2. Bed rest also reffered to as the REST-CURE
,it is a medical treatement in which a person
lies in bed for most of the time to try to cure
on illness
3.
4. IMMOBILIZATION-Physical restriction of
movement to body (or) a body segment
DECONDITIONING-Decreased functional
capacity of multiple organ system
9. Forced immobility(in hospitals and nursing
home)
Inadequate aids for immobility
Poor lightening
10. Decreased mobility and
increased bed rest adversely
affect almost every system of
the body
Prolonged inactivity (or) bed rest
has adverse physical and
physiological consequences
13. Muscle: disuse atrophy “if you don’t use it
,you’ll lose it,”
loss of muscle strength ,muscle atrophy
(begins after 1 day of immobilization.1-
3%/day muscles may loss half of their bulk
after 2 months)
Bone: increased bone resorption
(Osteoporosis) increased risk of fracture,
dorsal kyphosis, and chronic back pain 1%
loss of vertebral mineral content per week)
14.
15. Immobilization can induce cartilage degeneration.
The body attempts ton repair joints through
cartilage proliferation ,osteophyte formation ,and
fibrofatty infiltration of the joint cavity.
Contractures (contributing factors include
spasticity ,improper bed positioning and
maintaining the limb in a shortened position)
Muscles ,CT that cross two joints are at increased
risk factor contractures, further impaired mobility,
resulting in more joints tightness and
contractures.
Joints stiffness and pain: if joints are not given
adequate full range of motion. The stiffness is due
to tightness of the muscles and tissues
surrounding the joints.
20. heart rate (1 beat/minute every 2 days)
1) Decreased coronary blood flow and
decreased O2 available to cardiac muscle
a) CO,SV
21. Orthostatic hypotension (begins after
3 weeks of bed rest ) due to:
Excessive pooling of blood in the
lower limb
Decreased circulating blood volume
(20 days of bed rest may lead to a 25%
of decreased STROKE VOLUME and
a 20% increased in HEART RATE).
22. Constipation
Weakening of Abdominal wall muscles
,leading to difficulty in raising the intra-
abdominal pressure sufficiently for
defecation .
Loss of privacy and embarrassment if toilet
assistance is needed.
Bowel irregularity may produce Abdominal
discomfort ,as well as cause loss of
appetite.
24. URINORY loss of:
Nitrogen-(begins day 5-6,peaks at 2
weeks)
Calcium –(begins day 2-3,peaks at 4-
6 weeks)
Phosphorus
o Reversible post mobilization
25. Decreased strength of respiratory
muscles- decreased tidal volume
,minute volume, respiratory capacity
Increased respiratory rate to
compensate for decreased
respiratory capacity
Decreased ability clear secretion
(cough reflex)
(Accumulation of secretion in the lower bronchial
tree ,which can block airways ,cause Atelectasis
and increased the risk of pneumonia)
