Companies that have manual work, muscle injury is one of the major health issues that often occur when working. XYZ Ceramics Yogyakarta is still doing work activities involving manual processes and there has been identified that worker posture has the potential to cause injury. From the Nordic Body Map questionnaire, complaint was identified in the back were 88%, the knees were 80%, the upper arm 75%, and the right shoulder by 70% from 15 workers. The Ovako Work Posture Analysis System (OWAS) method is used to evaluate and analyze work attitudes so that improved categories of work methods and recommendations could be obtained. Plan for Identifiering av Belastningsfaktorer (PLIBEL) was used to identify the factors that cause muscle injury or harmful effect. In addition, the Nordic Body Map was applied to determine the critical work station. The purpose of this research is to analyze work posture and description of risk level related to musculoskeletal injury at critical work station. The three highest percentage of risk of muscle injury identified at raw material processing station, based on calculation result of PLIBEL Checklist, were on elbow, forearm, and hand. Based on the assessment of working posture using OWAS, the highest action category is identified in the activity of moving the cart containing the soil to the automatic pest that is the action category of 4, which means that this activity is very dangerous for the musculoskeletal system.

Slouching and squatting work postures in the fish cleaning process can cause skeletal muscle injury. Based on the results of previous research conducted by Adelia (2020), the results of the existing NBM show that workers have complaints in the muscles of the neck, arms, back, waist, buttocks, hands, wrists, thighs, knees, and feet. The result of total muscle complaints individual skeletal is 75, meaning that the existing work posture requires work improvement. Improvement of working posture can be done by designing work aids in the form of desks and chairs. The determination of the MSDs risk level category was carried out by identifying the skeletal muscle complaints felt by workers using a Nordic body map (NBM) questionnaire, a working posture assessment was carried out to determine the score level in work posture using the Rapid Upper Limb Assessment (RULA) method with the help of CATIA V5R20 software. Assistive devices in the form of desks and work chairs are designed based on complaints experienced by workers and use the anthropometric approach in determining the dimensions of work aids. Based on the results of the implementation of work aids, there was a change in the score for skeletal muscle complaints and work posture. The results showed that the average NBM value of individual muscle complaints was 56.75, this is included in the moderate risk level and the results of the RULA analysis on the repair work posture experienced a change in the final score, namely 4 (yellow).

There is growing evidence, from epidemiological and biomechanical sources, that lifting performed in asymmetric postures is a risk factor for the development of a musculoskeletal injury. In the recent update of the NIOSH Lifting Guide, a linear Asymmetric Multiplier was added to account for this type of risk. The present study addresses the form of this Multiplier through analysis of several asymmetric lifting tasks. Both spinal loading and a derived metric of muscle injury risk were calculated as a function of asymmetry angle. The results suggest that there is a non-linear increase in injury risk with respect to asymmetry. Only moderate increases in risk were predicted for asymmetry of 0°–30°, and sharply increasing risk as asymmetry reaches 90°, implying that ergonomic intervention should be concentrated on tasks with the highest asymmetries.

Musculoskeletal disorders (MSDs) are diseases in the human muscular tissue system in the back, wrist, knees and shoulders caused by incorrect postur during work activities. This study was conducted to determine the level of risk MSDs on operator work activities at the cast house work station. Activities under study are activities; surface repair tap hole, checking temperature iron, and take iron sample. These activities are carried out repeatedly, incorrect work posture and the presence of  heat from work environment factors that affect the whole body. This makes the operator complain of pain in parts of the body at risk of developing musculoskeletal complaints. This study was an observational study using the Rapid Entire Body Assessment method and the Nordic Body Map instrumen. The result of the Nordic Body Map instrumen for 20 operators at the cast house work station showed that there were 21 complaints against operator. Based on the measurement of cast house operators the surface repair activity of tap holes has a “high” risk value for MSDs (REBA Score 9), checking temperature iron activities have a “low” risk value for MSDs. Proposed improvement to prevent is to improve the procedur in the surface repair activities of tap holes, where when the process of sticking the dough is done in front of the tap hole is changed by attaching it to the mud gun nozzle tip. After the proposed improvement, the result of the Nordic Body Map instrumen showed no complaints and the measurement of the tap hole had a “low” risk value for the occurrence of MSDs (REBA Score 3).

