Chapter 47 mobility and immobility Flashcards
Visible aspect and contributes to self-worth and well-being
Movement
Used to show self-defense, perform activities of daily living (ADLs) and recreational activities
Mobility
Coordinated efforts of the musculoskeletal and nervous system
Body mechanics
Reduces strain, maintains muscle tone, comfort, conserves energy
Body alignment
Required to maintain a static position
Balance
Force that occurs in a direction to oppose movement
Friction
Contribute to height
Long bones
Occur in clusters (carpal bones in the foot)
Short bones
Provide structural contour (skull)
Flat bones
Make up the vertebral column and some bones of the skull
Irregular bones
Caused by weakened bone tissue
Pathological fractures
Bones jointed by bones with no movement
Synostosis joint
Unites bony components
Cartilaginous joint
joint in which a ligament unites two bony surfaces (paired bones of the lower leg)
Fibrous joint
Ball and Socket Joint (hip)
Synovial joint
Fibrous tissue that connect ones an cartilages
Ligaments
Connect muscle to bone
Tendons
Nonvascular, supporting tissue (joints and thorax)
Cartilage
Increased muscle contraction causes muscle shortening resulting in movement
concentric tension
Helps control the speed and direction of movement
Eccentric tension
Active movement between concentric and eccentric muscle actions
Isotonic contraction
Causes an increase in muscle tension or muscle work but no shortening or active movement
Isometric contraction
Inducing or compelling force
Leverage
Position of the body in relation to the surrounding space
Posture
Normal state of balanced muscle tension
Muscle tone
Inclining of head to affected side, in which sternocleidomastoid muscle is contracted
Torticollis
Exaggeration of anterior convex curve of lumbar spine
Lordosis
Increased convexity in curvature of thoracic spine
Kyphosis
Lateral S- or C-shaped spinal column with vertebral rotation, unequal heights of hips and shoulders
scoliosis
Hip instability with limited abduction of hips and, occasionally, adduction contractures (head of femur does not articulate with acetabulum because of abnormal shallowness of acetabulum)
Congential hip dysplasia
Legs curved inward so that knees come together as person walks
knock-knee
One or both legs bent outward at knee, which is normal until 2 to 3 years of age
Bowlegs
95%: medial deviation and plantar flexion of foot (equinovarus) 5%: lateral deviation and dorsiflexion (calcaneovalgus)
Clubfoot
Inability to dorsiflex and invert foot because of peroneal nerve damage
Footdrop
Internal rotation of forefoot or entire foot; common in infants
Pigeon Toes
Damage to component of the central nervous system that regulates voluntary movement results in
impaired body alignment, balance, and mobility
Direct trauma to the musculoskeletal system results in
bruises, contusions, sprains, and fractures
inability to move freely
Immobility
Identify the objectives of bed rest.
a. Reducing physical activity and the oxygen needs of the body
b. Reducing pain, including postoperative pain or after acute injury, to the lower back
c. Allowing ill or debilitated clients to rest
d. Allowing exhausted clients the opportunity for uninterrupted rest
Identify the complications of immobility in relation to the metabolic functioning of the body
decreases the metabolic rate; alters the metabolism of CHO, fats, and proteins; causes fluid and electrolyte and calcium imbalances; and causes GI disturbances
collapse of alveoli
Atelectasis
inflammation of the lung from stasis or pooling of secretions
Hydrostatic pneumonia
