PS1.1: Health Outcomes of Wheelchair Seated Posture in Older Veterans

We report a correlational, observational study, describing relationship of quantified wheelchair seated posture to predictors (cognitive status, supporting surfaces, sitting ability, repositioning frequency, sitting duration, independent wheelchair mobility) and outcomes (interface pressure, functional reach, pain/discomfort and Health Care Acquired Pneumonia). We included 45 Veterans over age 62 who sit in a wheelchair daily for 5 hours, for 2 hours or more.
