Who is recognized for developing the spinal cord compression hypothesis through the HIO technique?

The development of the spinal cord compression hypothesis through the HIO (Hole in One) technique is attributed to BJ Palmer. BJ Palmer, known as the developer of chiropractic, made significant contributions to the field, particularly in the refinement of chiropractic principles and techniques. The HIO technique focuses on specific adjustments aimed at the upper cervical spine, particularly the atlas vertebra, to relieve pressure on the spinal cord. This approach reflects BJ Palmer's emphasis on the relationship between spinal misalignments and neurological function, which is a core aspect of chiropractic philosophy. His work laid the foundation for understanding how spinal adjustments can influence overall health, making him a pivotal figure in the evolution of chiropractic practices.
