Muscle Energy Technique
Muscle Energy Technique (MET) is a hands on therapy that uses controlled muscle contractions to improve joint function, reduce pain and increase flexibility. At Physical Therapy Associates we use MET to help patients recover from injuries, reduce muscle tightness and restore natural movement. During MET our therapist will guide you through gentle muscle contractions while applying resistance so your muscles can engage and release in a way that promotes alignment and healing.
What is MET
MET is a type of manual therapy that combines muscle contractions with gentle resistance to address issues such as joint misalignment, muscle tension and restricted movement. By contracting the muscles against light resistance from the therapist using muscle force, MET corrects muscle imbalances, improves joint mobility and reduces pain. This technique is often used in physical therapy to help patients with conditions that affect flexibility and alignment.
Definition and Purpose
Muscle Energy Technique (MET) is a specialized form of manual therapy that uses the patient’s own muscle energy to achieve the therapeutic goals. By engaging the muscles in controlled contractions MET relaxes and lengthens the muscle tissue thereby improving joint mobility and reducing pain. The purpose of MET is to address somatic dysfunction which includes decreased range of motion, muscular hypertonicity and pain. This energy technique is designed to restore normal muscle function, reduce muscle tension and promote relaxation making it a versatile tool in manual therapy.
Benefits of MET include post isometric relaxation:
Increased joint mobility and range of motion
Reduced muscle tightness and discomfort
Increased flexibility and relaxation
MET is good for those with muscle stiffness, alignment issues and joint pain. The relaxation of the agonist muscle during MET allows the antagonist muscle to contract more effectively.
Physiology of Muscle Energy
Muscle energy is the force generated by the contraction and relaxation of muscle fibers. When a muscle contracts it produces force that can be used to move joints and maintain posture. But when a muscle becomes shortened or over contracted it can cause somatic dysfunction which manifests as decreased range of motion and pain. Muscle Energy Technique (MET) uses the principles of post isometric relaxation and reciprocal inhibition to enhance musculoskeletal function and reduce discomfort. By understanding and using these natural processes MET addresses muscle tension and joint mobility issues.
How MET works
The mechanism of Muscle Energy Technique (MET) is the strategic use of muscle contractions to improve joint mobility and reduce pain. When a muscle contracts it activates the Golgi tendon organs (GTOs) which are sensory receptors that detect changes in muscle tension. The GTOs send a signal to the spinal cord which triggers a response that inhibits the muscle contraction and promotes relaxation – a process called post isometric relaxation. MET also uses the principle of reciprocal inhibition where one muscle group contracts and the opposing muscle group relaxes. These mechanisms work together to reduce muscle tension and improve joint function making MET a effective therapy.
Autogenic and Reciprocal Inhibition
Autogenic and reciprocal inhibition are the two main principles in the application of Muscle Energy Technique (MET). Autogenic inhibition is when a sub-maximal contraction of a muscle is followed by stretching of the same muscle. This is mediated by the Golgi tendon organs (GTOs) and muscle spindles which sense changes in muscle tension and length. Reciprocal inhibition is when one muscle group contracts and the opposing muscle group stretches. This is mediated by the spinal cord and involves the activation of inhibitory interneurons. By using these physiological responses MET reduces muscle tension and increases flexibility and overall musculoskeletal health.
What is the difference between MET and PNF?
MET and Proprioceptive Neuromuscular Facilitation (PNF) both increase flexibility and reduce tension but:
Muscle Energy Technique (MET): Involves voluntary muscle contractions against light resistance from the therapist to correct joint alignment and increase flexibility.
Proprioceptive Neuromuscular Facilitation (PNF): Uses a series of stretches and contractions to increase flexibility and muscle strength, often more intense than MET.
MET is a gentler approach for alignment and mild muscle tension, PNF is used in rehabilitation settings for strength and flexibility. Both are useful but used based on patient needs.
How long to hold Muscle Energy Technique?
In MET the isometric contraction is held for about 3-10 seconds before relaxing. The therapist will guide you through a series of contractions and releases, each one tailored to your tolerance and condition. This allows for effective muscle activation without over exertion and maximizes the benefits of each contraction relaxation cycle. Timing is key in MET to ensure the muscles are activated and relaxed correctly for relief and mobility improvement.
What are the names of Muscle Energy Techniques?
There are several MET’s, each for different therapeutic goals:
Post-Isometric Relaxation (PIR): To relax the muscle after contraction to release tension and increase flexibility.
Reciprocal Inhibition (RI): To contract the opposing muscle to relax the target muscle to reduce spasms and tightness.
Joint Mobilization MET: To apply MET to mobilize specific joints, to align and move without pain. The extensor reflex is involved in stabilizing the body during MET by contracting one muscle group to inhibit its contralateral counterpart in response to stimuli.
Each one is chosen based on the patient’s needs, whether it’s to reduce tension, correct joint alignment or increase flexibility.
