Abstract
Purpose: Neuromuscular and biomechanical factors in ACL injuries are among modifiable risk factors. The purpose of the present study was to evaluate the effect of feedback and feed forward neuromuscular training on balance and isometric strength in female basketball players with a high risk of injury in Kerman.
Method: The present research is semi-experimental, prospective study and the subjects selected objectively based on inclusion and exclusion criteria. Twenty women basketball players of Kerman city purposely selected and who were randomly divided into two groups of feed forward (age=15.73 ±0.78, weigh =61.38±9.09, height = 164.40 ±6.68) and feedback (age=14.70±1.33, weigh =56.31±8.38, height = 161.66±6.02) The training program designed based on the previous studies and conducted during 8 weeks, three sessions per week (each session 15 to 20 minutes) under the supervision of the examiner. Dynamic balance and isometric knee strength was measured using Biodex system and MMT device. One way ANCOVA was used for data analyze.
Result: The results showed significant differences between pre-post test balance Overall Stability index, internal/external index and Anterior/Posterior index (P=0.001).Significant difference was observed in the strength of quadriceps muscle and hamstring muscle between the two groups of feedback and feed forward exercises (P≥0.05). Also, the results of the paired sample t-test showed that Overall Stability in the feedback and feedforward group (0.345% and 0.19%), Balance Anterior/Posterior in the feedback and feedforward group(0.409% and 0.22%) and Balance Medial/Lateral in the feedback and feedforward group(0.427% and 0.22%) has significantly improvement compared to the pre-test (p<0.002).Isometric Quadriceps strength in the post- test showed an significantly improvement of 2.16% in feedback group and 1.82% in feedforward group compared to the pre-test (P=0.001). Isometric hamstring strength in the post- test showed a significantly improvement of 2.07% in feedback group and 1.95% in feedforward group compared to the pre-test (P=0.001).
Conclusion: It can be concluded that neuromuscular training can enhanced balance and isometric strength, of women and training with feedback has more important than training with feedforward.

Abstract
Purpose: Volleyball has a high potential for shoulder dyskinesia due to the repetitive nature of spike, serve and block, so the aim was to investigate electromyography analysis of shoulder girdle muscle in male volleyball players with different types of scapular dyskinesia while performing a floater serve.
Methods: The current research method is the causal-comparative type. 41 volleyball players aged 18-25 were selected non-randomly and purposefully and were divided into three groups (n=13 inferior angle of scapula prominence, n=13 medial border of scapula prominence, n=13 without scapulae dyskinesia). Electromyography of 4 muscles including serratus anterior, upper, middle, and lower trapezius in the dominant shoulder was evaluated while performing a floater serve using MyoMuscle. Data were analyzed using analysis of variance test at the significance level of 0.05.
Results: The results showed that during the acceleration phase of the serving, there was a significant difference in EMG of the upper trapezius (p=0.009) and middle trapezius (p=0.01) between the medial border of scapula prominence group and without dyskinesia group, and there was a significant difference in EMG of serratus anterior (p=0.007) and middle trapezius (p=0.01) between the inferior angle of scapula prominence group and without dyskinesia group.
Conclusion: It seems that during the acceleration phase of the floater serve, volleyball players with medial border of scapula prominence experienced an abnormal increase in upper trapezius activity and inhibition of the middle trapezius activity, while probably volleyball players with inferior angle of scapula prominence experience inhibition the activity of the middle trapezius and serratus anterior.

Abstract
Background and aim: The purpose of this study is to examine how eight weeks of general exercises (GEs) combined with cognitive functional therapy (CFT) affect women with chronic non-specific low back pain (CNSLBP) in terms of pain, quality of life (QoL), and muscle endurance.
Methods: 45 women with CNSLBP participated in this study for eight weeks in three groups: GEs, GEs with CFT, and control. Pain, QoL and muscle endurance were evaluated by visual analogue scale (VAS), SF-36 questionnaire, and Biering-Sorensen test, respectively. Mixed-model repeated measure test with repeated measurement design was used for data analysis.
Results: The results revealed a significant difference in the investigated variables between the pre-test and post-test for the intervention groups, but no difference was seen in the control group.
Discussion and final conclusion: The group of GEs combined with CFT distinguished itself significantly from the group of GEs in the comparison of the factors of physical performance, emotional health, and general health from sub-sections of QoL, and also muscular endurance. According to the results, it is recommended that women with CNSLBP use GEs in combination with CFT to reduce pain, improve QoL, and increase muscle endurance.

