    Musculoskeletal complaints are generally felt a lot because of the habits done during work. Body posture when working improperly and maintained in a relatively long time can lead to musculoskeletal complaints. Working in a sitting position for a relatively long period of time with a bent and bent body position can be a risk factor for complaints of neck pain or back pain. This study aims to analyze the relationship between long-standing work posture with subjective complaints of neck pain in leather craft industry workers in Selosari. The study design was an observational analytic study with a cross sectional approach. The sampling technique in this study was proportional random sampling with a sample of 42 respondents from the leather craft industry workers in Selosari. The results of statistical analysis with the Chi Square test showed that p=0.006 (p <0.05), which means there is a relationship between the length of maintaining work posture to subjective complaints of neck pain in leather craft industry workers in Selosari. It should be noted that prolonged retention of neck posture which is too bent when working continuously for long periods of time will increase the risk of neck pain complaints. So it is necessary to improve the posture of the body when working, especially the neck or movement or changes in posture, especially the neck if it starts feeling stiff or stiff in the neck

    BACKGROUND: The lack of clear understanding of the association between sitting posture and adolescent musculoskeletal pain, might reflect invalid and/or unreliable posture measurement instruments. The psychometric properties of any new measurement instrument should be demonstrated prior to use for research or clinical purposes. This paper describes psychometric testing of a new three-dimensional (3D), portable, non-invasive posture analysis tool (3D-PAT), from sequential studies using a mannequin and high school students. METHODS: The first study compared the 3D-(X-, Y- and Z-) coordinates of reflective markers placed on a mannequin using the 3D-PAT, and the Vicon motion analysis system. This study also tested the reliability of taking repeated measures of the 3D-coordinates of the reflective markers. The second study determined the concurrent validity and test-retest reliability of the 3D-PAT measurements of nine sitting postural angles of high school students undertaking a standard computing task. In both studies, concordance correlation coefficients and Intraclass correlation coefficients described test-retest reliability, whilst Pearson product moment correlation coefficients and Bland-Altman plots demonstrated concurrent validity. RESULTS: The 3D-PAT provides reliable and valid 3D measurements of five of the nine postural angles i.e. head flexion, neck flexion, cranio-cervical angle, trunk flexion and head lateral bending in adolescents undertaking a standard task. CONCLUSIONS: The 3D-PAT is appropriate for research and clinical settings to measure five upper quadrant postural angles in three dimensions. As a measurement instrument it can provide further understanding of the relationship between sitting posture, changes to sitting posture and adolescent musculoskeletal pain.Web of Scienc

    [Purpose] To investigate the prevalence of neck and shoulder symptoms during the use of tablet computer, and to identify the risk factors associated with these symptoms. [Subjects and Methods] A cross-sectional survey was conducted to study tablet computer usage, posture during use, and neck and shoulder symptoms in 412 participants in a school setting. Significant risk factors for musculoskeletal symptoms during tablet computer use were identified. [Results] Overall prevalence of musculoskeletal symptoms during tablet computer use was 67.9% with greater prevalence of neck symptoms (neck: 84.6%; shoulder/upper extremity: 65.4%). Significant risk factors associated with symptoms during use were: current musculoskeletal symptoms, gender, roles, and postural factors including: sitting without back support, sitting with device in lap, and lying on the side and on the back during tablet computer use. A multivariate analysis further showed that the odds for females to have symptoms were 2.059 times higher than males. [Conclusion] The findings revealed that female gender and other postural factors were significantly associated with musculoskeletal symptoms during the use of tablet computer. Among all postural factors, sitting without back support was identified as the most important risk factor for having musculoskeletal symptom

