Meta-analysis of type and complexity of a secondary task during walking on the prediction of elderly falls.
Summary of "Meta-analysis of type and complexity of a secondary task during walking on the prediction of elderly falls."
Aim:â€ƒ Dual-tasking probes divided attention and causes performance changes that are associated with an increased risk for falls in the elderly. There is no systematic review investigating the effect of task type and complexity on the prediction of elderly falls. This article synthesizes research evidence regarding this issue on the contents of dual-tasking walking. Methods:â€ƒ Relevant studies were systematically identified from electronic databases of Medline, PubMed, CINAHL, Cochrane CENTRAL and PsycINFO, and the reference lists of identified articles. The selection criteria were defined a priori. Two independent reviewers classified task types based on properties for cognitive demand, assessed the methodological quality with a customized checklist, and calculated the odds ratio of fall prediction. Results:â€ƒ There was one study of reaction time, one of discrimination and decision-making, 10 of mental tracking, three of verbal fluency and five of manual tasks. The methodological heterogeneity was manifested in the selection criteria, faller classification, tasks and measures, resulting in substantial heterogeneity (I(2) 87-92%). Meta-analyses resulted in a significant pooled odds ratio 1.33 (95% CI 1.18-1.50). The mental tracking task was the only type that yielded a significant odds ratio 3.30 (95% CI 2.00-5.44). Running meta-analyses separately for simple and difficult mental tracking task showed similar odds ratios. Conclusion:â€ƒ The mental tracking task yielded significant dual-task-related changes for fall prediction. Most studies successively used an appropriate level of task complexity specific to the specified population of interest. More research is required for definite conclusions regarding the effect of task type and complexity. Geriatr Gerontol Int 2012; â€¢â€¢: â€¢â€¢-â€¢â€¢.

Medical and Biotech [MESH] Definitions
Works consisting of studies using a quantitative method of combining the results of independent studies (usually drawn from the published literature) and synthesizing summaries and conclusions which may be used to evaluate therapeutic effectiveness, plan new studies, etc. It is often an overview of clinical trials. It is usually called a meta-analysis by the author or sponsoring body and should be differentiated from reviews of literature.
Time And Motion Studies
The observation and analysis of movements in a task with an emphasis on the amount of time required to perform the task.
An activity in which the body advances at a slow to moderate pace by moving the feet in a coordinated fashion. This includes recreational walking, walking for fitness, and competitive race-walking.
Task Performance And Analysis
The detailed examination of observable activity or behavior associated with the execution or completion of a required function or unit of work.
Meta-analysis As Topic
A quantitative method of combining the results of independent studies (usually drawn from the published literature) and synthesizing summaries and conclusions which may be used to evaluate therapeutic effectiveness, plan new studies, etc., with application chiefly in the areas of research and medicine.
Dual-task methodology has been increasingly used to assess cognitive motor interference while walking. However, whether the observed dual-task-related gait changes are systematically related to method...
Background: Turning is the most important trigger for freezing of gait (FOG) in Parkinson's disease (PD), and dual-tasking has been suggested to influence FOG as well. Objective: To understand the eff...
ABSTRACT: BACKGROUND: Meta-analysis methods exist for combining multiple microarray datasets. However, there are a wide range of issues associated with microarray meta-analysis and a limited ability t...
Walking is a complex motor task generally performed automatically by older adults. Falls with or without serious consequences such as fractures or fear of falling can be the result. Gait analysis show...
The aim of this study was to determine how and whether changes in the primary motor cortex (M1) are affected by dual motor task. We further investigated how dual motor task is dependent on task proper...
Objective: The investigators aim to evaluate the impact of a " limitations " section in systematic review's abstract on results' interpretation by readers. Design: Randomized ratio 1:1 c...
To use the meta-analytic approach to examine the effects of aerobic exercise on resting systolic and diastolic blood pressure in children.
The purpose of the study is to evaluate the impact of an exercise programme organized into supervised walking groups on metabolic control, functional capacity and overall quantity of physi...
The primary purpose of this investigation is to determine the predictive value of task persistence as measured by a mirror tracing task. A secondary purpose is to evaluate differences in...
For over 60 years the most appropriate oxygen level for preterm babies remains unknown. To answer this, we will combine data from over 5300 babies to be sure the expected benefits of lower...
