Objectives: To assess Multiple Sclerosis (MS) patients' knowledge in Saudi Arabia (SA) and in which aspect of the disease do patient need more awareness. Methods: A cross-sectional web-based survey has been conducted between June and August 2017. It consisted of 2 parts: sociodemographic and 23 multiple choice questions chosen from the previously validated MS Knowledge Questionnaire (MSKQ). The survey has been sent to 500 MS patients. Results: A total of 218 MS patients filled the questionnaire where only 200 included in the study. Female MS patient represents 66% of all the participants. More than half of the patients had achieved their bachelor degree. The total mean of the correct answer for both male and female found to be 58.98%(±SD 15.06%). Most patients were aware that MS is a disease of central nervous system (93%), autoimmune disease (79%), not contagious (90.5%), or inherited (64.5%). However, few patients were aware that there is no single test to diagnose MS (28.5%), and intravenous injection of contrast during MRI reveals new lesions (18.5%). Only (37%) knew what is ''Relapsing-remitting''MS. The MS knowledge is positively correlated with the educational level. Conclusion: Patients with MS in SA have less knowledge in the disease's types, workups, and treatment efficacy. While in contrast, they have more awareness of the disease's pathophysiology. Patient's awareness programs should aid more knowledge among MS patients in SA.
The prevalence of Low back pain (LBP) is exceedingly high, upwards of 80% in the general population. LBP is manifested as pain in the thoraco-lumbar area and often related to a muscle pull. This paper is a narrative review of the mechanics of work-related low back pain. In this paper, the researchers provide a different insight of the occupational low back pain as they introduce a theoretical background of the occupational low back pain and management of low back pain at workplace. In addition, the study highlight the research focus within the field of mechanical loading and biomechanical assessment methods of low back pain. The study found that low back pain is a reversible process in case causes are identified. However, it is a challenging issue to identify the causes unless well-designed models and assessment methods are applied for each case separately.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
