Muscle Energy Technique (MET)

The Muscle Energy Technique (MET) is a Manual Therapy technique that was developed in 1948 by Fred Mitchell, Sr, D.O.

Muscle Energy Technique (MET) is a form of manual therapy commonly used by physical therapists, osteopaths, chiropractors, and other healthcare professionals to address musculoskeletal issues and improve joint function. It's a hands-on technique that involves the active and passive movement of a joint by the patient against a controlled resistance provided by the therapist.

The primary goal of MET is to restore normal function, flexibility, and strength to muscles and joints. It's based on the principle that the body has its own intrinsic ability to correct dysfunctions, and by engaging the patient in active movements, it encourages the body's own healing mechanisms.

Types of Muscle Energy Technique (MET)

Mainly Muscle Energy Technique is two types - 1. Autogenic Inhibition (MET) and 2. Reciprocal Inhibition (MET).
Autogenic Inhibition (MET) have another two subtypes Post Isometric Relaxation (PIR) and Post Facilitation Stretching (PFS).

1. Autogenic Inhibition (MET)

  • Post Isometric Relaxation (PIR)
  • Post Facilitation Stretching (PFS)

2. Reciprocal Inhibition (MET)

What is Autogenic Inhibition and Reciprocal Inhibition?

Autogenic Inhibition and reciprocal inhibition are two concepts related to the neuromuscular system and how muscles respond to different stimuli, particularly in the context of muscle relaxation and contraction.

1. Autogenic Inhibition:

Autogenic inhibition refers to the process where the muscle relaxes in response to its own tension or contraction. It involves the activation of Golgi tendon organs (GTOs), which are specialized sensory receptors located in the tendons where muscles attach to bones. These GTOs are sensitive to changes in muscle tension.

   When a muscle contracts forcefully, the GTOs are stimulated, sending signals to the spinal cord to inhibit the motor neurons that are causing the muscle to contract. This inhibition mechanism is a protective reflex to prevent excessive force or tension within the muscle. Autogenic inhibition helps in muscle relaxation and preventing injury by limiting the muscle's contraction strength when it reaches high tension levels.

   Autogenic inhibition is often utilized in various relaxation and stretching techniques where the muscle is contracted briefly and then relaxed, taking advantage of this reflex to enhance muscle lengthening and relaxation.

2. Reciprocal Inhibition:

Reciprocal inhibition involves the simultaneous relaxation of one set of muscles while the opposing muscles are contracting. It is mediated by the nervous system's reflex mechanism to facilitate coordinated movement and prevent muscles from working against each other.

   When a muscle contracts, its antagonist (opposing muscle) tends to relax. This relaxation occurs through the inhibition of the antagonist's motor neurons via signals from the spinal cord. For example, when you bend your elbow, the biceps muscle contracts (agonist), and the triceps muscle relaxes (antagonist) to allow smooth movement.

   Reciprocal inhibition is crucial for coordinated and efficient movement patterns, allowing for smooth and controlled joint movements by ensuring that opposing muscles don’t contract simultaneously and oppose each other's actions.

What is Post Isometric Relaxation (PIR) and Post Facilitation Stretching (PFS)?

1. Post-Isometric Relaxation (PIR):

Karel Lewitt developed the technique known as Post-Isometric Relaxation (PIR), which describes the reduction in muscle tone in a single muscle or a muscle group following a brief period of submaximal isometric contraction of the same muscle.

   - PIR is a technique used in manual therapy and muscle energy techniques to enhance muscle flexibility and improve range of motion. It involves a sequence of muscle contractions followed by relaxation and passive stretching.

   - The process typically starts with the patient actively contracting a specific muscle or muscle group against resistance provided by the therapist. This is an isometric contraction, meaning the muscle length remains constant while tension is generated.

   - After holding the isometric contraction for several seconds, the muscle is then relaxed. The relaxation phase aims to take advantage of the body's autogenic inhibition reflex, which leads to the temporary relaxation of the muscle due to the activation of Golgi tendon organs (GTOs) in the tendons.

   - Following the relaxation phase, the therapist passively stretches the muscle. The relaxation achieved during the previous contraction can make the muscle more responsive to stretching, potentially allowing for greater gains in muscle length and improved flexibility.

2. Post-Facilitation Stretching (PFS):

Developed by Janda, Post-Facilitation Stretch (PFS) represents a more assertive technique compared to PIR, yet it also operates on the principle of autogenic inhibition.

   - PFS is a similar concept used in manual therapy and muscle facilitation exercises, particularly following facilitated muscle contractions or exercises. It involves stretching the targeted muscle or muscle groups after they have been actively engaged or facilitated.

   - The process includes first facilitating or activating the targeted muscle through contractions or resisted movements. This facilitation phase aims to enhance muscle responsiveness to subsequent stretching.

   - After the muscle has been facilitated or activated, it is then stretched gently and gradually. The goal is to take advantage of the increased muscle pliability and decreased resistance to stretch that result from the prior muscle activation.

Both PIR and PFS aim to optimize the gains in muscle length and flexibility that can occur after controlled muscle contractions or facilitation. These techniques are employed to enhance the effectiveness of stretching and promote improved range of motion in individuals experiencing muscle tightness or restricted movement.

Physiology of Muscle Energy Technique (MET)

The physiology behind Muscle Energy Techniques (MET) involves several neurological and biomechanical mechanisms that influence muscle function, joint mobility, and the body's responses to manual therapy. Here's an overview of the physiological aspects involved in MET:

Neuromuscular Control:

   Autogenic Inhibition: MET utilizes the principle of autogenic inhibition, which involves the Golgi tendon organs (GTOs) located in the tendons. These sensory receptors detect changes in muscle tension. When a muscle is contracted against resistance, the GTOs are activated, leading to inhibitory signals sent to the spinal cord. This inhibition causes the muscle to relax, allowing for increased flexibility and reduced tension.
   Reciprocal Inhibition: Another principle used in MET involves reciprocal inhibition, where the contraction of one muscle results in the relaxation of its antagonist (opposing) muscle. This mechanism aids in coordinating movements and preventing muscles from working against each other.

Stretch Reflex and Muscle Lengthening:

   - By engaging in specific contractions followed by relaxation, MET takes advantage of the stretch reflex. This reflex occurs when a muscle is stretched, leading to the activation of muscle spindles, which detect changes in muscle length. The subsequent reflexive contraction helps protect the muscle from being overstretched.

   - This reflex mechanism can be manipulated in MET to encourage muscle relaxation after a contraction, allowing for greater muscle lengthening and increased range of motion.

Enhanced Blood Flow and Tissue Healing:

   - The repetitive contraction and relaxation cycles in MET can increase blood flow to the targeted muscles and tissues. Improved circulation helps deliver oxygen and nutrients to the area, aiding in tissue healing and repair.

Neuromuscular Re-Education and Motor Control:

   - MET contributes to neuromuscular re-education, helping the body re-establish optimal movement patterns. Through controlled contractions and relaxation techniques, MET can improve motor control, muscle strength, and coordination.

Pain Modulation:

   - MET techniques may help modulate pain by promoting muscle relaxation, reducing muscle tension, and enhancing tissue flexibility. This can contribute to decreased discomfort and improved function in individuals experiencing musculoskeletal pain.

Indications of Muscle Energy Techniques (MET)

The indications for using Muscle Energy Techniques (MET) includes:

1. Muscle Tightness and Imbalances: MET can be employed to address muscle tightness, spasms, and imbalances that contribute to restricted range of motion, postural abnormalities, and movement dysfunction.
