“…[ 3 6 15 20 ] Unlike Tunisia, the knotted carpet is the most widespread technique in several countries. According to Singh et al ,[ 6 ] knotted carpet weaving in India is based on four subtasks: “knotting,” “knot-cutting,” “beating of the knots,” and finally “the use of weaving comb.” In Iran, Mohammadpour et al ,[ 21 ] observed that the weaving task represented 78% of the time required by a handmade knotted carpet. They identified five subtasks: “pick up hook,” “see the map,” “select aigrette,” “knot,” and “cut the knot.” The highest MSD risk level was associated with “knot” and “cut the knot” sub-tasks.…”

Background: Musculoskeletal disorders are one of the most common occupational health problems and one of the leading causes of temporary disability. This study aimed to assess the biomechanical constraints of upper limb musculoskeletal disorders associated with Tunisian weavers’ tasks. Methodology: An ergonomic approach was adopted with a representative sample of Tunisian weavers. First, the activity was observed mainly for identifying tasks and sub-tasks. Then, the biomechanical constraints were assessed based on the Borg scale and the software analyses and encoding of the 2,000 images extracted from the activity video recordings. These analyses were done with the ERGOROM software. Results: Four main tasks were identified (warping of the loom, weaving itself, beating up, and finishing). As for the subtasks, the six most important were thread coiling, shedding and picking, beating up the weft, knotting, cutting, and shearing. Semi-quantitative analysis revealed that weavers spent most of their working time in the constrained neck and upper limb postures. Shoulders were in flexion/abduction during 68.6% of the activity and pinch grip was spread over 83.3% of the working time. Furthermore, elbows and wrists were highly concerned by elevated gestural variability scores. The estimated deployed strength was “medium” to “strong” in 50% to nearly 80% of cases. Conclusion: According to the results, in carpet weavers, exposure to biomechanical constraints at risk of musculoskeletal disorders was high for the various joints and parts of the upper limbs. It is, therefore, necessary to carry out interventional studies for the development of ergonomic hand tools and workstations adapted to the traditional weaver activity.

“…Currently, controlling and reducing MSDs in the workforce is one of the most important global concerns for experts in ergonomics. The importance of controlling and reducing these disorders is so high that many countries consider the prevention of work-related MSDs among the workforce as one of the national priorities [ 8 – 10 ]. According to surveys by the WHO, as well as the documentations provided by this organization in 2013, work-related MSDs are at second place of occupational diseases following occupational respiratory diseases [ 11 ].…”

Background Long-term use of computer in a static mode may cause musculoskeletal disorders (MSDs) in bank staff. Considering the high number of bank employees in different countries, such as Iran, the risk factors of these disorders should be investigated in order to implement interventions required to reduce the risk factors. This study aimed to examine the risk factors of MSDs using the Rapid Office Strain Assessment (ROSA) method and to perform an ergonomic intervention program with banking staff in Iran. Methods This interventional study was conducted on 277 bank employees in Iran. Subjects were randomly divided into three groups, including a control group (without any intervention), an educational intervention (EI) group, and a group receiving both educational and physical intervention (EPI). Before and after the intervention, the ROSA method and Nordic questionnaire were used to assess the risk factors of MSDs in office jobs and to investigate the prevalence of MSDs. Data were collected 2 weeks before and 9 months following the intervention. Results Before the intervention, the mean score of ROSA at workstations of all groups was above five with high risk. Nine months after the start of the intervention, there was a significant decrease in the mean ROSA score and its components in the two groups that received the intervention, which was statistically significant (P < 0.001). The results of the study of the prevalence of MSDs in the employees—before the intervention—indicate that the highest prevalence of MSDs in the control group was in areas of the neck (67.1%), back (64.4%), and lower back (63%). In the EI group, the highest prevalence of MSDs was in the neck (65.2%), lower back (61.6%), and back (60.7%) areas. In the EPI group, the discomfort areas were the neck (68.5%), shoulders (66.3%), and lower back (60.9%). Nine months after the intervention, there was a significant decrease in the prevalence of MSDs in the neck, shoulders, and lumbar regions of staff who received the intervention (P < 0.05). Conclusion Nine months after performing the interventions, there was a relative improvement in workstations and prevalence of MSDs in various areas within the bodies of the bank staff. This study showed that using the ROSA method is appropriate for assessing the risk factors of office work and that it can identify deficiencies in workstations. These defects can be addressed by designing and implementing an EI program together with physical interventions according to the components of the ROSA method.

“…Mohammadpour et al 8 , among other authors, signal that exposure to occupational risk factors affect mostly the meck, back, and the upper extremities. Nevertheless, through a study conducted in the year 2017 in three Spanishspeaking countries, Campos et al 7 warns that no study has evaluated the simultaneous effect of various anatomical sites in the upper extremities-an expression defined for this text as coexistence, meaning the existence of two or more concomitant MSDs or two or more MSDs simultaneously occurring in the same extremity caused, in this case, by the performance of workplace activities.…”

“…As a result, without taking into account the coexistence or concomitance of various MSDs, the direction of treatment increases the consequences for the worker while causing a delay in the worker's rehabilitation, lowers the quality of life, and generates less productivity at work 8 . This situation impoverishes workers, and it can damage entire communities to lose its most productive company workers.…”

The coexistence of musculoskeletal disorders is common in work activities around the world, however, information on the subject is insufficient both in Latin America and in Colombia despite its impact at the economic and social level. The objective of this research was to determine the coexistence of musculoskeletal disorders of work origin in the upper body in the working population that attends a Service Provider Institution (IPS). An observational, descriptive, quantitative, and cross-sectional design study was conducted between the first of March in 2017 and the first of March in 2018. Four semiological tests were applied for physiotherapists to seek the coexistence of carpal tunnel syndrome, lateral epicondylitis, rotator cuff syndrome, and cervical myofascial syndrome. Among the results, it was found that 92.6% (n=138) of the patients had two or more pathologies, 59.73% (n=89) had the rotator cuff and the myofascial syndrome, 52.35% (n=78) had epicondylitis and myofascial syndrome, and 37.58% (n=56) had carpal tunnel syndrome and lateral epicondylitis. This study highlights the high coexistence of musculoskeletal disorders in the upper body, especially in the female gender.
