Inclusion criteria

Inclusion criteria: Plantar heel pain for more than three months prior to recruitment, pain on palpation of the medial tubercle of the calcaneus or the proximal plantar fascia and pain during the first steps in the morning or after prolonged inactivity.

Design outcomes

Primary

Measure	Time frame
The strength of the foot and calf muscles is assessed using a 3-repetition maximum (3-RM) heel raise test. Measurements are taken at two time points: before the start of the intervention period and after completion of the intervention, thus after 6 weeks. Ankle joint mobility (range of motion) is measured using a goniometer. This is also assessed before and after the 6-week intervention. To determine functional changes in the foot, the German version of the Foot Function Index (FFI-D) is used. This is a validated German-language questionnaire that includes both a pain scale and a function scale. It is administered at two time points: prior to and after the 6-week intervention period.	—
