Harmonic Technique is a classical osteopathic technique which has been 'rediscovered',researched and further developed for use in modern practice by Eyal Lederman.

In the last two decades extensive research has demonstrated the importance of passive motion for repair processes in acute and chronic musculoskeletal conditions.

Harmonic Technique is characterised by passive motion, which can be applied to different areas of the body. These techniques are used to assist and direct repair processes in the body using a gentle non-painful and non-traumatic treatment approach.