Abstract
The purpose of this research was to design and implement a system for the surveillance of sports injuries in students. Sports injuries of male and female high school students in Ilam province were recorded by physical education teachers using online methods and paper forms during one academic semester. At the end, a questionnaire was used to survey them regarding these methods. The research is of a descriptive-comparative type and Chi-square (x2) was used at the significance level (P<0.05) to analyze the results. A total of 151 injuries were reported, of which 76 injuries (50.4 percent) were registered with the online method, 70 injuries (46.3 percent) with the online paper method, and 5 injuries (3.3 percent) with the paper method. Online registration (146 injuries) is significantly more used than paper registration (75 injuries) (p=0.001) physical education teachers give the reasons for using the online method more: availability, easier working with it, and recovery It is easier to record information. On the other hand, they mentioned the interruption and slowness of the internet speed as things that can cause disruption. According to the results, it seems that the use of online methods is more effective in registering sports injuries in schools.

Abstract
Lack of sensory information, muscle weakness, lack of coordination and position sense of joint are predictor factors of musculoskeletal disorders, and it seems that sports activities will have an effect on posture control and joint proprioception. Therefore, the purpose of this research was the effect of Pilates exercises on balance and proprioception in female students. 98 female students between the ages of 18-25 years-old and weight 57.92±7 kg voluntarily participated in this study after completing the written consent form. Of these, 91 healthy students were placed in the experimental group and 7 students with sports exemption (with medical conditions such as: recent surgery for refractive errors of the eye, cysts, etc.) were placed in the control group. The position senses of ankle and knee joints was measured using the active reconstruction test of the ankle and knee angles and static balance was measured using the Sharpened Romberg test before and after 16 intervention sessions. Wilcoxon test was used to determine the difference in pre-test and post-test (intra-group difference) and covariance test was used to compare between groups (of course, the data were normalized earlier). The results showed that after the intervention, in the experimental group, static balance increased significantly in the post-test compared to the pre-test. The position sense of dorsiflexion, plantarflexion of ankle joint and knee flexion position sense in the experimental group increased significantly in the post-test compared to the pre-test. Also, the results of the covariance test showed that there is a significant difference between the two groups in the post-test in the variables of static balance and position sense of dorsiflexion and plantarflexion of ankle and position sense of knee flexion. According to the adjusted average in the post-test stage, the experimental group performed better than the control group. The results showed that Pilates exercises are suitable for improving ankle and knee proprioception and improving postural control in teenagers and young adults.

Abstract
Introduction: Previous studies have shown promising results in improving pain, disability, and kinesiophobia in chronic low back pain patients through pain neuroscience education and targeted cognitive motor control exercises. The aim of this study was to compare the effectiveness of a combination of pain neuroscience education and targeted cognitive motor control exercises with targeted cognitive motor control exercises alone in patients with chronic low back pain.
Materials and Methods: Fifty-four chronic low back pain patients (the pain neuroscience education with targeted cognitive motor control exercises group, n=27 and the targeted cognitive motor control exercises only group, n=27) participated in this study. Pain (visual analogue scale), disability (Oswestry Disability Index), central sensitization inventory, and kinesiophobia (Tampa Scale) were assessed at baseline and eight weeks after interventions. Repeated measures analysis of variance and linear mixed models with Bonferroni correction were used to examine between-group differences.
Results: A significant group × time interaction effect was found for pain (p=0.008), central sensitization inventory (p=0.002) and kinesiophobia (p<0.001) in the pain neuroscience education with targeted cognitive motor control exercises group compared to the targeted cognitive motor control exercises only group after eight weeks. Main effects of time were observed for pain, disability, and fear of movement after interventions (p<0.001). No significant group × time interaction effects was found for disability (p=0.50).
Conclusions: This study’s findings support the provision of pain neuroscience education as a clinically effective addition to targeted cognitive motor control exercises in chronic low back pain patients.

