Musculoskeletal disorders are the most common among farmers and farming constitutes the highest industrial accident rate. To prevent these, we developed a smart auxiliary workwear and investigated its effectiveness through human impact assessment experiments. In our method, the actuator of the waist elastic band was released when there was no need to directly adjust the length with the strength support of the waist, and the elastic band was held once the motion using the waist strength disappeared. To examine the performance, 15 workers were recruited; before the experiment, they were subjected to a basic fitness evaluation to examine their general characteristics. The lumbar peak torques before and after wearing the designed work clothes were measured using the Biodex System III to determine their lumbar assistance power, which was confirmed to have increased by approximately 17%. In addition, electromyographic comparison of the amount of muscle used before and after the wearing revealed that the muscle use was reduced by 26.41% and 19.38% after wearing the work clothes when the weight was lifted in the stooping and squatting postures, respectively. Based on these results, it can be stated that the proposed smart assistive work clothes could contribute to reduced muscle usage required for work and lessen related weariness by supporting the waist, and thus, would greatly help farmers in preventing 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.

Background.Work-related musculoskeletal disorders (MSDs) are a group of painful disorders of muscles, tendons, and nerves, such as neck and shoulder MSD. This study was designed to use miniscalpel-needle (MSN) technique as an intervention for work-related MSDs.Methods.Thirty-one patients with work-related MSDs and 28 healthy subjects were enrolled as controls in this study. The MSD symptoms of each patient were assessed by visual analog scale (VAS) and neck disability index (NDI). Blood samples were collected from control subjects and MSD patients before and after treatment. Serum levels of C-reactive protein (CRP) and tumor necrosis factor (TNF) were measured using ELISA.Results.Prior to MSN treatment, serum levels of CRP and TNF were significantly higher in the MSD patients than the healthy controls. Serum CRP levels correlated with VAS and NDI scores, and serum TNF levels correlated with NDI scores. Compared to pretreatment, VAS and NDI scores were significantly lower in MSD patients after MSN treatment, while serum CRP and TNF levels were significantly lower compared with the healthy control levels.Conclusions.Our results indicate that MSN may be an effective intervention for work-related MSDs and be associated with lower serum levels of inflammatory biomarkers.
