One primary concern for the aging population is the risk of developing pressure ulcers (PU). PU are any localized sore‚ wound or injury to the skin and/or underlying tissue usually located over a bony prominence. Tayyib et al. suggests that maneuverability is a natural defense to lessen or shorten continuous pressure on the skin (2015). Extended external pressure is the most frequently considered stress factor in the development of PU. The prevention and management of PU in both hospitals and community
