Barrier of Motion

Question 1

Tissue Texture Changes ( Acute)

Answer 1

Skin- warm, moist, erythematous

Soft tissues- boggy edema, acute congestion, fluids from vascular leakage

Muscles-increased tone, spasm ropiness

Mobility- ROM may be normal, but sluggish

Question 2

Tissue Texture Changes ( Chronic)

Answer 2

Skin- cool, pale

Soft tissues- doughy, stringy, fibrotic, thickened, contracted

Muscles-decreased tone, flaccid, mushy, or fibrotic

Mobility-ROM decreased, but quality is normal

Question 3

Anatomic Barrier

Answer 3

The final limit to motion in articulation beyond which tissue damage occurs

Question 4

Physiologic Barrier

Answer 4

The soft tissue tension that limits the voluntary motion of an articulation (active motion)

The barrier is maintained by:
Golgi Receptors
Muscle Spindles
Pacinian Receptors

Question 5

Elastic Barrier

Answer 5

The range between the physiologic and anatomic barriers in which passive stretching occurs before tissue disruption

Question 6

Restrictive Barrier

Answer 6

A functional limit that decreases the physiologic range.

Potentially reversible with appropriate treatment (OMM)

Question 7

Techniques for Muscular hypertonicity

Answer 7

Myofascial release, Muscle energy, soft tissue technique

Question 8

Techniques for Articular restriction

Answer 8

HVLA, articular technique

Question 9

Techniques for Restrictive Barriers

Answer 9

Pain – counterstrain, soft tissue, indirect technique

Edema – muscle energy, myofascial release,or lymphatic techniques

Muscle spasm – muscle energy or counterstrain

Fascial – myofascial release (direct or indirect)

Joint Surface – High Velocity / Low Amplitude (HVLA)

Question 10

Pathologic Barrier

Answer 10

Decreased motion resulting from a pathologic alteration of tissue

Question 11

Why know the barrier?

Answer 11

Normal ROM – no treatment needed

Abnormal ROM –( Normal ranges must be known)

Restrictive – identify the cause and choose treatment

Pathologic – OMM NOT appropriate
