1
Q

Flexibility

A

normal extensibility of all soft tissue that allows a joint to move through its full ROM

2
Q

Extensibility

A

capability to be elongated or stretched

3
Q

Dynamic ROM

A

optimal control of movement through joint’s full ROM; combination of flexibility & nervous system’s ability to control ROM efficiently

4
Q

Neuromuscular efficiency

A

ability of nervous system to recruit muscles to work correctly in all 4 ways, and to produce/reduce/dynamically stability force in all 3 planes

5
Q

Postural distortion pattern

A

predictable patterns of muscle imbalances

6
Q

Relative flexibility

A

body’s tendency to seek path of least resistance

7
Q

Muscle imbalance

A

alteration in length of muscles surrounding joints

8
Q

Reciprocal inhibition

A

simultaneous contraction of one muscle and relaxation of its antagonist, allowing movement; agonist gets signal to contract at the same time the antagonist gets the signal to relax

9
Q

Altered reciprocal inhibition

A

caused by tight agonist decreasing neural drive to its antagonist

10
Q

Arthrokinetic dysfunction

A

biomechanical and neuromuscular dysfunction leading to altered joint motion

11
Q

Autogenic inhibition

A

when neural impulses that sense tension are greater than impulses that cause muscles to contract, providing inhibitory effect to muscle spindles; the reason stretching creates changes in extensibility

12
Q

Pattern overload

A

consistantly repeating the same pattern of motion

13
Q

Davis’s law

A

states that soft tissue models along lines of stress

14
Q

Cumulative injury cycle

A

injury causes trauma, body responds with inflammation and spasm (overactivity), this forms knots, which alters neuromuscular control, and leads to muscle imbalances, which are prone to injury; risk compounds with each cycle

15
Q

Corrective flexibility

A

SMR and static stretching; to increase ROM and improve muscle imbalances and altered joint motion

16
Q

Active flexibility

A

SMR and active-isolated stretching; to improve soft tissue extensibility and neuromuscular efficiency

17
Q

Active-isolated stretching

A

agonists and synergists move limb through full ROM while stretching antagonists, creating reciprocal inhibition of muscle being stretched; 2 sets of 5-10 reps for 1-2 seconds

18
Q

Functional flexibility

A

SMR and dynamic stretching, using multi-planar movement and full ROM; requires movement without compensations

19
Q

SMR

A

corrects muscle imbalances, reduces trigger points, inhibits overactive muscles; find tender spot, and hold for 30 seconds

20
Q

Static stretching

A

corrects muscle imbalances and lengthens overactive muscles; stimulates GTOs and inhibits muscle spindles; hold for 30 seconds

21
Q

Active stretching

A

increases extensibility of soft tissues

22
Q

Dynamic stretching

A

active extension of muscle, using force production and momentum, to move joint through full ROM; increases extensibility with optimal neuromuscular control; uses reciprocal inhibition; do 1-2 sets of 10-15 reps of 3-10 exercises
