1

Isometric contraction

Contraction of a muscle with no change in distance between origin and insertion

2

Concentric isotonic contraction

Contraction of a muscle with approximation of origin and insertion

3

What is muscle energy

The voluntary contraction of a patient muscle in a precisely controlled direction with varying levels of intensity against a distinctly executed counterforce

4

What is the active technique for MET

Patient contributes to the corrective force

5

What is the direct technique for MET

Positioned to the restrictive barrier

6

What is isometric contrction

Contraction of a muscle with no change in distance between the origin and insertion

7

What is concentric isotonic contraction

Contraction of a muscle with approximation of origin and insertion

8

What is eccentric isotonic contraction

Contraction of a muscle with separation of origin and insertion

9

What is isolytic contraction

Non-physiological

Attempted concentric contraction with an external force causing separation of origin and insertion

10

What is the most common form of MET

Post-isometric relaxation

11

What is post-isometric relaxation

Muscle contraction - increased tension in GTO - inhibition of muscle contraction

12

What are the indications for MET

Balance muscle tone

Strengthen reflexively weakened muscles

Improve symmetry of articular motion

Enhance circulation of body fluids

13

What are the four factors that can influence a wrong MET (patient)

1. Contact too hard
2. Contact in wrong direction
3. Sustain the contraction for too short a time
4. Do not relax appropriately following contraction

14

What factors influence an incorrect MET (operator)

Not controlling the joint position in relation to the barrier movement

Not providing the counterforce in the correct direction

Not giving accurate instructions

Moving to a new joint position too soon

15

What are some contraindications for MET

Local fracture
Local dislocation
Instability in CS
Low vitality
Can not follow commands
Neurological symptoms

16

What is the articulatory approach

Low velocity/high amplitude direct technique

Gentle and repetitive motions through the restrictive barrier to restore physiological motion

17

Is the patient relaxed or participating in ART

Relaxed

18

Isometric contraction simple understanding

Light to moderate contraction with an unyielding contraction

19

Isotonic contraction simple understanding

Hard to maximal contraction with a counterforce that permits controlled motion
