- Evaluating physical activity in dementia: a systematic review of outcomes to inform the development of a core outcome setPublication . Gonçalves, Ana-Carolina; Cruz, Joana; Marques, Alda; Demain, Sara; Samuel, DineshBackground: Physical activity is recommended for people living with dementia, but evidence for the positive effects of physical activity is limited by the use of heterogeneous outcomes and measurement tools. This systematic literature review aimed to summarise previously reported outcomes and identify the measurement tools used most frequently in physical activity interventions for people with dementia. Methods: Literature searches were conducted in April 2015, on Delphis and Medline. Qualitative, quantitative and mixed methods studies reporting on any type of physical activity, in any setting, across types of dementia, stages of disease progression and published from 2005 onwards were included. A content analysis approach was used to report on the frequency of reported outcomes and measurement tools. Results: The 130 included studies reported on 133 different outcome domains and 267 different measurement tools. “Functional abilities and independence” (n=69), “Global cognitive function” (n=65), “Balance” (n=43), “Global behavioural symptoms of dementia” (n=42) and “Health related quality of life” (n=40) were the most frequently reported outcome domains. “Enjoyment” was the outcome most frequently sought by patients and carers. Conclusion: The need for the development and implementation of a Core Outcome Set has been reinforced. Ahead of the completion of the Core Outcome Set, researchers and clinicians are advised to measure the impact of physical activity interventions on these frequently reported outcome domains.
- Fast gait speed and self-perceived balance as valid predictors and discriminators of independent community walking at 6 months post-stroke – a preliminary studyPublication . Rosa, Marlene; Marques, Alda; Demain, Sara; Metcalf, Cheryl D.To determine the validity of walking speed, muscle strength, function of the hemiparetic lower limb and self-perceived balance to predict and discriminate independent community walkers (ICW) within the first 6 months post-stroke.
