Researchers say that while there were no significant differences between the two groups in stride length and step velocity, members in the comparison group those without a known neurological impairment significantly increased the time they spent stabilizing on two feet from the low load Guess Bag Pink Flowers
Multitasking Adds to Parkinson's Fall Risk
Researchers at Florida State University say Parkinson's disease alters gait, stride length, and step velocity. It also alters the ability of older people to stabilize themselves on both feet when asked to perform increasingly difficult verbal tasks while walking.
Injurious falls accounted for 2.1 million emergency room visits by adults over 65 in a recent calendar year. People between 75 and 84 accounted for 40.3% of the visits, followed by those over 85 at 32.4% and 27.3% for people 65 to 74.
says in a news release.
Risks of Walking and Talking"Perhaps one of the most common dual tasks that we perform is talking while walking," the researchers write. "In isolation, neither task would be considered difficult to perform, yet when coupled, the relative ease of each task may change."
The findings of the study "highlight the importance of efforts to reduce falls and illuminate how injurious falls contribute to human suffering, [emergency department] overcrowding, hospital costs and admission to long term care facilities."
This seems to be particularly true for people with Parkinson's disease and even for older people who do not suffer from a neurological disorder, the researchers say.
All participants were asked to walk while counting by ones, a low load task. They also were instructed to perform a mid level task: serial subtraction by threes. The participants also were given a high load task that asked them to recite an alpha numeric sequence, such as D 7, E 8, F 9, and so forth.
The researchers used a portable walkway system, a 14 foot mat containing 13,824 sensors that measured, interpreted, and recorded gait data as participants walked on it.

Simply put, older people with Parkinson's shouldn't give directions or be asked to provide a thoughtful response to a complicated question when they are walking, the researchers say.
Parkinson's and FallsResearchers signed up 25 people with Parkinson's 19 men and six women to take part in the study. Their ages ranged from 41 to 91. The researchers then asked 13 people in the same age and education range but without a history of neurological impairment to walk and talk at the same time.
to the high load tasks.
"These results suggest that it might be prudent for health care professionals and caregivers to alter expectations and monitor cognitive linguistic demands placed on these individuals while they are walking, particularly during increased risk situations, such as descending stairs, in low light conditions, or avoiding obstructions," study researcher Charles G.

Sept. 30, 2010 Older adults with Parkinson's disease as well as those without neurological problems are at increased Gold Prada Handbag risk of injury causing falls when walking and talking at the same time, a study shows.
A surprising finding of the study was that even older adults who do not have a neurological impairment also have trouble walking Rolex Oyster Perpetual Datejust 41
