“…The exposed group comprised 184 hair salon employees in 6 districts of Pusan city, and the non-exposed group comprised 119 individuals living in the same areas. They reported that the prevalence of musculoskeletal symptoms among Korean hairdressers was 59.9% in the neck, 76.6% in shoulders, 41.2%upper back, 72.2% lower back, 31.3% arm and elbow, 44.2% wrist, 35.0% finger, and 71.1% in legs (24). According to the study by Hokm Abadi, the prevalence of disorders in different parts of the body was as follows: 8% in the wrist, 20% the neck, 36% shoulders, 46% back, and 84% in the legs (25).…”

Received: December 2014, Accepted: April 2015 Background: Work-related musculoskeletal disorders (WRMSDs) are considered a major factor in health problems, human injuries, and loss of work time. The aim of the present study was to assess the risk of musculoskeletal disorder (MSD) and evaluate the prevalence of MSD among female hairdressers. Materials and Methods: In this descriptive analytical study, the risk of MSDs was evaluated in 172 female hairdressers using the Rapid Entire Body Assessment (REBA) method. Moreover, the prevalence of WRMSDs was investigated using a Nordic questionnaire. All obtained data was analyzed by means of SPSS software, and the logistic regression model. Results:The results showed that 58.7% of the hairdressers experienced pain in their lower back, 52.3% in their neck, 41.3% in their knees, and 20.3% in their ankle. The results of this study showed a significant correlation between BMI and MSDs in the elbow, hip, and thigh. The results of REBA indicate that about 46% of the 1032 postures were classified as high risk and about 14.9% as very high risk. In addition, the results of this study showed a significant correlation between REBA score and MSDs in the neck, wrist, hip, and thigh. Conclusions: With regard to the high prevalence of symptoms in the waist, neck, and wrist, it can be concluded that prolonged standing, uncomfortable working postures, strenuous movements, excessive shoulder flexion and shoulder abduction, trunk flexion and forceful exertion, and repetitive motion are considered important risk factors for MSDs.

| Background: The handling of materials, which occurs in the industrial sector, is associated with lesions on the lumbar spine and in the upper limbs. Inserting handles in industrial boxes is a way to reduce work-related risks. Although the position and angle of the handles are significant factors in comfort and safety during handling, these factors have rarely been studied objectively. Objective: To compare the handling of a commercial box and prototypes with handles and to evaluate the effects on upper limb posture, muscle electrical activity, and perceived acceptability using different grips while handling materials from different heights. Method: Thirty-seven healthy volunteers evaluated the handles of prototypes that allowed for changes in position (top and bottom) and angle (0°, 15°, and 30°). Wrist, elbow, and shoulder movements were evaluated using electrogoniometry and inclinometry. The muscle electrical activity in the wrist extensors, biceps brachii, and the upper portion of the trapezius was measured using a portable electromyographer. The recorded data on muscle movements and electrical activity were synchronized. Subjective evaluations of acceptability were evaluated using a visual analog scale. Results and Conclusions: The prototypes with handles at a 30° angle produced the highest acceptability ratings, more neutral wrist positions, lower levels of electromyographic activity for the upper trapezius, and lower elevation angles for the arms. The different measurement methods were complementary in evaluating the upper limbs during handling.Keywords: ergonomic design; usability; electrogoniometry; electromyography; grip perception.

“…While these studies address some of the general hazards of the tattoo industry, one area that has thus far not been researched is the ergonomic risks that tattoo artists face on a daily basis. Indeed, tattoo artists face many of the same risks that occupations such as dentistry and cosmetology face, and while the ergonomic risks of these professions have been well-covered (e.g., Åkesson, Balogh, and Hansson, 2012;Chen, Chang, Liu, and Chen, 2010;Thornton, L.J., StuartButtle, C., Eyszynski, T.C., and Wilson, 2004), no attention has been given to the similar risks faced by tattoo artists.…”

Despite the widespread popularity of tattoos in the U.S. and worldwide, little consideration has been given to the occupational risk factors that tattoo artists face. Tattoo artists are exposed to many of the same risk factors faced by occupations such as dentistry and cosmetology, including prolonged static work postures and sustained gripping of hand held tools. However, no research has evaluated the extent to which the tattooing profession is adversely affected by its occupational demands. Utilizing a survey of tattoo artists, this research sought to benchmark the prevalence of symptoms commonly associated with the development of musculoskeletal disorders. The survey results revealed that tattoo artists experience high levels of discomfort in the lower back, neck, shoulders, and upper extremities and that these levels significantly exceed discomfort reported in professions that expose workers to similar ergonomic risk factors.
