Hypnosis is an externally induced alteration in consciousness through suggestion, and hypnotherapy uses it as a psychological treatment for pain relief, habit modification, and various mental and physical health conditions. The method described involves muscle relaxation, suggestion, and sensory deprivation, with rapid induction of catalepsy by moving the person's limbs to stimulate the kinesthetic system. Hypnotizability varies with personal characteristics, and contraindications include psychosis, especially schizophrenia with delusions of influence, and prominent histrionic traits. Electroencephalogram changes during hypnotic catalepsy show increased delta rhythm power, increased theta rhythm amplitude and index in temporal leads, and significant hemispheric asymmetry, indicating a state distinct from sleep and wakefulness.
