Leander Technique

A method of introducing a patient’s spine to continuous passive motion for a short period of time for the purpose of analyzing the degree of motion or

fixation of a spinal motion unit, augmenting the manual adjustment,

and then re-checking to ascertain the efficacy of the adjustment.

Spinal Motion Unit

Is made up of two adjacent vertebrae and their intervening soft tissues. Motion or fixation is described in terms relative

to the subjacent vertebra.

Distraction

• Distraction: The separation of joint surfaces through mechanical means, and is an articular phenomenon rather than simply a musculotendinous stretching, as in the case of traction.

Long Axis Distraction

• L.A.D. is the separation of vertebral joint surfaces in the Y plane of the three plane coordinate system. It is generally palpable as a separation of adjacent spinous processed during motorized flexion distraction.

Long Axis Fixation

• L.A.F. is the restriction of the normal separation of vertebral joint surfaces. It is represented by a lack of palpable separation of the spinous processes when the spine is under motorized flexion distraction.

Motion Assisted Palpation

• Palpation of vertebral long axis, rotation, and lateral flexion joint play, or the lack thereof, during motorized flexion distraction, and lumbar flexion and extension joint play during side posture lateral table flexion.

Motion Adjusting

• Motion adjusting is the manual correction of single or multiple joint fixation while the motion unit is placed in continuous passive flexion distraction on a motorized flexion distraction table.

Page 17: Flexion /Distraction AT5422 Introduction to Flexion / Distraction

F/D Benefits – 4 main benefits

• 1) Increase of the intervertebral disc height to remove annular distortion in the pain sensitive peripheral annular fibers.

• 2) Allow the nucleus pulposus to assume it’s central position within the annulus and relieve irritation of the pain sensitive fibers.

Page 18: Flexion /Distraction AT5422 Introduction to Flexion / Distraction

F/D Benefits – 4 main benefits

• 3) Restore vertebral joints to their physiological relationships of motion

• 4) Improve posture and motion while relieving pain and improving body function

Subluxation

A motion segment, in which alignment, movement integrity,

and/or physiological function are altered although contact between

joint surfaces remains intact.

Motion Assisted Palpation (MAP)

Motion assisted palpation is the analysis of spinal joint motion during motorized

continuous passive motion flexion distraction.

Page 27: Flexion /Distraction AT5422 Introduction to Flexion / Distraction

During motorized flexion/distraction, there should be a small yet palpable separation occurring between two adjacent vertebrae.

Long Axis Distraction (LAD)

Page 28: Flexion /Distraction AT5422 Introduction to Flexion / Distraction

Loss of the normal movement between spinous processes:

•Long Axis Fixation (LAF)

»Primary Fixation

Page 29: Flexion /Distraction AT5422 Introduction to Flexion / Distraction

Secondary Component

•When present will be at the same level as the primary fixation.

•Rotation

•Lateral wedging

•All of the above and more

Page 30: Flexion /Distraction AT5422 Introduction to Flexion / Distraction

Thoracic (Rotation)

•Head rotation to one side causes the spinous processes to rotate to the opposite side…approximately the level of L2.

Page 31: Flexion /Distraction AT5422 Introduction to Flexion / Distraction

Lateral flexion

Lack of movement of the spinous processes during lateral flexion indicates an

open wedging on the side of attempted lateral bending.

Page 32: Flexion /Distraction AT5422 Introduction to Flexion / Distraction

Lumbar (Lateral Flexion)

From C2 to T6, the spinous processes will tend to rotate away from the direction of lateral flexion (toward the convexity) From T6 on down, the spinous processes will tend to rotate towards the direction of lateral flexion (toward the concavity)

Page 33: Flexion /Distraction AT5422 Introduction to Flexion / Distraction

Malposition

Describes an abnormal position of an object.

Page 34: Flexion /Distraction AT5422 Introduction to Flexion / Distraction

Misalignment = Malposition

Malposition = Fixation

Fixation = next slide

Page 35: Flexion /Distraction AT5422 Introduction to Flexion / Distraction

Fixation

– Loss of normal motion of the joint.

The fixation can be found anywhere within the normal physiological range of

the joint when the examiner motion palpates the segment.

Page 36: Flexion /Distraction AT5422 Introduction to Flexion / Distraction

Causes of a Fixation

•Trauma

•Toxins

•Thoughts

•Postural Defects

•Disuse

•Congenital abnormalities

Page 37: Flexion /Distraction AT5422 Introduction to Flexion / Distraction

S/S of Fixation

•Pain

•Spasm

•Edema

•Loss of tone and strength

•Impaired circulation

•Formation of trigger points

•Hypo/Hypermobility

Page 38: Flexion /Distraction AT5422 Introduction to Flexion / Distraction

Fixation is where the vertebral body is stuck.

Restriction

is where the vertebral body cannot go.
