Buses are one of the important public transportation in Malaysia and commonly important for the student in any university. Thus, the study about Whole-Body Vibration (WBV) exposure induces to Low Back Pain (LBP) among the Universiti Tun Hussein Onn Malaysia (UTHM) was done. The objective was determine whether the bus drivers in UTHM would exceed the exposure action and limit values from the ISO 2631-1 (1997) during the working hours. Data collected according to different type of buses and evaluated the vibration significant different between buses based on the subjective correlation due to WBV questionnaire analysis. Analyze the prevalence of LBP based on the measurement and the questionnaire analysis. The study based on the international standard ISO 2631-1 (1997) which is related to the root-men-square (r.m.s) and Vibration Dose Value (VDV) parameter. The study covered among the bus drivers in UTHM. The measurement tools involved in the study is Larson Davis Vibration Meter (HVM 100) with Tri-axial Seat Pad Accelerometer to record data collection. The BLAZE software analyze the vibration exposure exceed the total vibration exposure according to 8 hours day A(8) value of 1.15 m/s2 and VDV value of 21.0 m/s1.75. The IBM Statistical Package for Social Science (SPSS) was used to do statistical analysis and testing involved was correlation, regression and ANOVA. Result obtained shows the A(8) and VDV was under EAV with highest value of 0.520 m/s2 and12.65 m/s1.75. The highest contribution factors by the duration to complete single trip per day (α=0.500).The further re-assess of working schedule need to be done in order to control the exposure level toward drivers. The assessment should be done for every two years.

Neuromotor Control

Low back pain is one of the most costly and common musculoskeletal disorders, affecting up to 80% of the adults in their lifetime [1]. Whole body vibration (WBV) has been found to be a major risk factor in the etiology of low back pain with WBV increasing low back disorder risk from 1.2 to 39.5 fold depending on the occupational exposure duration and magnitude [2–3]. Recent research has demonstrated that exposure to sinusoidal whole body vibration of 5 Hz leads to increased propriceptive errors and delayed neuromotor response to external perturbation [4]. These results suggest a potential mechanism for low back injuries, namely that vibration may alter neuromotor control leading to poor stabilization and control of low back motion, increasing the risk of injury. However, the methods used to assess these changes in proprioception are static measures, require a good deal of equipment and setup time, and have a high variance, particularly with removal of electrodes and sensors, that make them impractical for the industrial setting. In addition, previous studies have only examined the effect of pure sinusoidal vibration exposure rather than the mixture of frequencies seen in occupational settings. Therefore, the goal of this project was to develop a dynamic measure of lumbar sensory accuracy and neuromotor control that could be used easily in the workplace and to examine the effects of WBV vibration on the measure using an occupationally-relevant vibration exposure.

The aim of the study was to investigate the relationship between exposure to whole body vibration, prevalence of low back pain and level of physical fitness in bus drivers. The measurement of whole body vibration was in 100 city buses with different characteristics and the prevalence of low back pain was assessed in 200 drivers with a measurement of physical fitness level. Descriptive statistics with mean and standard deviation and inferential statistics were used with the Kurskal-Wallis test, Dunn's multiple comparisons test, Poisson regression and significance level of p <0.05. The results demonstrate significant differences between the vehicle models, characterizing the conventional and articulated buses on the y and z axes with higher levels of vibration. Drivers working with conventional and articulated vehicles had a higher prevalence of low back pain with 57.5 and 60%, respectively. The level of physical fitness was low in most of the sample, however, the drivers of bi-articulated and micro bus had higher levels. Poisson regression with the outcome of low back pain, showed the factors that showed a significant prediction: age, working time, abdominal muscle resistance, lumbar strength, RMSy and RMSz.
