Methods: The present study was semi–experimental. The statistical population was all primary and secondary school students from the 4th to 8th grades who participated in the movement correctional centers of Karaj (Alborz province, north of Iran), including 752 people. The statistical sample of the study consisted of 45 boys 10 to 14 years old with non–structural scoliosis with curvature less than 20 degrees, which were identified by random sampling into three groups of 15 experimental subjects (2 groups of SEAS and Evminov exercises) and a control group. Inclusion criteria included 1) 10 to 14 years old boys with non–structural scoliosis with lateral curvature of less than 20 degrees; 2) non–use of other therapies for treatment; 3) lack of employment for specific work or regular exercise. Exclusion criteria included 1) had any pathological symptoms, history of fractures, surgery or joint diseases in the spine, shoulder and shoulder belt; 2) regular weekly physical activity, membership in sports teams, and lack of completion of a training program based on the goals of the research or the lack of interest of the subject; 3) structural or functional shortness of more than 2 centimeters in one of the lower limbs 4) scoliosis convulsion or structural and protic scoliosis, including spinal rotation and apparent deformities of the trunk during the Adams test in forward folded forward position 5) weight outside normal range or BMI less than 18 or more It was 25. The research tools included the standard Evminov board, the EOS700D digital camera, and the corresponding tripod, digital astronomy, digital scale for the subjects' weight, Corel Draw 110, and a small and large training platform ladder. The training program for SEAS and Evminov was for 12 weeks and three sessions per week. In the Evminov training group, each move with 3 to 5 repetitions between 10 to 12 seconds and the rest of 12 to 15 seconds and a 10 to 20 gradient degree Evminov board. In the SEAS training group, six different types of exercises ranged from 10 to 12 seconds and three to five repetitions with a rest time of 12 to 15 seconds. The Kolmogorov–Smirnov test used for normality investigation, data analysis, and t–test and ANOVA test and LSD post hoc test used for data analysis. Also, the statistical significance of 95% confidence level with alpha less than or equal to 0.05 considered at all stages of the test. After data collection, using SPSS software version 24, the results were interpreted.
Results: The results of this study showed that 12 weeks of Seas and Evminov exercises had a significant effect on the malformation of nonstructural scoliosis in boys aged 10 to 14 years (p≤0.001). In addition, there was no significant difference between the results of SEAS and Evminov exercises on nonstructural scoliosis abnormalities.
Conclusion: It seems that corrective exercises, especially exercises based on the principles of SEAS and Evminov practices, can be effective in reducing the angle of lateral deviation of the spine, and it is suggested that further research be conducted to increase the external validity of the study.

Methods: The research was semi–experimental and the research design was a pretest–posttest with the experimental and control group. The statistical population of the study consisted of women aged 18 to 45 years old who referred to the Baneh city (Kurdistan province, Iran) school of rehabilitation. In this study, 30 women with mild and moderate toes (15 to 30 degrees) with a mean and standard deviation of age: 30.83±8.26, 161.63±4.41, 61.77±5.47, the target group was selected and randomly divided into two groups: training–bandages and control group. First, the angle of the shoulder was determined using radiographs. The training group–bonding for 8 weeks and 24 hours with Kinesio tape and daily two repetitive exercises of the thumb. The control group did not receive intervention. After 8 weeks, radiography was performed using the angle of hallux valgus. The training group –Bondage used a Kinesio tape for 8 weeks and 24 hours, and twice–daily exercises were performed on the hallux valgus, while the control group did not receive the intervention. The exercises include seven exercises, which should be performed for 8 weeks and twice daily. Between each repetition, 5 seconds rest and each move are restrained for 20 seconds. Experimental group exercises included mobility, stretching, tensile strength, strength, tensile strength, strength, strength, strength in each session. When exercising, the subjects were asked to use the muscles of the shoulder and to prevent the creation and production of force by the muscles of the wrists or legs. The angle of hallux valgus was measured in both groups at the beginning and end of the eighth week by radiography. Independent t–test (intra–group comparison) and independent t–test (inter–group comparison) were used to compare the results at 95% significance level and the alpha value smaller or equal to 0.05. Data were analyzed using SPSS version 22 software.
Results: The results showed that there was a significant difference between the pre–test and post–test scales angle in the training group (p<0.001). However, there was no difference between the scores of pre–test and post–test of angle of thumb in the control group. In addition, the difference in post–test scores between test–band and control group was significant (p<0.001). In other words, the combined exercise–bandage program can reduce the angle of the thumb.
Conclusion: It seems that in order to correct hallux valgus in women, we can use the training program–bandage program. Results showed that practicing lumbar spine could have a positive effect on the improvement of angles and in women with hallux valgus.

