Rubber Hand Illusion Induced by Electronic Equipment-Controlled Stimuli
Main Article Content
Abstract
The induction of rubber hand illusion (RHI) is typically manually performed by brushes. In this direction, we developed an electronic device in order to increase the accuracy of tactile stimuli in RHI. Objective: To determine the effectiveness of an electronic and programmable apparatus developed for induction of RHI. Method: The study included 51 participants, age (11 and 59 years) distributed in four groups. For data collection we used the prosthetic hands and the personaly developed electronic equipment. The intensity of RHI was assessed using a subjective questionnaire containing 13 questions ranked in agreement or disagreement on the sensations perceived paradigm. Results: We found significant effects on all questions about incorporation of the rubber hand. Conclusion: The electronic equipment was effective in speed, timing and accuracy of movement of brushes and displayed the robust induction of RHI. Hence, we propose the use of such eletronic equipment in the RHI paradigm in scientific studies.
