Abstract
Prolonged sitting is common in wheelchair-bound individuals that can lead to pressure-related injuries, especially to tissues over the ischial tuberosities and sacrum. These areas are susceptible to pressure ulcers, which affect 2.5 million people and cause 60,000 deaths in the US every year. Off-loading seat cushions can prevent or manage these injuries by relieving and redistributing the pressure from vulnerable tissues. This study compared a novel ischio-sacral offloading (ISO) seat cushion, a bare office chair, and a retail cushion in terms of their pressure distributions within the ischio-sacral region under three sitting postures: upright, reclined, and forward leaning. 10 healthy adults (age: 34.10±13.83 years, body mass: 82.37 ±12.57 kg, and BMI: 27.26 ± 4.13 kg/m2) participated in the study. A pressure-sensitive mat was used to collect data under the ischial tuberosities and sacrum for 4 minutes of seating in each position, and for all conditions. The results showed that the ISO cushion significantly reduced the mean pressure in the ischio-sacral region in all postures compared to the bare office chair. The ISO cushion (M=9.09 kPa, SD=3.20 kPa, p
