Walking Speeds

Among people with diabetes mellitus (DM), the two common strategies for decreasing peak plantar pressure (PPP) to reduce diabetic foot ulcers (DFUs) risks are to modify walking speeds and to change insole materials. This study reviewed the PPP reduction based on various walking speeds and insole materials. The articles were retrieved from four major scientific databases and manual search. We identified 1585 articles, of which 27 articles were selected for full-text analysis. We found that in faster walking speeds, the forefoot PPP was higher (308 kPa) than midfoot (150 kPa) and rearfoot (251 kPa) PPP. The appropriate walking speed for reducing the forefoot PPP was about 6 km/h for non-DM and 4 km/h for DM people. The forefoot PPP in DM people was 185% higher than that of non-DM people. Ethylene–vinyl acetate (EVA) insole material was the most popular material used by experts (26%) in the forefoot and reduced 37% of PPP. In conclusion, the suitable walking speed for DM was slower than for non-DM people, and EVA was the most common insole material used to decrease the PPP under the forefoot. The clinicians might recommend DM people to walk at 4 km/h and wear EVA insole material to minimize the DFUs.

Increased plantar pressure has been found to be related with greater risk of falling. Although there is evidence suggesting that obesity is linked to foot disorders, the association between obesity and plantar pressure of older adults has been poorly investigated. The purpose of this study was to examine the association between obesity and plantar pressure distribution and to explore its relationship with body fat distribution. Two hundred and eleven older women took part in this cross-sectional study. Body mass index was taken for obesity classification. Whole body, android, and gynoid fat percentage was assessed using dual-energy x-ray absorptiometry. Peak plantar pressure was evaluated during gait using an Emed AT-4 pressure platform. Obese volunteers generated greater peak pressure at midfoot (187.26 kPa) compared to both normal weight (128.52 kPa, p < .001) and overweight (165.74 kPa, p < .001). Peak plantar pressure at midfoot was also greater in overweight compared to normal weight (p < .001). At forefoot, peak pressure was higher in the obese (498.15 kPa) compared to normal weight volunteers (420.41 kPa, p = .007). Additionally, whole body, android, and gynoid fat percentage were significantly associated with peak pressure at midfoot and forefoot. Therefore, clinicians dealing with falls should consider the effect of increased body weight on plantar pressure.

Footwear Design

The quantification of plantar pressure distribution is widely done in the diagnosis of lower limbs deformities, gait analysis, footwear design, and sport applications. To date, a number of pressure insole layouts have been proposed, with different configurations according to their applications. The goal of this study is to assess the validity of a 16-sensors (1.5 × 1.5 cm) pressure insole to detect plantar pressure distribution during different tasks in the clinic and sport domains. The data of 39 healthy adults, acquired with a Pedar-X® system (Novel GmbH, Munich, Germany) during walking, weight lifting, and drop landing, were used to simulate the insole. The sensors were distributed by considering the location of the peak pressure on all trials: 4 on the hindfoot, 3 on the midfoot, and 9 on the forefoot. The following variables were computed with both systems and compared by estimating the Root Mean Square Error (RMSE): Peak/Mean Pressure, Ground Reaction Force (GRF), Center of Pressure (COP), the distance between COP and the origin, the Contact Area. The lowest (0.61%) and highest (82.4%) RMSE values were detected during gait on the medial-lateral COP and the GRF, respectively. This approach could be used for testing different layouts on various applications prior to production.
