The World Federation of Chiropractic comprises individuals and chiropractic associations in 85 countries, as voting and associate members. The WFC represents them and the chiropractic profession internationally.

The federation was founded in 1988. Since 1997 it has been an allied
non-governmental organization (NGO) with WHO, the World Health Organization. The WFC also collaborates with associations representing other healthcare professions.

The goals of the WFC, as quoted in the organization’s Articles and Bylaws, include:

• Acting with national and international organizations to provide information and other assistance in the fields of chiropractic and world health;
• Promoting uniform high standards of chiropractic education, research and practice;
• Developing an informed public opinion among all peoples with respect to chiropractic;
• Uniting members of the chiropractic profession and protecting the character and status of the profession.

The WFC defines chiropractic as follows:

A health profession concerned with the diagnosis, treatment and prevention of mechanical disorders of the musculoskeletal system, and the effects of these disorders on the functions of the nervous system and general health. There is an emphasis on manual treatments including spinal adjustment and other joint and soft-tissue manipulation.

As an organization concerned with spinal and musculoskeletal health, the WFC pursues a keen interest in evaluating and endorsing products that support this aspect of wellness.

The federation has endorsed the support features of the Nikken Kenko Sleep System, recognizing the Sleep System as a technology that promotes better sleep and physiologically beneficial skeletal support.
