Is blinding in studies of manual soft tissue mobilisation of the back possible? A feasibility randomised controlled trial with Swiss graduate students - Chiropractic & Manual Therapies

January 31, 2024

By nature of the intervention, intervention providers could not be blinded to intervention assignment, but were kept in a separate room. Possible responses were: ‘I strongly believe that I received the active intervention’, ‘I somewhat believe that I received the active intervention’, ‘I somewhat believe that I received the control intervention’, ‘I strongly believe that I received the control intervention’, and ‘I do not know’. Data were collected by asking outcome assessors: ‘To what extent do you know which intervention (active intervention or control intervention) the participant received?’. Possible responses were: ‘I strongly believe that they received the active intervention’, ‘I somewhat believe that they received the active intervention’, ‘I somewhat believe that they received the control intervention’, ‘I strongly believe that they received the control intervention’, and ‘I do not know’. To address the primary objective of the trial, blinding was analysed following an intention-to-treat approach.
