%X 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 ˇ°pushupsˇ± or ˇ°forward leansˇ± 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. 1. Introduction 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 soft tissues around the buttock area between the chair and the bony ischial tuberosities. This pressure causes an obstruction of blood flow that when combined with limited movement, poor sensation, malnutrition, and increased age can eventually lead to ulceration [3¨C5]. These 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 financial costs associated with prevention [7]. One of the most effective preventative methods in terms of cost and pressure relief is regular repositioning [8]. Within rehabilitation, 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. These repositioning movements include vertical pushups, lateral and forward leans. Occupational therapists being responsible for seating and postural care are ideally placed to educate the individual and their carers on good skin health and the importance of relieving pressure at the seating interface regularly [9]. Currently, individuals ˇ°at riskˇ± are advised to change their posture by performing pressure relieving movements as often as
