Introduction: Musculoskeletal discomfort is one of the most important causes of occupational injury and disability. The aim of this study was to evaluate the risk factors of musculoskeletal disorders and ergonomic intervention in order to reduce them. Methods: This analytic-descriptive study was conducted on 116 employees of Bandar Abbas Zinc Production Company. The Nordic questionnaire and QEC method were used to collect data before and after the interventions. An intervention program was conducted to reduce the workers' load weight, change their work level height, job rotation, and training. Finally, the collected data were analyzed using SPSS 23. Results: During the last year, the highest frequency of musculoskeletal disorders were 65.52% in the lower limbs, 43.10% in the shoulder, and 43.10% in the knees. According to Cochran test, a significant difference was found between the discomfort before and after the intervention in the organs. Conclusion: The results revealed a significant reduction in musculoskeletal discomfort 3 months after the intervention. As a result, it can be deduced that integrated use of engineering and management interventions in a simple, practical, and cost-effective manner can reduce these diseases. Furthermore, continuous monitoring over appropriate implementation of these interventions over a long period of time along with commitment of the management and employee participation may  reduce the musculoskeletal disorders.

Workload was predicted based on work pulse that was measured using 10 beats method on radial artery with stopwatch. The indication of subjective disorders was measured based on the farmers’ general fatigue and musculoskeletal disorders before and after work. General fatigue was measured using 30 Items Self Rating Questionnaire Industrial Fatigue Research Committee from Japan Association of Industrial Health, while musculoskeletal disorders were measured using NIOSH Nordic Body Map Subjective Filling. Environment temperature was measured using sling Psychrometer. Noise was measured using Gossen’s sound level meter. Statistical analysis to find out the mean difference of the data before and after work was analyzed using t-Paired test with significance level of 5%. RULA result recommended changing from bending work posture using the old tool into standing work posture using new hole maker. The old work posture (P0) showed RULA grand score of 7 with high risk level, while the new work posture (P1) showed RULA grand score of 3 with low risk level. There was significant difference on subjective disorders of the farmers (p<0.05) on P0 and P1 on general fatigue and musculoskeletal disorders. The fatigue score of P0 was 51.27 while P1 was 40.82 which meant there was reduction of 20.4%. While the musculoskeletal disorders score of P0 was 70.75 and P1 was 50.58 which meant there was reduction of 28.5%. It can be concluded that the improvement of work posture using RULA analysis decreases work risk level and subjective disorders of strawberry farmers in Bali.

General fatigue complaints and musculoskeletal disorders are two of the most common symptoms experienced by dialysis nurses, as the products of the poor ergonomic working poses. Ergonomic intervention and stretching in the workplace are needed to reduce the symptoms.  Unnatural pose has a potential to develop general fatigue and musculoskeletal disorders in hemodialysis room where each nurse in every shift is in charge to take care of four patients. The study aims to investigate the improvement of poses of work ergonomically by using ergonomic workplace stretching to reduce complaints in musculoskeletal and general fatigue which in turn can expectedly improve work productivity in hemodialysis room. This study is an experimental study with treatment by subject design. The study was conducted in hemodialysis unit in Wangaya Regional Public Hospital (WRPH) Denpasar from October until December 2019 with 11 people as the participants. As the result, there is no significant difference in the average of musculoskeletal complaints before working with p=0.350 (p>0.05). Meanwhile, the average of musculoskeletal complaints of nurse after working shows a significant difference that is p=0.001 (p<0.05). The analysis result indicates that there is a significant decrease in musculoskeletal complaints, which is 36.18%. The average of general fatigue before working shows no significant difference in score, that is p=0.350 (p>0.05). In the other side, there is a significant difference in score after working with p=0.001 (p<0.05). The analysis result reveals that there is a significant decrease in general fatigue for 66.97%. A significant improvement is shown in the productivity average with p=0.001 (p<0.05). The conclusion of this study is the improvement in poses of work and ergonomic workplace stretching have reduced the complaints in musculoskeletal and general fatigue and also improve nurses’ working productivity in hemodialysis unit.

This study investigated the effectiveness of workstation ergonomic intervention in reducing musculoskeletal disorders (MSD) in Visual Display Terminal (VDT) workers. The study was carried out at one of a Multinational Company in Petaling Jaya, Selangor. Sixty Heavy VDT workers were selected randomly as case study respondents. Questionnaires were given to 60 respondents to investigate their awareness in ergonomic intervention, job-related factors that contributing to musculoskeletal disorders, as well as MSD severity and symptoms among them. Then, 30 workers who are heavy VDT users were selected to receive the education and ergonomics interventions, whereas another 30 receive the education and ergonomic intervention, whereas another 30 workers were assigned as a control group. The two groups were then crossedover after sixth week, and follow-up questionnaire s we given to all of them once again. The results for both questionnaires, before and after the ergonomics intervention, were then analyzed for this case study. The interventions include ergonomics leaflets, ergonomic posters, online ergonomic education and ergonomic working posture guidance. The outcomes suggested that a participation in an ergonomics program, even though in a short duration and minimally disruptive to the normal workplace routine, can still contribute to a rapid effect on improving work posture. Although improper posture is associated to be the main risk factor for work-related musculoskeletal disorders, multigroup and long-term randomized trial are required to establish the effectiveness or workstation ergonomic intervention in reducing musculoskeletal disorders in VDT workers. In conclusion, there is significant evidence that individualized ergonomic interventions may contribute to improve work-related posture and reduce MSD injuries for VDT workers.

Introduction. An osteopathic examination determines the rate, the amplitude and the strength of the main rhythms (cardiac, respiratory and cranial). However, there are relatively few studies in the available literature dedicated to the influence of osteopathic correction (OC) on the characteristics of these rhythms.Goal of research — to study the influence of OC on the rate characteristics of various rhythms of the human body.Materials and methods. 88 adult osteopathic patients aged from 18 to 81 years were examined, among them 30 men and 58 women. All patients received general osteopathic examination. The rate of the cranial rhythm (RCR), respiratory rate (RR) heart rate (HR), the mobility of the nervous processes (MNP) and the connective tissue mobility (CTM) were assessed before and after the OC session.Results. Since age varied greatly in the examined group, a correlation analysis of age-related changes of the assessed rhythms was carried out. Only the CTM correlated with age (r=–0,28; p<0,05) in a statistically significant way. The rank dispersion analysis of Kruskal–Wallis also showed statistically significant difference in this indicator in different age groups (p=0,043). With the increase of years, the CTM decreases gradually. After the OC, the CTM, increased in a statistically significant way (p<0,0001). The RCR varied from 5 to 12 cycles/min in the examined group, which corresponded to the norm. After the OC, the RCR has increased in a statistically significant way (p<0,0001), the MNP has also increased (p<0,0001). The initial heart rate in the subjects varied from 56 to 94 beats/min, and in 15 % it exceeded the norm. After the OC the heart rate corresponded to the norm in all patients. The heart rate and the respiratory rate significantly decreased after the OC (р<0,0001).Conclusion. The described biorhythm changes after the OC session may be indicative of the improvement of the nervous regulation, of the normalization of the autonomic balance, of the improvement of the biomechanical properties of body tissues and of the increase of their mobility. The assessed parameters can be measured quickly without any additional equipment and can be used in order to study the results of the OC.
