Flotation-REST (reduced environmental stimulation therapy) alters the balance of sensory input by systematically attenuating signals from the visual, auditory, thermal, tactile, vestibular, and proprioceptive systems. Previous research has shown that this heightens interoceptive awareness and reduces anxiety in clinically anxious populations. Anorexia nervosa (AN) is characterized by elevated anxiety, distorted body image, and disrupted interoception, raising the question of whether floatation therapy might positively impact these symptoms. A recent safety study found that Floatation-REST was well tolerated by individuals weight-restored outpatients with current or prior AN. Additionally, participants reported improvements in affective state and body image disturbance following floating, raising the possibility that this intervention might be investigated for clinical benefit in more acutely ill cases.~The primary aim of this study is to begin to examine the effect of Floatation-REST on body image disturbance in inpatients with AN. Secondary aims including determining whether Floatation-REST has an impact on anxiety, emotional distress, eating disorder severity, functional ability, and interoception.
The study proposed in this protocol aims to document the effect of Floatation-REST (reduced environmental stimulation therapy) on symptoms of anorexia nervosa.
