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
Aim and Background: Ankle is one of the most common sports injuries caused by direct collisions with opposing players or the ground, tackles from inside and outside, jumping and landing. Among these injuries, external ankle sprain is one of the most common injuries that is associated with ankle instability. The purpose of this research is to compare balance exercises and hopping on the proprioception of athletes with functional ankle instability.
Materials and methods: 30 athletes with functional instability of the ankle were randomly divided into 2 study groups of the clinical trial. The first group included athletes with functional ankle instability doing hopping exercises (15 people), the second group included athletes with functional ankle instability doing balance exercises (15 people). At first, the proprioception of their ankle joint was evaluated with the help of photography, and then they did exercises for 6 weeks, and at the end, the proprioception of the ankle joint was evaluated again. SPSS version 20 software was used to analyze the data of this research.
Results: The results showed that balance and hopping exercises significantly reduced the absolute error of ankle dorsiflexion and plantarflexion reconstruction (p<0.05). Also, there is a significant difference between the two groups of balance exercises and hopping (p<0.05).
Conclusion: The results of the present study showed that balance and hopping exercises improved the proprioception of the ankle joint in athletes with functional instability of the ankle, and hopping exercises are more effective than balance exercises.

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
The most common side effect of physical activity is the risk of musculoskeletal damage, that anterior cruciate ligament injury is the most common one. Purpose of the study is comparing the effect of six weeks of comprehensive injury prevention training on anterior cruciate ligament with internal and external feedback on the proprioception and knee function of active female university students. Forty five active female university students aged 18-25 years were volunteered and randomly assigned to three groups (internal, external and control) and they performed the protocol three times a week for six weeks. Proprioception and function of the knee joint were measured using goniometer and functional tests in two stages namely pre-test and post-test. Statistical analysis of covariance, paired t test and Tukey's post hoc tests were used for statistical analysis with a significant level of p≤0.05. Overall results of the study showed that the present exercise protocol with internal and external feedback had a significant effect on the proprioception of p≤0.001 and p=0.000 for the knee performance and there was no significant difference between the two training groups. Regarding the results of the study, it is suggested that the present training protocol be addressed by coaches and sport sciences specialists as a complementary tool and method, along with other training methods, for those who are prone to damage to the anterior cruciate ligament.

Abstract
Although to improve balance and grasp the proprioception, recommended balance exercises, but there is not clear mechanism for the effectiveness of equilibrium training on healthy subjects. Suitable interaction of varios system of body and environment are necessary to maintain of the balance. Balance exercise is prescribed to improve balance and proprioception. There is not clear mechanism about the effectiveness of these exercise on healthy subjects. So The purpose of this study was to the Effect of 8 weeks of ankle-specific balance training on the balance and knee and ankle proprioception of adolescent volleyball players. the statistical sample of this study was 30 adolescent volleyball players in the league Golestan Which were selected as accessible and were randomly assigned into experimental and control groups. The experimental group performed 8 weeks and 3 sessions per week of ankle-specific balance. The results showed that there was a significant difference in the mean of balance and errors in reconstructing the angles of knee and ankle after exercise in the experimental group, while in the control group it was not significant. Results of this study showed that Balance Training can improve balance and proprioception in the knee and the ankle.

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
Upper-crossed syndrome is one of the most common disorders of the upper body, which is associated with 45-65% of shoulder pain. This study has been conducted to investigate the effect of corrective exercises focused on chain reactions, on scapular position, proprioception and shoulder functional stability of female students with UCS. 30 female students between 14 and 18 years of age in Urmia city who had the mentioned disorder were selected using the purposive sampling method and were randomly divided into two experimental groups (15 people) and control (15 people). A tape measure was used to evaluate the distance between the median of the sternum to the coracoid ridge and the posterior-lateral distance of the acromion to the thoracic vertebra (scapular position), the Layton flexometer to measure proprioception, the Y Balance Test to evaluate the function of the upper limb, and the goniometer, tape measure and flexible ruler, respectively were used to measure head and shoulder forward angle and kyphosis. Independent and dependent t-tests were used to compare inter-group and intra-group means, respectively. The present study showed that the effect of corrective exercises on scapular position, proprioception and shoulder functional stability of female students with UCS was significant.
