Opis:
The objectives of this study were to examine the agreement between 5 ergonomic risk assessment methods calculated on the basis of quantitative exposure measures and to examine the ability of the methods to correctly classify 4 at risk jobs. Surface electromyography and electrogoniometry were used to record the physical exposures of 87 sawmill workers performing 4 repetitive jobs. Five ergonomic risk assessment tools (rapid upper limb assessment [RULA], rapid entire body assessment [REBA], American conference of governmental industrial hygienist’s threshold limit value for mono-task hand work [ACGIH TLV], strain index [SI], and concise exposure index [OCRA]) were calculated. Dichotomization of risk to no risk and at risk resulted in high agreement between methods. Percentage of perfect agreement between methods when 3 levels of risk were considered was moderate and varied by job. Of the methods examined, the RULA and SI were best (correct classification rates of 99 and 97% respectively). The quantitative ACGIH-TLV for mono-task hand work and Borg scale were worst (misclassification rates of 86 and 28% respectively).

Opis:
BackgroundPhysical therapists are known to be susceptible to work-related musculoskeletal disorders (WMSDs), but the prevalence of WMSDs in Saudi Arabia has not been documented. This study aimed to establish the prevalence, characteristics, and risk factors of WMSDs among physical therapists in Saudi Arabia.Material and MethodsA cross-sectional study was conducted among 113 physical therapists in Saudi Arabia using a 6-component questionnaire. Descriptive statistics, incidence, percentages, and χ2 test were used for data analysis.ResultsThe response rate was 68.8%. The reported 12-month incidence of WMSDs was 83.8%. The low back (63.7%) was the most common site of these disorders, followed by the neck (59.2%), while the hip/thigh (4.4%) was the least involved body part. Incidence was related to gender: females were more affected than males (neck, shoulders, low back); age: younger therapists were more affected than older ones (shoulders, low back); working sector: government sector workers were more affected than those employed in other sectors (neck); and specialty: orthopedic specialists were the most frequently affected, followed by those specializing in neurology (thumbs, upper back, knees, ankle/foot). Most of the physical therapists had >5 periods of neck, shoulder, and low-back WMSDs. The most important risk factor for WMSDs was treating more patients in a day (47.7%). The most frequently adopted handling strategy identified to combat WMSDS was modifying the patient’s position (62.8%).ConclusionsOverall, WMSDs among physical therapists in Saudi Arabia are common, with the low back and the neck constituting the most frequently affected body regions. Professional experience and the awareness of ergonomics principles can help prevent the early development of WMSDs among physical therapists. Med Pr. 2021;72(4):363–73

Opis:
Objectives. The present study sought to identify firefighters’ rated physical demands for the most frequently occurring work tasks and to determine if the ratings differed between full-time and part-time firefighters to help create a basis for the development of physical employment tests for firefighters. Methods. An extensive questionnaire was completed by 125 and 68 firefighters in 2000 and 2010, respectively. The data were analysed with the Mann–Whitney U test and binominal test and ranked on the basis of the responses in each category. Results. Significant differences were seen between the full- and part-time firefighters. The work tasks rated as the most physically strenuous in terms of aerobic fitness, muscle strength, work posture and body control by most respondents were smoke diving upstairs (carrying a hose), victim rescue in different ways, carrying a stretcher over terrain and pulling a hose. Conclusions. Physically strenuous work tasks should be included in the end-point performance variables used to select physical performance tests for firefighters. The part-time firefighters with no experience in several of the work tasks suggests that work-related exercises are important if both groups of firefighters are expected to do similar work.

