Thickness of the Plantar Fascia in Stretched and Relaxed Positions in Patients With Plantar Fasciopathy

Completed

• Conditions: Plantar Fasciopathy

• Registration Number: NCT03291665
• Lead Sponsor: Aalborg University

Brief Summary

This study will compare the thickness of the plantar fascia in stretched and relaxed positions in patients with plantar fasciopathy using ultrasonography.

Detailed Description

The purpose of this observational study is to compare the thickness of the plantar fascia in stretched and relaxed positions of the most symptomatic heel in patients with plantar fasciopathy using ultrasonography.

In addition to this, we will compare measurements of the thickness of the plantar fascia in sagittal versus transversal transducer positions, compare pressure pain thresholds at the most tender spot of the plantar fascia in stretched and relaxed position using pressure algometry and investigate the association between the thickness of the plantar fascia and the pressure pain threshold. All measurements are performed bilaterally starting with the most symptomatic foot.

To compare thickness and pressure pain thresholds in stretched and relaxed positions of the plantar fascia paired-t-tests are used. To compare the most and least symptomatic sides paired-t-tests will be used.

The association between the thickness of the plantar fascia and pressure pain threshold will be investigated using the Pearson's correlation coefficient.

Primary Outcome Measures

Name	Time	Method
Thickness of the plantar fascia in sagittal plane	Immediately after eligibility has been confirmed	The thickness will be measured in mm in stretched and relaxed positions using ultrasonography with a sagittal transducer position.

Secondary Outcome Measures

Name	Time	Method
Pressure pain threshold	Immediately after eligibility has been confirmed	Measured in kPa at the most tender spot of the plantar fascia in stretched and relaxed position using pressure algometry. In non-symptomatic feet the antero-medial part of the calcaneus is used as the test site.
Thickness of the plantar fascia in transversal plane	Immediately after eligibility has been confirmed	The thickness will be measured in mm in stretched and relaxed positions using ultrasonography with a transversal transducer position
