Biomechanics: Osteopathic Style Flashcards
Who determined the position of the center of gravity?
B. Galileo
C. Giovanni alfonso borelli
E. Leonardo da Vinci
C
Which of the following applies stress to the joint during movement? A. anatomical joint lever B. cumulative load C. joint reaction force D. tissue deformation
C
Amount of force necessary to bend an object is known as? A. elasticity B. Shearing C. Stiffness D. Stress E. Tension
A
stress= hard structure; strain= soft structures (muscles)
Deformation can result in loss of: A. ROM B. relaxation C. resiliency D. viscosity
C
Which of the following is important in maintaining a full range of motion? A. bending B. Friction C. Partial contraction D. relaxation E. torsion
D and kinda A
A slow stretch resulting in more complete expression of fluid from within the matrix is known as: A. creep B. force C. friction D. strain E. strain
A
Synovial joints have movement in which planes?
All three
3 primary joint types?
fibrous, cartilaginous, synovial
Direction of movement of body is largely defined by?
structure of joints between them
Biomaterials are classified into what 2 groups?
Hard (bone)
Soft (skin, tendon, muscle, cartilage)
Hard tissue undergoes what kind of change?
deformation
compensatory change can lead to?
functional correction; adaption can result in unintentional alteration of structural function
Repetitive stress can cause alteration to structure in form of:
failure, deformation, and adaptation
Failure of tissue results in
altered mechanical relationship between unaffected structures
“guarding”
by structures protecting joint can create as much problems as original insult
main aspects of contact mechanics are related to what 3 things?
friction, wear, lubrication
In living tissue the ability to repair can result in an adaption leading to increased mass of the tissue:
callus, stress fracture
repeated stress can result in:
fatigue
Biotribology
study of biological systems, human joints
skeletal muscle adaptation
remodels according to the stresses placed upon it
hypertrophy with physical training results from
increased cross section of fibers
Atrophy results from disuse or functional alteration
of nerve stimulation
3 subsegmented “units”
core, shoulder girdle, pelvic girdle
15yo male headaches, nasal congestion. Diagnosed with sinusitis. Structural exam shows deviated septum; positive Chapman pts: sub occipital area and inferior to clavicle, over the first rib
fix deviated septum
67yo female exacerbated COPD; increased AP chest with diameter, increased thoracic kyphosis with flattening of the thoracolumbar junction, compensatory lordosis of the cervical spine and tenderness C4-7, bilateral elevated first rib, poor chest will excursion, poor chest wall compliance, paraspinal TART changes, T2-7
??
42yo obese, RUQ pain, jaundice. She is diagnosed with cholecystitis and choledocholithiasis. Exam: increased lordosis compensatory changes in lower thoracic spine, increased upper thoracic kyphosis with accentuated cervical lordosis, tart changes at T7-9 on the right, tenderness to palpation over medial 7th intercostal space
tart change T7-9 (chapman reflex point)
gallbladder fixed
can do OMT to temp. relieve pain
78yo male presents w/L knee pain. Osteoarthritis.
??
24yo plays pro-soccer works on loading dock in off season. Pain between 2-6/10, constant, radiates into groin notices worse when extends leg?
E. None of the above
24 yo, soccer player, intervention?
A. OMT and B. PT
