Custom foot orthoses improve first-step pain in individuals with unilateral plantar fasciopathy: a pragmatic randomised controlled trial.

ABSTRACT:

Background

Foot orthoses are routinely used to treat plantar fasciopathy in clinical practice. However, minimal evidence exists as to the effect of both truly custom designed foot orthoses, as well as that of the shoe the foot orthoses are placed into. This study investigated the effect of wearing custom foot orthoses and new athletic footwear on first-step pain, average 24-h pain and plantar fascia thickness in people with unilateral plantar fasciopathy over 12 weeks.

Methods

A parallel, three-arm randomised controlled trial with blinding of participants and assessors. 60 participants diagnosed with unilateral plantar fasciopathy were randomised to either custom foot orthoses and new shoes (orthoses group), a sham insole with a new shoes (shoe group) or a sham insole placed in the participant's regular shoes (control group). Primary outcome was first-step pain. Secondary outcomes were average 24-h pain and plantar fascia thickness measured on ultrasound. Outcomes were assessed at baseline, 4 week and 12 week trial time-points.

Results

At 4 weeks, the orthoses group reported less first-step pain (p?=?0.002) compared to the control group. At 12 weeks, the orthoses group reported less first-step pain compared to both the shoe (p?=?ConclusionsCustom foot orthoses in new shoes improve first-step pain and reduce plantar fascia thickness over a period of 12 weeks compared to new shoes alone or a sham intervention.
