Abstract
Objectives: The purpose of this study was to investigate the relationship between the general hyper mobility index with foot arch. Design: Descriptive Correlational Design Methods: Fifty healthy female students participated in the study and general hyper mobility and size of foot arch was measured. Results: The results of the study showed that there was a significant relationship between the general hyper mobility and foot arch (r=0/249 p=0/05). Conclusion: The subjects with greater general hypermobility have lesser foot arch. The significant relationship between the general hyper mobility and foot arch may be due to ligament laxity.

Abstract
Objective: The present study designed to investigate the incidence of spinal deviations among the female students resident in Ashrafi Esfahani dormitory, the university of Social Welfare and Rehabilitation sciences in 2011 and to determine its relation to low back pain and Body Mass Index (BMI). Materials & Methods: In a prospective cross-sectional study 63 female students were randomly included. Before the main study, the reliability of measurements was evaluated. Following giving information about the study, data on background, Back problems and spinal deviations was collected through interviews, questionnaires and physical examination. Data Analyzed with SPSS software using the Pearson Chi-square test and Fisher Exact. Results: The reliability of results were acceptable. Most of quantitative data were consistent with a normal distribution. Out of 63 participants, 38.1% with scoliosis, 27% hyperlordosis and 30.2.% hypolordosis were determined. More than half (58.7 %) of students reported low back pain with severity of 2.19. The results of statistical analysis showed among the students with scoliosis, low back pain (LBP) were less common (27.70%) in comparison with those without scoliosis (72.29%) although this difference was not statistically significant. LBP were 37.83% among individuals with hyperlordosis, 21.63% among those with hypolordosis and 40.54% among those with normal lordosis, this difference was significant (p<0.05). Chi squere result revealed significat relation between LBP with lordosis among female students (p = 0.04) and lordosis with scoliosis (p =0.03), but no significant relation was seen between scoliosis with back pain (p = 0.08), and Body Mass Index (BMI) with scoliosis (p =0.68) and lordosis (12/0 p = 0.12). Conclusion: Among the study population, scoliosis was more prevalent than hyperlordosis and hyperlordosis was more common than hypolordosis. Considering lack of any relation between scoliosis and LBP, scoliosis can be developed without any back pain symptom. And also considering higher prevalence of hyperlordosis and its positive relation to LPB in comparison to hypolordosis, screening, prevention and treatment strategies to specially prevent and&or reduce scoliosis and hyperlordosis are emphasized. This study was confimatory to the relation between scoliosis and lordosis but not confirmatory to the relation betweed BMI with scoliosis and lordosis.

Abstract
Purpose: Considering the role of spine in protecting the body alignment and various body activities, this study aims to examine the relationship between the spine curvature disorders and resting habits among the students of the University of Social Welfare and Rehabilitation Sciences.
Methods: In this correlational study, a total of 108 students of Tehran University of Social Welfare and Rehabilitation Sciences, aged 18 to 29 years, were selected through simple random sampling method. Their curvatures of their spines were measured by scoliometer and a flexible ruler, and their resting habits were assessed through the Resting Habits questionnaire. The obtained data were analyzed by performing Kolmogorov-Smirnov, linear regression, Pearson, Spearman, Mann-Whitney, and Independent t statistical tests using SPSS.V22.
Results: There was no significant relationship between the resting habits of the study participants with their degrees of lordosis (P=0.858, r=0.574) and degree of scoliosis (P=0.603, r=0.857). However, there was a significant relationship between lordosis and gender (P<0.001) and age (P<0.022, r=0.22) in a way that the spine curvature disorders were more prevalent in girls and older students than boys and younger ones.
Conclusion: In this study, the resting habits were not identified as risk factor for abnormal spine curvatures in the younger ages. However, bad resting habits at older ages and in females can be risk factors for lordosis.

Abstract
Purpose: 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.

