Impact of nurse-assisted patient turning at different sleep stages on the quality of subsequent sleep.
Annu Int Conf IEEE Eng Med Biol Soc

Background: Nursing care performed during sleep, including nurse-assisted patient turning, is one of the factors that deteriorates sleep quality but is necessary for pressure ulcer prevention. Thus, it is important to determine when nurseassisted patient turning has the least impact on sleep quality.
Aim: The aim of this study was to clarify the impact of nurseassisted patient turning at different sleep stages and to determine the optimal timing of this aspect during sleep.
Excessive pressure and shear stress while walking cause a risk of callus formation, which eventually causes foot ulcers in patients with diabetes mellitus. Callus under the second metatarsal head (MTH) has been associated with increased shear stress/pressure ratios (SPR). Callus under the fifth MTH has been associated with increased peak shear stress (PSS).

- - This study investigates the impact of rocker sole shoes on reducing callus formation under the first metatarsal head (MTH), which contributes to diabetic foot ulcers, by comparing them to normal sole shoes.
- - Measurements were taken on healthy participants to analyze external forces (like peak pressure and shear stress) and leg motions while walking in both types of shoes.
- - Results showed that rocker sole shoes significantly lowered the shear stress-pressure ratio (SPR-i) under the first MTH, potentially reducing the likelihood of callus formation compared to normal sole shoes.
