17
Q

four components of levers

A

a rigid bar/bone
an axis or fulcrum, point of rotation/joint
a resistance force
an effort force

18
Q

effort force and resistance are on either side of the axis

A

first class lever

19
Q

effort fore and resistance force are on the same side of the axis

resistance force lies between the effort force and the axis of rotation

A

second class lever

20
Q

effort force and resistance force are on the same side of axis

effort force lies between the resistance force and the axis

A

third class lever

21
Q

the moment of force and ability of a force to cause rotation of the leve

A

torque

22
Q

rotation of the lever depends on ____

A

magnitude of the force and distance from the axis

23
Q

how is torque calculated

A

lever arm x Fy
Fm x movement arm

24
Q

a movement’s magnitude depends on

A

force applied
force’s movement arm

25
Q

depicted as a vector with a line of application

A

force applied

26
Q

the perpendicular distance from the force’s line of application to the axis of rotation

A

force’s movement arm

27
Q

assessment of movement

A

strength
ROM

28
Q

how to palpation

A

feel bony landmarks and soft tissue around the joint

use pads of index and middle finger to palpate

avoid contact with fingernails

apply pressure gently but firm enough to feel underlying muscle, tendon, bones

29
Q

the amount of movement that is possible at a joint

A

ROM

30
Q

3 types of ROM

A

active, active assisted, passive

31
Q

a joint moved by a muscle/internal force

A

active ROM

32
Q

joint moved by patient internally with the assistance of therapist, equipment, or self externally

A

active assisted ROM

33
Q

a joint moved by an outside force such as therapist

A

passive ROM

34
Q

the normal resistance to further joint motion due to stretching of soft tissues, ligaments, and joint capsule

A

end-feel

35
Q

hard end-feel

A

bone to bone

36
Q

soft end-feel

A

muscle to muscle

37
Q

firm end-feel

A

ligaments to joint capsule

38
Q

occurs when ROM is increased or decreased or when ROM is normal but structures other than normal anatomy stop

inflammation, pain, fracture, etc.

A

abnormal end-feel

39
Q

MMT can measure

A

muscle strength and maximal muscle contractions

40
Q

break test steps

A

position the client, initially to move joint against gravity

stabilize proximal to muscle group being tested to eliminate extraneous movements

palpate prime movers

observe for possible substitutions and amount of range completed

hold end position and apply resistance

41
Q

where is MMT usually started on the scale

A

3: fair: part moves through complete ROM against gravity
