Document Summary
Falls in older adults (intrinsic and extrinsic factors) Given the changes taking place as we age, how would you choose to move through an open environment. A steady increase in the average lifespan of human. Life expectancy in 1900 is 47 years. Now its 77 years due to: health care, disease reduction, lifestyle awareness. Motor behaviour is a product of interacting constraints: environment, task. Ageing and task - nature of task will determine whether an older adult is capable of success: dif culty, duration, fast, accurate. Environment will also determine success: temperature, lighting, surface, familiarity with surroundings. Gradual, time-related biological process that takes place as degenerative processes overtake regenerative processes. Grey matter (follows a gradual linear decline in volume with age, volume loss is attributable to shrinkage of neurons) White matter (declines more rapidly during mid-adulthood and affects speed information processing) A loss of stratal dopamine receptor binding. Reduction in episodic memory, executive function and motor performance.
