What is Osteopathy?
Osteopathy involves clinical care of the neuro-musculoskeletal system, which is made up of the bones, muscles, nerves and other tissues that support your body and control its movements.
Osteopaths use your individual medical history and environmental factors to understand the root cause of your pain to develop a personalised plan to help you manage your pain and move better.
Mr Xenophontos offers Osteopathic treatment which may involve any combination of Manual Therapy (manipulation, mobilisation, or neuromuscular techniques, soft tissue massage), Therapeutic Needling Techniques and Clinical Exercise Program. The treatment is tailored to each individual and is encouraged through advice on posture, lifestyle and aid to stress-related problems. This clinical advice aims to help patients understand the nature of their problems so that they can return to their everyday activities as soon as possible.
