 An evaluation of arm function and its connection to sitting posture was reviewed as a preliminary study to develop a usable evaluation for wheelchair users. We explored the effects of sitting posture on arm coordination in ten healthy subjects on a drawing test utilizing four different sitting positions. Main outcome measures were description time, handwriting area and sitting COP movement. Significant differences in handwriting ability could be attributed to differences between stable and half-sitting positions. With the three different sitting positions, our analysis showed significant correlations between description time and handwriting area, description time and sitting COP movement, and handwriting area and sitting COP movement. The results showed that posture control significantly affected arm coordination. Thus, this drawing test is useful for the quantitative evaluation of coordinated relationship between arm function and other body parts.
