The effect of orthotic treatment on midfoot osteoarthritis assessed using specifically designed patient evaluation questionnaires

Midfoot osteoarthritis (OA) is a degenerative condition of the foot that can be treated non-operatively by the use of orthotics. This prospective study was conducted to determine the effects of custom-made semi-rigid foot orthoses (FOs) and rigid carbon fibre (CF) footplates for the treatment of midfoot OA evaluated using specifically designed questionnaires.

Subjects were required to complete pre-treatment questionnaires prior to receiving orthotic treatment. All subjects received a pair of custom-made full-length semi-rigid FOs and 36 subjects also received CF footplates that were incorporated into the soles of the shoes worn on the symptomatic feet.
