Document Summary
Declines in motor performance usually include a decrease in the ability to make decisions, along with a slowing of reaction time. Part of the latter is due to a decline in neuron signal strength. As a result, the central processing mechanisms become less efficient because they need more time to process the signals. As long as a situation does not have a time limit for the decision, older people can perform as well as when they were young. The motor system also experiences changes when it comes to mobility, where balance, posture, and gait are compromised. More than 40 per cent of canadians aged 65 or older report having at least one disability that influence, to some extent, their ability to perform activities required in daily life. The biggest problem with disabilities and other mobility deficits is that the impediments can increas a person"s risk of falling. A fall for an older person can have devastating consequences.
