Resultados. El promedio de edad fue de 31 años. El 54 % de la población tiene sobrepeso, lleva en promedio 4,7 años en la labor y trabaja en promedio 70 horas semanales. La zona con mayor prevalencia de molestias es la espalda baja, con el 76 %. Del total de casos, el 48 % presentó molestias en más de un segmento corporal y el 37 % en solo una zona del cuerpo, el 85 % de la población reportó al menos un síntoma musculoesquelético. Conclusión. La región de la espalda baja presentó mayor sintomatología con el 76 %, seguido de los hombros y el cuello. La región que menos síntomas reportaron los trabajadores es a nivel de codos.
Objective: To determine the prevalence of musculoskeletal symptoms in logistics operators of a Santander shipping company. Materials and method: Descriptive cross-sectional study, with the participation of 67 male workers. The self-report of musculoskeletal symptoms was analyzed with the Standardized Nordic Questionnaire. Results: The average age was 31 years. 54% of the population is overweight, they have been working on average 4.7 years and work an average of 70 hours per week. The area with the highest prevalence of discomfort is the lower back, with 76%. Of all cases, 48% presented discomfort in more than one body segment and 37% in only one area of the body. 85% of the population reported, at least, one musculoskeletal symptom. Conclusion: The lower back region presented the most symptoms with 76%, followed by the shoulders and neck. The region with the least symptoms reported by workers is at the elbow level.
ABSTRACT
The manual handling of people (MHP) is known to be associated with high incidence of musculoskeletal disorders for aged care staff. Environment-related MHP interventions, such as appropriate seated heights to aid sit-to-stand transfers, can reduce staff injury while improving the patient's mobility. Promoting patient mobility within the manual handling interaction is an endorsed MHP risk control intervention strategy. This article provides a narrative review of the types of MHP environmental controls that can improve mobility, as well as the extent to which these environmental controls are considered in MHP risk management and assessment tools. Although a range of possible environmental interventions exist, current tools only consider these in a limited manner. Development of an assessment tool that more comprehensively covers environmental strategies in MHP risk management could help reduce staff injury and improve resident mobility through auditing existing practices and guiding the design of new and refurbished aged care facilities.

The purpose of this review is to name and describe the important factors of musculoskeletal strain originating from pushing and pulling tasks such as cart handling that are commonly found in industrial contexts. A literature database search was performed using the research platform Web of Science. For a study to be included in this review differences in measured or calculated strain had to be investigated with regard to: (1) cart weight/ load; (2) handle position and design; (3) exerted forces; (4) handling task (push and pull); or (5) task experience. Thirteen studies met the inclusion criteria and proved to be of adequate methodological quality by the standards of the Alberta Heritage Foundation for Medical Research. External load or cart weight proved to be the most influential factor of strain. The ideal handle positions ranged from hip to shoulder height and were dependent on the strain factor that was focused on as well as the handling task. Furthermore, task experience and subsequently handling technique were also key to reducing strain. Workplace settings that regularly involve pushing and pulling should be checked for potential improvements with regards to lower weight of the loaded handling device, handle design, and good practice guidelines to further reduce musculoskeletal disease prevalence.

Oil palm workers are exposed to ergonomics problems in their routine works. Although many technological advances have been developed, a large number of workers are still using manual handling tools in their daily work. A study was done to identify and solve the problems or issues of material handling effect on oil palm collectors and loaders during their daily work activities. A cross sectional study was done in an oil palm plantation in Negeri Sembilan, Malaysia. Twenty five workers were selected randomly to participate in this study. Musculoskeletal symptoms were recorded using Modified Nordic Questionnaires and awkward postures of the workers were assessed using Rapid Entire Body Assessment (REBA). Result showed that 61% of workers were exposed to high risk level and 39% to very high risk level of working posture problems. In conclusion, majority of oil palm collectors and loaders need to correct their working posture as soon as possible. The manual handling activities need to be improved with respect to correct procedure for health and safety concerns.
ABSTRACT
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.
ABSTRACT
Objective To evaluate the application effect of UK manual moving & handling skills in the training of preventing occupational lower back pain among nursing professionals,and explore effective ways of training on preventing occupational lower back pain to nursing professionals.Methods 86 nursing students,94 nurses with 12 months' work experience,and 88 nurses with work experience over 5 years were randomized selected,and they each were divided into the experimental group and the control group.For 86 nursing students,43 students in each group; For 94 nurses with 12 months' work experience,47 nurses in each group; For 88 nurses with work experience over 5 years,44 nurses in each group.A routine taught training was given to both groups,while the experimental group received an extra 25 academic hours' structured OLBP prevention training.Comprehensive proposition was used to assess theoretic learning outcome of all participants,and practical skills of all participants were tested through institutional cases.Ressults There was significant statistical difference between scores of participants from two groups,and the scores of the experimental group in nurses with 12 months' work experience were different from the experimental groups of nursing students and nurses with work experience over 5 years.Conclusions Structured OLBP prevention training should lead occupational health prevention and health promotion concepts,apply numerous teaching approaches,emphasize the content of maintaining physical and psychiatric health and occupational protection management,set new-enrolled nurses as the main focused group of training.
