3 total sessions, one per week, of focused extracorporeal shockwave treatment with a frequency of 5 Hz, an energy flux density of 0.05-0.167 mJ (millijoule)/mm2 administered on 3 or 4 myofascial points (identified based on Fascial Manipulation principles), 1500 shocks per point.

3 total sessions, one per week, of focused extracorporeal shockwave treatment, with a frequency of 5 Hz, an energy flux density of 0.32 mJ(millijoule)/mm2, for a total of 2000 shocks administered on the area of the painful heel on the medial calcaneal tubercle.

3 weekly sessions of focused Extracorporeal Shockwave treatment with a frequency of 5 Hz, an energy flux density of 0.05-0.167 mJ(millijoule)/mm2, administered on 3-4 myofascial lower limb trigger points (identified according to the approach of Fascial Manipulation), 1500 shocks per point.

Self-administered questionnaire. It consists in 17 items divided into 3 subscales: pain (5 items), disability (9 items), and limitation of activity (3 items). The items are rated on a Visual Analogue Scale (VAS), from 0 to 10.

A score is calculated for every subgroup of items, and then the final score is calculated by adding the subscale's scores and dividing the result by 170. The final percentage score is between 0% (best outcome) and 100% (worst outcome).

Self-administered questionnaire. It consists of 42 items divided in 5 subscales: pain (9 items), other symptoms (7 items), function in activities of daily living (17 items), function in sports and recreation (5 items), and foot-and-ankle related quality of life (4 items).

The questions are made to be answered with qualitative terms (None, Mild, Moderate, Severe, Extreme) or temporal terms (Never, Rarely, Sometimes, Often, Always) corresponding to a numeric value, from 0 to 4. The score for each subdomain as well as the total FAOS is then calculated and normalized to a 0-100 scale, where 0% is the worst outcome and 100% the best outcome. Then, a final, global percentage score, from 0% (worst outcome) to 100% (best outcome), is given.
