RESUMO
@#Introduction: Musculoskeletal Disorder (MSD) is an injury that affects the movement of human body systems such as muscles, tendons, ligaments, nerves, blood vessels, and others. The prevalence of MSDs in Indonesia is 11.9% based on diagnosis and 24.7% based on symptoms. MSDs prevalence is 31.2% based on employment among farmers, fishermen, and workers. Methods: The design of this study has been included in observational research using a quantitative approach with Cross-Sectional study. Results: MSDs can appear based on gender, age, educational status, and non-medical supporting professions. Older workers tend to be at risk of developing MSDs complaints. Conclusion: To reduce the risk of complaints, work facilities such as ergonomic chairs and tables can be provided along with extension of work intervals. Workers must take advantage of good rest periods. There is no relationship between work tenure and MSDs complaints. If the working period is long, then it can cause boredom and the endurance of muscles as well as bones physically.
RESUMO
@#Introduction: Musculoskeletal disorders are the most common debilitating causes in workers and the main reason for medical leaves. Medial leave brings health, social, and economic consequences for individuals and society. The relationship between medical leaves due to pain and discomfort in different parts of the body and physical activity level at work, practice of sport, and leisure time in workers in cement industry in 2019 was examined. Methods: A descriptive-analytical study was conducted on 150 workers of a cement factory. The participants were selected randomly. Data gathering tools were demographics form, Nordic Musculoskeletal Questionnaire, and Baecke Physical Activity Questionnaire and the collected data was analyzed using SPSS (v.22). Results: The participants noted that the main painful areas over the past year were the waist, knee, ankle, and neck. There was a significant relationship between medical leave due to pain in the neck and overtime work. There was a significant relationship between the type of work activity and medical leave due to a pain in knee and ankle. Conclusion: The workers who used such medical leaves had a higher PAL at work. PAL at work increased the requests of medical leaves due to the pain in knee and waist. The PAL at sport practice decreased the rate of request for medical leave due to a pain in the Waist and Knee.
RESUMO
Objective To study the characteristics of mouse-desktop and wrist-desktop contact pressure distributions during different mouse operations, and investigate the influence of desktop on the mouse and wrist during mouse operations, so as to obtain biomechanical references for musculoskeletal disorders of the hand and wrist. Methods The laser scanner and TekScan pressure measurement system were employed to measure contact area and contact pressure of the mouse and wrist during different mouse operations. Results The contact pressure, contact area, and contact force varied with time, and the peak contact pressure of the mouse and wrist with desktop were obtained. The peak contact pressure of the mouse in single clicking of left, right key and scrolling of middle key was 62.87, 33.83, 74.66 kPa, respectively, and for the wrist, the minimum contact pressure appeared in key clicking, being 23.25, 11.02, 16.26 kPa, respectively. Conclusions During mouse operations, the thenar, hypothenar as well as the ulnar and radial sides of the wrist are persistently subjected to the continuous pressure, therefore, repetitive and continuous mouse operation can lead to the development of carpal tunnel syndrome of wrist or other MSDs.

RESUMO
Aims: To assess the occupational risk factors that contribute to the occurrence of work- related musculoskeletal disorders among Operation Room (OR) nurses and MSDs relation to biomarker c-telopeptide of type II collagen (CTX-II). Study Design: A cross sectional study. Place and Duration of Study: Cairo University hospitals from January to April 2014. Methodology: The study was conducted upon 184 OR nurses from different specialties. They include 155 females and 29 males with age ranged 20-50 years and work duration ranged 2-35 years. They represent 52.6% of the OR nurses work power all over Cairo University hospitals. The individuals were subjected to questionnaires including Standardized Nordic Questionnaire (SNQ), Job Content Questionnaire (JCQ) and Quick Exposure Check (QEC) for ergonomic risk assessment. Urinary CTX-II was measured. Results: Out of 184 OR nurses, 180 have musculoskeletal symptoms with a prevalence of 97.8%. CTX-II in females was non-statistically significant higher than in males. Higher non-statistically significant levels of CTX-II were found in those aged ≥ 40 years than in those < 40. Non- statistically significant differences were in correlation between CTX-II and various occupational risk factors as BMI, age, duration of employment, physical risk factors except for outreached arm (r= 0.16, p=0.03) and psychosocial factors except for deficient rest break (r=-0.15, p=0.038) which showed statistically significant differences. No statistically significant correlation was found between CTX-II and any of musculoskeletal symptoms during the past twelve months by applying SNQ. A statistically significant difference (Z=2.26, p=0.02) was found in OR nurses group with knee crepitus in comparison with nurses group without knee crepitus among those with high level of urinary CTX-II. Other MSDs showed no statistically significant differences between symptomatizing and non-symptomatizing groups. Conclusion: Operating room nurses are exposed to multiple occupational risk factors leading to MSDs. CTX-II may be a valuable biomarker in early osteoarthritis.
RESUMO
This An Ergonomic hazard often exists in any industry. However, majority of the employees are not aware of practicing good body posture until the MSDs symptoms become permanent and chronic. The main objective of this study is to determine the manual handling problems among workers at an electronic component manufacturing company. The scope of this study focused on the study entire body disorders among workers on electronic manufacturing company using the Rapid Entire Body Assessment (REBA). A cross sectional study involving observation of the workplace, the work task and the working environment, photographs and videos taken during the observation. Later, a survey questionnaire was given to the respondents to obtain their socio-demography information, work activity and health problems. Rapid Entire Body Assessment (REBA) was conducted on all respondents to determined REBA scores in different work positions. The study was conducted at an electronic component manufacturing company located in Klang Valley, Selangor. A total of 124 workers were surveyed and REBA assessment was performed on 20 workers at Company X production area. It includes 5 categories of position at Company X, such as:loading steel bar into casing; pushing the steel bar, turning movement while adjusting the steel bar, adjusting steel bar into the loading area, unloading steel bar from casing into the machine. The study found that turning section has the highest MSDs problems regarding manual handling because majority of the respondents in the turning department felt the pain while performing their work. This is due to their job demand, which they need to handle with tools weighing from 200 to 400 kg. The REBA scores showed that17 out of 20 respondents performing turning operations, moving and pushing the steel bar recorded the highest score of 11 or more which are categorize in the very high risk group. The position of pushing and turning steel bar while moving the steel bar has higher risk that contributed to the ergonomics risk factor, which in-turn can contribute to Muscular Skeletal Disorders (MSDs). More detailed investigation and remedial measures should be taken immediately, especially for the workers performing the manual handlings activities.
