Abstract
Occupational exposure to whole-body vibration is associated with the development of musculoskeletal, neurological, and other ailments. Low back pain and other spine disorders are prevalent among those exposed to whole-body vibration in occupational and military settings. Although standards for limiting exposure to whole-body vibration have been in place for decades, there is a lack of understanding of whole-body vibration-associated risks among safety and healthcare professionals. Consequently, disorders associated with whole-body vibration exposure remain prevalent in the workforce and military. The relationship between whole-body vibration and low back pain in humans has been established largely through cohort studies, for which vibration inputs that lead to symptoms are rarely, if ever, quantified. This gap in knowledge highlights the need for the development of relevant in vivo, ex vivo, and in vitro models to study such pathologies. The parameters of vibrational stimuli (eg, frequency and direction) play critical roles in such pathologies, but the specific cause-and-effect relationships between whole-body vibration and spinal pathologies remain mostly unknown. This paper provides a summary of whole-body vibration parameters; reviews in vivo, ex vivo, and in vitro models for spinal pathologies resulting from whole-body vibration; and offers suggestions to address the gaps in translating injury biomechanics data to inform clinical practice.

Metabolic Disorders and Mineral Density of the Bone Tissue in the Early Pathogenesis of Osteonecrosis: Study on Rabbits with Steroid-Induced Osteonecrosis. Bull Exp Biol Med 2021; 170:724-728. [PMID: 33893967 PMCID: PMC8065315 DOI: 10.1007/s10517-021-05141-3] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/14/2020] [Indexed: 11/07/2022]
Abstract
The relationship between the appearance of bone metabolism disorders and the onset of steroid-induced osteonecrosis remains unclear. We studied the time course of calcium, phosphorus, osteocalcin, alkaline phosphatase, and mineral density of bone tissue in the subchondral bone of the femoral head of rabbits injected with steroids and attempted to precisely determine the time when disorders in bone metabolism started in animals with steroid-induced osteonecrosis. We detected bone metabolism disorders involved in the early pathogenesis of steroid-induced osteonecrosis, which were the cause, but not the result of this condition.

Abstract
Objective — analysis of lower back pain (LBP) prevalence and risk factors for its development in employees with different conditions at their workplace, depending on their age, length of service, occupational factors, and physical activity. Material and Methods — As a result of a simultaneous cross-sectional study, 3300 employees with different conditions at their workplace were examined. To study the relationships between LBP prevalence and risk factors, we used the results of employees’ survey and physical examination, along with the data on their physical activity and working conditions. Results — The workplace posture was the most common production-related risk factor for developing LBP. The second most common risk factor was the weight of the load being lifted and carried, followed by general vibration at a workplace. The least significant factor was a bending motion. According to our data, LBP prevalence in all observation groups was increasing with both age and length of employment. Over 50% of those working in hazardous conditions at the age of 50 yo and higher had LBP. Low physical activity at a workplace led to a statistically significant increase in the chances of LBP emergence. Conclusion — In employees without exposure to harmful risk factors in the form of physical exertion and general vibration, the prevalence of LBP was significantly lower than in workers in harmful working conditions. The combined effect of static and dynamic physical activities at a workplace had a more pronounced negative impact on workers’ health. Low physical activity was a significant risk factor for LBP development.

Lv Y, Tian W, Chen D, Liu Y, Wang L, Duan F. The prevalence and associated factors of symptomatic cervical Spondylosis in Chinese adults: a community-based cross-sectional study. BMC Musculoskelet Disord 2018; 19:325. [PMID: 30205836 PMCID: PMC6134586 DOI: 10.1186/s12891-018-2234-0] [Citation(s) in RCA: 44] [Impact Index Per Article: 7.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/17/2017] [Accepted: 08/16/2018] [Indexed: 12/13/2022] Open
Abstract
BACKGROUND Cervical spondylosis adversely affects life quality for its heavy disease burden. The report on the community-based prevalence and associated factors of cervical spondylosis is rare, especially in Chinese population. Whether prevention is needed and how to prevent it is not clear. This study aims to explore its prevalence and related lifestyle factors and provide evidence on prevention of cervical spondylosis. METHODS A community-based multistage cross-sectional survey of six communities from the Chinese population was conducted. A face-to-face interview was conducted to obtain individual information, and prevalence was calculated. Single-factor analysis and multivariable logistic regressions were used to explore the associated factors in total and subgroup populations. RESULTS A total of 3859 adults were analyzed. The prevalence of cervical spondylosis was 13.76%, although it differed significantly among the urban, suburban, and rural populations (13.07%, 15.97%, and 12.25%, respectively). Moreover, it was higher in females than in males (16.51% vs 10.49%). The prevalence among different age groups had an inverted U shape. The highest prevalence was in the age group from 45 to 60 years old. The associated factors differed by subgroups. There were positive associations between engaging in mental work, high housework intensity, and sleep duration of less than 7 h/day with cervical spondylosis. Going to work on foot was a negative factor of cervical spondylosis in the total population. For people aged less than 30 years, keeping the same work posture for 1-2.9 h/day was a special related factor. Exposure to vibration was an associated factor for females aged 45-60 years. Menopause was a special related factor for women. CONCLUSIONS Prevalence of cervical spondylosis was high in Chinese population. People younger than 60 years were the focus of prevention for cervical spondylosis. Moreover, the characters between male and female and among different age groups were different and required targeted interventions.
