Abstract
Two insoles designed to treat primary lesser metatarsalgia were compared in terms of their effect on plantar pressures and the subjective symptom relief.
A prospective single blind randomized trial of 8 weeks' treatment in 46 feet in 33 patients was performed. Subjective outcome measures were visual analogue pain scores and estimated compliance. Objective outcome measures were dynamic plantar pressures using the Musgrave Footprint® System.
In group 1 (Viscoped), 6 of 18 patients rated themselves much improved or somewhat improved, and in group 2 (Langer) the proportion was 12 of 15 (P = 0.02). Reported mean compliance was 16% higher in the Langer group. Plantar forefoot pressure was lowered by the insoles in all cases. The reduction was significantly greater (P < 0.001) in group 2, both in absolute pressure and as a percentage of initial pressure.
Group 2 (Langer) was significantly better in terms of reduction of peak metatarsal pressure. All the subjective outcome measures were better for the group 2 (Langer).
