What was the primary focus of Tuchin's study?

The primary focus of Tuchin's study revolved around assessing the changes in cortisol levels after spinal adjustments. This investigation is significant in the chiropractic field because it explores the physiological effects of spinal manipulation. Cortisol is a hormone associated with stress responses, and measuring its levels can provide insights into how chiropractic adjustments might influence stress and overall well-being. Such studies help substantiate the claims of chiropractic care by bridging the gap between clinical outcomes and biological markers, thus highlighting the potential health benefits of spinal adjustments beyond mere symptom relief.

This aspect of the study is crucial because it helps establish a scientific foundation for chiropractic practices, emphasizing that adjustments may contribute positively to not just mechanical issues but also to biological processes related to stress regulation.
