The McTimoney Chiropractic Association (MCA) currently claims to have around 400 members who represent at least a quarter of the UK chiropractic profession. This link to the Origin & History section of their website contains this statement : "Following his first heart attack, John McTimoney was asked to take on students in order to ensure the survival of his work…. McTimoney taught, as DD Palmer had before him, that health depends on healthy nerve messages, that subluxations of the vertebrae or other joints interfere with these, and that such subluxations can affect not only joints and muscles, but every cell and organ in the body". The Objectives section of the site states that "By correctly training the hands as an instrument of innate intelligence, healing can be encouraged to take place by the detection and correction of bony subluxations (slight displacements)". NOTE: Three of the ten chiropractors who have been elected to serve of the GCC's committees between June 2007-2012 are members of this organisation. (Names and locations of all UK chiropractors who are members of this organisation are available via this link)
