Pressure Changes

Normal adult plantar pressures were measured during both level and sideslope walking. Sideslope pressures increased, depending on the relative position of the foot on the slope. With upslope placement, pressures increased significantly at the midfoot (≈20%) and fifth metatarsal (≈16%). With downslope placement, pressure increased predominantly beneath the first metatarsal (≈11%). Pressure changes were relatively small at the heel (≈3%) and central metatarsals (≈4%). Significant increases occurred on sideslopes as small as 2°. Since gradients of this size are likely to be encountered commonly in outdoor daily activities, this finding may have substantial implications for individuals with peripheral neuropathy.

Objective: The gold standard for offloading neuropathic forefoot and midfoot wounds is the total contact cast (TCC). However, in practice TCC is rarely used and is contraindicated in patients with fluctuating oedema, poor perfusion, lack of adequate tissue oxygenation and morbid obesity. It can also be too restrictive for patients, inevitably resulting in treatment rejection and delayed healing. This paper examines the role of shoe-based offloading devices as an alternative in reducing plantar pressure and optimising the healing of neuropathic ulcers. Method: Healthy subjects were recruited and fitted for two types of pixelated insoles: PegAssist (PA) insole system (Darco International, US) and FORS-15 (FORS) offloading insole (Saluber, Italy). An area of discreet, elevated high pressure was created by adding a 1/4-inch-thick felt pad to the plantar skin under the first metatarsal head. Subjects walked barefoot in surgical shoes with standard insoles (Condition 1), barefoot in pixelated insoles (Condition 2), barefoot with pixels removed (Condition 3). Dynamic plantar pressures were measured using F-Scan and the results were analysed to determine plantar pressure changes in each condition. Results: Using PA, the percentage reduction of plantar pressure (kPa) under the first metatarsal between Condition 1 and Condition 2 was 10.54±15.81% (p=0.022), between Condition 2 and Condition 3 was 40.13±11.11% (p<0.001), and between Condition 1 and Condition 3 was 46.67±12.95 % (p<0.001). Using FORS, the percentage reduction between Condition 1 and Condition 2 was 24.25±23.33% (p=0.0029), between Condition 2 and Condition 3 was 23.61±19.45% (p<0.001), and between Condition 1 and Condition 3 was 43.39±18.70% (p<0.001). A notable difference in the findings between the two insoles was the presence of a significant edge effect associated with PA, indicating that the offloading was not entirely successful. No edge effect was detected with FORS. Conclusion: Our current analysis shows that pixelated insoles exhibit potential for supplemental offloading in surgical shoes. These devices could provide an alternative way for physicians to offload plantar wounds and expedite closure for patients that cannot tolerate a TCC or other restrictive devices.

Background: The aim of this study was to observe the pressure changes in the felt padding used to off-load pressure from the first metatarsal head, the effects obtained by different designs, and the loss of effectiveness over time. Method: With a study population of 17 persons, two types of 5-mm semicompressed felt padding were tested: one was C-shaped, with an aperture cutout at the first metatarsophalangeal joint, and the other was U-shaped. Pressures on the sole of the foot were evaluated with a platform pressure measurement system at three time points: before fitting the felt padding, immediately afterward, and 3 days later. Results: In terms of decreased mean pressure on the first metatarsal, significant differences were obtained in all of the participants (P &lt; .001). For plantar pressures on the central metatarsals, the differences between all states and time points were significant for the C-shaped padding in both feet (P &lt; .001), but with the U-shaped padding the only significant differences were between no padding and padding and at day 3 (P = .01 and P = .02). Conclusions: In healthy individuals, the U-shaped design, with a padding thickness of 5 mm, achieved a more effective and longer-lasting reduction in plantar pressure than the C-shaped design.

