Overweight schools bags will bring additional stress and fatigue to primary and junior secondary students. The Department of Health recommends that, as a precautionary measure, students should avoid carrying school bags which exceed 15% of their body weight for long periods of time. Around 60 per cent of Indian schoolchildren may suffer back pain by carrying schoolbags. For example, a heavy bag that’s slung over one shoulder can, over the 12 years of schooling, cause chronic back problems that linger into adulthood. Risks include muscle strain, distortion of the natural ‘S’ curve of the spine and rounding of the shoulders. The low back pain as a result of carrying of school bag by students has necessitated the attention given to the determination of limits of weight of school bag carrying by students in the school. It was however noted by that no Occupational Safety and Health organization exist regarding what constitutes the maximum acceptable or safe weight of school bag. After this observation, several researchers have worked on the subject of weight of school bag using three main approaches namely: Physiological, Psychophysical and Biomechanical. Author has applied the Fuzzy logic approaches for setting weight limit (WL) of school bag to be carried by students in school in the analysis the strengths and the weaknesses with the height are taken in to consideration. The approach may probably lead to reduce the problem of low back pain of students caused by heavy weight of school bag.

Abstract Background: MSK health is imperative for the active participation of an individual in society and MSK related disorders more direly affects a person's quality of life compared other non-communicable disease while it also negatively effects the health system and economy of a country. The current manuscript analyzed and describes the disease burden of MSK disorders in the EMRO region.Methods: This was a cross-sectional descriptive-analytical study conducted based on data published by the Global Burden of Disease Database for MSK disorders up to 2017. The study target comprised population from all countries of the EMRO region of World Health Organization. The present study considered, MSK disorders such as (rheumatoid arthritis), (osteoarthritis), (Low back pain), (neck pain), (gout) and (other Musculoskeletal disorders. The DALY index was used to measure total disease burden.Results: MSK disorders in the world and in the EMRO region was ranked 5th (4% of total disease burden) and 7th (5% of total disease burden) among all diseases in 2017, respectively. Women over 30 years of age in the EMRO region had the highest risk of MSK disorders compared to other regions and in addition, the DALY lost in EMRO region due to MSK disorders was higher in women of all age categories than men. According to the results of this study, Low back pain, Other musculoskeletal disorders and Neck pain had the highest prevalence and burden of disease in the EMRO region and the world. Bahrain, Iran, and Morocco had the highest incidence of MSK DALY score in the EMRO region, and Somalia, Djibouti, and Afghanistan had the lowest incidence of MSK disorders and DALY score, respectively.Conclusion: With the increase in geriatric population and obesity especially in developing countries, consequently, more people tend to suffer from MSK disorders and it is predicted that this spike will continue in the coming decades. Taking in to account the high prevalence and burden of MSK disorders, forces government and health-policy makers to focus more on preventive cares and rehabilitation.

Introduction. The nurses who works at Intensive Care Unit (ICU) and Emergency Unit often suffering Low Back Pain (LBP) because they have high mobility and unergonomic condition. The purpose of this study were to identify the correlation among age, body mass index and working position of nurses with the low back pain who work in ICU and emergency unit at Sari Mutiara Indonesia general hospital. Methods. The data obtained was analyzed by analytic correlational with cross-sectional approach. The Sampel of this study was recruited with total sampling as 31 nurses. The data was analyzed by spearman correlation with α = 0.05. Result. The result of this study found that there was a signifi cant correlation between age with low back pain (r = 0.466 ; p <0.05). While body mass index and working position there was no signifi cantly correlation with low back pain ( r=0.195; p > 0.05 and r = - 0.172;p >0.05), respectively. Discussion. It can be recommended to occupational safety team to organize training the manner of working according to ergonomic standard, in addition to develope standar operating procedure for nurses in the hospital.Keywords : Risk factors, low back pain, nurse

