Additionally, individuals with post-stroke hemiplegia are at high risk for falls due to poor balance and inability to tolerate environmental challenges. We have selected specific environmental hazards by turning to the current literature related to why people fall in the home or nonclinical environment. Research has identified specific risk factors for falls in people with stroke. Fallers have shown poorer balance, lower physical function measures than non-fallers, greater standing sway, impulsivity, and slowed response times, in addition to greater postural sway and reduced force generation when standing up and sitting down. Forster and Young found that fallers were more depressed and less socially active that non-fallers. They found that most falls occurred in patients' homes while walking or during transfers. Individuals reported loss of balance, getting their foot stuck, and difficulty performing transfers as reasons why they fell. Hyndman et. al, found that repeat fallers had significantly reduced arm function and activities of daily living (ADL) ability compared with those who did not fall.
