knowledge assessment II Flashcards
body mechanics
coordinated efforts of the musculoskeletal and nervous systems
alignment and balance
also refers to posture
gravity
weight force exerted on the body
friction
force that occurs in a direction opposite to movement
decubitis
pressure ucler
decubitus
bed lying
shear
a gravity force pushing down on the patient’s body with resistance between the patient and the chair of bed
skeletal system
- provides attachments for muscles and ligaments, protects vital organs, aids in calcium regulation
- provides leverage for mobility
- bones are long, short, flat, or irregular
- joints, ligaments, tendons, cartilage
muscule movement and posture
skeletal muscles are working elements of movement
nervous system and musculoskeletal system
regulates movement and posture
mobility refers to
a person’s ability to move about freely
immobility refers to
inability to move about freely
factors influencing mobility
immobility
bed rest
effects of muscular deconditioning
disuse atrophy
physiological
psychological
social
why bedrest?
- reduces oxygen needs
- decreases pain levels
- helps regaining of strength
- uninteruppted rest has psychological and emotional benefits
types of bed rest
bed rest
bed rest with bathroom privileges
immobility may be
- temporary, such as following surgery of total knee replacement
- permanent, such as parplegia
- sudden onset, such as fractured arm and leg following MV accident
- slow onset, such as mutliple sclerosis
pathological influences on mobility
- postural abnormalities
- muscle abnormalities
- damage to CNS
- musculoskeletal trauma
metabolic effects of MSS
endocrine
calcium absoprtion
GI function
respiratory effects of bed rest
atelectasis and hypostatic pneumonia
CV effects of bed rest
orthostatic hypotension
thrombus
MS changes due to bed rset
loss of endurance
loss of muscle mass
decreased stability and balance
muscle effects from bed rest
loss of muscle mass
muscle atrophy
skeletal effects of bed rest
impaired calcium absorption
joint abnormalities
