MET

Question 1

MET background

Answer 1

Mobilization technique that uses muscular facilitation and inhibition
Involves submaximal contraction

Question 2

Fryette’s Laws of Biomechanics - First

Answer 2

In the neutral lumbar spine, LF and Rot occur in opposite directions

Question 3

Fryette’s Laws of Biomechanics - Second

Answer 3

In the lumbar spine that is hyperextended or hyperflexed, LF and Rot occur in the same direction

Question 4

Fryette’s Laws of Biomechanics - Third

Answer 4

Motion introduced in one plane reduces motion available in other planes

Question 5

Type 1

Answer 5

Neutral mechanics

LF and Rot occur in opposite directions - Group (3 or more in neutral)

Question 6

Type II

Answer 6

Non-neutral mechanics

LF and Rot occur in the same direction - single segment

Question 7

Group Dysfunction (type 1)

Answer 7

Group of 3 or more segments
Minimal flex or ext component of restriction (neutral)
Restriction of the group into SB one direction and Rot opposite direction
Compensatory scoliotic mechanisms
Found above or below a single vertebral motion dysfunction

Question 8

Single Segment Dysfunction (type II)

Answer 8

Single vertebral motion unit involved
Includes flexion or extension restriction
Motion restriction SB and Rot to same side

Question 9

Normal Vertebral Motion
Flexion
Extension
Lateral Flexion
Direction of Motion Named

Answer 9

Flexion = facets open
Extension = facets close
Lateral Flexion = Ipsilateral facet closes, contralateral facet opens
Direction of motion named = ant/sup vertebrae (segment above)

Question 10

With left rotation, which transverse process is more prominent

Answer 10

Left

Question 11

Positional Dx = NSR(L)
Motion available
Motion restriction

Answer 11

Available - Flex, Ext, Side bend right, Rotate left

Restriction - Side bend left, Rotate right

Question 12

Positional Dx = ERS(L)
Available
Restriction

Answer 12

Available - Ext, Rotation L, Side bend L

Restriction - Flex, Rotation R, Side bend R

Question 13

Position Dx = FRS(R)
Available
Restriction

Answer 13

Available - Flex, Rotation R, Side Bend R

Restriction - Ext, Rotation L, Side Bend L

Question 14

Diagnosis - ERS
Facet
Extension
Flexion
Restriction

Answer 14

Extended, Rotated, Side Bent
Ipsilateral Facet is not opening
Upon extension = TPs become more symm
Upon flexion = Ipsilateral TP more prominent
Restricted = Flex, opp rot, opp side bend

Question 15

Diagnosis - FRS
Facet
Extension
Flexion
Restriction

Answer 15

Flexed, Rotated, Side bent
Open facet is not closing 
Upone ext, TP is more prominent 
Upon flex, TPs become more symmetrical 
Restricted = Ext, opp rot, opp side bend

Question 16

Ex = ERS (R)
Facet?
Flexion
Extension
Restriction
Dx

Answer 16

Facet = R facet does not open
Flex = R TP is prom
Ext = TPs more equal
Restriction = Flex, L SB, L Rot
Dx = ERS (R)

Question 17

Ex = FRS (R)
Facet?
Flex
Ext
Restriction
Dx

Answer 17

Left facet will not close
Flex = TPs more equal
Ext = R TP more prom
Restriction = ext, Rot L, SB L
Dx = FRS (R)

Question 18

MET Indications

Answer 18

Abnormal neuromuscular relationships
To lengthen restricted or hypotonic muscles
To improve local circulation
To mobilize restricted joints

Question 19

MET Contraindications

Answer 19

Fracture
Severe Sprain
Severe Strain
Patients who cannot follow directions

Question 20

Common Errors

Answer 20

Inaccurate Dx
Inaccurate localization of corrective forces
Incorrect force, direction, or duration of contraction
Inappropriate relaxation following contraction
