The quality of placebos used in randomized, controlled trials of lumbar and pelvic joint thrust manipulation - a systematic review.. "Imperfect placebos are ubiquitous in clinical trials of LP-SMT and few trials have assessed for successful subject blinding or balanced expectations of treatment success between active and control group subjects. There is thus a strong potential for unmasking of control subjects, unequal non-specific effects between active and control groups, and non-inert placebos in existing trials."
