidence (very low < 30°, low 30°–45°, moderate 45°–60°, and high > 60°), comparison between groups was performed by univariance analysis. 87 asymptomatic adult volunteers (33 females and 54 males) were included in the study. PLL revealed a correlation with LLA (r = 0.603, p = 0.002) and inflexion point (r = 0.536, p = 0.004), but did not DLL with LL apex (r = 0.204, p = 0.058) or inflexion point (r = 0.210, p = 0.051). PI revealed a greater correlation with PLL (r = −0.673, p < 0.001) than with DLL (r = −0.237, p = 0.045). Linear stepwise regression analysis also exhibited the correlation between PI and PLL (R2 = 0.452, PLL = 16.2–0.61 * PI, p < 0.001). ES muscularity correlated with LL apex (r = −0.279, p = 0.014) and inflexion point (r = −0.227, p = 0.047). Stratification by PI demonstrated PLL increased across groups (p < 0.001), but DLL was comparable between low and moderate PI group (p = 0.329). Lumbar lordosis morphology appears to accommodate to pelvic incidence and erector spinae muscularity. Proximal lumbar lordosis has a bigger correlation with pelvic incidence than the distal lumbar lordosis. The results are helpful for restoring a rational lumbar lordosis shape in long fusion surgery.

Abstract Background It is still blank on the relationship between lumbar lordosis morphology and paraspinal muscle in asymptomatic Asian adults. The study aims to investigate the relationships. Methods 87 asymptomatic adults aged between 18 and 45 years old were enrolled in the retrospective study. Lumbar lordosis morphology, consisting of total lumbar lordosis (LL), proximal lumbar lordosis (PLL), distal lumbar lordosis (DLL), lumbar lordosis apex (LLA) and inflexion point (IP), was evaluated, as well as pelvic incidence (PI) and muscularity of erector spinae (ES) and multifidus (MF). Pearson correlation was performed to analyze the relationship between each other parameter. Cases were stratified according to pelvic incidence (very low < 30°, low 30°-45°, moderate 45°-60°, and high > 60°), comparison between groups was performed by univariance analysis. Results PLL revealed a correlation with LLA (r = 0.603, p = 0.002) and inflexion point (r = 0.536, p = 0.004), but did not DLL with LL apex (r = 0.204, p = 0.058) or inflexion point (r = 0.210, p = 0.051). PI revealed a greater correlation with PLL (r=-0.673, p < 0.001) than with DLL (r=-0.237, p = 0.045). Linear stepwise regression analysis also exhibited the correlation between PI and PLL (R2 = 0.452, PLL = 16.2–0.61*PI, p < 0.001). ES muscularity correlated with LL apex (r=-0.279, p = 0.014) and inflexion point (r=-0.227, p = 0.047). Stratification by PI demonstrated PLL increased across groups (p < 0.001), but DLL was comparable between low and moderate PI group (p = 0.329). Conclusion Lumbar lordosis morphology correlates to erector spinae muscularity. Proximal lumbar lordosis has a bigger correlation with pelvic incidence than the distal lumbar lordosis. The results are helpful for restoring a rational lumbar lordosis shape in long fusion surgery.

Abstract Objective To measure the sagittal configurations of the sacrum using computed tomography (CT), and to investigate the correlation between the sagittal configuration of the sacrum and pelvic incidence. Methods The computed topographies of complete pelvic imaging between 2006 and 2018 was retrospectively studied. Measurements of pelvic and sacral morphological parameters were performed on the midsagittal plane of the 2D reconstruction images of computed tomography. Pelvic incidence (PI) (STA) were measured as previously described, and sacral table angle, sacral incidence (SI), sacral segmental vertebral angle (SSVA), sacral segmental kyphosis (SSK), central angle (SCA), arc length (SAL) as well as arc radius (SAR) were introduced to describe the segmental morphology of sacrum. Pearson Correlation Coefficient and Stepwise Regression Analysis were used to determine the relationship between PI and sacral morphological parameters. Results A total of 304 subjects were finally included in this study. The average age of the patients were 46.22 ± 15.92 years, and the average PI was 45.24±8.68°. Most of the sacral morphological parameters were not different as affected by gender or age. The morphological parameters of S1: S1I, SSVA1 and STA were finally confirmed to be closely correlated with PI, while no significant correlation between sacral curvature (SCA) and PI was identified, and morphological parameters of other sacral segments were not correlated to PI either. Conclusion The morphological parameters of S1 are more closely correlated with PI, and the sacral incidence of S1 might serve as a useful tool for the calculation of PI.

