Five-item questionnaire derived from (Longo et al., 2008a; Jenkinson et al., 2013) to probe subjective aspects of the RHI.

Rubber Hand Illusion Questionnaire
(1) How much does it seem that the touch you are feeling is where you see the rubber hand being stroked?
(2) How much does it seem as if you might have more than one left hand?
(3) How much does it seem as though the rubber hand is your hand?
(4) How much does it seem as though you are losing the sense of where your own hand is?
(5) How much does it seem as though you are losing the sense of owning your hand?

Subjects respond with a number from 0 to 6 in response to the question, with lower numbers indicating negative responses and greater numbers indicating positive responses. Study hypotheses focused on TC practitioner responses to the tactile (Q1), ownership (Q3), and proprioceptive (Q4) questionnaire items.