The Impact

Background: Work related musculoskeletal disorders are a common cause of pain in female workers in brick manufacturing industries involved in sorting and stacking process. Objective: This  study aims to categorize the component of neuropathic and/or nociceptive pain with reference to chronic low back pain, its probable causes and its impact on functional variables like hand grip strength, number of man days lost etc. Methods: Female subjects [n=220] in the age range of 28-45 years from different brick fields of Hooghly and Birbhum district of West Bengal ,India with a work experience of more than 10 years participated in this study. Pain categorization was done by PAIN DETECT TOOL .Hand Grip dynamometry done to evaluate grip strength. NIOSH equation was used to standardize RWL. Results: It showed that pain/discomfort was mainly at the low back(90%),neck(72%) and wrist(62%).72% of workers had a pain of >20 in the pain scale of the pain detect tool & 80% of workers were not satisfied with treatments with analgesics/antipyretics which indicate the involvement of neuropathic component of pain in them. The impact of pain was revealed on functional and productivity endpoints like reduced grip strength which also lead to absenteeism, loss of average man days[4.5/month] , injuries[in 33% of workers] and monotony[85% workers] Conclusion: The probable cause of the chronic low back pain may be due to radiculopathy from repetitive lifting of bricks over and above the Recommended Weight Limit [Lifting Index 1.8].DOI: http://dx.doi.org/10.3126/ijosh.v2i2.6597 International Journal of Occupational Safety and Health, Vol 2.

The World Health Organization Disability Assessment Schedule 2.0 (WHODAS 2.0) is considered by the World Health Organization (WHO) to be a useful tool for assessing the functioning and disability of the general population as well as the effectiveness of the applied interventions. Until this study, no data regarding the validity of the 36-item WHODAS 2.0 in chronic low back pain (LBP) in Poland have been explored. This study was conducted on 92 patients suffering from chronic LBP admitted to the rehabilitation ward. The Polish version of the 36-item WHODAS 2.0, the Sf-36 Health Survey (SF-36), the Oswestry Disability Index (ODI), the Hospital Anxiety and Depression Scale (HADS) and the Visual Analogue Scale (VAS) questionnaires were applied to assess patients. The scale score reliability of the entire tool for the study population was very high. The Cronbach’s alpha test result for the entire scale was 0.92. For the overall result of the WHODAS 2.0, the Intraclass Correlation Coefficient (ICC1,2) was 0.928, which confirmed that the scale was consistent over time. The total result and the vast majority of domains of the 36-item WHODAS 2.0 correlated negatively with domains of the SF-36 questionnaire; thus, a higher WHODAS 2.0 score was associated with a lower score on the SF-36 questionnaire. We found that the minimal clinically important difference (MCID) for the total WHODAS 2.0 score in patients after rehabilitation for LBP was 4.87. Overall, the results indicated that the Polish version of the 36-item WHODAS is suitable for assessing health and disability status in patients with LBP.

BACKGROUND: The World Health Organization states that low back pain is the leading cause for disability worldwide. Patients with chronic low back pain (CLBP) show important decreases in lumbar strength and can now be assessed by using the new isokinetic dynamometer BioniX Sim3 Pro which offers very detailed measurements. OBJECTIVE: To compare lumbar flexion and extension strength values, as well as extension-flexion ratio (EFR) based on isokinetic velocity and gender, for patients with CLBP on the BioniX Sim3 Pro. METHODS: A retrospective analysis was performed on data from 20 men and 22 women with CLBP. Maximum torque in flexion and extension was measured isometrically and isokinetically. Statistical analysis was performed on these parameters. RESULTS: EFR shows a downward trend with increasing speed of measurement (isometric to isokinetic 30∘/s and isokinetic 30∘/s to isokinetic 90∘/s, respectively): in men from 1.21 to 1.04 (p< 0.001) and from 1.04 to 0.93 (p= 0.207). In women, EFR decreased from 1.41 to 1.13 (p< 0.001) and from 1.13 to 1.00 (p= 0.144). CONCLUSIONS: Patients with CLBP have a decreased strength in lumbar extension and flexion compared to the age-corrected normal values of Bionix Sim3 Pro. With increasing speed of testing protocol, a decrease in EFR is observed in this population.
