EFFECTS OF AN ELECTRONIC HEIGHT-ADJUSTABLE WORKSURFACE ON COMPUTER WORKER MUSCULOSKELETAL DISCOMFORT AND PRODUCTIVITY

摘要

Thirty three computer workers from two companies worked at fixed-height worksurfaces (FHWs) and then at electronic height-adjustable worksurfaces (EHAWs) for 4-6 weeks. Subjects completed survey questionnaires before and after using the EHAWs. Results showed significant decreases in the severity of musculoskeletal discomfort for most upper body segments. In the EHAW condition daily discomfort ratings were lower in the afternoon and productivity ratings improved. There was a strong preference for using the EHAWs. An attempt to assess any placebo effect met with limited success. Further studies are needed.