Abstract
Introduction and purpose: Jumping motor tasks in people with motor control defects are probably associated with incomplete movement patterns, which can be related to non-collision injuries of the lower limbs. In relation to these people, it has been recommended that the design of exercise protocols should also be done with the aim of controlling and improving functional defects. Therefore, the aim of the present study is to investigate the eight-week training program of feedback on the biomechanical variables of athletes with selected motor control defects in landing jump tasks.
Materials and methods: The present study is a randomized clinical trial study before and after the intervention. 34 male recreational athletes with movement control defects (dynamic knee valgus and quadriceps dominance) were selected based on the study criteria and then randomly assigned to control groups with a ratio of 1:1 (age range, 28.10±4.70years; height, 171±5.49cm; mass, 76.83±5.81kg; and BMI, 22.12± 1.54kg/m² ) and feedback group (age range, 29.80±3.61years; height, 173.80 ± 4.70cm; mass, 78.33±4.64kg; and BMI, 21.40±1.77 kg/m² ).Electromyography data (vastus medialis, vastus lateralis, gluteus medius, Tensor fasciae latae and biceps femoris) and lower limb kinematics (knee valgus angle) were recorded while the participants performed the landing jump movement tasks (vertical jump, tuck and countermovement) in the two previous stages. From the protocol and after the protocol, they performed jumping exercises for two months. In addition, external feedback (first by using educational videos and then verbally while doing the task (place the knee in line with the toes, press the knee towards the wall (external source)) during the two months of the training program and during Performance of movement tasks was presented to the feedback group. To analyze the data, two-way analysis of variance and Bonferroni statistical tests were used for each movement task at a significance level of P < 0.05.
Findings: The results of the study indicated an increase in the electrical activity of the VM and GM muscles and a decrease in the electrical activity of theVL, BF and TF muscles in different phases of jumping in the feedback group. As an example, the results of the Bonferroni post hoc test showed a significant improvement in the feedback group in the amount of electrical activity of the VM muscle (effect size = 0.57, p = 0.001) and GM(effect size = 0.53, p = 0.002). In the eccentric phase, there was a significant improvement in the amount of electrical activity of the VM muscle (effect size = 1.05, p = 0.001) and GM(effect size = 0.77, p = 0.001) in the maximum knee flexion phase and improvement The electrical activity of VM muscle (effect size = 1.71, p = 0.001) and GM (effect size = 1.19, p = 0.001) had significance in the landing moment phase during vine jump. Also, the feedback group showed a decrease in knee valgus angle in the frontal plane (P < 0.05).
Conclusion: The results of the present study showed that feedback has an effect on kinematic and electromyographic parameters and improves the jump-landing biomechanics of the lower limbs in people with knee motor control defects and can be used to correct incomplete movement patterns in jump-landing tasks. be used However, for a general conclusion, more studies are needed in different groups and different sports levels, as well as more samples.

Abstract
Introduction and aim: Fatigue of injury-prone athletes and their placement in situations such as performing shear maneuvers increases the risk of anterior cruciate ligament injury. Therefore, this research aims to answer the question, does functional fatigue change the effect of neuromuscular training on kinetic variables during cutting in injury-prone male athletes?
Methodology: The current research is semi-experimental and was carried out in two control and experimental groups as a pre-test and post-test design with and without fatigue before and after neuromuscular exercises. 32 males student-athletes aged 18 to 25 with trunk control defects were purposefully selected and randomly placed in the control group (16 people) and the experimental group (16 people). The force plane was used to measure ground reaction forces. Analysis of variance test was used for statistical analysis at a level smaller than P<0.05.
Results: The results of the present study showed a significant improvement in ground reaction force variables in the post-test of the experimental group compared to the pre-test (P<0.05). While none of these variables had significant changes in the control group (P>0.05).
Conclusion: It seems that doing trunk and hip neuromuscular training in athletes with a trunk control defect leads to a significant improvement in the stability of the trunk control, so in the conditions with and without fatigue, they were able to show a significant improvement in the selected parameters of the ground reaction forces. Therefore, this training method can probably be recommended as a beneficial method for athletes and the mentioned conditions