Background No detailed comparative studies have been performed regarding plantar pressure changes between proximal dome and distal chevron osteotomies. This study aimed to compare radiographic and plantar pressure changes after distal chevron and proximal dome osteotomies and to investigate the effect of radiographic and plantar pressure changes on clinical outcomes. Methods This study included 26 and 22 patients who underwent distal chevron and proximal dome osteotomies, respectively. Visual analog scale (VAS) and American Orthopaedic Foot & Ankle Society (AOFAS) forefoot scores were used to evaluate pain and functional outcomes. Hallux valgus angle, intermetatarsal angle, talar–first metatarsal angle, and calcaneal inclination angle were measured in the evaluation of radiographic outcomes. Preoperative and postoperative plantar pressure changes were evaluated. Results There were no statistically significant differences between the two groups in age, body mass index, or AOFAS forefoot and VAS scores. In the proximal dome group, the pressure measurement showed significant lateralization of the maximal anterior pressure point in the forefoot (P &lt; .001). In addition, the postoperative calcaneal inclination angle was significantly lower (P = .004) and the talar–first metatarsal angle was significantly higher (P &lt; .001) in the proximal dome group. Postoperative transfer metatarsalgia was observed in one patient (3.8%) in the distal chevron group and five (22.7%) in the proximal dome group (P &lt; .05). Conclusions Proximal dome osteotomy led to more lateralization of the maximum anterior pressure point, decreased calcaneal inclination angle and first metatarsal elevation, and related higher transfer metatarsalgia.

A Prospective Study

Abstract Background: Talipes equinovarus, also known as clubfoot, is a congenital anomaly that affects one newborn per 1000 live births. Its standard treatment strategy is the Ponseti casting management. This study aims to report the long-term outcomes of the Ponseti treatment in Iran.Methods: A prospective cohort study was enrolled to evaluate clinical outcomes, radiological results, pedobarographic measurements, and quality of life after the Ponseti treatment in patients with clubfoot who were followed for at least five years.Results: In this study, 25 clubfeet of 18 patients were included. Significant reductions in Pirani, Dimeglio, and CAP scores, improved ankle dorsiflexion, and acceptable pedobarographic indices were observed in this study. From the radiological evaluation indices, the calcaneal pitch and lateral talus-first metatarsal angles were significantly reduced. The quality of life of patients after five years of treatment was favorable, which was better in females. This study showed that the results of the Ponseti treatment remained acceptable after five years.Conclusions: The Ponseti management for clubfoot in the long term appears to maintain significant improvements. However, the rate of recurrence – albeit without disruption to daily activities - cannot be ignored.

Background: Foot pain and paresthesia are common in cycling, due to plantar pressure and repetitive loading. Objectives: The aim was to investigate the effect of foot insoles on plantar pressure of the foot in motorcycling, as well as self-reported comfort. Study design: A randomized crossover clinical trial. Methods: A flexible foot pressure mat (GP MobilData WiFi® Gebiomized®) with different sizes was utilized. Results: Maximum pressure values occurred predominantly in the hallux with 4.90 ± 1.19 N/cm2, followed by second and third metatarsal areas with 4.57 ± 0.73 N/cm2, followed by the first metatarsal area with 4.30 ± 0.96 N/cm2, and followed by the fourth and fifth metatarsal areas with 3.22 ± 0.89 N/cm2 when using the control foot insole and using aluminum foot insole, which reduces maximum pressure to 1.55 ± 0.34, 1.56 ± 0.75, 1.09 ± 0.43, and 1.07 ± 0.59 N/cm2, respectively ( p < 0.001), with an effect size of 3.828, 4.067, 4.315, and 2.847, respectively. Conclusion: The use of an aluminum foot insole significantly reduced maximum pressure during motorcycling. Clinical relevance In this study, an aluminum insole in a motorcycling boot was shown to decrease maximum pressure on the foot. Comfort was significantly higher than that from ethylene vinyl acetate or commercial boot inserts. This increased comfort and decreased pressure should result in increased safety and control for motorcyclists.
