Falls experienced by people with stroke living in the community
Falls experienced by people with stroke living in the community
The frequency and circumstances of falls were identified through a literature review and a cross-sectional observational study. The study highlighted that 50% of that sample experienced falls and that repeat-fallers had significantly worse arm function and ADL ability (P,0.05) than those who did not report any instability. Largely, the findings of the circumstances study were in agreement with previous studies. However, some aspects of fall-events have not been previously identified among people with stroke, for example sideway landings, misjudgement, lack of concentration, recovery by arm movements and lack of stepping reactions. Issues surrounding balance and attention were explored in a further exploratory study. Findings highlighted that 30% of the community dwelling sample of people with stroke had sustained attention deficits, 19% presented with auditory selective attention deficits, 35% with visual selective attention deficits and 44% had divided attention deficits. Attention deficits were found to correlate with measures of balance (r=0.514, P,0.01) and function (r=0.540, P<0.01) and those who had fallen repeatedly had significantly greater attentional (P<0.01) and functional deficits (P<0.05).
In a prospective study the usefulness of a fall prediction test that simultaneously challenges motor and cognitive performance (Stops walking when talking, SWWT) was explored. SWWT was found to be a quick and simple test but predictive capabilities were only found to be moderate (sensitivity 53%, specificity 70%, positive and negative predictive value 62%) among this sample. The experimental study explored changes in balance and gait when challenged by dual tasks, comparing stroke patients and controls and people with stroke who had and had not fallen. Findings of the experiment highlighted that in comparison to controls, people with stroke experienced greater difficulties when attempting to perform two competing tasks. People with stroke demonstrated significant changes in sway (P<0.01 for ML sway) and gait parameters (P<0.01 for stride length, stride time and velocity, P<0.05 for cadence) as well as cognitive task performance (for memory during walking, P=0.017) in comparison to controls during the dual task situation.

Abstract
The frequency and circumstances of falls were identified through a literature review and a cross-sectional observational study. The study highlighted that 50% of that sample experienced falls and that repeat-fallers had significantly worse arm function and ADL ability (P,0.05) than those who did not report any instability. Largely, the findings of the circumstances study were in agreement with previous studies. However, some aspects of fall-events have not been previously identified among people with stroke, for example sideway landings, misjudgement, lack of concentration, recovery by arm movements and lack of stepping reactions. Issues surrounding balance and attention were explored in a further exploratory study. Findings highlighted that 30% of the community dwelling sample of people with stroke had sustained attention deficits, 19% presented with auditory selective attention deficits, 35% with visual selective attention deficits and 44% had divided attention deficits. Attention deficits were found to correlate with measures of balance (r=0.514, P,0.01) and function (r=0.540, P<0.01) and those who had fallen repeatedly had significantly greater attentional (P<0.01) and functional deficits (P<0.05).
