The purpose of this study was to investigate dissociative symptoms that may occur as an epiphenomenon of tactile-induced catalepsy. In 15 participants, catalepsy was induced in the right arm, and dissociative symptoms were evaluated using a self-report questionnaire. In comparison with the left, noncataleptic arm, the right cataleptic arm was perceived differently. In addition to increased rigidity, the cataleptic arm was characterized by the presence of paresthesias, a decreased perception of sense and a decreased awareness of the arm. Moreover, the self-reported changes in perception were significantly correlated to the hypnotically induced arm-immobilization part of the Stanford Hypnotic Susceptibility Scale. In conclusion, catalepsy induction elicits a variety of dissociative symptoms and provides a useful research paradigm for the study of motor-perceptual dissociative phenomena.
