Explain the effects of old age and disease on movement.

Answer 1

Old age can lead to a number of physical changes that affect movement, including declines in muscle strength, flexibility, and balance. Bones become more brittle and prone to fracture, and joints may become stiff and painful, making mobility more difficult. Additionally, changes in vision, hearing, and cognitive function can affect an individual's ability to navigate their environment and react to hazards.

Diseases can also have a significant impact on movement. Conditions such as arthritis, Parkinson's disease, multiple sclerosis, and stroke can cause muscle weakness, tremors, balance problems, and other movement impairments. Additionally, chronic pain and fatigue can limit mobility and contribute to an overall decline in physical function. In some cases, if left untreated or unmanaged, certain diseases can lead to permanent disabilities and severely limit an individual's ability to move and perform daily activities.
