Abstract
Background and Objectives: Nowadays, the use of the Internet among students has become widespread. Addiction to virtual networks and online games can have various consequences, including the threat of musculoskeletal system in these people. The purpose of this study was to determine the effect of addiction to social networks and online games on students’ wrist pain.
Methods: This study was conducted among 665 students. Data collection was done through three questionnaires of problematic use of online games, social networking addiction and Nordic musculoskeletal disorders. Data were compared by Chi-square and independent T-test and finally, logistic regression model was presented at a significant level of 0.05.
Results: The results showed that social network and online game addiction can increase the risk of pain in the wrists. Sex had a significant impact in the effect of social network addiction on pain in the wrist. Other results of the present study are the not significant differences in the age and level of education of the participants in the prevalence of wrist pain.
Conclusion: It can be stated that there is a likelihood of a relationship between social network and online game addiction with wrist pain. Therefore, due to high prevalence of this addiction among students, appropriate planning should be taken to reduce complications and injuries, especially in the wrist area of them.

Abstract
Background and Objectives: Upper extremities are very vulnerable to work-related musculoskeletal disorders and selecting the best technique for assessing their exposure to ergonomic risk factors is of pivotal importance. This study aimed to compare two techniques of SI and ACGIH-HAL and assess their relationship with carpal tunnel syndrome (CTS) among butchers.
Methods: The study population was all butchers in Hamadan, Iran. After observing the activities, the assessments were conducted using both techniques. The severity of CTS syndromes was assessed using Boston questionnaire. The agreement between the techniques was investigated using Kappa coefficient. The association between the risk levels obtained from the techniques with the severity of CTS syndromes were assessed by regression analysis and fixing the effect of personal factors such as age, body mass index, and wrist ratio index.
Results: a total number of 152 butchers were evaluated. SI and ACGIH-HAL techniques respectively recognized 76 and 102 cases as low risk (agreement in 69 cases), 40 and 27 cases as moderate risk (agreement in 8 cases), and 36 and 23 cases as high risk (agreement in 18 cases). The Kappa coefficient between two techniques was 0.36 (P<0.001). By fixing the effects of age, body mass index, and wrist ratio index, both techniques had significant association with the severity of CTS syndromes. However, the association between SI and severity of CTS syndrome was higher than that of ACGIH-HAL.
Conclusion: SI had a higher estimate of risk than ACGIH-HAL. It seems that the predictive ability of SI for the severity of CTS syndrome is better than that of ACGIH-HAL.
