The purpose of this study was to examine the effect of pressure distribution according to muscle activity on trunk and lower extremity muscle with a sloping seat..
Twenty-seven males and females without lumbar muscular power problem and balance disable that influence seated position maintenance were recruited. We measured muscle activity of rectus abdominis, erecter spine, external oblique, internal oblique, rectus femoris, vastus medialis, vastus lateralis, soleus and hip pressure distribution for 20 seconds with a sloped seat for-12°, -6°, 0°, 6°, 12°. Muscle activity was used electromyography and hip pressure distribution was Foot scan..
Depending on the sloping seat muscle activity of rectus femoris, vastus medialis, vastus lateralis was a significant difference. However, according to the sloping seat the muscle activation of trunk and hip pressure distribution was no significant difference..
The muscle activation of lower extremities was found to affect the body pressure for a sloping seat.
