Abstract

The quasi-experimental research objective was developing drop grain tank for awkward posture prevention and reducing low back pain. This is the case study among 30 rice farmers, Moo 9, Ban Keknoi Tambon, Keknoi KhaoKho District and Phetchabun Province. The standard questionnaire was used to compare pre- and post- data such as Numeric Rating Scale (NRS) to measure the low back pain scale, Rapid Upper Limp Assessment (RULA) to evaluate awkward posture. Data analysis was done using frequency, percentile and Paired t-test. The results showed that the rice farmers who planted the seeds were mostly female (96.7%), age mean 41.6 years old (S.D = 10.5 years) , BMI range normal weight (46.7%), study at primary school (53.3%), job experience mean 26.7 years, average work hours 7.6 hours a day. RULA scale to evaluated posture using the native pattern was 6.5, after that to use drops grain tank decrease RULA scale was 4.1 statistically significant (p = 0.001). And pain scale for low back pain was 7.3, the pain scale was decreased after that to used drops grain tank to 6.7 (p = 0.001). The finding also showed that the drops grain tank can reduce the awkward posture and affect to relive the low back pain. This is the first research that developed the drop grain tank for rice farmers in upper land that was informal workers who should to awareness for health from career.
