I found this definition through google. I had no idea what it was but now I'm interested! Hope it helps you...
Sensorimotor Psychotherapy is a body-centred psychotherapy that makes it possible for clients to discover the habitual and automatic attitudes, both physical and psychological, by which they generate patterns of experience. This gentle therapy teaches clients to follow the inherently intelligent processes of body and mind to promote healing. It is particularly helpful in working with the effects of trauma and abuse, emotional pain, and limiting belief systems. Through the use of simple experiments, unconscious attitudes are brought to consciousness where they can be examined, understood, and changed. A synthesis of somatic therapy and the Hakomi Method of Body-Centred Psychotherapy developed by Ron Kurtz in the 1980's, and from which it evolved, Sensorimotor Psychotherapy has gained international acclaim.
