Summary
Brief summary
Plantar fasciitis is a condition that causes pain in the arch or heel of the foot. It is commonly treated by using foot orthoses (orthotics or shoe insoles). This trial aimed to evaluate the effect of three types of foot orthoses used to treat plantar fasciitis. The trial’s primary hypotheses were (i) do commonly prescribed foot orthoses reduce pain in people with plantar fasciitis, and (ii) do commonly prescribed foot orthoses improve function in people with plantar fasciitis. The trial assessed changes in pain and function in both the short-term (i.e. after 3 months of treatment) and the long-term (i.e. after 12 months of treatment).
