Module 8 Flashcards
what is the musculoskeletal system comprised of
bones, joints, skeletal muscles and supportive CT
what are supportive connective tissue
tendons, ligaments, and caritlage
connect muscles to bones
tendons
connect bones to eachother at the joint level
ligaments
cushioning tissue within a joint
cartilage
close to the center of the body
proximal
away from the center of the body
distal
moving the extremity laterally, away from midline
abduction
moving the extremity medially, toward the midline
adduction
rotating the extremity medially along its own axis
internal rotation
rotating the extremity laterally along its own axis
external rotation
moving the thumb outward to touch the little thumb
opposition
review of related history
past history, trauma, surgery on bone, skeletal deformities, chronic illness
current complaints
back, joint, muscular, skeletal complaints/pain, and injury
family history
Congenital abnormalities or genetic disorders, scoliosis, arthritis
personal and social history
employment, exercise, functional abilities, weight and height changes, tobacco and alcohol use, nutrition
sports injury risk factors
poor conditioning, not warming up, intensity of competition, collision, rapid growth, overuse
Main Risk Factors: Osteoarthritis
obesity, family history, lax ligaments with postural joint deformity, > 40 yrs old
additional risk factors for osteoarthritis
race, light frame, post menopause, constant dieting, scoliosis, metabolic disorders, some drugs, smoking and alcohol
equipment of musculoskeletal
Skin marking pencil, Goniometer, Measuring tape, Reflex hammer, Sphygmomanometer
what do you check during inspection
Alignment, Contour, Symmetry, Height/weight, Gross deformity, Posture, weight bearing tolerance, and gait
Affected foot/leg does not touch the floor
non weigh bearing
Touches floor, but no weight placed
touchdown weight bearing
30-50% of weight born
partial weight bearing
50% but < 100%
weight bearing as tolerated
what do you compare during inspection and palpation
contralateral sides
a discrepancy of what between the two contralateral parts is abnormal
> 3 cm
how do you inspect and palpate muscles
Contract muscle isometrically
Then relax muscle
Then contract again
Watch for any involuntary movements
without inducing movement
isometric muscle contraction
Flaccidity
Decreased muscle tone
hypotonicity
Increased muscle tone
Often noted with extreme flexion or extension
Spasticity
partial dislodgment of the bone from its place in the joint cavity
subluxation
dislodgment of one bone out of the joint cavity
dislocation
when do you stop ROM exercises
if person complains of pain
