Pantelis Xenophontos

Pantelis qualified from the British School of Osteopathy with a Master’s degree in Osteopathy.

In addition to this, Pantelis has a Sports Massage diploma and is trained in Medical Acupuncture.

Pantelis has a sports background as he grew up playing football at a semi-professional level, and he thrives in the gym environment as he is able to work very closely with personal trainers. He also trained with British champions in the Escrima Philippino martial art system for four years.

His treatment utilises a structural approach involving massage, manipulation, mobilization, neuromuscular techniques, medical acupuncture and rehabilitation exercises. The treatment is tailored to each individual and is supported with advice on posture, lifestyle, nutrition and exercise. This clinical advice aims to help his patients understand the nature of their problems so that they can return to their everyday activities as soon as possible, and prevent further injury.

Pantelis treats many people suffering from work-related injuries. Occupational injuries can be caused by poor ergonomics, manual handling of heavy loads, misuse or failure of equipment, repetitive movements, and particularly, unsuitable posture. He can advise on correct posture and back care and also recommend preventative exercises.

Pantelis is a member of the General Osteopathic Council (GOsC), British Osteopathic Association (BOA) and the Osteopathic Sports Care Association (OSCA).

About Applied Kinesiology

Applied kinesiology (AK) is a form of diagnosis using muscle testing as a primary feedback mechanism to examine how a person’s body is functioning. When properly applied, the outcome of an AK diagnosis will determine the best form of therapy for the patient.

In general, the applied kinesiologist finds a muscle that tests weak and then attempts to determine why that muscle is not functioning properly. The practitioner will then evaluate and apply the therapy that will best eliminate the muscle weakness and help the patient.

Therapies utilized can include specific joint manipulation or mobilization, myofascial therapies, cranial techniques, meridian therapy, clinical nutrition, dietary management and various reflex procedures.

A Brief History of AK

The use of manual muscle testing to evaluate body function was introduced by George Goodheart D.C. (Doctor of Chiropractic) in 1964. Since then, research into and knowledge of AK has expanded considerably, providing many additional dimensions to the diagnosis of bodily dysfunction.

Even in the early days of AK, it was apparent how the use of many treatment methods in Osteopathy, Chiropractic, Acupuncture and Homeopathy produced improved neuromuscular function which could be directly measured using manual muscle testing.

The Triad of Health

Applied kinesiology uses the triad of health – chemical, mental and structural factors – to describe the proper balance of the major health categories.

The triad is represented by an equilateral triangle with structural, chemical and mental health representing the three sides. When a person experiences poor health, it is due to an imbalance in one or more of these three factors.

The triad of health is interactive and all aspects must be evaluated for the underlying cause of a problem. A health problem on one side of the triad can affect the other sides. For example, a chemical imbalance may cause mental symptoms. Applied kinesiology enables the practitioner to evaluate the triad’s balance and direct therapy toward the imbalanced side or sides.

Conditions Treated

Any basic structural defects for which any person may visit a healthcare practitioner e.g.:

neck pain
back pain
headaches and migraine
postural abnormalities
disc injuries
nerve root irritation
acute onset and sports injury

In addition, an AK practitioner will address many other functional and systemic disorders from which people increasingly suffer in modern day society, including:

stress related disorders
childhood disorders
hormone related disorders
digestive problems
sleep pattern disorders

What to Expect During an AK Treatment

The practitioner will take a full and detailed history. They will then perform a wide variety of muscle tests on the patient in order to establish areas of dysfunction.

The great advantage of AK is that the practitioner no longer needs to rely entirely on chemicals or invasive technology to treat the patient. AK provides a system whereby the practitioner works with the patient and the patient is able to be actively involved in their treatment and has an immediate source of feedback through muscle testing. In this way, the patient is able to adopt a much greater sense of responsibility towards their health, and can have a greater awareness of any dysfunction present.

When visiting an AK Practitioner, expect to be involved. They will test for basic mechanical defects; the possible connection of visceral dysfunction (that is, the function of the associated gland or organ); stress levels in the body; and, where relevant, cranial and pelvic distortion and toxicity / allergy problems.

Treatment may involve any combination of manipulative work, guidance in self-treatment, nutritional support, homeopathic remedies and treatment to aid stress-related problems.
