This document discusses muscle energy technique (MET), a manual therapy procedure that involves voluntary muscle contraction against resistance applied by a therapist. It describes the types of muscle contractions involved - isotonic, eccentric, concentric, and isometric. MET uses post-isometric relaxation and reciprocal inhibition to facilitate muscle lengthening. Indications for MET include acute muscle spasm and restricted joints, while contraindications are acute injuries and unstable joints. Benefits of MET include restoring normal muscle tone, strengthening weak muscles, and improved joint mobility. Guidelines are provided for safely applying light contractions over multiple repetitions.

3. MUSCLE ENERGY
TECHNIQUE
Muscle energy technique is a manual
therapy procedure which involves the
voluntary contraction of a muscle in a
precisely controlled direction at varying
levels of intensity against a distinct counter
force applied by the therapist.

4. Types of Contraction
Types of
Contraction

Eccentric

Concentric

5. Types of Contraction
Isometric

Isotonic contraction

6. Isotonic contraction Isometric contraction

7. It is a type of muscle contraction in which the
muscles shorten while generating force. This
occurs when the force generated by the muscle
exceeds the load opposing its contraction
the muscle elongates while under tension due to
an opposing force greater than the muscle force.
Concentric contraction-
Eccentric contraction-

8. Post
isometric
relaxation
(PIR)
Reciprocal
inhibition

9.  When an agonist muscle contracts and shortens,
its antagonist must relax and lengthen so that
motion can occur under the influence of the
agonist muscle.
 The contraction of the agonist reciprocally inhibits
its antagonist allowing smooth motion.
 The harder the agonist contracts, the more
inhibition in the antagonist, causing relaxation
Reciprocal inhibition

12. Post-isometric relaxation

13. APPLICATION OF THE
TECHNIQUES
Isotonic contraction using Post-Isometric Relaxation
Isotonic contraction using Reciprocal Inhibition

14. • Indication – 1.acute muscular spasm or
2.to mobilise a restricted joint
 Procedure - The therapist takes the agonist
muscle to its barrier position; then ask the patient
to contract muscle then therapist apply equal
resistance to the patients contracting the agonist
muscle , for 7-10 seconds. Patient relaxes for
around 5 seconds, and then as they exhale, the
therapist takes muscle to the new restriction
barrier, and the process is repeated 3 to 5 times.
Isotonic contraction using Post-Isometric
Relaxation

15.  Indication -condition of chronic, fibrotic muscular
spasm.
 In this tech. we have to apply same procedure as
PIR. The difference is that we have to target
antagonistic muscle.
Isotonic contraction using Reciprocal Inhibition

16.  Lengthen shortened, contracted muscle.
 Spasticity.
 Strengthen weak muscle or group of muscles.
Indications of MET:

17.  Acute musculoskeletal injuries
 Unset or unstable fracture
 Unstable or fused joints
Contraindications of MET:

18.  Restoring normal tone in hypertonic muscles.
 Strengthening weak muscles.
 Preparing muscle for subsequent stretching.
 Improved joint mobility.
The benefits of MET

19. • No pain should be caused by MET.
• Keep contractions light (20-30% of strength)
• Communicate effectively and ensure client is
not experiencing discomfort.
• Never over-stretch.
