Research has consistently demonstrated a connection between affect dysregulation and experiences of early childhood neglect, trauma, and attachment failure (Courtois & Ford, 2009; Ford, Courtois, Steele, van der Hart, & Nijenhuis, 2005; Siegel, 1999; Van der Kolk, 2015). Without adequate regulation of infant distress states, the autonomic nervous system and affect-regulating brain structures fail to develop optimally (Schore, 2003). Affect dysregulation is a component of all mood disorders, anxiety disorders, posttraumatic stress disorder, and borderline personality disorder as well as a contributor to addictive, self-injurious, and suicidal behavior. Methods to increase self-regulation are crucial to the effectiveness of any treatment for these issues. Traditional therapeutic modalities that address distorted cognitions, focus on emotional expression, or expose individuals to traumatic memories often fail to modify autonomic dysregulation in response to present day experience. Sensorimotor Psychotherapy (Ogden & Fisher, 2016; Ogden, Minton, & Pain, 2006), a somatically oriented talking therapy, approaches affect dysregulation as a subcortical physiological issue central to the treatment of traumatic stress.
