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.

Abstract
The aim of this research was effect of eight weeks of neuromuscular training (NMT) with and without cognitive-dual tasks (DTs) on proprioception and balance of athletes with ACL deficiency (ACL-D). 39 soccer players with ACL-D were selected purposefully and randomly divided into three groups of 13 (control group, neuromuscular training group and neuromuscular training with dual tasks group). Two training groups performed the exercises for eight weeks and three sessions per week. cognitive-motor dual tasks were performed in one of the groups along with neuromuscular exercises in the form of counting down numbers, memorizing numbers, calculating unexpected equations, specialized football skill movements. The results of the current study indicated that there was no significant difference in knee joint proprioception in the open and closed kinetic chain after applying the intervention between the three groups, but there was a significant difference in lower extremity performance of the athletes based on the Y balance test in the anterior and posterior-lateral direction between the three groups (p<0.05). It seems that providing neuromuscular exercises along with cognitive-dual tasks can probably be considered as a useful approach to improve lower extremity performance based on the Y balance test in athletes with anterior cruciate ligament deficiency.

Abstract
Purpose: Volleyball has a high potential for shoulder dyskinesia due to the repetitive nature of it’s movements, 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 were selected non-randomly and purposefully and were divided into three groups (n=13 Pattern I, n=13 Pattern II, n=13 without scapulae dyskinesia). Electromyography of serratus anterior, upper, middle, and lower trapezius was evaluated while performing a floater serve using MyoMuscle.
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 pattern II and no-dyskinesia, and there was a significant difference in EMG of serratus anterior (p=0.007) and middle trapezius (p=0.01) between the pattern I and no-dyskinesia,
Conclusion: It seems that during the acceleration phase, volleyball players with pattern II experienced an abnormal increase in upper trapezius activity and inhibition of the middle trapezius activity, while probably volleyball players with pattern I experience inhibition the activity of the middle trapezius and serratus anterior.

Abstract
Purpose: Today, many new exercises are offered to strengthen central stability muscles, and CXWORX exercises are one of them. The purpose of this study was to investigate the effect of CXWORX exercises on postural and functional stability, proprioception, strength and specific skill in basketball players with trunk defects.
Methods: The current research was a semi-experimental and applied type of research. 30 female basketball players with trunk defects were selected by available sampling and randomly placed in two groups. Trunk defects were evaluated through the tuck jump test, lower limb stability through the Flamingo test, functional stability of the upper limb and dynamic balance through the Y test. CXWORX exercises were performed for six weeks by the training group. dependent t-tests and covariance analysis were used to analyze the data.
Results: The results showed that six weeks CXWORX exercises have a significant effect on improving the stability of upper limb function (P<0.05), dynamic and static balance (P<0.05) and specific skill (P<0.05) in basketball players with trunk defects.
Conclusion: Based on the findings of the present study, it is recommended that health and corrective exercise professionals utilize CXWORX training to enhance the sports efficiency, sports performance, and sport-specific skill of basketball players.

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
Introduction: The aim of this study was to compare the effectiveness of a combination of pain neuroscience education and targeted cognitive motor control training with targeted cognitive motor control training alone in patients with chronic low back pain.
Materials and Methods: Fifty-four chronic low back pain patients (pain neuroscience education with targeted cognitive motor control training group, n=27 and targeted cognitive motor control training only group, n=27) participated in this study. Pain, disability, central sensitization inventory, and kinesiophobia were assessed at baseline and eight weeks after interventions. Repeated measures analysis of variance and linear mixed models 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 training group compared to the targeted cognitive motor control training 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 training in chronic low back pain patients.
