Exam 2: ROM Flexibility & PNF Strengthening Flashcards
(23 cards)
1
Q
Muscle spindles
A
- sensitive to stretch & velocity in muscle length –> contraction (excitatory)
- Made of intrafusal fibers: nuclear bag (more sensitive) & nuclear chain sensitive to stretch
2
Q
Golgi Tendon Organ (GTO)
A
sensitive to muscle contraction –> autogenic inhibition of muscle (inhibiory)
3
Q
Flexibility
A
- mobility of muscle & length to which they can extend
- interchangeable w/ ROM
4
Q
ROM
A
- amount of movement possible @ a joint
- interchangeable w/ flexibility
5
Q
Balance
A
ability to maintain center of gravity over base of support
6
Q
Coordination
A
complete complex movement
7
Q
Agility
A
directional control of body/parts
8
Q
Hold-relax
A
- Purpose: stretching for muscle tightness
- Technique: isometric contraction of antagonist; contraction of agonist w/ stretch of antagonist
9
Q
Contract-relax
A
- Purpose: stretching for muscle tightness
- Technique: isotonic contraction of antagonist; passive stretch of antagonist
10
Q
Autogenic inhibition
A
- muscle stretch causes both muscle spindles & GTO signals
- stretch held for 6+ seconds causes inhibitory signals to override excitatory signals –> muscles relaxes
11
Q
Reciprocal inhibition
A
contraction of agonist –> relaxation of antagonist allowing it to stretch
12
Q
Rhythmic stabilization
A
- Purpose: increase holding strength
- Technique: isometric contraction of agonist & antagonist
13
Q
Repeated contractions
A
- Purpose: weakness @ specific point; strength through a range
- Technique: repeated isotonic contraction; concentric & eccentric
14
Q
Slow reversal
A
- Purpose: normal reciprocal timing
- Technique: isotonic contraction of antagonist followed by isotonic contraction of agonist
15
Q
Slow reversal hold
A
- Purpose: strength @ specific points in ROM
- Technique: isotonic contraction of agonist & antagonist w/ isometric contraction @ end point of pattern
