While most of the existing literatures regarding female athletes' LBP have focused on particular sports with specific low back demands (such as skiing and rowing), many other sports have not been studied very well in this regard. Investigating LBP prevalence and related factors in other types of sports, such as combat sports, badminton and shooting, can help us better understand the prevalence of low back pain and provide us with necessary insight to take effective steps towards its prevention in athletes.
Aim The COVID-19 pandemic is a global health emergency, and therefore the prevention and treatment of this disease is an important priority of world health. In the present study, some risk factors, including unhealthy nutrition, obesity, and physical inactivity, were assessed in patients infected with SARS-CoV-2, and their effects on the severity and duration of disease were evaluated. Subject and methods The present study was a cross-sectional study. Data was collected from all patients who visited the respiratory emergency department from March 20, 2020 to April 24, 2020 in the University Hospital. The outcome measures were body mass index, diet quality that was evaluated with a 16-item food intake questionnaire, and physical activity level that was assessed by the global physical activity questionnaire. Results Two hundred and six patients' data was analyzed. The results investigated that patients with lower levels of physical activity or lower MET.min/week were affected by a more severe form of the disease (p = 0.05 and p = 0.03, respectively). We found that patients with a healthier dietary pattern were affected by lower severity of illness (p < 0.05). Conclusion It seems that increasing levels of physical activity may partly reduce the severity of COVID-19 disease. Some dietary patterns such as increasing fruit and poultry consumption as well as drinking less tea were correlated significantly with a less severe form of the disease. The results did not confirm previous concerns regarding a potentially harmful effect of smoking on the severity or duration of symptoms.
Study DesignSingle-blinded randomized controlled trial.PurposeTo evaluate the effects of a multi-step core stability exercise program in nurses with chronic low back pain (CLBP).Overview of LiteratureCLBP is a common disorder among nurses. Considering that patient-handling activities predispose nurses to CLBP, core stability exercises suggested for managing CLBP in the general population may also be helpful in nurses. However, sufficient evidence is not available on whether a multi-step core stability exercise program affects pain, disability, quality of life, and the diameter of lateral abdominal muscles in nurses with CLBP.MethodsIn this single-blinded randomized controlled trial, 36 female nurses with CLBP were recruited. The sample was divided into two groups of 18 patients (intervention and control). Nurses in the intervention group performed core stability exercises for 8 weeks, based on a progressive pattern over time. Roland–Morris Disability Questionnaire (RDQ), quality of life (36-item Short Form Health Survey [SF-36]), ultrasound assessment of the diameter of lateral abdominal muscles, and Visual Analog Scale (VAS) score for pain were evaluated in the participants before and after the trial. Sixteen nurses (eight from each group) dropped out of the study, and analysis of covariance was used to compare outcomes for the remaining nurses in the intervention (10 nurses) and control (10 nurses) groups.ResultsThe results after the trial showed significant improvements in RDQ, SF-36, and VAS score in the intervention group compared with that in the control group (p <0.005). Furthermore, the ultrasound data showed a significant increase in the left and right muscle diameter of all three abdominal muscles during the abdominal drawing-in maneuver in the intervention group compared with that in the control group (p <0.05).Conclusions This study showed that a multi-step core stability exercise program is a helpful treatment option for improving quality of life and reducing disability and pain in female nurses with CLBP.
This is the first study investigating the prevalence of CNP, CLBP, and CKP in the national population of Iran. It shows some modifiable risk factors for CMP, and suggests that affordable planning for these risk factors can be valuable in preventing CMP globally. However, this is a cross-sectional study and future longitudinal studies in this field are necessary.
There are many proposed core stability exercises in a variety of positions; however, it is not clear that in which position, activation of transverse abdominis muscle is utmost. We aimed to compare the activation of transverse abdominis muscle in different core stability exercise positions through ultrasound imaging. in a 20 subjects' study we compared the effectiveness of drawing-in and bracing maneuvers on transverse abdominis in different core stability exercise positions (supine, hook lying, supine with 90° flexed knee and hip, supine with stretched knees and 90° flexed hips, bridge, bridge with one stretched knee and Bird dog). We used activation ratio and preferential activation ratio as measurements of transverse abdominis activation. Abdominal Bracing in the bridge position showed the highest activation of transverse abdominis (P< 0.05). The results showed significantly higher activation of transverse abdominis, measured by preferential activation ratio, in bridge position during abdominal bracing.
To assess the prevalence and correlates of low physical activity among Iranian population aged 15-64 years. We used the data collected in National Surveillance of Risk Factors of Non-Communicable Diseases in Iran, 2011. Physical activity was categorized in 3 levels of low, moderate, and high based on a Persian version of Global Physical Activity Questionnaire. The multistage cluster sampling design was accounted for using complex survey analysis method. The sample included 10016 individuals; 41.7% (n = 4178) were men and 58.3% (n = 5837) were women. The mean (SD) age of participants was 38.8 (14.9) years also, and 69.8% (n = 6991) of the participants were from urban areas. The prevalence of low physical activity in the whole population was estimated to be 44.8% (95% CI: 41.7, 48.1). The odds of lower physical activity in the women were 3 times greater than men (OR = 3.14; 95% CI: 2.64, 3.57); in the wealthiest people was 25% lower than the poorest people (OR = 0.75; 95% CI: 0.60, 0.94). The odds of lower physical activity in the age groups 55-64 years were 44% greater than the youngest age groups 15-24 years (OR = 1.44; 95% CI: 1.23, 1.68). The odds of lower physical activity in the obese participants were 18% greater than normal-weight people (OR = 1.18; 95% CI: 1.01, 1.38).). The odds of lower physical activity in diabetic patients were 30% greater than healthy people (OR: 1.30; 95% CI: 1.07, 1.57). The prevalence of low physical activity in Iran, 2011 was high. The correlates of low physical activity in Iran are different to those of Western populations. The main associated factors with low physical activity were female gender, urban area, low socioeconomic status, obesity, diabetes, and older age. Public health policies should target the groups at highest risk of low physical activity.
BackgroundLow back pain (LBP) is a common complaint amongst adolescent athletes. While different studies have shown association between LBP and trunk muscle thickness in the general population, few articles have studied it in adolescent athletes.ObjectivesThe aim of this study is to compare lateral abdominal muscle thickness and function, and cross sectional area (CSA) of lumbar multifidus (LM) in adolescent soccer players with and without LBP.MethodsIn total, 28 adolescent soccer players with and without LBP, from the premier league participated in this study. The thickness of external oblique, internal oblique and transversus abdominis and the CSA of the LM muscles at L4 level on both sides were measured at rest and contraction via ultrasound imaging (USI). In addition, leg length discrepancy, hamstring flexibility, active lumbar forward flexion, and isometric muscle endurance of trunk extensors were measured in both groups. (study design/setting: case control study).ResultsThe mean (SD) age in LBP group and non-LBP group were 14.0 (1.1) and 14.1 (0.9) years, respectively. There was no significant difference in baseline characteristics of participants between groups. Findings showed no significant difference between LBP and non-LBP groups comparing all measured variables.ConclusionsThe data obtained support that there is not a correlation between abdominal muscle thickness and CSA of the lumbar multifidi and LBP in adolescent soccer players. These findings suggest that other factors rather than the thickness of deep trunk muscles may play a more significant role in the etiology of LBP in adolescent soccer players.
