Abstract

Background and Aim: Conventional post-operative rehabilitation programs focus on quadriceps strengthening and knee range of motion. However, hip muscle weakness is evident in patients with knee osteoarthritis. The present trial study aimed to investigate the effects of adding early hip muscle strengthening exercises to conventional rehabilitation programs on pain, Range of Motion (RoM), Quality of Life (QoL), and physical function in patients with unilateral Total Knee Arthroplasty (TKA).
Methods & Materials: The intervention was initiated from the second day after surgery and continued for 10 sessions, 3 times a week on 24 participants in the control and intervention groups. Both research groups received Transcutaneous Electrical Neural Stimulation (TENS) and Infra-Red (IR), followed by exercises. The control group performed knee extensor and flexor strengthening and RoM exercises. The intervention group conducted hip-strengthening exercises in addition. Outcome measures included pain, knee flexion, and extension RoM, and QoL using the 36-Item Short Form Survey (SF-36), Timed Up and Go (TUG) test, Step Test, Six-Minute Walk Test (6MWT), and Hip and Knee Muscle Strength test.
Ethical Considerations: This research was approved by the Research Ethics Committee of Iran University of Medical Sciences (IR.IUMS.REC.1396.9511340012) and it was registered in the Clinical Trial Registration Center (Code: IRCT 20150314021459N6).
Results: All outcome measures improved in both research groups. The improvement in the scores of pain (P=0.03), knee extension RoM (P=0.007), and TUG test (P=0.033) were significantly higher in the intervention group, compared to the control group. The strength of knee flexors (P=0.023), hip flexors (P=0.040), hip extensors (P=0.028), hip adductors (P=0.040), and hip external rotators (P=0.047) significantly improved higher in the intervention group.
Conclusion: According to the present research results, both treatment approaches were effective on patients with unilateral total knee arthroplasty. Considering the better result of some of the outcome measures in the intervention group, the addition of hip strengthening exercises to knee exercises can be useful.

Abstract

Background and Aim Physical activity has multiple health benefits, but its association with fertility in women is still unknown. Considering the critical effects of lifestyle on reproductive health, this study aims to compare the physical activity and body composition of fertile and infertile women.
Methods & Materials This is a case-control study that was performed on 100 fertile and 100 infertile women aged 20-40 years referred to the infertility treatment centers in Arak, Iran. they completed self-reported questionnaires surveying sociodemographic characteristics and lifestyle, and the International Physical Activity Questionnaire (IPAQ) assessing physical activity and sedentary behavior. Anthropometric characteristics and body composition were also measured. Multiple logistic regression analysis was used to analyze the association of fertility with physical activity level, sedentary behavior, and body composition.
Ethical Considerations This study was approved by the Ethics Committee of the University of Arak University of Medical Sciences  (Code: IR.ARAKMU.REC.1400.050).
Results The level of physical activity (P=0.001) was lower and the body mass index (P=0.03) was higher in infertile women than in fertile women. In women with moderate level of physical activity, the risk of infertility was lower (OR=4.42, 95% CI: 1.60-12.99, P=0.004). Women who spent the time sitting for more than 300 minutes a day were 2.07 times more likely to have fertility than women who were physically active (OR=2.07, 95% CI: 1.36-3.14, P=0.001).
Conclusion Low physical activity, sedentary lifestyle and obesity are independent risk factors of infertility. To prevent infertility, more attention should be paid to the lifestyle of women.

Abstract

Introduction: The beneficial effects of physical activity in the treatment of brain-motor disorders of people with autism have received more attention, although the effects of exercise on the evaluation of motor factors (physical fitness) and brain waves have been less studied.
Methods: Eleven children with autism spectrum disorder (7-12 years) took part in the study. After a thorough medical examination and psychiatric assessment, children participated in aquatic exercise program (twice-weekly) for 8 consecutive weeks. Pre & post intervention evaluated base on QEEG (power alpha & coherence), movement assessment (euro fit exam), then stoical analyze are performed (P<0.05). The present research has been registered with the ethics committee of the faculty of sport sciences, Bu-Ali Sina University Hamadan under code IR.UMSHA.REC.1394.107.
Results: In this study, alpha wave absolute power but not coherence in frontal – occipital is significantly increased by8 consecutive weeks’ aquatic program (P<0.05). Physical Fitness assessment parameters (muscular strength/endurance, coordination, balance, flexibility) significantly improved and subside respectively (P<0.05).
Conclusions: These results indicate that aquatic exercise program may improve physical and mental disturbance in young children with autism spectrum disorder.

Abstract

Introduction: Physical activity is one of the important lifestyle factors that can have positive or negative effects on the reproductive system, and more research is needed to reflect the effect of inactivity on fertility in order to provide safe lifestyle recommendations to help couples achieve pregnancy is required. Therefore, this study was conducted with the aim of describing and comparing the physical activity status of fertile and infertile men in Arak city in 2022.
Methods: The present study is a case-control study that was conducted on 220 fertile and infertile men (22 to 40 years old) referred to Arak University Jihad infertility centers that were selected through available sampling. Participants completed self-test questionnaires on socio-demographic characteristics, lifestyle, physical activity, and sedentary behaviors. Anthropometric characteristics and body composition were also measured. Multivariate logistic regression was used to analyze the association of infertility with physical activity level, sedentary behavior, and body composition.
Ethical Considerations: This study was approved by the Ethics Committee of the University of Arak University (Code: IR.ARAKMU.REC.1401.046).
Ethical Considerations: The present research has been registered with the code IR.ARAKU.REC.1401.015 in the Ethics Committee of Arak University.
Results: In this study, it was observed that the amount of physical activity (P=0.02) and body composition (P=0.001) in fertile men is more favorable than infertile men. In men with a low level of physical activity, the risk of infertility increases 2.97 times (odds ratio 2.97 and 95% CI: 1.03, 8.61, and P=0.04). On the other hand, in men with moderate level of physical activity, the risk of infertility decreases (odds ratio 0.27 and 95% CI: 0.08, 0.92, and P=0.03). Also, in men who sit for more than 6 hours a day, the chance of infertility increases by 3.02 times (odds ratio 3.02 and 95% CI: 1.28, 7.10, and P=0.01). An increase in body mass index increases the risk of infertility by 1.61 times in men (odds ratio 1.61 and 95% CI: 1.23 and 2.11 and P=0.001).
Conclusions: Since obesity, physical inactivity and infertility in Iranian men are increasing at the same time, so there should be more focus and seriousness on the issue of lifestyle modification and especially physical activity regarding reproductive health.
