Plantar Fasciitis Randomized Clinical Control Trial

The primary aim of this clinical experiment is to compare, in terms of pain relief measured using the 10-cm visual analog scale (VAS) pain score (5-7), the clinical results of ultrasound-guided injection (USGI) versus anatomic topography-guided injection (ATGI) of corticosteroid for the treatment of proximal PF. Secondary aims will be to compare foot-related quality of life, as measured using the Foot Function Index (FFI)and the Bristol Foot Score (BFS), between the injection groups, and also to compare the pre-injection to late-term post-injection thickness of the plantar fascia as measured in the nested USGI group.
