However there is concern that the patient s body in the wheelchair often slides forward when they return to a seated position increasing the sitting pressure. Therefore a novel reclining wheelchair with an ergonomic V-Seat was designed to prevent forward sliding and pressure sores. The use of these reclining chairs by stroke patients has not yet been studied. Thus we investigated the effects of V-shaped and conventional seats in reclining wheelchairs on the extent of forward sliding and on the sitting pressure of stroke patients with flaccid hemiplegia and of able-bodied elders. Methods We recruited 13 able-bodied elders and 11 stroke patients with flaccid hemiplegia and performed 5 reclining cycles in both types of wheelchair. The amount of sliding along the backrest BS plane and the seat SS plane the mean sitting pressure MP and the sacral peak pressure SPP of the subjects were recorded. We used the Wilcoxon signed-rank test to compare the BS SS MP and SPP in wheelchairs with conventional and V-shaped seats and we used the Wilcoxon rank sum test to compare the differences in BS and SS between stroke patients and able-bodied elders in both types of reclining wheelchair. Results The BS SS and SPP of stroke patients were significantly lower in the wheelchairs with V-shaped seats than in conventional wheelchairs in most comparisons however the BS of able-bodied elders was higher in V-shaped seats than in conventional seats. The SS and SPP of .
