History

• Elements of MET have been described and
  documented for many years (under different names
  and with different descriptive terminology)
• Fred Mitchell, Sr., D.O., F.A.A.O. is generally
  given credit for developing the MET system into
  its modern day form

3
General MET Principles

• The practitioner places the patient/clients
  somatic dysfunction(s) to a restrictive barrier.
• The patient/client is instructed to generate a
  specific force/muscle contraction.
• The practitioner provides isometric resistance to
  the patient/clients effort.
• The patient/client is instructed to stop their
  effort.
• The practitioner then repositions the
  patient/client through their previous barrier to
  a new barrier.
• The process is repeated until the desired effect
  is obtained.

4
General MET Types

• Post-isometric relaxation
• Also isotonic isolytic versions
• Reciprocal inhibition
• Joint mobilization
• Respiratory assistance
• Oculocephalogyric reflex (cervical)

5
Barrier Review

• Bind going into the restrictive barrier
  (direct)
• Ease going away from the restrictive barrier
  (indirect)

6
Reflex Review

• POST-ISOMETRIC RELAXATION
• Golgi Tendon Organ
• Located Within the Muscle Tendon (Extrafusal)
• Sensory Innervation Only
• Tension its Rate of Change
• Dynamic Response
• Static Response
• Involuntary Muscular Relaxation

7
Reflex Review

• RECIPROCAL INHIBITION

8
MET Indications

• Whenever somatic dysfunction is present and/or
  whenever there is a need to
• Normalize abnormal neuromuscular relationships
• Improve local circulation and respiratory
  function
• Lengthen and/or normalize restricted/hypertonic
  muscles and fascia
• Mobilize restricted joint(s)

9
MET Contraindications

• Fracture
• Severe Sprain (Ligament injury)
• Severe Strain (Myofascial injury)
• Uncooperative, unresponsive, or those that can
  not or will not follow directions

10
Common Errors

• Inaccurate diagnosis
• Inaccurate localization of corrective forces
• Incorrect force, direction, or duration of
  patient/clients efforts
