Rapid Entire Body Assessment

Background and Objectives: This study aimed to determine the prevalence rate of musculoskeletal disorders and evaluate the body position in routine tasks among orthotists and prosthetists. Methods: Forty orthotists and prosthetists were included. The scores of the Nordic Musculoskeletal Questionnaire and the Rapid Entire Body Assessment were used to determine the prevalence rate of musculoskeletal disorders and analyze the work position of orthotists and prosthetists, respectively. An examiner evaluated 10 working postures that were dominantly used every day, in each orthotist and prosthetist. Results: Among the orthotists, 55.6% of men and 47% of women suffered from pain in the trunk, neck, and lower limbs. Nearly similar results were seen in the upper limbs (74.1% men and 45.5% women). Such high prevalence rates were not seen in prosthetists. The analysis of the Rapid Entire Body Assessment scores based on the working task and gender of the orthotist and prosthetist showed that more than 60% of the workers achieved a score of 4 to 7 approximately in half of the tasks. It shows the medium risk of musculoskeletal disorders, thus, corrective action is necessary. Conclusion: Based on the findings, musculoskeletal disorders are highly prevalent among orthotists and prosthetists, especially in the orthotist workers. To reduce these disorders, it is recommended to add ergonomic topics and training courses for working with devices to increase the knowledge of specialists and apply and select practical tools based on the principles of ergonomics.

Background: The automotive industry is heavily affected by sick leaves caused by the handling of loads and using postures that produce musculoskeletal disorders. Research is needed to analyse their causes and find possible solutions to eliminate or mitigate these risks. Objective: Our objective was to analyse the level of musculoskeletal risk in the different work tasks performed by truck and bus mechanics. Our intention is also to analyse whether postural training and feedback can help reduce risk. Methods: The rapid entire body assessment (REBA) was used to assess the postures performed by 35 mechanics from eight branches throughout Spain. The participants were subsequently divided randomly into two groups (experimental group and control group). The experimental group (EG) was given training and feedback on their postures and the control group (CG) was not offered any type of intervention. A few months after the initial assessment, their postural load in the usual tasks was re-evaluated. Results: An overall average REBA Score: 10.49 ± 1.33. The main risk was found in the trunk and arms with sustained above-the-head postures. EG’s second results are significantly improved compared to the first (p = 0.026 *). Conclusions: These jobs have a high-risk level of musculoskeletal disorders. The course of action presented with postural training and feedback has shown satisfactory results. Nevertheless, given the size of the sample, further research will be needed to delve deeper into this possibility as a future line of intervention.

The making of Indonesian soccer robot in the division of the Indonesian Football Robot Contest (KRSBI) especially in the process of coil rolling machines on a solenoid does not pay attention to ergonomic factors. The process of winding the wire on the solenoid is done using only the hands manually and in an un ergonomic body position, which is turning and bending. As a result, the convolution process lasts longer and in the wrong posture, causing fatigue and back pain. Macroergonomic Analysis and Design (MEAD) and Rapid Entire Body Assessment (REBA) approaches are used to analyze the posture of the wire. The solution is obtained by design and making an ergonomic and semi-automatic coil rolling machines to solenoid Robot based on the Arduino Microcontroller

Qfd Method

The Musculoskeletal disorder (MSDs) is skeletal muscle disorders that lead to damage in nerves, muscles, joints and cartilages. The damage is caused by muscle tension and degeneration. From the preliminary research in virgin coconut oil (VCO) processing industry, Central Java, Indonesia, there are potential risk of MSDs for workers. The majority of operators complaining on the right thigh (score 37) and left thigh (score 35). In addition, 50% of operators is work with moderate risk (rapid entire body assessment scores 4-7) and 50% others at a high risk level (rapid entire body assessment scores 8-10). Therefore, improvement is needed to prevent MSDs through work facility design using an integrated quality function deployment (QFD) method. In QFD, there is a concept screening phase to select some product design concept. To determine the priority, the QFD method can be integrated with analytic hierarchy process (AHP) method. The research shows that attributes of work facility needed by user are ergonomic, portable, durable and aesthetic. Concept design B have the highest priority score 0,32 and selected as the final work facility design. The technical specification are made from mahogany wood with an attractive design, red colour combination and developed based on user's anthropometry data.

Rapid Entire Body Assessment

COVID-19 has become a global pandemic, and one of the government's actions in the education sector to prevent transmission through online class activities or online classrooms has been adopted. During the pandemic, it was discovered that using computers with improper or non-ergonomic body postures during online classes might cause muscular fatigue and raise the incidence of musculoskeletal problems. Using the Rapid Entire Body Assessment (REBA) method, this study seeks to detect musculoskeletal complaints and assess the posture of UMM students when using a laptop. Because online learning lasts more than 2 hours, posture that is not in accordance with the comfort of using a laptop can lead a person to exhaust more rapidly in front of a laptop for a relatively long period, especially in the upper neck, back, and waist, which stand for 80% of the body parts. This is supported by the study of respondents using a questionnaire distribution technique that provided a REBA score of 7 and a moderate risk level, indicating that remedial action is required. After a recommended improvement with a low risk level for MSDs, a REBA score of 3 was established. Suggestions that can be considered are that it is necessary to improve sitting work posture, it is recommended to work on a table and sit in a reclining chair so that the proposed work posture improvement can be carried out.

