This comprehensive text describes the basis and practice of Muscle Energy Techniques (MET), a widely recognized approach to treating musculoskeletal dysfunction. It describes those manipulative techniques in which a patient, on request, actively uses his or her muscles from a controlled position in a specific direction against a distinct counterforce applied by the practitioner. These techniques are combined from methods used in physical therapy, osteopathy, chiropractic and manual medicine. A companion DVD-ROM includes video clips demonstrating the application of techniques.
