Based on the hypothesis that it is possible for a stutterer to pull out of difficulty during a moment of stuttering, this term refers to a voluntarily controlled, gradual, release from the stuttering moment. In pulling out of blocks, the stutterer does not let the original blocking run its course. Instead he makes a deliberate attempt to modify it before the release occurs and before the word is spoken. This procedure is called in-block correction by some clinicians.