Methods: This was a quasi–experimental study with a pretest–posttest and a control group design. This research was performed on 30 adolescents with scoliosis. The mean±SD age of the study subjects was 14.85±3.73 years; their mean±SD Body Mass Index (BMI) equaled 20.41±1.34 kg/m2, and their mean±SD Cobb angle was measured as 16.54±2.12 degree. The inclusion criteria of the study included having triangular thoracic scoliosis, having a thoracic arch angle of 10–20 degrees respecting the scale of Cobb angle and the radiograph in the patients’ medical records, and an age range of 12–18 years. The exclusion criteria of the study were non–participation in two consecutive training sessions and three non–consecutive sessions, the lack of proper cooperation, pain, and dissatisfaction to continue research. The 8–week training program of the intervention group was considered as an independent variable. The step length, i.e., measured using video recording by a camera, was considered as a dependent variable. For investigating differences between the control and intervention groups, we used the Independent Samples t–test. Besides, the differences between pretest and posttest stages were examined applying Dependent Samples t–test at the significance level of 0.05 in SPSS.
Results: The results of the Dependent Samples t–test revealed a significant difference between the pretest and posttest values of the intervention group (p=0.001); however, there was no significant difference between the pretest and posttest values of the control group (p=0.106). The results of the Independent Samples t–test suggested a significant difference between the control and intervention groups (p=0.002). The stride length of the intervention group has increased by 8.3 cm. The effectiveness of this intervention on Cohen’s D scale was calculated as 1.66, indicating the high efficacy of this exercise intervention.
Conclusion: According to the present study data, there was an increase of about 8.3 cm in the stride length of the study subjects. Thus, Schroth corrective exercise significantly impacted the stride length of adolescents with triple–curve thoracic idiopathic scoliotic.

Background & Objectives: Musculoskeletal disorders are the main cause of occupational or work–related diseases. Occupational illnesses and especially chronic non–specific low back pain account for the majority of musculoskeletal disorders and cause long–term physical conditions and related treatments for the affected person. These individuals may even leave their jobs due to pain and illness. So this condition is very important. These diseases, due to their physiology, cause numerous problems, like pain and imbalance in the affected patients, resulting in increased healthcare costs and declined quality of life. Therapeutic exercise interventions in people with chronic non–specific back pain can be effective to a great extent, and for this purpose, various exercise programs have been proposed. However, some contradictory results are also observed in previous research investigating the effect of core stability exercises on patients with chronic low back pain. Accordingly, the present study aimed to investigate the effect of a stable weekly exercise program on static and dynamic balance in patients with chronic non–specific low back pain.
Methods: The present quasi–experimental study was conducted on 40 medical staff with low back pain working at Shariati Hospital in Isfahan City, Iran. The study subjects were randomly divided into two groups of control and intervention (each group of 20 subjects). The control group performed the routine exercises and the intervention group performed the stability training for 8 weeks. Before and after the intervention, the static and dynamic balance of the patients was measured by the Balance Error Scoring System (BESS) and Star Balance Test. In the BESS, the static balance of each subject on two stable and unstable surfaces was assessed. Moreover, they were evaluated in three physical states, including a standing position on two legs, standing on one leg with 90–degree knee flexion, and the tandem stance with non–dominant foot behind dominant foot in heel–toe fashion, with closed eyes and hands on hips. Additionally, each situation was preserved for 20 seconds. The subject receive 1 negative score for each of these mistakes: opening the eyes, removing the hands from the hips, laying the foot at the time of standing on one leg on the ground, stepping leakage or any movement of the legs, lifting the toe or heel, a flexion or abduction of>30 degrees in the pelvis, and staying>5 seconds. Also, a standard RA was recorded in the off–state. The star test (dynamic balance) was performed 8 times for each subject in 8 directions, as follows: anterior, anterolateral, anteromedial, posterior, medial, posteromedial, posterolateral and lateral. In this test, 8 directions with a 45–degree angle were drawn as a star on the ground. Before initiating the test, the dominant leg of the study subject was determined; if the right leg were dominant, the test would have been performed in the clockwise direction, and if the left leg were dominant, the test would have been performed in a counterclockwise direction. The obtained data were analyzed by the t–test, Chi–squared test, Wilcoxon test, and Mann–Whitney U test at a significance level of 0.05 in SPSS version 23 software.
Results: The results showed that, in the examination of dynamic balance, in the core stability group, significant progress was made in the anterior (p=0.001), anteromedial (p=0.001), medial (p<0.001), posteromedial (p=0.001), posterior (p<0.001), posterolateral (p<0.001), lateral (p<0.001), anterolateral (p<0.001) and the combination of eight directions (p=0.011), after eight weeks of general exercises. However, in the control group, no significant improvement was observed in the anterior, anteromedial, medial, posteromedial, posterior, posterolateral, and lateral before and after eight weeks of general exercises (p>0.05). Nevertheless, there was a significant decrease in anterolateral direction (p=0.016). In the analysis of static balance, in the core stability group, a significant improvement was achieved in different situations of unstable level (p=0.001) and stable level (p=0.008). However, no significant progress was observed for the control group in different situations of unstable level and stable levels (p>0.05).
Conclusion: Based on the present study’s findings, the core stability training intervention affected the static and dynamic balance of medical personnel suffering from chronic non–specific back pain and improved the physical performance of these patients.

