Week 2 Flashcards
Skeletal system changes with aging
-bone density diminishes
-bones more fragile and more likely to break (osteoporosis)
-stiffer joints
-limited range of motion
Musculature changes with aging
-muscle atrophy
-sarcopenia
-muscle fibres not able to contract as quickly
What age is peak muscle strength
-20-30
Visual changes with aging
-glaucoma
-dry eyes
-macular degeneration
-cataracts
Vestibular changes with aging
-hair cells lost affecting balance
-muscle atrophy
-earwax accumulation
-hearing loss
Proprioception with aging
-mechanoreceptor changes
-less accurate detection of body position
-increase risk of falls
Most common health condition
-hypertension
Other common health conditions
-heart disease
-asthma
-diabetes
-mood and anxiety disorders
-osteooporosis
-cancer
-peridontal disease
-osteoarthritis
-COPD
Asthma in older adults
-can sometimes decrease
Multimorbidity
-co-occurance of 2 or more common chronic diseases
Hypertension in older adults
-due to changes in vascular system
-reduction in elastic tissues, resulting in stiff arteries
When does incidence of cancer actually decrease
-after the age of 85
Most common cause of injury and death in older adults
-falls
Post fall syndrome
-creates a cycle of weakness and instability through joint mobility reductions, physical deconditioning, and poor balance
Fall cycle
-fall
-loss of balance confidence
-fear of falling again
-self restriction of physical activities
-reduced muscle strength, balance etc
-abnormal gait, more unstable
-increased risk of falling
-fall