Background: The researchers and clinicians are emphasizing on function of Transverse Abdominis (TrA) which is a deepest abdominal muscles because there is an evidence that TrA is recruited independently of the other abdominal muscles in many different tasks and plays an important role in lumbar stability. Aim: The purpose of this study was to assess the relationship between TrA muscle strength and lumbar lordosis in young adults. Methods: Total 394 subjects were recruited from the constituent institutions of Sumandeep Vidyapeeth with the age range 18-35years. All the subjects, Lumbar lordosis angle and their TrA strength were measured with the Flexicurve and Pressure Biofeedback Unit respectively. Lumbar lordosis angle was calculated using established formula. Average of 03 trials was considered for TrA strength. Results: Pearson correlation coefficient was -0.18 on correlating Lumbar lordosis angle with TrA strength, -0.09 for age with TrA strength and 0.11 for age with lumbar lordosis angle. Conclusion: This study concludes that there is negative relationship between lumbar lordosis and TrA i.e. as the lumbar lordosis angle increases, the strength of TrA muscle decreases.

This is a study on employees’ perception of justice towards performance-based pay and the effect of these perceptions on their turnover intention. This study aims to examine the mediating role played by distributive and procedural justice in linking pay distribution and pay procedure of performance-based pay to employees’ turnover intention. A review of past literature in this particular area has prompted the researchers to narrow the gaps in previous studies. Towards that, this study utilized questionnaires which were administered among 50 non-managerial employees currently working in a private company located in Kuching, Sarawak, East Malaysia. Data analysis was done using Statistical Package for Social Sciences (SPSS), Version 20.0. Pearson Correlation and Stepwise Regression were used to examine the relationship between the variables. The outcomes of Stepwise Regression revealed that distributive justice fully mediated the relationship between pay distribution and employees’ turnover intention in contrast to procedural justice which did not have a significant impact in the relationship. The findings of this study are useful references for organisation management of the pay system to improve employees’ performance.Keywords: employees’ turnover intention; organizational justice; performance-based pay

Although many studies have investigated the relationship between perfectionism and anxiety among the adults, little is known about the manifestations of the effects of parent perfectionism on anxiety of children in Iran. This study was conducted to examine the relationship between positive and negative perfectionism of mothers whit anxiety of their children in an Iranian sample. Besides the study of effects of mother's perfectionism and how can make serious problems for their children is another aim of this research. The study was consisted of 150 women of Refah Bank employees and their 8–15 years old children, which were selected by a multi-stage random cluster sampling. In order to evaluation, the positive and negative perfectionism scale and the revised children's manifest anxiety were assessed. After data collection, Pearson correlation and stepwise regression, using SPSS were conducted. Results showed that positive perfectionism of mothers was not correlated significantly with their child's anxiety. However, mothers’ negative perfectionism was associated positively with children anxiety which was significant at 0.01 probability level. Analysis of stepwise regression showed that mothers’ perfectionism predicted anxiety of their child. It can be concluded that negative perfectionism of mothers can directly and indirectly have negative effects on children and provide serious problems for them. Our findings indicate that although we must take care of unhealthy and neurotic consequences of negative perfectionism but positive striving for perfection can help us to improve in some aspects.Disclosure of interestThe author has not supplied his/her declaration of competing interest.

Abstract Background: Ankylosing spondylitis (AS) patients with kyphosis have an abnormal spinopelvic alignment and pelvic morphology. Most studies focus on the relationship of pelvic tilt (PT) or sacral slope (SS) and deformity, and relatively few studies have addressed the relationship between pelvic incidence (PI) and kyphosis in AS patients. The purpose of this study is to analyze the correlation between pelvic incidence (PI) and the spinopelvic parameters describing local deformity or global sagittal balance in AS patients with thoracolumbar kyphosis. Methods: A total of 94 patients with AS (91 males and 3 females) and 30 controls were reviewed. Sagittal spinopelvic parameters, including PI, PT, SS, thoracic kyphosis (TK), thoracolumbar kyphosis (TLK), lumbar lordosis(LL), sagittal vertical axis(SVA), the first thoracic vertebra pelvic angle(TPA), spinosacral angle(SSA) and spinopelvic angle(SPA) were measured. Pearson correlation (r) and unary linear regression model were used to analysis the relationship between PI and other spinopelvic parameters. Results: Compared with the control group, the AS patients had significantly higher PI(47.4˚ vs. 43.2˚, P<0.001). PI in AS patients was found to be significantly positively correlated with TPA(r=0.533, R2=0.284, P<0.001), and negatively correlated with SPA(r=-0.504, R2=0.254, P<0.001). However, no correlations were found between PI and SVA, SSA, TK, TLK or LL in AS patients. Conclusion: This study revealed that increasing PI was significantly correlated with more global sagittal imbalance, not with the local deformity in AS patients with thoracolumbar kyphosis. Key Words: ankylosing spondylitis, pelvic incidence, sagittal spinopelvic parameters, global sagittal balance
