摘要: The aim of this study was to investigate if participants with pain experience reduced development when using a mouse allowing more neutral position the wrist (Anir) compared traditional mouse. population consisted 67 mean intensity approximately 50 mm on 100-mm Visual Analog Scale (VAS). total group randomly divided into 1 intervention and control group. performed as prospective parallel study. VAS used assess average level in musculoskeletal system during 6-month period. An earlier article found that after Anir for 6 months, significant reduction reported neck (48.9 33.9). Corresponding data other areas upper extremities were shoulder (54.1 31.8), forearm (52.9 32.8), hand (42.5 22.3), respectively (Aaras, Ro, & Thoresen, 1999). rep...
