Chronic Lower Back Pain and Its Relationship with Vibration Exposure and Sitting Duration; A Cross-Sectional Study Among Commercial Motorcycle Driver

Abstract

Background: Lower back pain (LBP) complaints are a health issue that may lead to restrictions on work activities. Motorcycles vibrations and long sitting duration on the motorcycles can cause chronic lower back pain complaints. Base motorcycles drivers receive motorcycles vibration exposure while riding a motorcycle. With the large number of base motorcycles drivers in Indonesia, the specific health problems (LBP complaints) in this group need to be examined.Methods: This research method uses a cross sectional study design to examine the relationship of motor vibration exposure and length of sitting to chronic low back pain with sampling technique used is Consecutive sampling. Consecutive sampling is a way of taking samples by selecting samples that meet the inclusion criteria until a certain time period so that the number of samples is met. The sampling period in this study is 2 days. The variables that measured were chronic lower back pain complaints, vibration, long sitting time, age, IMT, smoking, and working time. Data analysis using SPSS Statistics version 25.0. Results: A total of 95 subjects were included in this study. Based on Fisher’s test, the result of the correlation of chronic lower back pain complaints with motor vibrations > 0.5 m/s2 was obtained p = 0.102; OR = N / A). While for long sitting time of >4 hours result in p = 0.717; OR 0.85; CI 95% = 0.34-2.09. There is no difference in age-related chronic lower back pain complaints. At age> 35 years of age p = 0.722; OR 1.57; CI 95% = 0.31-7,9. No significant association between IMT and chronic lower back pain was found. In the IMT group> 25, p = 0.103 was obtained; OR 2.14; 95% CI = 0.85-5.36. There was no significant difference in chronic lower back pain complaints based on smoking status, where smoking group had p = 0.451; OR 1,45; CI 95% = 0.55-3.78. According to the Fisher test, there was no difference in chronic lower back pain complaints based on working age, where groups with> 4 years of work had a p = 0.908 value; OR 1.07; CI 95% = 0.31-3.91. Conclusion: In this study the hypothesis was rejected. There is no association between motorcycles vibration exposure and the occurrence of chronic lower back pain complaints in the base motorcycles driver in Bekasi city. There is no association long sitting time with the occurrence of chronic lower back pain complaints in the base motorcycles driver in Bekasi city.

Hubungan Whole Body Vibration Dengan Disabilitas Low Back Pain Pada Pengemudi Ojek

“…12 Getaran mekanik yang dihasilkan oleh bidang getar dapat disebarkan atau ditransmisikan ke seluruh bagian tubuh dan meningkatkan risiko terjadinya LBP pada pekerja. 13,14 Laporan studi epidemiologi menunjukkan bahwa angka kejadian yang terpapar WBV lebih tinggi pada kelompok pekerja. 12,15 Kelompok pekerjaan yang dikatakan memiliki risiko lebih besar untuk mengalami WBV adalah pengemudi kendaraan off-road, pengemudi kendaraan bermotor, mesin industri, bus, dan pilot helikopter.…”

“…Namun penelitian yang dilakukkan oleh Siagian B, dkk pada 95 orang pengemudi sepeda motor di Jakarta mendapatkan hasil tidak ada hubungan antara paparan getaran dan LBP kronis. 13 Pekerjaan sebagai pengemudi ojek sangat berisiko terpapar getaran sepanjang hari dan penelitian sebelumnya yang mengukur hubungan WBV dengan LBP pada pengemudi ojek online menggunakan instrumen yang berbeda dan masih ada kontradiksi hasil. Hal ini membuat penelitian ini berbeda dengan penelitian hubungan antara paparan getaran WBV dan nyeri pinggang pada pengendara kendaraan bermotor yang pernah dilakukan.…”

“…Kontraksi terus menerus dapat mengakibatkan peredaran darah tidak lancar, sehingga meningkatnya penumpukan asam laktat, dan menimbulkan rasa nyeri pada otot. 13,14,15 Getaran yang dipaparkan oleh mesin pada pekerja secara terus menerus akan berdampak pada kerusakan jaringan serta organ tubuh pekerja. Melakukan pekerjaan dalam waktu yang lebih lama di kendaraan atau pada lingkungan kerja yang memiliki bahaya getaran tinggi berpotensi menimbulkan nyeri pada pinggang.…”

“…Melakukan pekerjaan dalam waktu yang lebih lama di kendaraan atau pada lingkungan kerja yang memiliki bahaya getaran tinggi berpotensi menimbulkan nyeri pada pinggang. 13,14,15,16 Getaran seluruh tubuh atau WBV yang dihasilkan dari kendaraan motor akan menimbulkan keluhan nyeri punggung bawah ketika pengemudi menghabiskan waktu yang lebih lama pada kendaraan yang mempunyai getaran melebihi NAB.…”

Developing adjustable stiffness for smart material of magnetorheological elastomer to diminish vibration

“…Hence, several configurations have been tested by adjusting the various parameters (i.e., matrix material, additives, size, percentage content, type, and the shape of the fillers to produce a more effective MRE based on the MR effect [1,3,4,5,11,12,13,14,15].…”
