“…The current study provided a deeper insight into the plantar pressure patterns of people with HMSN by evaluating plantar pressure patterns for each of the four foot deformity categories separately. Although clear differences in plantar pressure pattern were seen between the HMSN subgroups, all subgroups showed an increased pressure underneath the midfoot, which is in line with previous findings [ 5 – 8 ]. Prior studies that evaluated pressure underneath the rearfoot showed inconsistent results [ 5 – 8 ], while our study revealed decreased pressure underneath the rearfoot in people with HMSN.…”

“…One way to evaluate foot function during walking is by measuring plantar pressure patterns. In people with HMSN, a decreased contact surface area and increased mean pressures, peak pressures, and pressure-time integrals have been found [ 5 – 7 ]. However, previous research has been inconclusive regarding the foot regions under which the pressures and pressure-time integrals are increased.…”

“…However, previous research has been inconclusive regarding the foot regions under which the pressures and pressure-time integrals are increased. This might be due to the variation in foot deformities that were included in previous studies without clearly distinguishing between them [ 5 – 7 ] since plantar pressure distributions are directly related to foot deformities [ 8 ]. For a better clinical and scientific evaluation of foot function and for the evaluation of surgical interventions, plantar pressure patterns should, therefore, be investigated for all four foot deformity categories separately.…”

“…Previous research divided the foot into a fixed number of anatomical regions, often called “masks”, to study the plantar pressure of different foot regions. However, definitions of these foot regions were inconsistent among studies [ 5 – 7 ], which makes it difficult to compare their results. Furthermore, applying a masking method results in loss of information on the complete plantar pressure pattern, comprising the plantar pressure distributions within the masks.…”

Background Hereditary motor and sensory neuropathies (HMSN), also known as Charcot-Marie-Tooth disease, are characterized by affected peripheral nerves. This often results in foot deformities that can be classified into four categories: (1) plantar flexed first metatarsal, neutral hindfoot, (2) plantar flexed first metatarsal, correctable hindfoot varus, (3) plantar flexed first metatarsal, uncorrectable hindfoot varus, and (4) hindfoot valgus. To improve management and for the evaluation of surgical interventions, a quantitative evaluation of foot function is required. The first aim of this study was to provide insight into plantar pressure of people with HMSN in relation to foot deformities. The second aim was to propose a quantitative outcome measure for the evaluation of surgical interventions based on plantar pressure. Methods In this historic cohort study, plantar pressure measurements of 52 people with HMSN and 586 healthy controls were evaluated. In addition to the evaluation of complete plantar pressure patterns, root mean square deviations (RMSD) of plantar pressure patterns from the mean plantar pressure pattern of healthy controls were calculated as a measure of abnormality. Furthermore, center of pressure trajectories were calculated to investigate temporal characteristics. Additionally, plantar pressure ratios of the lateral foot, toes, first metatarsal head, second/third metatarsal heads, fifth metatarsal head, and midfoot were calculated to measure overloading of foot areas. Results Larger RMSD values were found for all foot deformity categories compared to healthy controls (p < 0.001). Evaluation of the complete plantar pressure patterns revealed differences in plantar pressure between people with HMSN and healthy controls underneath the rearfoot, lateral foot, and second/third metatarsal heads. Center of pressure trajectories differed between people with HMSN and healthy controls in the medio-lateral and anterior-posterior direction. The plantar pressure ratios, and especially the fifth metatarsal head pressure ratio, differed between healthy controls and people with HMSN (p < 0.05) and between the four foot deformity categories (p < 0.05). Conclusions Spatially and temporally distinct plantar pressure patterns were found for the four foot deformity categories in people with HMSN. We suggest to consider the RMSD in combination with the fifth metatarsal head pressure ratio as outcome measures for the evaluation of surgical interventions in people with HMSN.

“…One way children’s feet are assessed in clinical environments is through measuring and understanding dynamic plantar pressure patterns [ 4 ]. It is not typical that young children to have regular foot assessments [ 5 ] unless they have complex health conditions [ 6 , 7 ]. Due to this, there is little normative information about pressure distribution and changes for young children.…”

There is a rapid increase in plantar pressure from the infant to toddler stage, yet little is known about the reasons for this change. More information about plantar pressure distribution can help clinicians identify early-stage foot-related diseases that may occur during transitions from childhood to adulthood. This information also helps designers create shoes that adapt to different needs. This research describes the development of a low-cost, built-in shoe plantar pressure measurement system that determines foot pressure distribution in toddlers. The study aimed to improve and provide data on pressure distribution during foot growth. This was accomplished by implementing a plantar pressure capacitive measurement system within shoes. The capacitive sensors were laminated using a copper tape sheet on plastic backing with adhesive, elastomer layers, and a combination of conductive and non-conductive fabrics. Constructed sensors were characterized using compression tests with repeated loads. Results demonstrated that the sensors exhibited rate-independent hysteresis in the estimation of pressure. This enabled a calibration model to be developed. The system can mimic more expensive plantar pressure measurement systems at lower fidelity. This emerging technology could be utilized to aid clinicians, researchers, and footwear designers interested in how pressure distribution changes from infants to toddlers.
