Abstract
Sitting for prolonged periods of time increases seating interface pressures, which is known to increase the risk of developing pressure ulcers. Those at risk of developing pressure ulcers are advised to perform pressure relieving movements such as “pushups” or “forward leans” in order to reduce the duration and magnitude of pressure acting on the vulnerable ischial tuberosity region. The aim of this review was to synthesize and critique the existing literature investigating the effectiveness of pressure relieving movements on seating interface pressures. The twenty-seven articles included in this paper highlight the need for further research investigating the effect of recommended pressure relieving movements on the pressures around the ischial tuberosities. Furthermore, this review found that the majority of individuals at risk of developing pressure ulcers do not adhere with the pressure relieving frequency or magnitude of movements currently recommended, indicating a need for pressure ulcer prevention to be explored further.
Highlights
Sitting for prolonged periods of time is thought to increase the risk of developing pressure ulcers [1, 2]
Sitting forces the weight of an individual against the supporting seat surface which compresses the so tissues around the buttock area between the chair and the bony ischial tuberosities. is pressure causes an obstruction of blood ow that when combined with limited movement, poor sensation, malnutrition, and increased age can eventually lead to ulceration [3,4,5]. ese severe, yet usually preventable wounds are relatively common, spanning acute, rehabilitation, and community settings [6, 7], as such, the treatment of pressure ulcers is considered to outweigh the social and nancial costs associated with prevention [7]
Moes [27] explored the relationships between interface pressure, pelvic rotation, and body characteristics of 19 ablebodied participants. rough multiple regression techniques it was shown that intrinsic characteristics including ectomorphic index, gender, mass, and the body anthropometry greatly affected pressures at the seating interface during forward and backward rotations of the pelvis
Summary
Sitting for prolonged periods of time is thought to increase the risk of developing pressure ulcers [1, 2]. One of the most effective preventative methods in terms of cost and pressure relief is regular repositioning [8]. Individuals at risk of developing pressure ulcers are taught and encouraged to perform regular repositioning movements in order to redistribute the build-up of pressure around the ischial tuberosity and sacral regions. The evidence that these pressure relieving movements effectively redistribute pressures between the individual and the seating surface, known as seating interface, has not been explored.
