Plantar fasciitis (PF) is the most common cause of heel pain. Approximately 10% of the population develops the condition throughout life. The main symptoms are morning pain and pain at the beginning of activities (after resting time). Pain is felt near the medial and proximal insertion of the plantar fascia in the calcaneus tuberosity, or, less commonly, under heel pad, which leads to dysfunction and limitation for recreational and work activities (Zhiyun et al., 2013; Riddle et al., 2003).
The etiology of PF is not yet clearly defined, but several risk factors such as bone spurs, flat feet, obesity, diabetes, rheumatic disorders, lower limb length discrepancy, improper footwear, long time in orthostasis and runner athletes have been considered as part of such risks (Zhiyun et al., 2013; MohseniBandpei et al., 2014).