Musculoskeletal disorders (MSDs) atau gangguan otot rangka merupakan kerusakan pada otot, saraf, tendon, ligamen, persendian, kartilago, dan discus invertebralis. Penyebab utama terjadinya MSDs adalah postur tubuh yang salah. Postur tubuh adalah posisi bagian dari tubuh yang berhubungan dengan bagian tubuh lain yang dihubungkan oleh sudut sambungan. PT ABO FARM merupakan sebuah perusahaan yang bergerak dibidang pertanian dimana memfokuskan bisnisnya pada ekspor sayuran khususnya sayuran buncis yang berada pada kawasan desa Nengkelan, kecamatan Ciwidey, kabupaten Bandung. Salah satu kegiatan pada PT ABO FARM yaitu kegiatan loading sayuran buncis dipengumpul dengan menggunakan karung. Karung yang diangkat memiliki dimensi 96 x 43 x 36 cm dengan kapasistas sebesar 55 kg, padahal batas kapasitas yang direkomendasikan oleh NIOSH adalah sebesar 23 kg. Berdasarkan hasil penelitian postur kerja operator yang sedang melakukan handling material dengan menggunakan REBA (Rapid Entire Body Assessment) diperoleh skor assessment sebesar 12. Nilai ini mengindikasikan bahwa postur kerja berada dalam posisi yang berbahaya sehingga diperlukan perbaikan saat ini juga. Maka dari itu, untuk melakukan perbaikan postur kerja maka pertama kali perlu dilakukan perbaikan pada material handling eksisting. Metode rasional merupakan suatu metode pendekatan yang sistematis. Metode ini banyak digunakan pada tahapan perancangan sebab memiliki tahapan yang jelas, sehingga dapat memberikan hasil rancangan dan produk akhir yang berkualitas. Setelah dilakukan design perancangan material handling, maka diperoleh skor pengangkatan sayuran buncis sebesar 2, sehingga diperoleh kesimpulan bahwa produktivitas penggunaan material handling usulan meningkat sebesar 83 persen.

Introduction. Osteoarthritis is considered a complex biopsychosocial condition, with consequences for the patient, the family, society and public health. Age is considered the main risk factor in the occurrence of osteoarthritis. Studies show that 2 out of 3 obese individuals associate knee osteoarthritis whereas the incidence of the latter increases at the same time with increasing body mass index. Obesity contributes to the initiation of the process of osteoarthritis by the mechanical overload of the joint, causing cartilage damage with increasing horizontal cracks and the increased incidence of the osteophites in the knee. Purpose. We conducted a study in patients with knee osteoarthritis and body mass index with normal and high values, evaluating pain, functional capacity and maximum travel distance by applying electrotherapy and kinesiotherapy. Material and method. We studied a number of 68 patients diagnosed with knee osteoarthritis, who received as therapy electrotherapy and physiotherapy. The VAS scale, the WOMAC scale, the joint balance and the Lequesne scale were used to evaluate patients.The objectives of the study were: pain reduction, improved postural control and coordination, control of the gravity center, correction of alignment at the lower limbs, re-education of gait, obtaining a body mass index as close to normal. Results and discussions.The total group of patients was homogeneous according to age and gender. The evaluation of patients based on scales recorded superior values in the study group, with statistically significant results, worth p <0.05, which means that the hypothesis was validated. Conclusions. The use of the recovery treatment was individualized and took into account the condition of the affection, the body mass index, the ability of patients' mobility and algic symptoms.

Background: Musculoskeletal complaints have been common for dentists since their body is unknowingly often in inappropriate positions when caring for patients. For example, they bend towards patients, suddenly move, and then rotate from one side to another. The repetitive movements are done in long term. High activities and sufficient recovery time can cause a buildup of lactic acid in their blood leading to obstruction of the energy intake from the aerobic system in their muscle cells, resulting in fatigue. As a result, such conditions trigger decreased muscle performances. Purpose: This study aimed to determine the correlation between working positions and lactic acid levels with the risk of musculoskeletal disorders among dentists at Public Health Centers in Surabaya. Method: This research was an analytical observational research using cross sectional approach. Sampling technique used in this research was cluster random sampling with nineteen samples. To evaluate the working positions of those samples, a rapid entire body assessment (REBA) method was used. Meanwhile, to observe the musculoskeletal disorders of those samples, a Nordic body map was used. Data obtained then were analyzed using Pearson correlation test with a significance level (p<0.05). Result: Results of data analysis using the Pearson correlation test showed that the significance value obtained was 0.036. It indicates that there was a correlation between the working positions and the lactic acid levels with the musculoskeletal disorders in those dentists. The results of the Pearson correlation test also revealed that there was a correlation between the working positions and the lactic acid levels among those dentists with a significance value of 0.025. Conclusion: It may be concluded that the wrong body positions during working can increase lactic acid level in the body of dentists. The increased level of lactic acid then can affect their muscles, leading to the high risk of musculoskeletal disorders.
