It has more prevalence and severity in women than in men. The aim of this research was to compare the navicular drop (ND) and hallux deviation (HD) in women with different knee osteoarthritis (OA) based on the radiographic grades of 1 to 4. Instruments and Methods: The present research was a descriptive cross-sectional and causal-comparative study. The study population included women with knee osteoarthritis in Tehran. The statistical sample included 87 female patients with knee osteoarthritis, who were selected based on the simple purposive and non-probability sampling method from patients referring to specialized clinics and Akhtar Hospital in 2015. The number of knees with knee OA was 168, which were divided into 4 groups based on the Kellgren-Lawrence grading scale. One-way analysis of variance was used to compare the difference between the groups in terms of the amount of navicular drop and the hallux deviation, and for significant results, Tukey's post hoc test was applied. Findings: There was a significant difference between the first and second groups regarding the extent of ND, which was mostly observed in Group 2. It was non-significantly higher in Group 4 in comparison with Group 3 and higher in Group 3 than in Group 1. The mean of HD increased from Group 1 to 4 but not significantly. Conclusion: Higher drop in navicular is a risk factor for the development of knee osteoarthritis radiographic grades.

Fouladi Dehaghi ‎Occupational Health Department, Public Health Faculty, Ahvaz Jundishapur University of Medical Sciences, ‎Ahvaz, Iran J. Tamaddon Yalameh‎ ‎Occupational Health Department, Student Research Committee, Gonabad University of Medical Sciences, ‎Gonabad, Iran Journal Article 1970 01 01 Aims: In developing countries such as our country, most of the activities such as carpentry is performed manually and make workers exposure to inappropriate postures, which will increase the prevalence of Musculoskeletal Disorders (MSDs). One way to reduce these disorders is educational ergonomics interventions. The present study aimed at determining the effect of education on reducing ergonomic risk in traditional carpet weavers working in workshops in Golestan province, Iran. Materials & Methods: This quasi-experimental study was conducted on 100 employees in 54 traditional workshops in Golestan province of Iran in 2016. The studied population consisted of horsewomen carpet weavers who had at least one-year work experience and were selected based on simple random sampling method. The QEC method was used to assess the risk of musculoskeletal disorders and Nordic standard questionnaire was used to determine the frequency of symptoms of these disorders. The data were analyzed by SPSS 19, using paired sample t-test and Wilcoxon. Findings: In the pre-interventional stage, the greatest risk was related to the neck (71.0%) at high-risk level. This intervention was significantly reduced from interventional, and only 5.0% of subjects were at this level (p<0.001). The waist circumference was 97.0% of the subjects before the training at the level of intermediate exposure. After intervention, this amount decreased and most of the subjects (64%) were exposed to low levels of exposure. Conclusion: Education can reduce ergonomic risk in traditional carpet weavers working in workshops.