Abstract
Introduction: Balance and proprioception have been introduced as two of the most important internal factors related to the occurrence of injuries in the lower limbs. The purpose of this research is to investigate the changes in static and dynamic balance and proprioceptive accuracy of knee and ankle joints of young taekwondo athletes before and after applying the fatigue protocol.
Methodology: The current research is semi-experimental. The subjects of the research were 20 teenage male taekwondo players from the statistical population. Static and dynamic balance variables were measured respectively by Stork's static balance test and Y dynamic balance test, as well as the proprioception of the ankle and knee joints at 10 degrees of ankle dorsiflexion and 30 degrees of knee flexion, by the photographic method. Then the functional fatigue protocol was applied. After finishing the fatigue protocol, all the variables that were measured before applying the fatigue protocol were evaluated again. In order to examine the intra-group changes of the research variables in the pre- and post-test stages, the paired t-test was used.
Results: The results of the paired t-test showed that after applying the fatigue protocol, there is a significant difference between the average of all the investigated variables in the post-test stage compared to the pre-test.
Conclusion: The results of the present research showed that fatigue can reduce the static and dynamic balance as well as the proprioceptive accuracy of teenage taekwondo athletes. Therefore, it is recommended to all coaches and athletes of this sport, in order to delay the appearance of fatigue and the possibility of injury, to perform specialized training exercises in the field of taekwondo and according to the age of teenagers.

Abstract
Wrestling is a high contact sport with a significant risk of injuries. Identifying risk factors can help preventing wrestler’s injuries. little is known about the contribution of balance and proprioception to sport injuries. The purpose of this study was to find out the relationship between dynamic balance and knee proprioception and the injuries in young wrestler.72 young wrestlers from Tehran primer league participated in this study. Before the start of season, proprioception was measured at 30°, 60° and 90° knee flexion using the Biodex Isokinetic pro 4 system. Dynamic balance was measured by Biodex balance system. Injuries were recorded by the team's medical staff. Logistic regression modeling indicated that there is no significant relation between Dynamic balance and proprioception of knee at 30 and 60 and at 90 degree and musculoskeletal injuries. Balance and proprioception testing, as performed in the present study, cannot be recommended as a screening test to predict injuries in young male wrestler.

Abstract
Considering the prevalence of pain and disability in the knee joint, the present study investigated the effect of core stability training with improving knee joint proprioception on balance, pain and functional disability of women with chronic knee pain. 20 women aged 30 to 50 with chronic knee pain were placed in two experimental and control groups. To measure static and dynamic balance, pain and functional disability, the stork balance tests, Y, VAS and VOMACK questionnaire were used, respectively. Exercises were followed for eight weeks in the experimental group. To evaluate the research hypotheses, the analysis of variance test with repeated measurements was used in spss software version 24. The results showed that before the exercise protocol, there was no significant difference between the control and experimental groups in any of the measured variables. While the eight-week training protocol caused a significant difference in static and dynamic balance, functional disability and pain between the control and experimental groups. Therefore, core stability training with improving knee joint proprioception increase balance in people with chronic knee pain, which can reduce the risk of falling in these people and improve the quality of life by improving pain and functional disability.

Abstract
Functional Movement Screen Test is one of the tests used to identify asymmetries and limitations in basic and fundamental movements. For time management and fast execution of this test, some researchers have suggested reducing the number of tests. The purpose of the present study was to investigate the internal consistency and correlation between components of this test. The present study was a correlational study. In this study, movement screen test was performed on 165 male and female students aged 18 to 25 years of Shahid Beheshti University using a special FMS kit. Results: The internal consistency of the test, measured by Cronbach's alpha method, was acceptable (α=0.71). The results of multivariate regression test showed that there was a low to medium correlation between the internal components of the test, but a high correlation was observed between the test components and the final FMS score. The results also showed a high correlation between the "four small movements" (Active leg raising, shoulder mobility, stability push up and rotary stability) and the total FMS score and a low correlation between the "three big movements" and the FMS score. Motor function screen test is a valid tool for evaluating motor performance. The results also show that in large communities such as students, and if there is a time limit, "four small movements" can be used instead of seven.
