Flashcards in Week 6 McKenzie Method Deck (5):
1

*Explain the underlying concept of lumbar flexion and its role in disc protrusions in the McKenzie school of thinking

- In a Flexed position the anterior part of adjacent vertebral bodies will approximate, thus narrowing the IVD anteriorly and causing the nucleus to move posteriorly and bulge in that direction

- In Extension the posterior part of adjacent vertebral bodies will approximate, thus narrowing the IVD posteriorly and causing the nucleus to move anteriorly

-This is demonstrated by intrathecal pressures =
Lying = 20%
Standing = 100%
Sitting flexed = 166%
Bending over = 220%
Standing up from chair = 220%
Lifting 20 Kg, neutral = 220%
Lifting 20 kg, flexed = 460%

*Provide possible explanations on how the McKenzie system may work

1. Improves the Lx lordosis
(Purepong et al., J Body Mov Ther, 2012)

2. Activate the TrA and MM ?
(Hosseinfar et al., J Phys Ther Sci, 2013)

3. Inducing an immune activation state and increased cytiokines
(Al-Obaidi, Mahmoud, Acta Med Acad. 2014)

4. Reduces fear and disability ?
(Al-Obaidi et al.,PM R. 2011)

*Define CENTRALISATION

= movement or position causing symptoms to move from a distal/lateral position to a more proximal location, closer to the midline of the lumbar spine

- holds strong prognostic value for Pts with LBP as the presence of centralisation has far better Tx outcomes than no change or peripheralisation.
