There was strong evidence for one intervention category , resistance training , leading to the recommendation : Implementing a workplace-based resistance training exercise programme can help prevent and manage UEMSD and symptoms .
The synthesis also revealed moderate evidence for stretching programmes , mouse use feedback and forearm supports in preventing UEMSD or symptoms .
There was also moderate evidence for no benefit for EMG biofeedback , job stress management training , and office workstation adjustment for UEMSD and symptoms .
The burden of disabling musculoskeletal pain and injuries ( musculoskeletal disorders , MSDs ) arising from work-related causes in many workplaces remains substantial .
There is little consensus on the most appropriate interventions for MSDs .
Our objective was to up date a systematic review of workplace-based interventions for preventing and managing  upper extremity MSD ( UEMSD ) .
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
