Summary

There is marked uncertainty regarding the feasibility of achieving adequate blinding in randomized controlled trials of manual therapy. In other words, whether participants and outcome assessors can accurately perceive randomly assigned interventions is unclear. This feasibility trial was conducted as part of a doctoral epidemiology course at the University of Zurich, Switzerland. Within the practice-based context of the class and using a study population of healthy graduate students enrolled in the course, the investigators aimed to evaluate blinding of participants randomly assigned (similar to tossing a coin) to one of two manual therapy interventions (active versus control). The investigators also aimed to assess blinding among outcome assessors.
