_______ can be associated with decreased judgment as well as hypokinesis that reduces an elderly person's level of fitness in a spiral fashion.

- 1. depression
- 2. dementia/delirium
(Obj 9) risk factors for falls in older adults: name some
muscle weakness, history of falls, gait deficit, use of AD, visual defecits, neurological deficits, arthritis, impaired ADL's, depression, cognitive impairment, age>80, meds, cardiovascular deficit
(Obj 10) recommend an exercise and activity program to lessen risk of falling:
tailored to individual needs; directed towards joint and muscle flexibility, muscle strength/length, balance (static/dynamic/single leg), posture and general aerobic fitness
(obj 11) Describe the relationship between a fall and fear of falling:
a fall frequently causes a fear of falling which inhibits the amount of and level of physical activity,which reduces level of fitness.
(Obj. 12) Instructions for getting down to the floor and getting back up:
