Introduction:
Pulse pressure is an indicator of cardiovascular health and is the difference between systolic and diastolic blood pressures. An important etiologic consideration is autonomic nervous system balance. The purpose of this study is to observe pulse pressure changes following a six-week course of care utilizing an upper cervical technique.
Methods:
One hundred and thirty patients presenting in five different clinics were separated into three groups based on initial pulse pressure groups with 40 mmHg considered as normal: low (< 40 mmHg), medium (40-49 mmHg), and high (> 49 mmHg).
Results:
Pulse pressure reduced by 8.9 mmHg in the high group which was statistically significant (p < 0.01) with a large effects size of 0.8. Changes in the low and medium groups were not statistically significant (p < 0.05).
Conclusion:
In this observational study the group displaying the highest pulse pressure demonstrated statistically significant reduction in pulse pressure.

Pulse Rate and its Significance
Pulse rate, often measured in beats per minute (bpm), reflects the heart rate (HR), which is influenced by numerous factors such as stress, physical activity, and hormonal changes. A normal resting adult pulse rate falls...
