The diagnostic value of pedobarography

Area of Science:

• Biomechanics
• Medical Diagnostics
• Podiatry

Background:

• Pedobarography quantifies static and dynamic foot pressure, aiding clinical assessment.
• Clinical diagnosis and pedobarography results often show poor correlation, causing confusion.

Purpose of the Study:

• To evaluate the diagnostic validity of pedobarography for diseases causing abnormal plantar pressure.
• To assess the correlation between pedobarographic measurements and clinical findings in patients with excessive plantar pressure.

Main Methods:

• Analyzed 96 cases of patients with excessive plantar pressure symptoms (average age 50.9 years).
• Compared maximal peak pressure from static and dynamic pedobarographic measurements with clinical peak pressure, plantar ulcers, and calluses.
• Assessed diagnostic validity by comparing clinical peak pressure with pedobarographic numeric and graphic measurements.

Main Results:

• Diagnostic validity ranged from 17.7% to 51% for static and 13.5% to 49% for dynamic pedobarography.
• Low validity was observed for intractable plantar keratosis and rheumatoid arthritis-related calluses.
• High validity (57%-100%) was found for Charcot arthropathy with midfoot ulcers.

Conclusions:

• Pedobarography demonstrates low overall diagnostic validity for identifying various plantar conditions.
• Correlation between pedobarographic numeric and graphic pressure measurements and clinical presentation is often poor.
• Further research is needed to improve the clinical utility of pedobarography in diagnosing foot pathologies.
