1How can context and environment affect movement?
Wind, friction, cold, heat
2Why is a static analysis of the body important for OT evaluation and treatment?
Posture, joint stability, symmetry, muscle imbalances
3Clinical examples:
Compression:
Tension:
Shear:
Compression: weightbearing
Tension: joint distraction
Shear: anterior/posterior joint mobilization on the shoulder; sliding someone out of bed rather than lifting and pulling
4What are examples of levers used in your daily routine?
Wheelbarrow, wrench, tweezers, nail clippers, all your joints
5Why are levers in the body important for function?
Improved mechanical advantage
6what force is applied during distraction of the shoulder
tension
7what force is applied with approximation of the shoulder
compression
8what force is applied with anterior posterior glide of the shoulder
shear
9Lift a water bottle directly out to side and hold it there for 3 seconds, then slowly lower it back to your side. Focusing on the deltoid muscle only:
isometric?
concentric?
eccentric?
isometric: holding it for 3 seconds
concentric: lifting the water bottle
eccentric: lowering the water bottle
10Simulate bringing food to your mouth. Which muscle(s) would be the agonist vs. the antagonist in this activity when focusing on the elbow?
agonist?
antagonist?
agonist: bicep and elbow flexors
antagonist: tricep
11why are there variations in sizes of goniometers
various joint sizes
12Which goniometer would be appropriate
shoulder:
