Who is credited with originating the spinal cord compression hypothesis through research and the HIO technique?

The correct answer is BJ Palmer, who is credited with originating the spinal cord compression hypothesis through his research and development of the HIO (Hole-In-One) technique. BJ Palmer, often referred to as the "Developer" of chiropractic, built upon the foundations laid by his father, DD Palmer, and advanced chiropractic theory and practice significantly.

BJ Palmer's work focused on the concept that misalignments in the vertebrae could lead to compression of the spinal cord, thereby affecting nerve function and health. His research emphasized the role of specific vertebral subluxations in producing neurologic effects that could contribute to disease or dysfunction. The HIO technique emerged from this understanding, aimed at correcting specific misalignments in the upper cervical spine to restore proper nerve function.

This approach revolutionized chiropractic practice, providing a scientific basis for spinal adjustments and highlighting the importance of the spinal cord in overall health. BJ Palmer's contributions not only shaped chiropractic techniques but also helped establish a stronger scientific legitimacy for the profession as a whole.