    WORK-RELATED MUSCULOSKELETAL DISORDERS AMONG DENTISTS AND ORTHODONTISTS A thesis submitted in partial fulfillment of the requirements for the degree of Master of Science in Dentistry at Virginia Commonwealth University. by Natalie R. La Rochelle Thesis Director: Dr. Eser Tüfekçi, D.D.S., M.S., Ph.D., M.S.H.A. Professor, Department of Orthodontics Virginia Commonwealth University Richmond, Virginia May 2017 The practice of dentistry is physically demanding due to static and dynamic postures sustained daily throughout careers. Previous literature suggests that work-related musculoskeletal disorders (WMSD) are not solely the result of work habits, but also due to the individual, his or her physical makeup, genetics, and personal lifestyle. A 33-question survey was distributed to 1000 general dentists and 2300 orthodontists. The overall prevalence of work-related musculoskeletal disorders was greater among dentists and most often reported as self-limiting. Dentists were three times more likely than orthodontists to report WMSD; females were twice as likely to report WMSD than males; those who sought alternative medical remedies were two times more likely to have WMSD; and practitioners 6-10 years in practice were least likely to report WMSD. Dentists reported sitting in static positions longer than orthodontists; and those with WMSD indicated exercising, stretching, and seeking alternative health remedies more than dentists without WMSD

    National hazard exposure worker surveillance: exposure to biomechanical demands, pain and fatigue symptoms and the provision of controls in Australian workplaces

    Get PDF
    Biomechanical demands such as repetitive hand or arm movements, lifting heavy loads or working in awkward postures contribute to the development or worsening of inflammatory or degenerative musculoskeletal disorders. However, little is known about patterns of exposure to different biomechanical demands and how they relate to the demographic and employment characteristics of Australian workers. To address this, in 2008 the National Hazard Exposure Worker Surveillance [NHEWS] survey collected information on 4500 Australian workers’ exposure to nine biomechanical demands, pain and fatigue symptoms and the provision of various risk controls. Almost all workers reported some level of exposure to the biomechanical demands surveyed and 22 per cent were deemed to have high overall (composite) biomechanical demand exposure. In particular, young workers, male workers, night workers and lower skilled workers were most likely to report exposure and had the highest overall biomechanical demand exposure. The reporting of pain and fatigue symptoms was highly related to the level of biomechanical demand exposure. Workplace size (number of workers at a site) and the overall level of biomechanical demand exposure were the best predictors of control provision: workers from large workplaces and those with high exposure were most likely to be provided with biomechanical demand controls. This report presents detailed findings of the NHEWS survey and discusses the implications of these findings for work health and safety policy

    Health and safety at work directly influence the development of sustainable agriculture. In the agricultural sector, many farm workers suffer musculoskeletal disorders caused by forced posture. The objective of this research is to assess working postures during melon cultivation in Almería-type greenhouses. The Ovako Working Posture Assessment System (OWAS) has been used with pictures of the tasks. The variables studied by multiple correspondence analysis were as follows: Subtask, Posture code, Back, Arms, Legs, Load, Risk, and Risk combination. The OWAS analysis showed that 47.57% of the postures were assessed as risk category 2, 14.32% as risk category 3, 0.47% as risk category 4, and the rest as risk category 1. Corrective measures should be implemented immediately, as soon as possible, or in the near future, depending on the risks detected

    to investigate the prevalence of back pain during a prior three-month period; to identify postural and behavioral habits; to assess whether a relationship exists between back pain and the postural and behavioral habits of elementary school students in the municipal school network in the city of Teutônia, Rio Grande do Sul (RS). METHODS: this was an epidemiological population study in which 833 5th to 8th grade students from schools in the municipal school network in Teutônia participated. The students completed a Back Pain and Body Posture Evaluation Instrument (BackPEI) questionnaire that assessed back pain and postural and behavioral habits. The analysis was performed using descriptive statistics, calculating prevalence ratios (PR) and confidence intervals at the 95% level. The dependent variable was back pain, and the independent variables were postural and behavioral habits. The PR was calculated using a multivariate analysis with robust variance (α = 0.05). RESULTS: the prevalence of back pain in the previous three months was 54.1%. The majority of students reported feeling pain once per month, and 17.4% of the students reported that pain impaired their performance of daily activities. The multivariate analysis showed a correlation between back pain and time spent per day watching television (p = 0.046), sleeping posture (p = 0.048) and sitting Down to write (p = 0.032). CONCLUSIONS: these results demonstrate a high prevalence of back pain in schoolchildren, suggesting an urgent need to develop educational and preventative programs in schools
