31
Q

Contraindications/Precautions To Stability Training

Red Flags

32
Q

Contraindications/Precautions To Stability Training

Yellow Flags

A

Hypermobility, Pregnancy, Joint Effusion, Inflammation, or Weak Connective Tissue

33
Q

How to determine clinical instability?

A

Assess Passive Subsystem
(Ligaments, Discs, Joint Capsule)
Assess Active Subsystem
(Specific Muscle Assessment)

34
Q

Exercises should be selected that allow the lowest load on the spine. Low shear or compressive forces. Focus initially on local muscles. Global muscle training once local muscles are working appropriately without excessive global activation.

A

Stabilization Exercises

35
Q

Facilitate accuracy of movement and motor control. Facilitate optimal efficient pain free functional movement. Initially focus on muscle coordination and endurance, not strength.

A

Goals of Stabilization Exercises

36
Q

Cervical spine has a large neutral zone. Due to lack of tension in capsular and ligamentous structures. Muscular system must be recruited to control motion with in the neutral zone.

A

Cervical Neutral Zone

37
Q

Deep (Local) Layer Segmental Stabilizers Flexors, Extensors
Middle and Superficial Layers

A

Active Subsystem

38
Q

Bowl model similar to hinge joint. The marble is the ROM of the joint. The sides of the bowl are the passive structures at end range. (End range will tear and hurt joint)

A

Bowl Model (Potential Energy and Stability)

39
Q

Damaged passive tissue or a muscle with inappropriate force can upset this system and cause instability.

A

Bowl Model(Potential Energy and Stability)

40
Q

The portion of intervertebral ROM where passive structures provide little resistance to movement.

A

Neutral Zone

41
Q

Near a joints’s neutral position. Joint capsule and ligaments are enough on slack to not affect motion.

A

Neutral Zone

42
Q

From either end of the neutral zone to the physiological end of ROM. The further one goes into the elastic zone the more the joint capsule and ligaments tighten and limit motion.

A

Elastic Zone

43
Q

ROM repeatedly getting to the end of the neutral zone can cause shear forces which can cause acute buckling or instability if forces are repeated over a prolonged period of time.

A

Elastic Zone

44
Q

If the passive joint structures lengthen, the size of the neutral zone will increase. A greater degree of ROM can then occur without tightening of articular structures. Muscles and motor control systems must then work overtime to maintain stabiltiy. Example: Bowl, Baseball Player (Flexible but not instability)

A

Hypermobility

45
Q

Joint structures contribute to ____ especially at and near end range.

A

Passive Stability

46
Q

Keep joints stable through muscle activation and by placing joints in positions where passive structures protect the joint.

A

Motor Control Systems

47
Q

Can lead to inappropriate muscle force, causing a gully and allowing the “ball to roll out” of the bowl. Joint can buckle or undergo shear translation.

A

Faulty Motor Control System

48
Q

Occurs when there are significant decreases in the ability of the stabilizing system to maintain the neutral zone. Often due to an increase in the size of the neutral zone.

A