Abstract
Purpose: Lumbar hyperlordosis is one of the main physical abnormalities that occur in the lumbopelvic region and affect the body movement system in daily life. This condition can also lead to chronic injuries and pain. The present study aimed to investigate the ability of the nine-test screening battery to predict the incidence of lumbar hyperlordosis in adolescent boys.
Methods: This causal study described and analyzed the data with a cross-sectional design. In this regard, 60 adolescents (age range: 13 to 15 years) were selected. After the initial assessments, they were assigned into two groups: the lumbar hyperlordosis group (n=31) and the normal lordosis group (n=29). The angle of lumbar lordosis curvature and functional movements were measured using a flexible ruler and the nine-test screening battery instruction, respectively. The obtained data were analyzed using the logistic regression test at a significance level of 0.05, in SPSS v. 24.
Results: The examination of the coefficients of predictive variables showed that the Wald test is statistically significant for deep squat (P=0.023) and straight leg raise (P=0.033). Also, these variables significantly contribute to the predictability of the model and the likelihood of lumbar hyperlordosis.
Conclusion: Based on the results, the nine-test screening battery can predict the occurrence of lumbar hyperlordosis in adolescent boys through the components of deep squat and straight leg raise.

Abstract
Purpose: Mental exercise uses the same neuronal pathways involved in physical exercise to modify the pattern and function without stress caused by physical exercise. This study investigates the effect of kinesthetic imagery, active, and combined exercises (imagery and active) on the hip hyperextension and the power of selected lumbopelvic muscles in women suffering from lumbar hyperlordosis.
Methods: In this quasi-experimental study, 36 women with lumbar hyperlordosis (age range: 30-40 years, non-athlete and without injury and surgery in the lumbar region) were selected and divided into three groups. The groups practiced three sessions per week for six weeks. We assessed the lumbar lordosis by a flexible ruler and the electromyographic (EMG) activity of the lumbopelvic muscles during hip hyperextension in the prone position by surface electromyogram. We also measured the power of the gluteus maximus using a dynamometer during hip hyperextension and the abdominal muscles using a goniometer during the double leg lowering test. All of the measurements were done before and after the intervention. The normality of the data was checked by The Shapiro-Wilk test, and the obtained data were analyzed by repeated-measures ANOVA test at the significant level of 0.05.
Results: The variables of lumbar lordosis were significantly reduced in the active and combined groups in the post-test compared to the pre-test, and the strength of gluteus and abdominal muscles in the active and combined groups in the post-test significantly increased compared to the pre-test. However, the lumbar lordosis and strength of gluteus and abdominal muscles in the post-test were not significantly changed compared to the pre-test. Gluteus maximus and abdominis transverse muscle activity rates in the combined group increased significantly in the post-test compared to the pre-test, and gluteus maximus muscle activity rate in the active group increased significantly in the post-test compared to the pre-test. Gluteus maximus muscle activity in the imagery group increased significantly in the post-test compared to the pre-test. The activity of lumbar erector spinae and rectus femoris muscles decreased significantly in the active and combined groups in the post-test compared to the pre-test. However, the activity of the rectus femoris muscle decreased significantly in the image group in the post-test compared to the pre-test (P≤0.05). The results showed a significant difference between the three methods of kinesthetic imagery, active, and combined (P=0.001). There was a significant difference between the method of the imagery exercise and the active and combined exercise methods but no significant difference between methods of the active and combined exercise.
Conclusion: Imagery exercises effectively modified the EMG of some lumbopelvic muscles (gluteus maximus and rectus femoris muscles). However, it had no significant effect on the strength and degree of lumbar lordosis. The combined exercise was as effective as active exercise in modifying the EMG activity of the lumbopelvic muscles and the strength of the abdominal and gluteus maximus muscles.

Abstract
Purpose: Proper posture is essential for maintaining musculoskeletal health. The stability of the spine depends largely on the curvature of the human upright spine, and deviations in sagittal arches may signify a displacement in the body’s center of gravity. This study aims to investigate the relationship between spinal curvature and postural stability to promote optimal spinal health.
Methods: In this cross-sectional study, 120 recreationally active university students (60 men and 60 women) were selected and grouped by gender. Postural stability was assessed using the balance error scoring system (BESS), and the craniovertebral angle (CVA) was evaluated through photographic methods. Kyphosis and lordosis angles were also measured using specific anatomical landmarks. Correlation analyses were performed using Pearson’s and Spearman’s tests, with a statistical significance of P≤0.05, to explore the relationship between the variables
Results: The study’s results showed no significant correlations between thoracic kyphosis, lower back lordosis, and the CVA with BESS scores, except within the male group, where a significant correlation was found between BESS and kyphosis (P=0.01).
Conclusion: This study suggests that evaluating thoracic kyphosis can be crucial to enhance postural stability in recreationally active adults. Further research can investigate interventions aimed at improving postural stability among individuals with kyphosis.