Based on the REBA analysis, there is a risky operator work postures in the warping work station at PT. Iskandar Indah Printing Textile because they do not use work tools. The assessment of the level of work posture risk by the REBA method gets the result that the highest work element with a final score of 10 is obtained by taking warp yarn at the warping station. This study aims to produce a design tool to reduce the level of work posture risk in warping work station operators. Then the design of tools was carried out by the Pahl and Beitz method to produce three alternative product design concepts. Based on the three ideas, the best plan is chosen by using an Engineering Design Selection, and the result is the second design concept. The selected design is an adjustable trolley with a vertical screw drive system that is comfortable to use and does not cause a bending position on the operator because it has a trolley plate that can be adjusted in height as needed. The use of the trolley causes a decrease in the level of work posture risk from a high-risk level to a small risk level with a final score of 10 to 3.

ObjectivesThis study assessed knowledge, beliefs and practices of elite female footballers regarding injury prevention.MethodsA survey was sent to players participating in the FIFA Women’s World Cup France 2019. Questions covered three injury prevention domains: (1) knowledge; (2) attitudes and beliefs; (3) prevention practices in domestic clubs. Additionally, ACL injury history was assessed.ResultsOut of 552 players, 196 women responded (35.5%). More than 80% of these considered injury risk to be moderate or high. Players listed knee, ankle, thigh, head and groin as the most important injuries in women’s football. The most important risk factors identified were low muscle strength, followed by poor pitch quality, playing on artificial turf, too much training, reduced recovery and hard tackles. In these elite players, 15% did not have any permanent medical staff in their domestic clubs, yet more than 75% had received injury prevention advice and more than 80% performed injury prevention exercises in their clubs. Players identified the two most important implementation barriers as player motivation and coach attitude. Two-thirds of players used the FIFA 11+ programme in their clubs.ConclusionsThis diverse group of elite players demonstrated good knowledge of risk level and injury types in women’s football. Of the risk factors emphasised by players, there was only one intrinsic risk factor (strength), but several factors out of their control (pitch quality and type, training volume and hard tackles). Still players had positive attitudes and beliefs regarding injury prevention exercises and indicated a high level of implementation, despite a lack of medical support.

OBJECTIVES: To investigate intra- and inter-rater reliability of a ballet-based Dance Technique Screening Instrument used by physical therapists (PTs) and student PTs (SPTs) with prior dance medicine or dance experience. METHODS: Ten pre-professional dancers were video-recorded in the sagittal and frontal planes while performing four dance sequences: 1) second position grand plié; 2) développé à la seconde; 3) single-limb passé relevé balance; and 4) jumps in first position. Dance videos and electronic versions of the demographics and scoring forms were provided through a secure online survey to 28 PTs and SPTs who served as raters. Raters reviewed a training video prior to scoring the 10 dancers. Raters were asked to repeat their assessments 1–2 wks later. Intraclass correlations (ICC) were assessed for all-raters, PTs, and SPTs for total and sequence scores. RESULTS: Twenty-eight raters assessed the videos one time. Inter-rater reliability was ICC=0.98 (CI95=0.96–0.99) (all-raters), with PTs and SPTs displaying similar values (ICC=0.96 and 0.96, respectively). Eighteen raters (11 PTs, 7 SPTs) repeated the video analysis. Intra-rater reliability was ICC=0.78 (CI95=0.72–0.83) with PTs ICC=0.81 and SPTs ICC=0.70. CONCLUSIONS: Correlations were high for all-raters. SPTs were as reliable as PTs in inter-rater comparisons. PTs exhibited higher intra-rater reliability compared to SPTs. These results substantiate the reliability of a standardized testing instrument to conduct dance technique assessment. Validity of this instrument was demonstrated in a previous study which found dancers with better technique were less likely to sustain injury. The ability to identify technique deficits can guide preventative programs that may reduce injury risk. LEVEL OF EVIDENCE: Level III.
