Q

When should you introduce CKCEs and OKCEs in a proprioceptive retraining program?

A

Initially CKCEs should be performed within the pain-free ROM and positions. Then, OKCEs, such as plyometrics, may be built upon the base of the closed-chain stabilization to allow normal control of joint mobility.

36
Q

What does the neutral zone refer to?

A

A region of laxity around the neutral resting position of a joint in which minimal loading is occurring in the passive structures, and the contribution of the active system is most critical

37
Q

What are the 2 primary dynamic bases or core structures in which peripheral stabilizers relay on the stabilization of?

A

the pelvis and the scapula

38
Q

What does the pelvis act as a base for?

A

the whole body, especially for the spine and the lower limbs

39
Q

What do the scapulae act as a base for?

A

for their respective upper limb

40
Q

During peripheral joint movement, which muscles contract first?

A

The peripheral stabilizer contracts first to stabilize the core structure from which the mobilizers work, followed by mobilizer contraction resulting in a controlled movement pattern

41
Q

What happens if there is injury to the stabilizer muscles?

A

An abnormal stabilizer recruitment pattern can develop, resulting in a dominance of the mobilizer muscles and eventual weakening of the local stabilizers

42
Q

In order for stabilization training to be effective, what must the clinician ensure?

A

that a stable base is present from which the mobilizers can act

43
Q

Once stabilizer muscles are functioning, what is the sequence of stabilization retraining?

A

isometric to concentric, to eccentric, and ecocentric contractions, and finally to functional movement

44
Q

When does an ecocentric contraction occur?

A

When a 2 joint muscle shortens at one end, while lengthening at the other end

The hamstring when moving from standing to sitting for example

45
Q

What are the 6 natural stabilization methods the body has?

A
  • Muscle contraction
  • Muscle spasm
  • Osteophyte formation
  • Scar tissue formation

47
Q

When does stage one of stabilization retraining occur?

A

in the acute phase of healing

48
Q

Describe step one of stage one of stabilization retraining

The focus is to decrease pain through muscle relaxation techniques, patient education on joint resting positions and proper body mechanics, the use of electro physical agents, working in the pain-free range, and the use of medication

49
Q

Describe step two of stage one of stabilization retraining

A

Freedom of movement and proper arthrokinematic movement of the joint movement of the joint is allowed through joint mobilization, prolonged passive stretch, muscle energy techniques (METSs), and neurodynamic techniques depending on the tissue causing the restriction

A

Initial emphasis is directed toward strengthening any weak stabilizer muscles to ensure that the individual muscles will contract when and how they should, starting with isometric contractions of these muscles

52
Q

Describe step two of stage two of stabilization retraining

A

The goal is the ensure proper muscle recruitment and reeducation so that the muscles contract in the correct order – stabilizers first, then mobilizers

53
Q

Describe step three of stage two of stabilization retraining

A

The goal is to ensure muscle balance between groups to ensure that the various force couples work correctly and function to enable control and eliminate incoordination
