The aim of this study was to compare the EMG activity of selected muscles around the ankle joint of those athletes with ankle dorsiflexion range of motion limitation with healthy Athletes during the single-leg jump landing. Materials and Methods : Fifteen male athletes with ankle dorsiflexion range of motion limitations were categorized as the group with limitation and the same number of male athletes without limitation in ankle dorsiflexion range of motion as the healthy group. Universal goniometer was used to measure range of motion of the ankle. EMG activity of selected muscles of the ankle during single-leg jump landing task was recorded. A multivariate analysis of variance was used to compare the EMG activity of the muscles between groups. The significance level for all analyses ...

Method and Materials: Twenty-four subjects developing transient LBP during prolonged standing (9males, 15females) between 17-85 years of age, were examined by 2 corrective exercise specialists. In order to control the effect of repeated testing on intra-rater reliability, both raters assessed the subjects at the same time. To assess inter-rater reliability, one of the raters assessed the subjects one week later. Examination findings were recorded independently, without discussion. Inter-and intra-rater reliability were indexed by the percent of agreement and kappa coefficient. Findings: Overall, the kappa values for intra-and inter-rater reliability of the items ranged from 0.12-0.86 and 62.5-1.00, respectively. Conclusion: The results of the present study indicate these clinical test items as a reliable tool for corrective exercise specialists. They can reliably utilize these test items for identification of movement and alignment impairments that need to be modified in order to prevent the onset of LBP in in healthy-back PDs.

Methods: To evaluate the validity of spinal mouse device in measuring angle values of thoracic kyphosis and lumbar lordosis, 20 subjects who referred to one of the Imaging Centers of Tehran to get full spine radiography in profile view according to prescription of specialist physician, were selected. Input and output indexes were assessed and measurements were performed by two methods in one day and no spaces. Finally, angles in the X-ray method with Cobb way and in the mouse spinal with results recorded on the screen, were compared with the Pearson correlation coefficient.To assess Intera-tester reliability 30 male students of University of Theran were randomly assigned included into the research so that measurements in three times in three consecutive days, As well as for Inter-tester reliability 15 male students of University of Tehran in two time with an interval of one minute were measured by two examiners. The result were analyzed using Intraclass Correlation Coefficient. Results: Results of Pearson correlation coefficient test showed that the spinal mouse device has desirable validity in measuring angle values of thoracic kyphosis (r=0.81, P=0.001) and lumbar lordosis (r=0.86, P=0.001) compared with radiography image. Also Intera-tester reliability and Inter-tester reliability of spinal mouse device was desirable for measuring angle values of thoracic kyphosis (ICC=0.92, ICC=0.79) and lumbar lordosis (ICC=0.89, ICC=0.87). Conclusion: spinal mouse device as a non-invasive safe device and a proper substitute for radiography image for measuring angle values of thoracic kyphosis and lumbar lordosis.

After Primary screening and identification of eligible athletes with ankle joint functional assessment tool (AJFAT), subjects were divided into the experimental (n=15) and control group (n =15). Athletes' experimental group did two types of core stability exercises in a session. Postural sway measured in both groups before and after the test. Results: Statistical test results showed that the core stability exercises affected the postural sway in athletes with functional ankle instability in the short-term with the closed eyes and significantly reduced their postural sway (p˂0/05). But this exercises had no effect on postural sway with open eyes (p<0/05). Conclusion: It seems that core stabilizer muscles are important in control of proximal and distal joints for reduction of postural sway in athletes with functional ankle instability when their eyes are closed and doing this exercises in the short-term can be useful in reduction of postural sway in athletes with functional ankle instability.

This cohort discussed the effect of the number of dissected LNs on the prognosis [survival, disease-free survival (DFS)] of patients with stage II and III CRC. Methods: In this historical prospective cohort study, the records of 946 patients with CRC operated in the Seyyed-Al-Shohada hospital in Isfahan from 1998 to 2014 were enrolled. Then the impact of LNs on the overall survival (OS) and DFS were analyzed. Results: The number of removed LNs was higher among males [mean difference = 1.38, t (944) = 2.232, P-value = 0.02]. The median of the DFS for the patients with 1 to 20 LN removal was 104 months [95% confidence interval (CI): 90.97-117.03], while this number for the patients with more than 20 nodes was 166 months (95% CI: 140.41-191.58). DFS between two groups of CRCs, LN removal 1-20, and greater than 20. Age and number of LN removal were significant predictors of the DFS. There was a strong and statistically significant correlation between DFS and OS among CRC patients. Conclusions: This study shows that if the number of resected LNs in patients with CRC is more than 20, it will increase in DFS and OS.

Clinical observations have suggested that hamstring tightness influences the lumbar pelvic rhythm and may be associated with modifications in the sagittal spine curvatures during trunk flexion. Moreover, there is still no agreement on the best stretching techniques. Therefore, the aim of the present study was to compare the effect of six weeks of active and inactive static training on lumbar-pelvic rhythm in forward flexion in men with hamstring shortness. Methods This study was a quasi-experimental study with pre-test and post-test with two groups. In this study, 26 men with hamstring shortness, with a Mean±SD age of 25.76±1.71 years were selected (via purposeful sampling). Hamstring muscle shortness was measured utilizing the SLR and 90-90SLR tests. Measurements of the lumbar pelvic rhythm were recorded in the three-phase forward bending by a spinal mouse. Variables included pelvic rotation and lumbar flexion. Active and passive static stretching were respectively jack-knife and kneeling hamstring stretching techniques. To compare pre-test and post-test values of active and passive static stretching groups, the paired t-test and Wilcoxon test were utilized. Furthermore, to assess the difference between active and passive static stretching groups, the ANCOVA and Mann-Whitney U test were utilized. Results After six weeks of active and passive static stretching, the total pelvic rotation significantly increased in contrast to total lumbar flexion (P<0/05). A comparison of pelvic and lumbar ROM output did not reveal a significant difference between active and passive static groups (P>0/05). Conclusion Compliant with the findings, active and passive static stretching could change the lumbopelvic rhythm to a pelvic-dominant motion, indicating that a flexible hamstring is important for preventing low back pain and other problems associated with the disturbance of the lumbo-lumbar rhythm.

Thus, efficient training programs should be accomplished to decrease injury risk and improve performance. Objectives: Given the necessity of developing injury prevention approaches in programming the training, this study aimed at investigating the effect of an Injury Prevention Program on Traumatic Factors and Athletic Performance in junior Judokas. Methods: 46 subjects were randomly classified into 2 groups of experimental (N: 23) and control (N: 23) groups. For eight weeks, the experimental group attended a specific Judo functional training program designed by the researchers. The control group participated in the usual judo training program presented by the coaches. The exercises were accomplished 3 times per week for 90 minutes each session. The subjects participated in pre-and post-tests. To approve the data normality and compare the variables, Shapiro-wilk, ANCOVA analysis was implemented at the significant level of p˂ 0.05 using SPSS (version 21). Results: The outcomes showed that the scores of functional movement screening (p = 0.001), upper extremity Y balance test (p = 0.001), vertical jump (p = 0.001), and special judo fitness test (p = 0.001) significantly increased among the experimental group. Conclusions: This intervention can modify or decreases the injury risk factors and improves athletic performance and offers more efficiency and effectiveness rather than the common judo training programs.
