Foot insoles are widely used to reduce excessive pressure exerted on the plantar surface of the foot and prevent diabetic foot ulceration. The objective of this study was to investigate the effects of the metatarsal pad on pressure on the forefoot area.
This randomized crossover clinical trial was conducted on 18 volunteers (5 women and 13 men) with diabetic peripheral neuropathy. Plantar pressure was recorded while participants walked over a plantar pressure platform in three random conditions of barefoot, with a placebo intervention, and with a metatarsal pad. The processed variables were statistically analyzed using repeated measure one-way ANOVA.
The metatarsal pad caused a significant reduction in mean pressure on the forefoot compared to the barefoot and placebo conditions (P The metatarsal pad transfers the forefoot load to the midfoot area, thereby, reducing the pressure exerted on the forefoot. This finding implies that using a metatarsal pad can be an effective intervention to prevent diabetic foot ulceration.

Rheumatoid arthritis is a chronic inflammatory disease which causes structural and functional changes in foot joints and results in alteration of plantar pressures. Therefore, the aim of this study was to investigate the immediate effect of insole with medial longitudinal arch support and metatarsal pad on plantar pressure distribution in females with rheumatoid arthritis. This was a quasi-experimental study in which 15 volunteer females with rheumatoid arthritis were recruited using no-probability simple sampling method. Plantar pressures were assessed using Pedar-X system in four anatomical foot region in two conditions of walking with and without foot orthosis. Average maximum pressures (Kilopascal) were calculated in each region. Foot orthosis with medial longitudinal arch support and metatarsal pad reduced plantar pressure in heel (P< 0.015), metatarsal heads (P< 0.03) and increased pressure in mid-foot area (P< 0.00). However, no significant differences in average maximum pressure were observed between two assessed conditions in the toe area. The findings of the present study revealed that the orthosis with medial longitudinal arch support and metatarsal pad corrects increased pressure on heel and metatarsal heads in rheumatoid arthritis. It could increase plantar pressure in mid-foot while decrease it in metatarsal heads and heel regions. Therefore, this orthosis is recommended to be used as a treatment in this pathology in order to re-distribute the foot pressures more normally.
