- hypothesisCustom made orthotic insoles by a podiatrist are (cost)effective in reducing pain and improving function in patients with plantar fasciitis compared to sham orthotic insoles and education alone.

- InterventionsThe intervention group will receive custom made orthotic insoles from a participating podiatrist. One control group will receive a sham orthotic insole from a podiatrist while another control group will receive usual care only. All groups will receive education.
- Primary outcomePain at rest and during activity (11-point NRS scale) after 12 weeks follow-up
- Secondary outcomeFoot function (FFI) after 12 and 26 weeks follow-up
- Recovery (measured on a 7-point Likert scale ranging from “completely recovered” to “worse than ever”. Patients are deemed to be recovered if they rate themselves as “fully recovered” or “strongly recovered” on the Likert scale, whereas those who rate themselves as “slightly recovered” to “worse than ever” are deemed to be not recovered) after 12 and 26 weeks follow-up
- Pain at rest and during activity (11-point NRS scale) after 26 weeks follow-up
- Cost-effectiveness of the intervention after 26 weeks follow-up
- TimepointsSubjects will be asked to complete questionnaires at baseline, 2, 4, 6, 12 and 26 weeks follow-up.

- Brief summaryRationale
Plantar fasciitis is a common cause of foot pain that typically affect middle aged or older people but is also frequently seen in athletes. Many intervention strategies are applied in patients with plantar fasciitis; biomechanical treatment (including footwear modification like orthotic insoles) being one of the most applied. However the effectiveness of orthotic insoles has never been supported by high quality randomized controlled trials.
Objective
To examine the effectiveness of custom made orthotic insoles compared to sham insoles and usual care only in patients with plantar fasciitis in general practice and sports medicine practices.
Study design
The STAP study is a three-arm randomized controlled trial with a 26-week follow-up. Inclusion will be performed by general practitioners and sports physicians in the Netherlands.
Study population
Patients with complaints of fasciitis plantaris with a minimal duration of 2 weeks and aged between 18 and 65 are eligible for inclusion.
Interventions
Patients allocated to the intervention group will receive a custom made insole from a participating podiatrist. The first control group will receive a sham insole from a podiatrist and participants allocated to the second control group will receive usual care only by their general practitioner or sports physician. All groups will receive education.
Main endpoints
Pain during rest and activity after 12 weeks.
