There are numerous branches of body psychotherapy, often tracing their origins to particular individuals: for example, 'Bioenergetic analysis' to the work of Lowen and Pierrakos; 'Radix' to the work of Chuck Kelley; Organismic Psychotherapy to the work of Malcolm and Katherine Brown; 'Biosynthesis' to the work of David Boadella; 'Biodynamic Psychology' to that of
Gerda Boyesen; 'Rubenfeld Synergy' to Ilana Rubenfeld's work; 'Body-Mind Centering' to Bonnie Bainbridge Cohen's work, and 'Body-mind Psychotherapy' to Susan Aposhyan; the development of Jack Painter's 'Postural and Energetic Integration' into a psychotherapeutic modality. Many of these contributors to body psychotherapy were influenced by the work of Wilhelm Reich, while adding and incorporating a variety of other influences. Syntheses of these approaches are also becoming accepted and recognised in their own right (e.g. The Chiron Approach: Chiron Association of Body Psychotherapists). Alongside the body psychotherapies built directly on the work of Reich, there is a branch of post-Jungian body psychotherapies, developed from
Jung's idea of the 'somatic unconscious'. While many post-Jungians dismiss Reich and do not work with the body, contributors to Jungian derived body psychotherapy include
Arnold Mindell with his concept of the 'dreambody' and the development of
process oriented psychology. Body psychotherapy and dance movement therapy have developed separately and are professionally distinguished, however they have significant common ground and shared principles including the importance of non-verbal therapeutic techniques and the development of body-focused awareness. The review reports that one of the strongest studies is longitudinal (2 year) outcome research conducted with 342 participants across 8 different schools (Hakomi Experiental Psychology, Unitive Body Psychotherapy, Biodynamic Psychology, Bioenergetic Analysis, Client-Centred Verbal and Body Psychotherapy, Integrative Body Psychotherapy, Body-Oriented Psychotherapy, and Biosynthesis). Overall efficacy was demonstrated in symptom reduction, however the study design limited further substantive conclusions. The review of outcome research across different types of body-oriented psychotherapy concludes that the best evidence supports efficacy for treating somatoform/psychosomatic disorders and schizophrenia, while there is also support for 'generally good effects on subjectively experienced depressive and anxiety symptoms, somatisation and social insecurity.' A more recent review found that results in some of these domains were mixed or might have resulted from other causes (for example, somatic symptoms in one study improved even after therapy had ended, suggesting that the improvements may have been unrelated to the therapy). ==Trauma==
