Volume 4, Issue 2 (10-2016)
Abstract

Introduction: According to the effectiveness and low cost of prevention, ergonomic assessment methods as a means to predict the potential occurrence of injury are being used. The aim of the present research was the assessment of validity and reliability of researcher-made ergonomic assessment test for freestyle wrestling skills.

Methods: In this research, according to the jobs ergonomic evaluation tests and wrestling pathology research, an ergonomic evaluation test for wrestling skills (WSEAtest) was designed. Content and face validity were proved by using the opinions of sports biomechanics and pathology experts, as well as physicians, physiotherapists, trainers and wrestlers of Freestyle national team. Furthermore, the test was performed on three skills in two different days by five examiners, using Kinovea software 0.8.15; also, intra- and inter-tester reliability were calculated. After the reliability and validity approval, WSEAtest was performed on video records of four selected skills of Iranian freestyle wrestlers in London 2012 Olympic games.

Results: The injury exposure in various parts of body, traumatic factors related to collisions and loads, and athlete and environment conditions were consistent with wrestling pathological research and confirmed the validity of the test results.

Conclusions: WSEAtest has acceptable validity and reliability; trainers, specialists, and sports therapists can use this test to assess traumatic factors and identify priorities for training and corrective exercises in different wrestling levels, and in various ages.

Abstract
Objectives: Musculoskeletal disorders (MSDs) are among the most common occupational health problems, particularly prevalent in driving-related professions. This study aimed to assess body posture and the risk of developing MSDs among urban train operators in Mashhad using the Rapid Entire Body Assessment (REBA) method.
Methods: In this cross-sectional study, 140 train operators from the Mashhad Urban Railway were randomly selected. Demographic information and the prevalence of MSDs were collected using the Nordic Musculoskeletal Questionnaire, and postural assessment was performed using the REBA method. Statistical analysis was conducted using parametric (independent samples t-test) and non-parametric (chi-square) tests.
Results: A total of 87.1% of participants reported musculoskeletal complaints in at least one body region. The most commonly affected areas were the neck (60%), lower back (57.1%), and upper back (33.6%). REBA results indicated that 71.4% of operators were in the medium-risk category. There was a significant association between musculoskeletal disorders and body mass index (BMI), as well as years of work experience (p<0.05).
Conclusion: Given the high prevalence of MSDs and the medium level of postural risk among train operators, ergonomic interventions and training on proper working posture are strongly recommended to improve occupational health in this group.
