Dr Peter Grainger DHom DMedH ASHAT - Clinical Practitioner:

Peter is a clinical hypnotherapist and he routinely uses the Alpha-Active HeadCoach™ EEG during his clinical work.

Trained in hypnosis in the NHS, Peter used it to treat patients with chronic pain. Currently he offers a form of hypnotherapy which involves monitoring the brain's electrical activity (EEG) to ensure that the therapy becomes effective in the quickest possible time. Use of the EEG during therapy provides a measure of the patient's state of mental awareness/consciousness.

Dr Grainger uses hypnosis and EEG in the treatment of many conditions such as addictions like smoking or alcohol, for weight loss, or to gain confidence, or for conditions such as chronic pain, phobias, post-traumatic stress disorder, irritable bowel syndrome and any stress related problem such as anxiety/tension, insomnia, high blood pressure, panic attacks, guilt, anger, jealousy and inadequacy can be helped.
