A Comparison of the Immediate Effects of Chiropractic Thoracic High-Velocity Low-Amplitude Manipulation Applied Supine and Prone on the Autonomic Nervous System
Abstract
Thoracic manipulation is one of the spinal manipulative treatment methods frequently used by clinicians. However, when carrying out this task, several methods could be preferred. This study aimed to compare the immediate effects of supine and prone thoracic high-velocity-low-amplitude chiropractic manipulations on the autonomic nervous system. The study included 62 healthy and volunteer participants aged 18-45 years. Participants were randomly assigned to supine and prone manipulation groups. Both groups, heart rate variability data were obtained with the Elite HRV CorSense device for 1 minute before the application, systolic and diastolic blood pressures were measured, pulse and saturation values were recorded. After the measurement, supine chiropractic manipulation was applied to the mid-thoracic region and the same measurements were repeated. Heart rate variability data were analyzed with Elite HRV application, pulse rate, saturation, systolic and diastolic blood pressure values were recorded, and the results were statistically evaluated. In the intra-group comparison, LF/HF ratio increased in the prone group (p=0.025). When the difference between the groups was analyzed, the change in LF/HF ratio was found to be statistically significant between the two groups (p=0.008). The effect of prone application on the autonomic nervous system was found to be higher than supine application. This study revealed that prone and supine thoracic chiropractic HVLA application was effective on OSS in healthy individuals and that the efficiency of prone manipulation was significantly higher.
