This chapter presents a case study of a sensorimotor psychotherapy (SP) approach to eating disorder (ED) treatment. In contrast to traditional psychotherapeutic approaches, such as cognitive behavioral therapy (CBT), dialectical behavior therapy (DBT), and acceptance and commitment therapy (ACT), that lean heavily on the impact of thoughts on emotional experiences and somatic patterns, also known as top-down processing, SP also uses bottom-up processing, the effect that one’s somatic organization has on affect and affect regulation, cognitive functioning and specific beliefs about self and other. The very core of SP is four foundational principles that cultivate therapeutic presence and guide both content and quality of interventions: organicity, nonviolence, unity, body/mind/spirit holism. SP understands human experience through the lens of five core organizers: thoughts, emotions, and three somatic organizers. SP explores actions as a cycle with four stages: clarity, effectiveness, satisfaction, and relaxation.
