Q

Types of abnormal end feels

A

Boggy end feel
Muscle spasm
Empty end feel
Springy block

17
Q

Soft tissue edema present. Wet sponge feel

A

Boggy end feel

18
Q

Protective reaction to injury

A

Muscle spasm

19
Q

So much pain is present, clinician can’t get to end of ROM

A

Empty end feel

20
Q

Rebound movement at end of ROM. Internal damage to joint

A

Springy block

21
Q

The manner in which adjoining joint surface move on each other during osteokinematic joint movement

A

Arthrokinematic Motion

22
Q

Small arthrokinematic motions that accompany active osteokinematic motions. Do not happen independent of osteokinematic motion. Not under voluntary control

A

Component movements

23
Q

Arthrokinematic motion that happens between joint surfaces when an external force creates passive motion at a joint. Ex.) roll, glide, spin

A

Joint play

24
Q

Technique that applies external force to generate a passive oscillatory motion or sustained stretch between joint surfaces. CAN BE USED TO RESTORE ROM OR DECREASED PAIN. Manipulation

A

Joint mobilization

25
Cause joint distraction. Joint surfaces pull away from each other Ex.) carrying a heavy suitcase will cause distraction
Traction forces
26
Cause joint approximation. Joint surfaces are pushed together Ex.) doing a push up will cause approximation in the UEs
Compression forces
27
Cause a gliding motion. Joint surfaces move parallel to each other. Assist in restoring joint mobility
Shearing forces
28
Other than vertical force is applied and results in compresssion on the concave side and distraction on convex side
Bending
29
One force turning one end around longitudinal axis and another force is fixed or turning opposite direction
Rotary
30
Type of motion occurring at a joint depends on the shape of the joint surfaces. Most joints have one convex and one concave
Joint surface shape
31
two bones forming a convex-concave relationship. Most synovial joints. One home end typically larger than the other
Ovoid joint
32
Each joint surface is convex one direction and concave the other. Carpometacarpal (CMC joint of thumb)
Sellar/saddle shaped joint
33
Three potential motions at the joint surface
Roll Spin Glide
34
Rolling of one joint surface on another. New points on each surface come into contact through the motion
Roll
35
Linear movement of a joint surface parallel to the plane of the adjoining joint. One point contacts new points as it moves
Glide(slide)
36
Rotation of the moveable joint surface on the fixed adjacent surface
Spin