Background & Objectives: Being prone to Low Back Pain (LBP) development is a concept in the field of back pain prevention. Those prone to develop LBP show differences in motor control patterns compared to those who are not. Therefore, the present study aimed to compare postural sway and duration of the stance phase of gait between 18-30 years old men prone to LBP and non-prone to LBP.
Methods: The current study was observational and comparative. The statistical population comprised all the students living in the University of Tehran dormitory. Of whom, 33 individuals were selected purposefully based on inclusion and exclusion criteria. The inclusion criteria were as follows: being 18-30 years old men; having body mass index of 18-30 kg/m2; not working in a job in the last 12 months that required prolonged standing, lacking apparent musculoskeletal disorders in the trunk, upper and lower limbs; lacking any visual, vestibular, nervous, muscular, or pain problems affecting the balance; lacking LBP that causes any of the following outcomes: receiving medical interventions, absence of work for more than 3 days, and surgery in the waist, pelvis, and lower limbs. The exclusion criteria were as follows: report of low back pain at the beginning of long standing protocol, not able to complete the study questionnaire, score more than 13 in the Baecke physical activity questionnaire, score more than 13 in Borg scale (almost heavy work), and reluctant to finish the test. The study participants were divided into two groups: prone to develop low back pain (16 patients) and non-prone to develop LBP (17 patients) by performing active hip abduction test and reporting their pain based on the visual analog scale during the prolonged standing protocol. Postural sway and duration of the stance phase of gait were measured using the Biodex balance system and Foot Medisense device. Data analysis was done using the independent t test and Mann-Whitney U test in SPSS version 28 software, at a significance level of α=0.05.
Results: The results showed no significant difference between the prone to LBP group and the non-prone group regarding the anterior-posterior stability index, the medial-lateral stability index, and the overall stability index( in both static and dynamic positions for all indexes) and duration of the stance phase of gait between low back pain developers and non-pain developers.
Conclusion: It seems that people prone to develop LBP do not experience any changes in postural sway and duration of stance phase of gait before the onset of low back pain, and these variables may not be able to help identify those who are prone to develop low back pain.

Abstract
Background & Objectives: Ankle injury is one of the most common sports and daily life injuries. Usually, in 15%–60% of cases, Functional Ankle Instability (FAI) occurs after the initial sprain of the ankle. People with FAI have different muscle recruitment patterns and neuromuscular firing rates than healthy people. The human body relies on three sensory systems to maintain balance: vision, somatosensory, and vestibular. Information obtained from weight can be united by all three systems in the central nervous system, and balance can be established. Virtual reality technology is a new way to create more visual impairment and instability. By providing unreal visual cues, virtual reality makes the central nervous system rely on somatosensory and vestibular to maintain balance. This study aims to investigate the electromyographic activity of selected lower limb muscles in feedback and feedforward phases with and without using virtual reality in male badminton players with and without FAI.
Methods: The current research method was quasi–experimental. The statistical population of this research comprised Badminton athletes aged 15 to 18 who were playing at the professional level. Thirty Badminton players were divided into two groups with and without ankle instability, and each group included 15 subjects. The Cumberland Ankle Instability Tool (Hiller et al., 2006) was used to diagnose FAI. The group with FAI received a Cumberland questionnaire score of 0 to 27, and the control group received a score of 27 to 30. The Anterior Drawer of the Ankle Test was performed to ensure the absence of mechanical instability, and if the participants showed mechanical instability, they were excluded from the research. Motion Lab System MA400 (DTU) device was used to measure the electrical activity of muscles, and the F–RG model electrode was made by Skintact. The electromyographic activity of the tibialis anterior, peroneus longus, and lateral gastrocnemius muscles in the feedforward and feedback phases was studied using virtual reality. After checking the normality of the data, the independent t test and Man–Whitney U test were used to analyze the data at a significance level of 0.05 using SPSS 27.
Results: The independent t test and Man–Whitney U test results showed a significant difference in the feedforward and feedback phases between the groups with FAI and without FAI regarding the tibialis anterior, peroneus longus muscles activities (p<0.05). When using Virtual Reality in the feedforward phase, there is a significant difference between the tibialis anterior (p=0.003) and lateral gastrocnemius muscles (p<0.001) in the group with and without FAI when using virtual reality. It should be noted that the activity of the tibialis anterior and lateral gastrocnemius muscle in the group without functional instability of the ankle in the feedforward phase was higher than the group with FAI. Also, a significant difference was observed in the feedback phase in the tibialis anterior (p=0.006) and the lateral gastrocnemius muscle (p<0.001) between the group with and without ankle functional instability. It should be noted that the activity of the tibialis anterior and lateral gastrocnemius muscle in the group without ankle functional instability in the feedback phase was higher than in the group with ankle functional instability. Also, there is no significant difference between the FAI and non–FAI groups regarding peroneus longus.
Conclusion: According to the results, virtual reality can change the electromyography activity of the ankle muscles. There are changes in the electromyographic activity of the tibialis anterior and lateral gastrocnemius muscle when using virtual reality between athletes with and without FAI, indicating the effect of virtual reality on the electromyographic activity of ankle muscles in these people.
