Questions 2 Flashcards
How is passive insufficiency different from joint ROM?
Passive insufficiency has to do with muscle length whereas joint ROM has to do with joint structures (ligaments, articular cartilage, joint shape).
If a muscle that crosses 2 or more joints cannot passively elongate enough to all full simultaneous motion in all joints that if crosses, that is called?
Passive insufficiency
Horizontal plane is?
vertical axis
Sagittal plane is?
Medial-lateral axis
Frontal plane is?
Anterior-posterior axis
What does a minus sign before the first number mean when recording ROM measurements?
The client cannot get to anatomic position (fully extend or abduct)
What is the sum of flexion active range of motion at the metacarophalangeal, proximal interphalangeal and distal interphalangeal joints, minus any active extension lack (short of zero) at these three joints?
Total active motion
The finger metacarpophalangeal joint is measured in one movement, from hyper-extension to flexion. According to recording ROM, index finger metacarpophalangeal AROM of +25/25 indicates what?
Hyperextension and lack of full flexion
A plane joint is an example of?
diathrosis
What are mandatory characteristics of a synovial joint?
- Sensory nerves in joint capsule
- Joint cavity filled with synovial fluid
- Blood vessels in the joint capsule
- Capsular ligaments
- Articular cartilage covering the ends of the bones
You ask a client who is seated in front of you with their arm at their side to flex their elbow against gravity. Form a fully extended position, they can only flex it 30 degrees or so. You know that the patient has full PROM at that elbow. In order to determine their muscle strength grade, your next step would be to?
Put the patients arm in a gravity-minimized position and ask them to flex their elbow in that position.
T/F - Manual muscle testing has poor validity but good inter-rater reliability?
False
Which of the following joints typically has 1 degree of freedom?
Pivot joint
You ask your patient to extend their wrist, and they demonstrate full AROM against gravity; furthermore, they are able to take slight resistance before “breaking”. What is the muscle grade?
3+/5
A firm end feel indicates what?
Connective tissue around the joint tightening
- Heteropic ossification
- Unhealed fracture in a bone adjacent to the joint
Are examples of?
Contraindications to measuring ROM
According to the biomechanical frame of reference. What is the first deficit that is addressed?
Structural stability
The interphalangeal joints of the fingers are?
hinge joint
T/F - A hard end feel is always pathologic?
False
Which of the following is not a precaution for manual muscle testing?
Osteoporosis
You ask your patient who is seated in front of you to flex their shoulder. They are able to complete this motion through a full ROM, but cannot take any additional resistance. Their muscle grade is?
3/5
