Plantar Pressure Distribution

Background: Excessive body weight seems to be a risk factor for foot loading. We sought to investigate the effect of different body mass index (BMI) levels on plantar pressure distribution during walking. Methods: In total, 163 women aged 45 to 65 years (mean ± SD: age, 57.4 ± 5.3 years; BMI, 27.0 ± 5.3) participated in the study. The women were divided, on the basis of BMI, into a normal-weight, overweight, or obese group. The study used the four following plantar pressure parameters (PPPs): contact percentage, absolute pressure impulse, relative pressure impulse, and absolute peak pressure, which were recorded in ten foot regions using a pressure measurement system. Results: The normal-weight group, compared with the overweight and obese groups, had significantly lower absolute PPP values. In the hallux, second through fifth metatarsals, midfoot, and heel regions, we observed significant between-group differences in the two absolute PPPs (peak pressure and pressure impulse) (P < .001). Between-group differences in the relative PPPs were found in the fourth metatarsal, midfoot, and medial heel (relative impulse) and in the second metatarsal (contact percentage) (P < .001). Conclusions: Higher BMI values correspond to a higher load on the foot during walking in women. The relative foot load in obese women is characterized by a pressure increase in the lateral forefoot and midfoot and by a pressure decrease in the medial heel.

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.

Background Flatfoot, or pes planus, is one of the most common foot posture problems in children that may lead to lower-extremity pain owing to a potential increase in plantar pressure. First, we compared plantar pressure distribution between children with and without flatfoot. Second, we examined the reliability and accuracy of a simple metric for characterization of foot posture: the Clarke angle. Third, we proposed a mathematical model to predict plantar pressure magnitude under the medial arch using body mass and the Clarke angle. Methods Sixty children with flatfoot and 33 aged-matched controls were recruited. Measurements included in-shoe plantar pressure distribution, ground reaction force, Clarke angle, and radiography assessment. The measured Clarke angle was compared with radiographic measurements, and its test-retest reliability was determined. A mathematical model was fitted to predict plantar pressure distribution under the medial arch using easy-to-measure variables (body mass and the Clarke angle). Results A high correlation was observed between the Clarke angle and radiography measurements (r &gt; 0.9; P &lt; 10−6). Excellent between- and within-day test-retest reliability for Clarke angle measurement (intraclass correlation coefficient, &gt;0.9) was observed. Results also suggest that pressure magnitude under the medial arch can be estimated using the Clarke angle and body mass (R2 = 0.95; error, &lt;0.04 N/cm2 [2%]). Conclusions This study suggests that the Clarke angle is a practical, reliable, and sensitive metric for quantification of medial arch height in children and could be recommended for research and clinical applications. It can also be used to estimate plantar pressure under the medial arch, which, in turn, may assist in the timely intervention and prognosis of prospective problems associated with flatfoot posture.

The present study aims to evaluate changes in plantar pressure distribution after joint-preserving surgery for rheumatoid forefoot deformity. A retrospective study was performed on 26 feet of 23 patients with rheumatoid arthritis (RA) who underwent the following surgical combination: modified Mitchell’s osteotomy (mMO) of the first metatarsal and shortening oblique osteotomy of the lateral four metatarsals. Plantar pressure distribution and clinical background parameters were evaluated preoperatively and one year postoperatively. A comparison of preoperative and postoperative values indicated a significant improvement in the visual analog scale, Japanese Society for Surgery of the Foot scale, and radiographic parameters, such as the hallux valgus angle. A significant increase in peak pressure was observed at the first metatarsophalangeal joint (MTPJ) (0.045 vs. 0.082 kg/cm2; p < 0.05) and a significant decrease at the second and third MTPJs (0.081 vs. 0.048 kg/cm2; p < 0.05, 0.097 vs. 0.054 kg/cm2; p < 0.05). While overloading at the lateral metatarsal heads following mMO has been reported in previous studies, no increase in peak pressure at the lateral MTPJs was observed in our study. The results of our study show that this surgical combination can be an effective and beneficial surgical combination for RA patients with mild to moderate joint deformity.

The Relationship

Abstract The relationship between generalized joint laxity and plantar pressure distribution of the foot and the potential implications for lower extremity injury have not been studied.Context: To determine the relationship between generalized joint laxity and dynamic plantar pressure distribution. We hypothesized that individuals with greater generalized joint laxity, or hypermobility, would have greater dynamic medial midfoot pressure and loading during walking than nonhypermobile individuals.Objective: Case control.Design: Institutional biomechanics laboratory.Setting: Participants included 112 female soccer players between 11 and 21 years of age.Patients or Other Participants: Each participant was tested for generalized joint laxity using the Beighton and Horan Joint Mobility Index (BHJMI; range, 0–9) and was categorized as having either high (BHJMI score ≥4) or low (BHJMI score &lt;4) generalized joint laxity. Peak pressure and maximum force were calculated from a dynamic, barefoot plantar pressure distribution system.Main Outcome Measure(s): Peak pressure and maximum force were greater in the 27 participants categorized as having high generalized joint laxity than in the 85 participants categorized as having low generalized joint laxity. The midfoot region exhibited greater loading in participants with high generalized joint laxity than in the other participants. We found an effect of BHJMI classification in the medial midfoot; peak pressure in the dominant (F1,109  =  11.262, P  =  .001) and nondominant (F1,109  =  14.32, P &lt; .001) sides and maximum force in the dominant (F1,109  =  7.88, P  =  .006) and nondominant (F1,109  =  9.18, P  =  .003) sides were greater in the high generalized joint laxity group than in the low generalized joint laxity group.Results: Athletes classified as having high generalized joint laxity demonstrated increased midfoot loading. Delineation of risk factors for medial collapse of the foot, which include hypermobility in athletes, may help clinicians evaluate and prevent lower extremity injury with treatments, such as orthoses.Conclusions:

