The histopathology of plantar fasciitis (PF), even though poorly understood, presents a lot of similarities with tendinopathy; degenerative changes, deterioration of collagen fibers, increased secretion of ground substance proteins, focal areas of fibroblast proliferation, increased vascularity et cetera.
The results point towards superiority of the high load strength training protocol in reducing pain and improving foot function after 3 months compared to specific plantar fascia stretching. This study provides more ground for the similarities between PF and tendinopathy and adds new knowledge on the positive effect of a new, simple, progressive exercise protocol for a debilitating condition such as PF.
