Purpose: The Identification of Functional Ankle Instability (IdFAI) questionnaire is a valid and reliable tool to identify ankle instability, but this questionnaire is written in English and Persian speakers have difficulties in using it. Therefore, this study aimed to translate the IdFAI questionnaire in Persian and evaluate its validity and reliability.
Methods: The present study is a non-experimental, analytical, and descriptive study. After translating the IdFAI questionnaire with a standard policy, it was given to 100 individuals with a history of at least 1 ankle sprain and 45 participants who had no history of an ankle sprain. The Cumberland Ankle Instability Tool (CAIT) was also distributed to the participants to examine the validity of IdFAI. After 1 week, a questionnaire was distributed among several participants to determine the repeatability of the test-retest of the Persian version of the questionnaire. After collecting the data, intraclass correlation, the Standard Error of Measurement (SEM), and the Cronbach alpha coefficient of the questionnaire were calculated in SPSS version 20.
Results: The correlation of the IdFAI questionnaire with the CAIT was 0.71. The Cronbach alpha coefficient of 0.88 showed an acceptable level for the reliability of the questionnaire. Also, the correlation coefficient of the test-retest was 0.95, indicating a high degree of repeatability of the Persian version of the questionnaire. The SEM was 2.35, and the factor analysis showed that the questionnaire’s items could be classified into three categories, with a maximum of 72.5% variance coverage.
Conclusion: The Persian version of the IdFAI questionnaire has excellent reliability and validity in identifying Persian-speaking participants with functional ankle instability. This questionnaire can be used for people with ankle sprain injuries in future studies, clinical examinations, and evaluations.

Background: A thoracic curve degree of greater than 45° leads to thoracic hyperkyphosis, and its common treatment method is orthotic treatment. The acceptance rate of spinal orthosis depends on in-brace correction, patient`s compliance and quality of life.
Objective: In this study, we aimed to compare in-brace correction, compliance and quality of life in patients with thoracic hyperkyphosis wearing Milwaukee and Lyon braces.
Methods: In this case study, we retrospectively analyzed data for 23 adolescents with thoracic hyperkyphosis worn Milwaukee brace (n=15) and Lyon brace (n=8). In-brace correction was assessed by comparing Cobb angle before and two months after wearing brace. Compliance was determined by the percentage of actual hours worn in accordance with the prescribed regimen. The Quality of Life Profile for Spinal Deformities questionnaire was used to assess the quality of life and mental/psychological functions. Data normality assumption was assessed by Kolmogorov-Smirnov test. Other tests used for data analysis included paired t-test and independent t-test.
Results: Patients had thoracic kyphosis angle of 55-75 degrees aged 10-17 years. They were divided into two groups of Milwaukee(n=15; mean age= 14 years; mean first Cobb angle= 67.9 degrees) and Lyon (n=8; mean age= 13.75 years ; mean first Cobb angle= 61.7 degrees). No significant difference was found between in-brace correction of two groups (p= 0.073), while the compliance of Lyon group was better. Furthermore, findings reported a significant difference in quality of life between groups (p= 0.018), where Lyon group had improved quality of life.
Conclusion: Lyon brace had less detrimental effect on the quality of life of patients in comparison with the Milwaukee brace, while the compliance after using Lyon brace was better; however, identical in-brace correction was achieved by both braces. Therefore, by considering and integration of significant factors in treatment plan, these braces can be used for in-brace correction.

Purpose: Intensive military training courses are among the programs and specialties of the police force. Musculoskeletal disorders in the military are one of the vital factors that keep people away from courses and shorten their service life. This research aims to measure the prevalence of musculoskeletal injuries in newly arrived students in the pre-service training course of the police force using the Oslo Sports Trauma Research Center (OSTRC) questionnaire.
Methods: For this purpose, 124 soldiers with a mean age of 20.7 years, a mean height of 178.5 cm, a mean weight of 72.9 kg, and a mean activity per week for 3 hours and 19 minutes in one of the training barracks affiliated to the Tehran Police Force and were selected and completed the OSTRC questionnaire every month for 6 months. The research design of this study is epidemiology and the results are presented descriptively.
Results: The results of the research related to prevalence measurement on a monthly mean showed that ankles at 2.8%, knees at 2.2%, and waist at 1.8% respectively have the highest prevalence rates among soldiers. Also, among the harmful factors, the parade had the largest share with 22.5% and during 6 months, the second month had the highest number of injuries, and the sixth month had the lowest number of injuries. In terms of participation in exercises, 86.6% of soldiers participated in practical classes without any physical injuries during the six months. A total of 9.1% of the soldiers could not perform optimally and properly despite their full attendance in the practical classes due to physical injuries and finally, 3.8% of the participants, despite attending the practical classes, had to leave the class halfway due to the severity of the injury.
Conclusion: What is clear is that the most affected areas are the central area and the lower limbs, and the spine of the back, head, neck, and upper limbs were not among the most damaged areas. Finally, it seems that the prevalence rate among the soldiers in training courses is acceptable and close to the average of global statistics. However, it is required to take preventive measures as well as plan to add classes and specialized exercises to strengthen physical fitness and specialized exercises related to improving the conditions of damaged areas.
