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.

Inclusion criteria
* History of plantar heel pain of at least 3 months * Clinical presentation of pain and/or tenderness to palpation in the area of the medial tubercle of the calcaneus * Average intensity of pain in the previous week equal to or greater than 3 on an 11-point visual analog scale (VAS) * Thickness of symptomatic plantar fascia of 4 mm or greater
Exclusion criteria

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| 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
| Measure | Time frame | Description |
|---|---|---|
| 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 |
