NCT02578420 · Status: COMPLETED · Phase: NA · Type: INTERVENTIONAL · Enrollment: 160

Last updated 2017-07-26

No results posted yet for this study

Summary

To date, very little is known about the mechanisms of open-label placebo treatment and there is a lack in highly controlled experimental designs. Therefore, the planned project will test well-established explanatory models of (deceptive) placebo, i.e., (1) expectancy, (2) meaning response, in an open-label placebo design, investigating their influence on placebo analgesia.