Loss of heel pad elasticity has been suggested as one of the possible explanations of heel pain. This study aimed to determine the effect of heel pad thickness and its compressibility to heel pressure distribution, in 47 (94 feet) normal subjects and 59 (94 feet) patients with heel pain, using radiological measurements and EMED-SF (Novel, Munich) plantar pressure distribution measurement system. Both heels of the patients and control group were radiographed with and without weight bearing. The ratio of the heel pad thickness in loading to unloading position was defined as “the heel pad compressibility index.” The plantar peak pressure of the heel was measured at heel strike phase of the gait cycle. The compressibility index for control and patient groups were found to be 0.60 and 0.69, respectively. The peak pressure under the heel pad was recorded to be 28.4 N/cm2 for patients and 31.7 N/cm2 for control group. No significant difference was found for heel pad compressibility index and heel pad pressures between patient and control groups (p>0.05). This study revealed that there is no relationship between heel pad compressibility and pressure distribution of the heel pad both in control and patient group. We feel the flexibility of the heel pad does not have any influence on heel pain syndromes.

Foot Orthosis

Background:Higher plantar pressures at the medial forefoot are reported in hallux valgus. Foot orthoses with medial arch support are considered as an intervention in this pathology. However, little is known about the effect of foot orthoses on plantar pressure distribution in hallux valgus.Objectives:To investigate the effect of a foot orthosis with medial arch support on pressure distribution in females with mild-to-moderate hallux valgus.Study design:Quasi-experimental.Methods:Sixteen female volunteers with mild-to-moderate hallux valgus participated in this study and used a medial arch support foot orthosis for 4 weeks. Plantar pressure for each participant was assessed using the Pedar-X®in-shoe system in four conditions including shoe-only and foot orthosis before and after the intervention.Results:The use of the foot orthosis for 1 month led to a decrease in peak pressure and maximum force under the hallux, first metatarsal, and metatarsals 3–5 ( p < 0.05). In the medial midfoot region, peak pressure, maximum force, and contact area were significantly higher with the foot orthosis than shoe-only before and after the intervention ( p = 0.00).Conclusion:A foot orthosis with medial arch support could reduce pressure beneath the hallux and the first metatarsal head by transferring the load to the other regions. It would appear that this type of foot orthosis can be an effective method of intervention in this pathology.Clinical relevanceFindings of this study will improve the clinical knowledge about the effect of the medial arch support foot orthosis used on plantar pressure distribution in hallux valgus pathology.

Prospective Longitudinal

Background: The intention of this investigation was to longitudinally describe and compare the plantar pressure distribution in orthostatic posture and gait throughout pregnancy. Methods: A prospective longitudinal observational study was conducted with six pregnant women (mean ± SD age, 32 ± 3 years) with a mean ± SD weight gain of 10.0 ± 1.4 kg. Peak pressure, contact time, contact area, and maximum force in five plantar areas were evaluated using capacitive insoles during gait and orthostatic posture. For 1 year, the plantar pressures of pregnant women were evaluated the last month of each trimester. Comparisons among plantar areas and trimesters were made by analysis of variance. Results: For orthostatic posture, no differences in contact time, contact area, peak pressure, and maximum force throughout the trimesters were found. During gait, peak pressure and maximum force of the medial rearfoot were reduced from the first to third and second to third trimesters. Maximum force increased at the medial forefoot from the first to second trimester. Contact area increased at the lateral rearfoot from the second to third trimester and at the midfoot from the first to third trimester. Contact time increased at the midfoot and medial and lateral forefoot from the first to third trimester. Conclusions: Pregnant women do not alter plantar pressure during orthostatic posture, but, during gait, the plantar loads were redistributed from the rearfoot (decrease) to the midfoot and forefoot (increase) throughout pregnancy. These adjustments help maintain the dynamic stability of the pregnant woman during locomotion. (J Am Podiatr Med Assoc 101(5): 415–423, 2011)

(1) Background: The aim of this study was to evaluate differences in the static and dynamic distribution of foot pressure on the ground and to investigate the relationships between body mass index (BMI) and mean variables of plantar pressure between soccer players and their non-athlete peers. (2) Methods: The study involved 18 first-division Polish soccer players and 30 non-athlete physiotherapy students. The research experiment was conducted using the FreeMed platform. Basic descriptive statistics were calculated to summarize the variables. Additionally, in the static and dynamic tests, Spearman’s rank correlations between body mass index (BMI) and plantar load were calculated. (3) Results: Statistically significant differences between groups were observed in the loading of the dominant limb. A statistically significant correlation between BMI and loading of both limbs was found in the static test and between BMI and loading of the dominant limb in the dynamic test. (4) Conclusions: The baropodometric mat used in our study helped determine the plantar pressure distribution of soccer players and their non-athlete peers. Correlation analysis revealed that BMI was only associated with the mean plantar pressure of the dominant limb in the control group. Further research on a larger group of athletes is needed to determine how much sporting activity may affect the development to modifications within feet in soccer players.
