• This study was designed to investigate the effects of sitting posture on sitting pressures and electromyograms to obtain baseline data for improving seating for the elderly. The subjects were ten healthy Japanese men, and nine sitting positions were tested utilizing an experimental modular chair. Pressures on the seat and back,and surface electromyograms of the tibialis anterior,soleus,vastus medialis,superior trapezius,and iliocostalis-lumborum for each sitting position were recorded. The results were as follows: 1) Pressure on the seat was significantly increased when the seat height was high and when the armrest height was high or low. 2) Pressure on the seat was increased at a back angle of 110゜, and pressure on the back was increased at back angles of 110゜and 120゜. 3) High seat height did not place a direct burden on the soleus, but affected the posture resulting in a burden on the legs. 4) Integral electromyograms were increased significantly at a high armrest height, and it is predicted that a poor armrest fit may place a burden on the shoulders.
