Force Flashcards
where should the axis/fulcrum of goniometer be placed?
axis of the joint
where should the moveable arm of the goniometer be placed?
parallel to the longitudinal axis the MOVING bone/part
where should the stationary arm of the goniometer be placed?
parallel to longitudinal axis the PROXIMAL part
what is the difference in measuring for initial assessment and interim assessment?
initial: both sides measured
interim: involved side only
what are the mathematics of force?
force = mass x acceleration
what are the characteristics of force?
magnitude
line of application
point of application
are muscles internal or external force?
internal
what prevents movement?
friction
what are consequences of forces on the body?
joint compression (standing) joint distraction pressure on body tissue
what is newtons 1st law?
“law of inertia”
object at rest will remain at rest unless acted on
object in motion continues in motion with same speed + direction unless acted on
what is newtons 2nd law?
“law of acceleration”
acceleration is produced when force acts on a mass
greater the mass greater the amount of force needed
what is newtons 3rd law?
“law of reciprocal actions”
for every action there is an equal opposite reaction
what can analysis provide?
weak + strong points in joint positions
ID important part of skill in terms of movement
ID parts of skill or movement that might cause injury
what is important when giving MMT?
care in handling injured part
positioning to avoid pain, discomfort
gentleness to test weak muscles
ability to apply pressure to facilitate pts optimal response
what to avoid when giving MMT?
not paying attention to details that could affect accuracy
failure to take into account all factors
documenting inaccurate results
