Introduction to research page 2

Welcome to Dr. Hart's research, page 2. Please see Research-1 page for explanation on how Dr. Hart uses resting heart rate (RHR) and heart rate variability (HRV) in his practice to check the neurological progress of his patients. 


Study #14 - Another study by Dr. Hart published - on the optimal level of HRV for spinal adjustment

This study on patients at Hart Chiropractic revealed  that there is an optimal amount of HRV  for adjusting the patient in order for the patient to experience a neurological benefit from the adjustment.  Here is the citation: 

Hart J. Optimal level of heart rate variability for spinal adjustment: A case report. Journal of Contemporary Chiropractic 2019; 2(1): 103-108. Article link where open access full text PDF is available:


Study #15 - Another new patient not needing an adjustment

This case report is similar to Case Study #12 (on Research-1 page), who was also a new patient not needing a spinal adjustment.

Here is the patient's data:

Visit        RHR      HRV

1                 62.2        57.5         

2                48.9       106.9

The patient called a few weeks later and indicated his symptoms were gone. No spinal adjustment was needed since the heart rate tests showed he was neurologically fit, which helped him heal himself. 

The adjacent photo shows how Dr. Hart obtains heart rate data on his patients, through an accurate sensor attached to the bottom of the earlobe.  

Knowing when and when not to adjust is the topic of interest in Study #14 above and is an important aspect of care at Hart Chiropractic.
