Release
Release: In rehabilitation, performance, and manual therapy settings, release generally refers to the feeling of a reduction in tissue tone, tension, density, or activity in response to pressure, position, vibration, mobilization, or manipulation of soft tissue. The mechanism that results in a feeling of "release" is likely a complex set of mechanical changes and neuromuscular reflexes; (for example, depicted in the Schleip Model of Tissue Manipulation) however, it is assumed that "autogenic inhibition" plays the most considerable role, as a result of stimulating Golgi tendon organ, Ruffini endings and/or Pacinian corpuscles.
