Flashcards in Stretching Deck (24):
1

What is functional ROM?

The ability of structures or segments of the body to move or be moved to allow the presence of ROM for functional activities

2

What is functional mobility?

The ability to of an individual to initiate, control or sustain active movements of the boy to perform simple to complex motor skills

3

What is Flexibility of Extensibility?

The ability to move a single joint or series of joints

4

What is hypomobility?

Decreased mobility or restricted motion caused by adaptive shortening of soft tissues

5

What is hypermobility?

Stretch of a joint or surrounding soft tissues well beyond the normal length of muscle and ROM

6

What is a contracture?

Adaptive shortening of the muscle-tendon unit and other soft tissues that cross or surround a joint that results in significant resistance to stretch, limits ROM, and may compromise functional abilities

7

6 Types of Contractures

Myostatic contracture

Arthrogenic and periarticular contractures

Adhesions/Scar tissue adhesions

Fibrotic contracture

Irreversible contracture

Pseudomyostatic contracture

8

What is the primary source of muscle’s resistance to elongation or stretch?

The connective tissue framework of muscle

9

What are the two sensory organs of muscle-tendon units?

Muscle spindle and Golgi Tendon Organ (GTO)

10

What is the muscle spindle?

The major sensory organ of muscle and is sensitive to quick and sustained stretch

11

What is the main function of muscle spindles?

To receive and convey information about changes in the length of a muscle and the velocity of the length changes

12

Muscle spindle fibers transmit info via what?

type Ia and type II afferent fibers

13

Two ways to stimulate the muscle spindle fibers

- Stretch
- Gamma efferent neural pathways

14

What is the GTO?

The Golgi tendon organ is a sensory organ located near the musculotendinous junctions of extrafusal muscle fibers.

15

What is the main function of the GTO?

Monitor tension in muscle from passive stretch or and active muscle contraction

It is a protective mechanism that inhibits tension

16

GTO fibers transmit info via what?

Type II B fibers

17

_________ stretch reflex occurs when a muscle is stretched quickly

Monosynaptic

18

Connective tissue is composed of what three types of fibers

1) Collagen fibers
2) Elastin fibers
3) Reticulin fibers

19

How are tendon collagen fibers arranged?

parallel and resist the greatest tensile forces

20

How are skin collagen fibers arranged?

random and weakest in resisting tension

21

6 Essential Elements of a Stretching Program

1) Alignment and stabilization
2) Intensity of stretch
3) Duration of stretch
4) Speed of stretch
5) Frequency of stretch
6) Mode of stretch

22

___ load and ___ intensity stretch usually results in optimal rates of improved ROM

Low
Low

23

How long should you hold a stretch?

At least 30 seconds

24

3 Types of PNF Stretching

- Contract-Relax
- Agonist Contraction
- Contract-Relax with Agonist Contraction
