McKenzie Approach Flashcards
The McKenzie method is AKA
Mechanical diagnosis and Therapy
McKenzie definition
Philosophy of active pt involvement and education
Approach to examination, intervention, and prevention
Used throughout the world for back, neck, and extremities
Peripheralization
pain moves laterally away from the center of the spine and/or down the extremity
Centralization
symptoms move proximally up the extremity and toward the center of the spine
Even if the pain becomes more intense, it is centralizing
Centralization phenomenon
Radiating symptoms originating from the spine move proximally toward the midline of the spine as the result of repeated motion or adoption of certain positions
Centralization phenomenon - Movements that promote centralization can be used to
abolish radiating symptoms
Localized central pain adjacent to the spine may increase
Biomechanics of IVD - 1st stage of protrusion
displacement sufficient only to cause distortion of nociceptors in annulus and or PLL
Biomechanics of IVD - greater pressure on nerve root =
more distal sx are felt
Biomechanics of IVD - with annular wall still compentent (first two stages) what can happen
posterolateral protrusions may be reversible using sagittal extension forces
Contraindications
Fractures (suspected or diagnosed) Metastases Cauda equina Osteoporosis Progressive neurological disease Inflammatory joint disease (RA, AS, Reiter's syndrome)
McKenzie classification - mechanical diagnosis includes
Postural syndrome
Dysfunction syndrome
Derangement syndrome
Postural syndrome
Intermittent pain only with STATIC prolonged loading of NORMAL tissues
Mechanical deformation of peri-articular soft tissue as a result of postural stress
Postural syndrome - what changes pain
Pain is decreased with moving out of aggravating posture and repeated movement
Intervention for postural syndrome is
Postural education/ergonomics
Dysfunction syndrome
Adaptive shortening of mechanically deformed tissues
Dysfunction syndrome - cause
Past trauma, pain, poor posture, degeneration can be cause
Fibrous repair of above leading to abnormal tissue with restricted and painful end range
Dysfunction syndrome - description of s/s
Intermittent pain
Articular dysfunction with pain at limited end range
Pain as tissue is stressed through posture or activity
End range pain stops on cessation of loading
The pain does not peripheralize or worsen with repeated movement
Dysfunction syndrome - intervention
Treat with the movement that produces the pain!!!
Goal is to stretch the tightened muscles and connective tissue
Derangement syndrome
MOST COMMON
Disc mechanics
Certain loading pattern - peripheralization of s/s, opposite loading pattern centralizes the s/s
Derangement syndrome - repeated movement in the direction that increase accumulation of nuclear material results in
Progressively increasing derangement/peripheralization of pain
Derangement syndrome - loading strategies ex for lumbar - if inc pain with sitting (flex)
Dec pain with walking (ext)
Derangement syndrome - loading strategy ex for cervical - if inc peripheralization with protrusion
centralization with repeated retrusion
Derangement syndrome intervention
Treat with movement that relieves pain to decrease mechanical deformation of the derangement
