Study Notes
Muscle Energy Technique (MET)
- Developed by Fred Mitchell in 1948
- A form of manual therapy that uses gentle isometric contractions to relax muscles and lengthen them
- Active technique, where the patient is an active participant
Principles of MET
- Based on Autogenic Inhibition and Reciprocal Inhibition
- Autogenic Inhibition: relaxation of a muscle after a sub-maximal contraction
- Reciprocal Inhibition: contraction of one muscle followed by stretching of the opposite muscle
Types of MET
- Autogenic Inhibition MET:
- Post Isometric Relaxation (PIR)
- Post Facilitation Stretching (PFS)
- Reciprocal Inhibition MET:
- Contraction of one muscle followed by stretching of the opposite muscle
Post Isometric Relaxation (PIR)
- Developed by Karel Lewitt
- Technique to decrease muscle tone after a brief period of submaximal isometric contraction
- Works on the concept of autogenic inhibition
- Steps:
- Take the hypertonic muscle to a length just short of pain
- Perform a sub-maximal contraction away from the barrier for 5-10 seconds
- Relax and exhale, then apply a gentle stretch to take up the slack till the new barrier
Post Facilitation Stretch (PFS)
- Developed by Janda
- Technique based on autogenic inhibition
- Steps:
- Place the hypertonic and shortened muscle between a fully stretched and a fully relaxed state
- Contract the agonist using maximum effort for 5-10 seconds
- Relax and release the effort, then apply a rapid stretch to a new barrier and hold for 10 seconds
Reciprocal Inhibition MET
- Different from PIR and PFS in that it involves the contraction of one muscle followed by stretching of the opposite muscle
- Steps:
- Place the affected muscle in a mid-range position
- Push towards the restriction/barrier while the therapist resists (isometric) or allows movement (isotonic)
- Relax and exhale, then apply a passive stretch to the new barrier
Indications and Contraindications
- Indications:
- Lengthen a shortened, contractured, or spastic muscle
- Reduce pain
- Stretch tight fascia
- Reduce localized edema
- Enhance proprioception and motor control
- Improve local circulation
- Guard against future injuries
- Contraindications:
- Fracture
- Tendon ruptures
- Muscle Inflammation
- Acute sprains
- Acute strains
- Dislocations
- Precautions:
- Osteoporosis
- Hypermobility
