Our multi-year study aims to better understand how patient room design can increase stability during ambulation, serving as a fall protection strategy for frail and/or elderly patients. The aim of this portion of the study was to ascertain the architect’s perspective on designing a room to mitigate the risk of falls, as well as to evaluate the face validity of a predictive algorithm to assess risk in room design using the input of a design advisory council (AC). The purpose of this paper is to provide insight into the design process and decision-making for patient rooms; summarize the impressions of industry experts about the configurations and layout of the patient rooms tested in a preliminary augmented reality model; establish the face validity of modeled heat maps depicting risk; and report the results of a pre-meeting and post-meeting survey of e...

Many studies have been done over the last few decades in an attempt to better understand how to prevent falls among the elderly population. Unfortunately, most of these studies are conducted by simulating falls in a laboratory with healthy adults which has been shown to be quite different from a real world fall. This pilot study defines corrective behaviors implemented by the elderly to maintain balance and looks specifically at measures of stability when the hand touch corrective behavior is used. These measures include base of support area, proximity of center of mass to base of support perimeter, time for center of mass to contact base of support perimeter, and jerk of the center of mass of the torso. Initial findings indicate that the hand touch corrective behavior is used to both maintain and regain stability. It is anticipated that, with the evaluation o...

In this study we evaluate the unrestricted, natural pattern of movement of the STW task from a hospital bed of 21 (5 Female, 16 Male) frail (MFS > 55) adults (68.0±11.2 years) with a total of 144 unique trials. Bed height (low, medium, high) and bed rail condition (no rails, Hill-Rom®, Stryker®), were varied, generating 9 potential trial types per participant. A new STW phase, Stand Preparation, is defined specifically for the frail that occurs just prior to the Flexion Momentum Phase, also named here as the Stand Initiation Phase. In conjunction with the newly defined Stand Preparation Phase, movements used by the frail to maintain or regain balance during STW task are newly defined as corrective behaviors (CBs). These include hand, foot, leg and torso CBs. In 144 unique STW trials, 678 hand and foot CBs were observed and recorded. The most frequent CB ...
