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 .

Musculoskeletal, visual and psychosocial stress in VDU operators before and after multidisciplinary ergonomic interventions.
The study has a parallel group design with two intervention groups ( T and S ) and one control group ( C ) of VDU operators . Three serial interventions were carried out in the T and S groups , first a new lighting system , then new workplaces and last an optometric examination and corrections if needed . The new lighting gave significantly increased illuminance levels , increased luminances of the room surfaces and better luminance distribution . The two intervention groups reported significant improvement of the lighting conditions , as well as of the visual conditions and significantly reduced visual discomfort and glare . Significant reduction of headache was found in one of the intervention groups . Optometric corrections reduced the visual discomfort in both the intervention groups . When looking at those given new corrections , a significant reduction was found in the T group and a clear tendency was also found in the S group . The C group reported no improvements for any of these health outcomes . The workplace intervention gave the operator the possibility to support the whole forearm and h and on the table top . Before the intervention there were no significant differences between the three groups regarding shoulder pain and static trapezius electromyographic ( EMG ) load . Two years after the intervention , a significant reduction of shoulder pain was reported in the T and S groups in parallel with a significant reduction in static trapezius load , while no such reduction was found in the C group . At the same time , both static trapezius load and shoulder pain were significantly lower in the T and S groups compared with the C group . Pain in the forearm and h and showed no significant changes in any of the groups during the study period . However , there seem to be a relationship between pain in the forearm and h and and the time the operator used the mouse . The C group reported significantly higher intensity of pain and used the mouse significantly more than the S group
