Operators of heavy equipment are often exposed to high levels of whole-body vibration (WBV), which has been associated with a variety of adverse health outcomes. Although anthropometric factors are known to impact vibration dose and risk of low back pain, studies have yet to investigate the influence of anthropometric factors on muscle activation during WBV exposure. This study quantified the relationships between muscle activation, vibration frequency, body mass, body mass index (BMI), and height both pre- and post-fatigue. Muscle activation of the external oblique (EO), internal oblique (IO), lumbar erector spinae (LE) and thoracic erector spinae (TE) were quantified using surface electromyography. Results indicate increased activation with increased mass, BMI, and frequency for the LE, TE, and IO, which may be a result of increased activation to stabilize the spine. Decreased muscle activation with increased height was seen in the TE, IO, and pre-fatigue EO, which could indicate higher risk for low back injury since height is associated with increased forces on the spine. This may contribute to the association between increased low back pain incidence and increased height. Results suggest that ISO 2631-1 health guidance should incorporate anthropometric factors, as these may influence muscle activation and back injury risk.

<p><em>Low back pain is a common disease affecting almost all individuals at some point in their life. Low back pain is multifactorial in origin. The cause of increased prevalence of low back pain in populations of professional drivers is often uncertain. The factor reported to be most strongly associated with low back pain are exposure to whole body vibration. Other possible risk factors with weaker or inconsistenst evidence for influencing low back pain are individual factors (age, time of work, body mass index and physical activitity). This research is conducted observasionally with cross sectional design with a large sample of 70 people which selected by purposive sampling. Data collected from accelerometer, questionnaires, observation and interviews. The results of research obtained that exposure whole body vibration suffered by operator is 0,543 m/s<sup>2</sup> and complaints of low back pain on a heavy equipment operators at PT. X is 64,3 %. Bivariat analysis showed that there are significant relationship between whole body vibration (p&lt;0,05;95 % CI 0,99-2,99 OR 1,723), age (p&lt;0,05; 95 % CI 1,42-3,77 OR 2,31), time of work (p&lt;0,05; 95 % CI 1,07-7,81 OR 2,89) with low back pain. There was no significant relationship between body mass index (p&gt;0,05; 95 % CI 0,68-1,37 OR 0,969) and physical activity (p&gt;0,05; 95 % CI 0,55-1,14 OR 0,798) to low back pain. This research conclude that there is correlation whole body vibration with complaints of low back pain. </em></p><p><strong>Keyword:  </strong><em>whole body vibration, low back pain, operator</em></p>

Does body mass index increase the risk of low back pain in a population exposed to whole body vibration?

Abstract BackgroundWhole body vibration (WBV) training as an intervention method can cure chronic low back pain (CLBP). Different WBV parameters exert different effects on lumbar-abdominal muscle performance. Currently, there is a lack of study researched the influence of WBV training on patients with CLBP by lumbar–abdominal muscle activity. Therefore, this study aimed to investigate how WBV and exercise and their interactions influence lumbar-abdominal muscle activity in patients with CLBP.Methodsa group of ambulatory patients with chronic low back pain. Muscle activities of the multifidus, erector spinae, abdominal oblique externus muscle and the rectus abdominis muscle were measured by surface electromyography, whereas participants performed 4 different exercises during three whole body vibration conditions and a no-vibration condition in a single experimental session.ResultsCompared with the same exercises without whole body vibration, muscle activity increased when whole body vibration was added to the exercises. The frequency and exercise presented significant effects on the root mean square of multifidus, whereas exercise and frequency also resulted in significant interaction effects.ConclusionAdding whole body vibration to exercise could increase muscle activation of lumbar–abdominal muscle in patients with CLBP. The optimum frequency for lumbar–abdominal muscles is 15 Hz. The best exercises include plank for multifidus and erector spinae, V crunch for rectus abdominis and single bridge for abdominal oblique externus.Trial registration:ChiCTR-TRC-13003708.
