Description
The purpose was to investigate the cause of the increased horizontal force applied to the buttocks in the fully reclined position of back support on a reclining wheelchair with a rotational axis of back support which was located at the same position as the greater trochanter. The subjects were 15 healthy adult men. The forces were measured using a force plate on the experimental chair. And, we measured the trunk sliding distance along the back support. A comfortable sitting posture in the chair was selected for measurement. Under the rear-axis condition, the rotational axis of the back support was located at the point farthest back in the seat. Under the trochanter-axis condition, the rotational axis was located at the same position as the greater trochanter. In the fully reclined position, the horizontal forces under the rear-axis and trochanter-axis condition were 9.4 ± 1.2 and 15.6 ± 1.7% Body Weight, respectively ( p < 0.01), and the trunk sliding distances were 71.3 ± 10.6 and − 1.3 ± 7.4mm, respectively ( p < 0.01). These results suggested that the horizontal forces applied to the buttocks were changed by the trunk sliding along the back support in the fully reclined position.
