ABSTRACT
<p><b>OBJECTIVE</b>To investigate the relationship between backrest thickness and lumbar muscle fatigue so as to confirm the fitting backrest thickness.</p><p><b>METHOD</b>Twenty subjects coming from university seated at a computer workstation in three backrest thicknesses: 4, 7 and 10 cm. The time that the subjects reported the lumbar muscle fatigue was collected during each trial and subjective appraise was collected at the end of the entire protocol.</p><p><b>RESULTS</b>The MF value decreased and lumbar muscle felt fatigue in all three backrest thickness. Subject could feel fatigue more late [(45.0 +/- 10.8) min] and subject felt more comfort at 7 cm thickness.</p><p><b>CONCLUSION</b>It is better to relive computer worker lumbar muscle fatigue when the backrest thickness was kept on 7 cm. Work break was needed because one hour work could cause muscle fatigue.</p>
