Evidence-Based Evaluation of Staircase Architectural Design to Reduce the Risk of Falling for Older Adults

The impact of an increasingly aging population warrants accommodations in home architectural design. Focusing on the staircase design criteria as part of the home environment, this article presents an integrated evidence-based staircase evaluation for home staircase design to reduce the risk of falling for older adults (those 65 years and older). The staircase evaluation has been developed by dividing the staircase into four design elements: handrail design, step design, staircase geometric design, and lighting. Each element is divided into several features that define its architectural design. For example, the step design element is further divided into four features: going depth, riser height, nosing, and step finishing material. A hierarchical list is provided based on an evidence-based comparison of various scenarios for each feature. The hierarchical list presents the comparative effect of each scenario on reducing the risk of falling for older adults.
