Muscle Energy Techniques (MET) are gentle, safe, and highly effective methods widely used by physiotherapists, sports therapists, and rehabilitation specialists. These techniques involve the active participation of the patient, where controlled muscle contractions are combined with precise positioning and therapist guidance. For therapists, MET provides a non-invasive approach to improve joint mobility, reduce muscle tightness, and correct postural imbalances. Unlike aggressive manipulations, these techniques respect the natural limits of the body and work through cooperation between the therapist and the patient.
