“…The synergy in resonance frequencies has been found to amplify the force between L3 and L4 by approximately 360 N. The amplified compression force, coupled with the bent‐forward and leftward leaning position of the pilot, further increases the risk of disc injury. Whole‐body vibration is also tied to increased inflammation of the disc as demonstrated by a study measuring spine height, which found subjects exposed to whole‐body vibration showed an increase in disc height when compared to a measurement taken prior to vibration 20 . This localized inflammatory response causes the intervertebral discs to swell, which increases the risk of annular tears.…”

This review provides a perspective of spinal injuries related to invasive cardiology, an understanding of the anatomy and physiology of the spine, the etiology and pathophysiology of spinal injuries, and options for prevention and treatment. Because of the breadth of this review, it has been divided into two parts with the first describing the biomechanics and generation of back pain and the second discussing treatment options and prevention of back injury. A comprehensive overview of the biomechanics of the spine from the individual vertebral unit to the complex motions involved in everyday life is reviewed. The significant intrinsic and extrinsic factors playing a role in the mechanism of disc damage, including occupational hazards encountered by the invasive cardiologist, are discussed. We also address the mechanisms of pain generation in the spine and the role that inflammation plays, which explains the presence of symptoms with little or no detectable pathology on imaging studies.

“…Two other studies testing subjects in similar postures have however found statistically significant effects of vibration, although the experimental conditions again differed and in both cases the subjects were sitting upright without the support of a backrest. Sullivan and McGill (1990) tested five male subjects who were exposed to 5 Hz 2.0ms-' peak vibration for 30 minutes, and Magnusson et al (1990) tested 12 female subjects under 5 Hz 1 .Omi' r~s amplitude vibration but for a shorter period of 5 minutes. The mean spinal shrinkages recorded in the two studies were 9.0mm and 5.9mm respectively.…”

Stadiometer Measurements of Driver'S Spinal Response to Steering Force and Vibration

The effects on spinal loading of two aspects of the driving task - force exertion while steering and exposure to 4 Hz 1ms−2 peak vertical seat vibration - were investigated with a group of six male subjects seated in a driving simulator. In addition, the effect of the combination of the two aspects was tested. Spinal shrinkage was measured with a precision seated stadiometer over a 40 minute period. Analysis of variance showed that both steering actions and vibration had a significant effect on spinal loading (p<0.05 and p<0.025 respectively), even though the steering torque (5Nm) was moderate. The response was significantly greater in all three experimental conditions than in static sitting (in the same posture). There appeared to be a tendency for the mean spinal shrinkage to increase from 6.0 mm when steering to 7.1mm under vibration and 8.7mm when steering and vibration were combined, but the only difference which was statistical significant was that between the combined condition and steering alone (t test, p<0.01).

“…It has shown that vibration of the vehicle results, in many cases, in low back swelling (bigger than among average man) in dyscopathy and backache [6]. It has been observed that diversion of the support results in the increase or decrease of the driver's height [6][7][8][9]. Some of the research verifying this observation were different from earlier conclusions.…”

The work presents the research on the influence of driver's working environment on thermical changes in their organism. The experiment was conducted between 24 and 31 March 2008 in the tram depot of Public Transport Agency in Tychy. Thermo-visual photos were conducted twice a day -before starting work and after finishing it during six following days. The group consisted of 14 drivers aged 24-49 driving city buses (the make: Solaris Urbino 18). The results were analyzed concerning statistics using Statistica. For the sake of the analysis the significance level was p = 0.05, the non-parametric Wilcoxon test or parametric T -test were used for two groups of dependent variables. The research and analysis show that driver's working environment has valid influence on thermical changes in their organism.
