“…Studies worldwide have suggested that many factors have contributed to the occurrence of RTA and mortalities among motorcyclists, which can be categorized into three main factors, namely human factor, environmental factor, and motorcycle factor [15][16][17][18]. In-depth, human factors such as fatigue, inappropriate driving, and psychological distress have been studied to be strongly associated with the occurrence of RTA [19,20]. Additionally, Michael, et al [21] demonstrated that psychological distress among motorcyclists predisposed them to inappropriate driving attitudes, particularly speeding, which predisposed them to be involved in RTA.…”

Work-related Musculoskeletal Disorders (WMSDs) are currently a matter of concern in the occupational world, where it is the leading cause of disability among workers. Food delivery riders were among the neglected workers even though they were highly exposed to the WMSDs. Thus, this study aims to quantify the magnitude of WMSDs among the riders and the impact on their work. This was a cross-sectional study involving 191 food delivery riders in Eastern Peninsular Malaysia. The Standardized Nordic Musculoskeletal Questionnaire (M-SNMQ), which was self-administered and validated for Malay translation, was used to quantify the prevalence of WMSDS based on various specific body regions. WMSD prevalence over a 12-month period was 74.9%. Upper back pain (UBP) (55.6%) and lower back pain (LBP) (73.3%) were the two most common body regions to experience WMSD symptoms. The least-complained body regions were thighs and feet, with a prevalence of 2.6% and 3.1%, respectively. The affected body regions that caused the highest daily life disturbance were the shoulders and knees, while those with shoulders symptom were more likely to be absent from work. Finally, LBP was the highest body region with at least a moderate pain score. In general, the findings should be a matter of concern among health authorities and others to improve the quality of life among the riders. To lower the prevalence of WMSDs among this understudied group, additional interventional research should be built on the findings of this study.

“…Work-related MSDs accounted for 34% of all nonfatal occupational injuries and illnesses involving days away from work in the manufacturing sector during 2017 [1]. Work-related MSDs are thought to be a result of one or a combination of risk factors, including physical risk factors (e.g., forceful exertions, repetitive tasks, awkward posture, vibration or chemical exposure), temporal aspects (e.g., work-rest scheduling and work pace), psychosocial risk factors (e.g., low job control, insufficient rest, time pressure, monotonous work, low support from management and coworkers), individual factors (e.g., age, gender, BMI, smoking), among others [2,3]. The impact of MSDs on the health of workers' is substantial and broad, and contributes to the incidence and prevalence of chronic pain, anxiety, insomnia, social dysfunction and depression [4,5].…”

Background: Musculoskeletal disorders can result from prolonged repetitive and/or forceful movements. Performance of an upper extremity high repetition high force task increases serum pro-inflammatory cytokines and upper extremity sensorimotor declines in a rat model of work-related musculoskeletal disorders. Since one of the most efficacious treatments for musculoskeletal pain is exercise, this study investigated the effectiveness of treadmill running in preventing these responses. Methods: Twenty-nine young adult female Sprague-Dawley rats were used. Nineteen were trained for 5 weeks to pull a lever bar at high force (15 min/day). Thirteen went on to perform a high repetition high force reaching and lever-pulling task for 10 weeks (10-wk HRHF; 2 h/day, 3 days/wk). From this group, five were randomly selected to undergo forced treadmill running exercise (TM) during the last 6 weeks of task performance (10-wk HRHF+TM, 1 h/day, 5 days/wk). Results were compared to 10 control rats and 6 rats that underwent 6 weeks of treadmill running following training only (TRthen-TM). Voluntary task and reflexive sensorimotor behavioral outcomes were assessed. Serum was assayed for inflammatory cytokines and corticosterone, reach limb median nerves for CD68+ macrophages and extraneural thickening, and reach limb flexor digitorum muscles and tendons for pathological changes. Results: 10-wk HRHF rats had higher serum levels of IL-1α, IL-1β and TNFα, than control rats. In the 10-wk HRHF+TM group, IL-1β and TNFα were lower, whereas IL-10 and corticosterone were higher, compared to 10-wk HRHF only rats. Unexpectedly, several voluntary task performance outcomes (grasp force, reach success, and participation) worsened in rats that underwent treadmill running, compared to untreated 10-wk HRHF rats. Examination of forelimb tissues revealed lower cellularity within the flexor digitorum epitendon but higher numbers of CD68+ macrophages within and extraneural fibrosis around median nerves in 10-wk HRHF+TM than 10-wk HRHF rats. Conclusions: Treadmill running was associated with lower systemic inflammation and moderate tendinosis, yet higher median nerve inflammation/fibrosis and worse task performance and sensorimotor behaviors. Continued loading of the injured tissues in addition to stress-related factors associated with forced running/exercise likely contributed to our findings.

“…According to the 2018 report from the Bureau of Labor Statistics, musculoskeletal disorders accounted for 34% of all nonfatal occupational injuries and illnesses involving days away from work in the manufacturing sector during 2017 [1]. MSDs are thought to be a result of one or a combination of risk factors, including physical risk factors (e.g., forceful exertions, repetitive tasks, awkward posture, vibration, heat or chemical exposure), temporal aspects (e.g., work-rest scheduling and work pace), psychosocial risk factors (e.g., low job control, insufficient rest, time pressure, monotonous work, low support from management and coworkers), and individual factors (e.g., age, gender, BMI, smoking), and more [2,3]. Musculoskeletal Heath is a Cross-Sector Council focus of the National Institute for Occupational Safety and Health (NIOSH) National Occupational Research Agenda, and musculoskeletal disorder prevention has remained a prioritized goal for the NORA Manufacturing Sector Council [4].…”

Background: Musculoskeletal disorders can result from prolonged repetitive and/or forceful movements. It has been shown that performance of highly repetitive tasks increases serum cytokines, nerve inflammation and sensorimotor declines in a rat model. This study investigated the effectiveness of flat treadmill running in preventing these responses. Methods: Thirteen young adult female Sprague-Dawley rats were trained to perform a high force task for 5 weeks (15 min/day, 5 days/week). All trained rats went on to perform a high repetition, high force reaching and lever-pulling task for 10 weeks (10-week HRHF; 2 hrs/day in four 30 min sessions, 3 days/week). Five task rats were randomly chosen to run on a flat treadmill (TM) for the last 6 weeks of task performance (10-week HRHF+TM; ramping up to 23 m/min, 1hr/day, 5 days/week). Results were compared to 10 control rats. Voluntary task and reflexive sensorimotor behavioral outcomes were assessed and compared. Serum was assayed for inflammatory cytokines, median nerves were assayed for CD68+ macrophages and extraneural thickening, flexor tendons were assayed for any pathological changes. Results: Treadmill running attenuated HRHF task-induced increases in serum TNF-alpha, IL-1beta, CXCL2/MIP2 and IL-10 levels. HRHF task-induced increases in flexor digitorum epitendon cellularity improved with treadmill running. However, several voluntary task performance outcomes, specifically voluntary grasp force, percent successful reaches, and voluntary task participation, worsened with treadmill running. The treadmill intervention failed to rescue HRHF task-induced declines in reflexive grip strength and forepaw mechanical sensitivity, and increases in CD68+ macrophages and extraneural fibrosis within and around median nerves. Conclusions: The treadmill intervention attenuated systemic inflammation and moderate tendinosis, but did not improve task performance or sensorimotor behaviors most likely because this exercise intervention continued to load involved injured forelimbs and worsened median nerve inflammation and fibrosis.