Opis:
Wstęp: Celem pracy była ocena obciążenia układu ruchu i jego zdrowotnych konsekwencji u ładowaczy nieczystości stałych, niezbędna do opracowania propozycji działań w kierunku minimalizacji przeciążeń układu ruchu. Materiał i metody: Badaniem objęto 15 ładowaczy w wieku 25-50 lat. Informacje na temat charakterystyki stanowiska pracy i subiektywnych odczuć pracowników w zakresie uciążliwości pracy oraz występowania dolegliwości uzyskano, stosując wywiad wolny i badanie kwestionariuszowe. Ponadto wykonano fotograficzną rejestrację typowych czynności roboczych oraz przy użyciu systemu GPS rejestrację drogi przebytej przez ładowaczy i szybkości ich przemieszczania się, pomiar siły niezbędnej do przemieszczania pojemników ze śmieciami, pomiar wydatku energetycznego (metodą kalorymetrii pośredniej), ocenę obciążenia przy użyciu systemu FirstBeat i metodą REBA oraz pomiar długości kręgosłupa metodą stadiometryczną. Wyniki: Ładowacze pracujący w zespołach 2-3-osobowych pokonują dziennie pieszo ok. 15 km w rejonach miejskich, a w wiejskich - ok. 18 km. Dolegliwości ze strony układu ruchu występowały najczęściej w okolicach stóp (60% badanych), kolan oraz nadgarstków i barków (ponad 40%). U wszystkich pracowników stwierdzono po pracy zmniejszenie długości kręgosłupa o 10-14 mm (średnio: 11,4 mm). Wnioski: Wyniki przeprowadzonych badań wskazują na bardzo duże obciążenie fizyczne ładowaczy spowodowane sposobem wykonywania pracy i jej organizacją. Z tego względu konieczne jest wprowadzenie interwencji ergonomicznych, które powinny uwzględniać m.in. szkolenie pracowników w zakresie prawidłowych sposobów wykonywania pracy, wypoczynku aktywnego i biernego, ale także kontrolę stanu technicznego wyposażenia i pojemników na śmieci oraz renegocjację umów z klientami, zwłaszcza w zakresie ponadnormatywnego ładowania pojemników.

Background: The aim of this work was to assess the load on the musculoskeletal system and its effects in the collectors of solid refuse. The rationale behind this study was to formulate proposals how to reduce excessive musculoskeletal load in this group of workers. Material and Methods: The study group comprised 15 refuse collectors aged 25 to 50 years. Data about the workplace characteristics and subjective complaints of workers were collected by the free interview and questionnaire. During the survey the photorecording of the workpostures, the distance and velocity by GPS recorders, measurements of forces necessary to move containers, energy expenditure (lung ventilation method), workload estimation using the Firstbeat system and REBA method and stadiometry were done. Results: The distance walked daily by the collectors operating in terms of 2 to 3 in urban areas was about 15 km, and in rural areas about 18 km. The most frequent musculoskeletal complaints concerned the feet (60% subjects), knees, wrists and shoulders (over 40% subjects). After work-shift all examined workers had vertebral column shorter by 10 to 14 mm (11.4 mm mean). Conclusions: The results of our study show that the refuse collectors are subjected to a very high physical load because of the work organization and the way it is performed. To avoid adverse health effects and overload it is necessary to undertake ergonomic interventions, involving training of workers to improve the way of their job performance, active and passive leisure, technical control of the equipment and refuse containers, as well as the renegotiation of contracts with clients, especially those concerning non-standard containers.

Opis:
Ergonomics in healthcare is still in its infancy. The responsibilities of healthcare personnel include taking care of the health of the whole population. That is why it is very important to care about healthcare personnel. This article is a presentation of a survey conducted in Slovakia. The survey focused on nurses who work directly at their patients’ beds. The objective of the survey was to verify the physical load of nursing profession and to determine the most frequently musculoskeletal disorders of nurses. The survey was conducted in the form of the Nordic Questionnaire. The results of the survey confirmed the most serious difficulties for nurses with the musculoskeletal apparatus. The results also showed pain-related dependence in one body part of a nursing professional depending on his or her profile. However, the analyses included in this article can be applied to any company management, not only nurses.

Opis:
Provision of professional work is very often associated with the worker's exposure to the occurrence of various types of threats. Some of the most important include those related to physical overload. Excessive strain on the musculoskeletal system can lead to muscle, ligament and tendon injuries. Therefore, it is necessary to evaluate the workplace in terms of its ergonomics. This paper presents the assessment of the load of the worker's movement system using the REBA method, which takes into account the location of: head with neck, torso, lower limb, as well as hands with the wrist, forearm and arm.
