MULLIGAN’SMobilisation with

Movement:

Mobilisation With Movement =

sustained force (accessory glide)while a previously painful

(problematic) movement is performed

or ?


discern and measure problem movement

apply glide &repeat problem movement

repeat iteration (max 4 times) &observe outcome

or ?


only used in treatment plan if thepreviously painful (problematic)movement is much/substantially

improved

Biomechanical

Boney luxations

Reversing luxations

• Straighten spine (Pare 1958)

• Unlocking locked joint(Twomey 1992)

• Shift an IVD fragment (Cyriax1975)

• Reduce annular distortion(Farfan 1973)

• Stretching, tearing or rupturingadhesions that limit joint ornerve range (Zusman 1986,Chrisman et al 1964)

• Remove blockage orinterference of blood flow (Still1899), nerve compression(Palmer 1910), sympatheticchain (Kunert 1965), andcerebrospinal fluid circulation(DeJanette 1967)

Biomechanical

Neurophysiological

Paradigms in practice/research

• Correct abnormalsomatovisceral reflexes andvisceral organ dysfunction(Dhami & DeBoer 1992)

• Stretch contracted muscles,causing relaxation (Perl 1975)

• Remove ‘irrtable’ spinal lesions(Korr 1976)

• Intense reflex effects (mainlymusculature, Lewit 1985)

• Modulate peripheralnociceptors (Zusman 1987)

• Inhibition of reflex musclecontraction (Zusman 1987)

• Activates gating mechanism,neurotransmitters, opioidepeptides (Dhami and DeBoer1992)

MWM produces an initial hypoalgesia

Treatment effect > placebo/control procedures

Initial hypoalgesia = non-opioid mechanisms

Are these findings an expression ofthe ‘restoration of joint memory’

explanation provided by Mulligan?

23 subjects with LE and reduced shoulder externalrotation pre-intervention.

MWM for LE reversed the deficit in shoulderrotation.

Interpreted as MWM induced changes in shouldermuscle tone

implying neurophysiological effect

Chronic pain =conditioned (learned) phenomenon (Zusman 2004)

MWM = a re-conditioning of a pain-movement association -

[possibly through non-associative learning theory mechanism (Zusman 2004))]

Repetition seems to be critical in successful treatment!
