Effect of pronation and supination orthosis on Morton's neuroma and lower extremity function

Twenty-three adult patients with Morton's neuroma of one foot were randomized to receive in-shoe orthoses made from a hard, compressed, felt material that would either pronate or supinate both feet. The response of the neuroma pain was measured using subjective visual analogue scales, an objective examination, and the MACTAR patient-specific measure of maximal function. The development of any other lower limb symptoms was also recorded. The pain associated with Morton's neuroma was not significantly altered by changing the position of the foot with the compressed felt orthosis. Forcibly pronating the foot did not produce a significant incidence of lower limb symptoms in the short term.
