“…An estimation of physical demands by self-reports has been criticised as being inaccurate, especially for the more complex load-bearing activities carried out by employees [67]. Otherwise, it has been shown that workload and occupational physical activity can be reliably assessed by questionnaires and that questionnaires can classify groups with heterogeneous occupational tasks [68][69][70][71][72][73][74][75][76].…”

“…Although the load of whole body vibrations is considered to be associated with LBP [71][72][73], we excluded this variable because we considered this exertion as an external mechanical force and not as a result of physical activity behaviour, which was the focus of our research. It is generally agreed that the aetiology of back pain is multifactorial [74] and that physical load only partially explains the prevalence of back pain [75].…”

The objective of the study is to systematically evaluate the available evidence on the association between physical activity (i.e. occupational load and non-occupational physical activities) and low back pain (LBP). A systematic approach was used to explore the literature between 1999 and 2009. Studies were selected for inclusion following a comprehensive search of Medline, Embase and CINAHL. The methodological quality of each study was assessed. Studies were considered to be of 'high quality' if they met the cut-off criterion of 60% of the maximum available quality score. Thirty-six cohort or case-control studies were retrieved. Heavy workload and the accumulation of loads or frequency of lifts were moderate to strong risk factors for LBP. Strong associations were found for flexed, rotated and the awkward positions of the lumbar spine. Inconsistent results were found for leisure time physical activities, sports and physical exercise. Studies focusing on daily habitual physical activities (e.g. domestic activities and commuting) in association with LBP are lacking. In conclusion, the occurrence of LBP is related to the nature and intensity of the physical activities undertaken. However, physical activities can be subdivided into separate types and intensities and the ultimate physical load is the sum of all these activities. This makes it difficult to designate one particular activity as the cause of LBP.

“…Occupational drivers suffer from many musculoskeletal health problems, such as lower back pain, sciatica, lumbar vertebral early degeneration, and herniated intervertebral discs. The main etiology is thought to be vibration hazard, especially wholebody vibration 23,24) . Many researchers have found that specific vibration frequencies can cause a resonance effect with the body's vertebral system 25−27) , and this resonance energy may cause damage to the vertebral system 28) .…”

An investigation of a cluster of cervical herniated discs among container truck drivers with occupational exposure to whole‐body vibration: Fan‐Yun Lan, et al. Department of Occupational and Environmental Medicine, National Cheng Kung University Hospital, Taiwan Objective This study aimed to determine if occupational exposure to whole‐body vibration is associated with cervical intervertebral disc herniation among container truck drivers. Methods We conducted a walk‐through survey among container truck drivers and unexposed workers. We also measured the vibration hazard of the container truck over the driver's back and seat when the driver was loading a container and driving the loaded truck. Results and Discussion Among the 38 workers interviewed, 32 were container truck drivers. Four of them reported cervical herniated discs, and all of these individuals were container truck drivers with a job tenure of greater than 10 years. Self‐reported cervical herniated disc, nuchal pain, nocturia, arm/forearm weakness, arm/forearm numbness, and finger numbness were significantly more prevalent as the driver's duration of exposure increased (all p values of test for trend <0.05). The vibration of the truck during and after loading a container was considered the main cause of herniated disc. When a container truck was driven with a loaded container, both the vertical and horizontal vibrating acceleration over the seat and back sites exceeded the 8‐hr exposure level based on the ISO 2631‐1 criteria. The transient vibration dose values (VDVs) measured during misaligned or unsmooth loading operations were usually greater than the upper bounds of the health guidance caution zone for the 8‐hr VDV. Conclusions Our investigation disclosed a cluster of cervical intervertebral disc herniation that was associated with the vibration hazard during long‐term container truck driving under full load and possibly aggravated by misaligned loading operations.

“…It is reported that prevalence of back pain in full-time workers is 25.3% compared with 19.1% in part-time workers, and the prevalence of back pain is more than 23% among workers who worked over 36 hours weekly and more than 38% among workers who worked over 45 hours weekly (Eurofound, 2007). In a study of LBP among drivers, an uncomfortable working station (Alperovitch-Najenson, 2010), long career (Szeto & Lam, 2007), high daily vibration exposure (Bovenzi, 2010), annual driving mileage (Porter & Gyi, 2002) and long daily driving time, and cumulative total hours of exposure (Tiemessen et al, 2008) tended to increase the prevalence of back troubles. Moreover, the prevalence of LBP is significantly higher in those currently or previously exposed to manual material handling and/or tiring postures (20%) compared with those never exposed to these strains (11%) in men below the retirement aged 45-59 (Plouvier et al, 2011).…”

Low Back Pain

Epidemiology of LBPLBP is an important health problem in both developed and developing countries (Brooks, 2006;Woolf & Pfleger 2003). LBP results in socio-economic losses, health and clinical problems, not only for individuals but also for countries, because LBP causes obstacles to work or work absence and increases economic burden of treatment and compensation. Therefore, epidemiological study holds an important position in understanding LBP.Epidemiology is the study of the health of human populations. Its functions are:www.intechopen.com Low Back Pain 4 1. To discover the agent, host, and environmental factors which affect health, in order to provide the scientific basis for the prevention of disease and injury, and the promotion of health. 2. To determine the relative importance of causes of illness, disability, and death, in order to establish priorities for research and action. 3. To identify those sections of the population which have the greatest risk from specific causes of ill health, in order that the indicated action may be directed appropriately. 4. To evaluate the effectiveness of health programs and services in improving the health of the population. (Brownson, 1998).In the case of LBP, epidemiology investigates the various factors of LBP included in the risk factors for LBP, the effects of prevention measures and interventions on LBP, the interaction of risk factors for LBP, time course changes of LBP, the burden of LBP, associations among this information and so on. Much epidemiological research on LBP has been conducted worldwide. This research is important in understanding the past, present and future of LBP, and epidemiological data provide much information to assist in seeking and solving the various problems related to LBP. Moreover, these data can prevent LBP by avoiding or decreasing risk factors for individuals.The two most basic concepts of epidemiology are incidence and prevalence. Incidence is defined as the rate at which healthy people develop a new symptom or disease over a specified period of time. In contrast to incident, prevalence is a measure of the number of people in the population who have a symptom or disease at a particular point in time (Manchikanti, 2000). Therefore, it is necessary to note the methodological problems in the study of the epidemiology of LBP. Cunningham and Kelsey reported that back trouble is a frequent problem and the prevalence of back pain symptoms is estimated to be 17.2% from the data source of The United States (US) Health and Nutrition Examination Survey, 1971-1975 (HANES I) of the US adults aged 25-74 years (Cunningham & Kelsey, 1984). Strine and Hootman reported that from National Health Interview Survey in 2002 the prevalence of LBP increase with aging and the total prevalence of LBP only was 17.0% and the prevalence of both neck and LBP was 9.3% of US adults aged 18 years and over (Strine & Hootman, 2007 Prevalence of LBP in the general population
