Second Toe Systolic Pressure Measurements are Valid Substitutes for First Toe Systolic Pressure Measurements in
Summary
Second toe systolic pressure measurements are interchangeable with first toe measurements in diabetic patients. This finding provides a viable alternative when first toe assessment is not possible due to ulcers or amputation.
Area of Science:
- Vascular Medicine
- Diabetic Foot Care
- Podiatry
Background:
- Toe systolic pressure is crucial for vascular and diabetic foot assessments.
- Current practice often relies solely on first toe pressure due to limited evidence for other toes.
- Diabetic patients frequently present with first toe ulcers or amputations, hindering standard assessment.
Purpose of the Study:
- To investigate the interchangeability of second toe systolic pressure measurements with first toe measurements.
- To establish if second toe systolic pressure can serve as a reliable alternative in diabetic patients.
Main Methods:
- Prospective study involving 100 participants with diabetes mellitus.
- Duplicate systolic toe pressures measured on first and second toes using the Systoe Automated Toe Pressure System.
- Correlation analysis and Ordinary Least Products regression used to assess bias and interchangeability within 5-10 mmHg limits.
Main Results:
- High correlation (r=0.908, p<0.001) between first and second toe systolic pressures.
- 82% of measurement variations were explained by the corresponding toe measurement.
- Ordinary Least Products regression indicated no fixed or proportional bias; repeatability was 0.5%.
Conclusions:
- First study demonstrating interchangeability between second and first toe systolic pressures.
- Second toe systolic pressure is a valid alternative when first toe assessment is compromised in diabetic individuals.

01:28Special considerations while measuring blood pressure
When assessing blood pressure (BP), healthcare professionals must consider various factors and potential unexpected outcomes to ensure accurate readings and provide proper patient care. Adhering to these guidelines is essential to achieving the most reliable results.
Monitoring Both Arms:
Monitoring BP in both arms during the initial assessment is advisable, as the systolic value may differ by five to ten mm Hg between arms. For subsequent BP assessments, use the arm with the higher reading.
