Scientific title | |
Study objectives | 1. To determine whether magnetic bracelets of 50mT field strength (at the ventral wrist-facing surface) are sufficiently convincing placebos for use in future trials of magnetic bracelets. The null hypothesis is that the proportion of people believing a bracelet is magnetic will be the same for people given (and allowed to test) 50mT and 180mT bracelets. 2. A secondary hypothesis relates to the difference in strength of belief that each type of bracelet may be therapeutic in relieving osteoarthritis pain. |
Ethics approval(s) | Added 21 July 2008: the study protocol and procedures were submitted to N&E Devon NHS Research Ethics Committee who considered that, as study design work conducted outside any NHS setting, the study did not require formal Committee approval. |
Health condition(s) or problem(s) studied | Musculoskeletal Diseases |
Intervention | Randomised controlled trial, comparing belief in magnetic status between 2 groups. |
Intervention type | Other |
Primary outcome measure | Added 21 July 2008: Based on the magnet assigned to the participant, responses to the question "Which kind of magnet do you think you have been given?" [Active /Inactive /Dont know]. |
Secondary outcome measures | Added 21 July 2008: Based on the magnet assigned to the participant, responses to the question How convinced are you that wearing this bracelet on your wrist for 3 months would help to relieve pain in your joints? [visual analogue scale from 0=Not at all to 10 = Totally convinced]. |
