There was low- to very low- quality evidence that other interventions were not effective in reducing work-related upper limb and neck MSDs in adults .
We found moderate- quality evidence to suggest that the use of arm support with alternative mouse may reduce the incidence of neck/shoulder MSDs , but not right upper limb MSDs .
Moreover , we found moderate- quality evidence to suggest that the incidence of neck/shoulder and right upper limb MSDs is not reduced when comparing alternative and conventional mouse with and without arm support .
However , given there were multiple comparisons made involving a number of interventions and outcomes , high- quality evidence is needed to determine the effectiveness of these interventions clearly .
While we found very-low- to low- quality evidence to suggest that other ergonomic interventions do not prevent work-related MSDs of the upper limb and neck , this was limited by the paucity and heterogeneity of available studies .
BACKGROUND Work-related upper limb and neck musculoskeletal disorders ( MSDs ) are one of the most common occupational disorders around the world .
Although ergonomic design and training are likely to reduce the risk of workers developing work-related upper limb and neck MSDs , the evidence is unclear .
OBJECTIVES To assess the effects of workplace ergonomic design or training interventions , or both , for the prevention of work-related upper limb and neck MSDs in adults .
Evaluation of Two Preventive Interventions for Reducing Musculoskeletal Complaints in Operators of Video Display Terminals
Background and Purpose The purpose of this study was to evaluate the efficacy of a preventive ergonomic intervention , which was provided by physical therapists , on spinal and upper-extremity work-related posture and symptom complaints of workers who use video display terminals ( VDT ) . Subjects Two hundred employees who spent at least 20 hours per week at a VDT were r and omly divided into 2 groups . Group E received the ergonomic intervention and an informative brochure , and group I received only the brochure . Methods Both groups were evaluated at the beginning of the study and at a follow-up 5 months later . The following tools were used : a pain drawing and the Rapid Entire Body Assessment ( REBA ) method to assess spinal and upper-extremity work-related posture . Results Group E had a lower REBA score and reduced lower back , neck , and shoulder symptoms compared with group I. Discussion and Conclusion The results suggest that a personalized preventive ergonomic intervention can improve spinal and upper-extremity work-related posture and musculoskeletal symptoms for workers who use VDTs
