Visceral Manipulation (VM) was developed by world-renowned French Osteopath and Physical Therapist Jean-Pierre Barral. Comparative Studies found Visceral Manipulation Beneficial for Various Disorders:

Whiplash, Seatbelt, Chest or Abdominal trauma
Digestive disorders: Bloating, Constipation, IBS, Acid Reflux
Musculoskeletal disorders: Headaches, Migraines, Spinal disorders, Carpal Tunnel Syndrome, Sciatica
Women's Health: Cysts, Prolapse, Incontinence, Pelvic Pain, Sexual dysfunction, Effects of Menopause
Pediatric issues: Colic, Reflux, Constipation, Speech issues, Sleep disturbances

VM assists functional and structural imbalances throughout the body including musculoskeletal, vascular, nervous, urogenital, respiratory, digestive and lymphatic dysfunction. It evaluates and treats the dynamics of motion and suspension in relation to organs, membranes, fascia and ligaments. VM increases proprioceptive communication within the body, thereby revitalizing a person and relieving symptoms of pain, dysfunction, and poor posture.
