“…The majority of a teacher's time is spent standing in the classroom, walking while teaching, writing on the blackboard, preparing lessons, grading assignments, and doing other administrative tasks with risky working postures for extended periods, all of which stress the musculoskeletal system and development of LBP [ 27 , 28 ]. In Africa, almost all teaching activities are performed under unfavorable conditions, requiring teachers to use their physical, cognitive, and effective capabilities to achieve a teaching objective while over-demanding or generating effort for their psycho-physiological functions [ 29 ]. Psychosocial factors such as high workload, sleep disturbance, low job satisfaction, and job stress have been implicated as risk factors for LBP among school teachers [ 25 , 30 – 32 ], while some factors like regular exercise and good job satisfaction act as protective effects against LBP in teachers [ 30 , 33 ].…”

Introduction Low back pain (LBP) is a key social, economic, and public health problem in the world. The impact of LBP is given less priority and is empirically unrepresented in low- and middle-income countries as a result of the focus on more pressing and life-threatening health issues, including infectious diseases. In Africa, the prevalence of LBP is irregular and increasing among schoolteachers on account of teaching activities performed under suboptimal working conditions. Therefore, the objective of this review was to estimate the pooled prevalence and associated factors of LBP among school teachers in Africa. Methods This systematic review and meta-analysis was designed based on the PRISMA guidelines. A comprehensive systematic literature search focused on LBP in African school teachers was conducted using the PubMed/MEDLINE, CINAHL, and CABI databases, regardless of publication timelines, from October 20 to December 3, 2022. In addition, gray literature was searched using Google Scholar and Google Search. Data were extracted in Microsoft Excel by using the JBI data extraction checklist. The overall effect of LBP was estimated using a random effect model via DerSimonian-Laird weights. The pooled prevalence and odds ratio of associated factors with 95% CI were computed using STATA 14/SE software. The I2 test and Egger’s regression test were used to assess heterogeneity and publication bias, respectively. Results A total of 585 articles were retrieved, and 11 eligible studies involving a total of 5,805 school teachers were included in this systematic review and meta-analysis. The overall estimated pooled prevalence of LBP in African school teachers was found to be 59.0% (95% CI: 52.0%–65.0%). Being female [POR: 1.53; 95% CI (1.19, 1.98)], being older [POR: 1.58; 95% CI (1.04, 2.40)], being physically inactive [POR: 1.92; 95% CI (1.04, 3.52)], having sleep problems [POR: 2.03; 95% CI (1.19, 3.44)] and having a history of injury [POR: 1.92; 95% CI (1.67, 2.21)] were factors significantly associated with LBP. Conclusions The pooled prevalence of LBP was high among school teachers in Africa compared to developed nations. Sex (female), older age, physical inactivity, sleep problems, and a history of previous injury were predictors of LBP. It is suggested that policymakers and administrators ought to gain awareness of LBP and its risk factors to put existing LBP preventive and control measures into action. Prophylactic management and therapeutic strategies for people with LBP should also be endorsed.

“…Several studies of high prevalence in musculoskeletal disorders among different professionals in Abeokuta metropolis have been researched and reported by the author [3], [5,6]. Due to incessant accident and complain of absence from work couple with pains by the commercial motorcyclist, this present research was aimed and designed to investigate the cumulative trauma disorders among the commercial motorcyclist leading to discomforts and related hazards and survey the model of motorcycle used in Abeokuta, Ogun State.…”

Motorcycles have become a mean of transportation in our rural and urban area in Nigeria. This cross sectional study was conducted in Abeokuta Ogun State to assess the work-related musculoskeletal disorders (WRMSDs) among the motorcyclist between October 2021 and January 2022 using snowball techniques. A structured modified Nordic Musculoskeletal disorder questionnaire (SNMQ) was administered to four hundred and fifty (450) motorcyclists. The result shows that 91.6% (412) of the motorcyclist participated. Furthermore, 76.1% of the cyclist experienced daily pains and 81.6% reported major pains in body parts. However, the results also show that major affected body regions were lower back (81.6%), leg (61.2%), upper back (82.0%), shoulder (55.1%), neck (82.5%), knee (73.3%), wrist/hand (98.8%), thigh (91.3%), ankle/feet (78.9%), ears (80.3%), eyes (59.0%), head (63.1%) respectively. The study concluded that high prevalence of WRMSDs existed among the commercial motorcyclists as a result of working hours, sitting posture, smoking and alcoholic drinking. Reduction of these symptoms could be achieved through the reduction of working hours.

“…MSDs are part of the occupational health problems in waste industries in developing countries [4][5]. The posture of a human body at work is influenced by several factors, including workstation layout (height of the workplace, the orientation of tools and work objects), hand tools design, work methods, and work habits, visual control and force exertion requirements and characteristics of the workers [5][6]. Poor and un-natural working posture have been associated with the onset of fatigue, body discomfort, pains and musculoskeletal disorders [5,7].…”

Working posture or work attitude is the working position is naturally formed by the body of workers due to the facilities used to interact with or work habits. Unsuitable working attitude can cause physical complaints such as pain in the muscles (Musculoskeletal Complain). Brick-making factories were encountered in the Village of Sail. This research is a field where once obtained the data needed and then do the processing of the data from the mapping process operations, risk evaluation work experienced by workers by using OCRA Checklist, calculate the value OCRA index, focus group discussions problems faced by workers, design repair work method proposed, calculates the data anthropometry workers, prototyping proposed workstation moulding bricks and evaluate the results of the optimization workstation moulding bricks. After all, factors rated the results of activities scored bricks have totalled a score of 23.19 for the body of the left and amounted to 25.13 to the right part of the body. This value is high because the number of ATA and RTA are very much different. If the number of recommended actions (RTA) is smaller than the number of actual action (ATA) then there is a risk assessment of musculoskeletal disorders.
