-
Immobility
- may be temporary, partial or permanent
- factors that alter mobility:
- disease or trauma
- imposed immobility
- voluntary
EVERY body system is affected
-
Physiologic affects of exercise on the Cardiovascular system
- increased oxygen demand
- increased heart rate
- increased blood pressure
- increase circulation of fibromyosin
-
Immobility on CV
- increased cardiac workload
- predisposition to thrombi
- increased rate of coagulation(clot faster)
- increased in orthostatic hypotension
- dependent edema(fluid edema)
-
Affects of exercise on respiratory system
- increased depth and rate of respiration
- increased gas exchange
- increased rate of CO2 exhaled
-
Immobility results on respiratory
- decreased rate and depth
- increased secretions(pooling in the lungs)
- atelectasis- alveoli collapse and don't expand
- hypostatic pneumonia (caused by lying, virus settles in lungs )
- respiratory acidosis(decrease PH )
-
Effects of exercise on musculoskeletal system
- increased muscle mass, tone and strength
- increased joint mobility
-
immobility on MSK
- atrophy(3% loss of strength per day)
- contractures(foot drop)
- ankylosis(fixation /immobilization of joint)
- disuse osteoporosis (no wt. bearing)
-
Effects of exercise on metabolic rate
- increases metabolic rate
- burn more calories
-
immobility results on metabolic changes
- decreased oxygen demand
- decreased appetite
- negative nitrogen balance (muscle wasting catabolism)
- CAUTION: fever and trauma may increase metabolic demand
-
Effects of exercise on GI system
- increased appetite
- increased intestinal tone
-
immobility results GI
- appetite disturbances
- altered protein metabolism (protein in urine)
- poor digestion(naseau)
- slowed peristalsis(constipation, bowel obstruction, paralytic ileus-portion of ilium not functioning) ....common after surgery
-
Effects of exercise : Urinary system
- increased blood circulation
- increased blood flow to kidneys
-
immobility : Urinary
- urinary stasis(urine is not passing as fast--infection can settle)
- increased risk of bacterial growth
- predisposition to stone(calculus) formation (renal calculi)
- incontinence (urinary retention)
